Automapper profile with constructor parameter. ConvertUsing(src => src.

Automapper profile with constructor parameter I was originally expecting "ForCtorParam" to work, but im still getting the same exception after adding it. Starting with version 13. Profile class, there are a couple issues here: The cfg. I'm trying to use AutoMapper to add in a model layer, and I want to make sure the default parameters win – Add a custom mapping expression, ignore, add a custom resolver, or modify the source/destination type For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters ===== Location -> LocationEntity (Destination member list) UserQuery+Location -> UserQuery+LocationEntity (Destination member list I did decide to create one AutoMapper profile per domain entity like the followin leaving only the constructor with no parameters because I want to set the profile's name. AUtomapper - custom property mapping. public class StockProfile : Profile { public StockProfile() { AutoMapper "needs to have constructor with 0 args or only optional args" when mapping class to record. ResolveUsing<CustomResolver, decimal>(src => src You will notice that because the mapped object is a OnlineOrder, AutoMapper has seen you have a more specific mapping for OnlineOrder than OrderDto, and automatically chosen that. Below example “SourceMappingProfile” is a profile class with constructor injection of service instance type i. . Inside my profile class: Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company public class AutoMapper: Profile { public AutoMapper() { CreateMap < Customer, getCustomerDto > (); } } In our controller we can make use of the auto mapper configuration that we have defined About theutz answer, there is no need to specify the IMapper mapper parameter at the controllers constructor. Make sure to add the AutoMapper using directive. I took the git, and added a method to return out the Im trying to get automapper to map the parent object within the parameter of ViewModelB and Model B. All Mappers works as expected, but for one - the only one - which uses a custom type converter. AddMaps method is called immediately during construction of the MapperConfiguration instance Provide constructor parameter AutoMapper can map to destination constructors based on source members: public class Source {public int Value CreateMap < Source, SourceDto > ()); If the destination constructor parameter names don’t match, you can modify them at config time: You can configure which constructors are considered for the destination object: Review the types and members below. Extensions. 0 the API of AutoMapper has been changed. Map<>() has no parameters for additional options or objects, unlike the normal AutoMapper. 13 1 Automapper not invoking constructor. AutoMapper provides configuration testing in the form of the AssertConfigurationIsValid method. Then create an IMappingAction class like this:. DependencyInjection package and inside your startup: services. When I use ProjectTo for mapping data from database to class, second paramter after _mapper. ProfileMap. You could override the mapping behaviour and, for example, configure it to invoke a specific constructor, but that basically defeats the purpose of AutoMapper because then you are doing the mapping manually, and you've only succeeded in adding a The parameter of the AddCharacter() This class derives from Profile. When invoking Map, you can configure the conversion context with your custom parameter(s) using the second callback argument. This parameter is of the same type for all members, but I do not know the value to supply until the point I want to do my mapping. That way, instances of your type can be created using new without any knowledge of what parameters are needed for the constructor expression. 3) Ensure you have not accidentally created more than one kernel. That's not an issue when I don't have custom constructor as you can see in first example. Fesslersoft. You can only inject into custom resolvers and converters. Same concept as Share Configuration using MappingProfile, AutomapperProfile has an optional protected get mappingConfigurations() that Current version of AutoMapper works as described below: Sorts destination type constructors by parameter count. As of AutoMapper 8. In equivalent terms what I want to do in one shot is: Calc c = mockMapper. Models. Maybe there is a way to register the Profile in dependency injection, but with my limited knowledge of the framework, I couldn't find a clue None of the constructors found with 'Autofac. Models ; namespace dotnet_rpg { public class AutoMapperProfile : Profile { public AutoMapperProfile UpdateBulletinCommand needs to have a constructor with 0 args or only optional args. Using AutoMapper on shared properties? 1. ConvertUsing(typeof(MyEnumConverter)); Since I want to use Localizer to convert Enum to string, MyEnumConverter has a constructor with parameter: public class MyEnumConverter : ITypeConverter<SomeEnumType, string> { private readonly IStringLocalizer<MyResource> AutomapperProfile enforces the sub-classes to implement a get profile() method that returns a MappingProfile. CreateMap<Journal, JournalDto>(); Now, Journal contains a member named RefTypeID, which corresponding value exists in another table in the database; to look up this value, I have a service which handles a simple int -> string request. ConvertUsing(src => src. When you want to project source values into a destination that does not exactly match the source structure, you must specify custom member mapping definitions. // there is some abstractions here, but MapperProfileProvider inherits AutoMapper. 0 you can use IMapper. However, if this logic pertains only to the mapping operation, it would clutter our This works fine on most occasions and is the recommended approach, to my knowledge. First add AutoMapper. ForCtorParam(ctorParamName: "ExtraId", m => m. Automapper Profile with service Dependency Injection can be defined as below. My Profile class is: public ApplicationUserResponseProfile(HttpRequestMessage httpRequestMessage) . Length); Takes first constructor which parameters match source properties (without any check for null value). Add a custom mapping expression, ignore, add a custom resolver, or modify the source/destination type For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters. AutoMapper can map to destination constructors based on source members: public class Source {public int Value CreateMap < Source, SourceDto >()); If the destination constructor parameter names don’t match, you can modify them at config time: You can configure which constructors are considered for the destination object: Goal: To inject IHttpContextAccessor as a dependency into autmapper profile 's constructor Why: I need to pass in the current user 's identity 's name as part of construction of one of my domain objects. Given that the only thing MappingProfile is doing in your example code is ignoring the Products property, this leads me to believe that MapperProfile is not being Add a custom mapping expression, ignore, add a custom resolver, or modify the source/destination type For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters ===== String -> User (Destination member list) System. Activators. First define the configuration using profiles . public MappingProfile() { For those using Catel. FullNameSupervisor, m => m. CreateMap<MySourceType, MyDestinationType>(); I would like to have a constructor of MyDestinationType which have a MySourceType parameter, then automatically initialize properties of the type under creation with the source like this: Regarding the implementation, we need a constructor with no parameter and then create a map for the necessary mapping. This means that now IMapper interface has a method ProjectTo (similar to Map). Create classes that inherit from Profile and put the configuration in the constructor: AutoMapper can map to destination constructors based on source members: If the destination constructor parameter names don’t match, you can modify them at config time: This works for For this project we were using profiles which were dynamically loaded inside the application using MEF and were using Autofac for dependency injection. OptProp, I have to pass it in via the constructor argument. Similarly, we can use the IMapper interface in the constructor to use the mapper object: It takes the source object as a parameter and returns the destination object after performing the object mapping. Automapper: passing parameter to Map method. It's not perfect, but it would be less misleading. Validate your configuration for details. But I dont fell so sure about that approach, I'm not so good in DDD but seems like this approach disrupts DDD. Mapping operation will be run as a micro task. Reflection. You could override the mapping behaviour and, for example, configure it to invoke a specific constructor, but that basically defeats the purpose of AutoMapper because then you are doing the mapping manually, and you've only succeeded in adding a After I configure one simple mapping for AutoMapper like: Mapper. I'm using automapper library to convert my Model into my ViewModel. FooDto needs to have a constructor with 0 args, only optional args, or only args whose value can be resolved from the source type. 6 In earlier versions the Configure method was used instead of a constructor. I created the following test app, and it does in fact run without any exceptions and puts a 3 into the Output window (as intended): and my Profile includs a map using TypeConverter: . Handling Dependency in Automapper Profile. Register ValueResolver with Parameterized Constructor (Service as a parameter) #3114. Regarding the implementation, we need a constructor with no parameter and then create a map for the necessary mapping. ResolveUsing<CustomResolver, decimal>(src => src I have the following AutoMapper profile: public class AutoMapperBootstrap : Profile { protected override void Configure() { CreateMap<Data. ctor(MapperConfigurationExpression configurationExpression) at AutoMapper. How inject service in AutoMapper profile class. Dependency Injection Examples ASP. Modified 8 years, 4 months ago. Builder; var builder = WebApplication. NET Core 2. Initialize in constructor. Create one list of types before add profile and pass it in the parameter. cs file to make it available throughout the application. How to register Automapper 5. Fortunately, AutoMapper provides a way to use constructor with parameters So we changed our Mapping Profile like below. IoC here is how you register AutoMapper. Add a custom mapping expression, ignore, add a custom resolver, or modify the source/destination type For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters ===== AutoMapper created this type map for you, but your types cannot be mapped using the current configuration. For example: I map entity from database to domain entity in domain enitie's constructor, and map domain entity to view entity in view entity constructor. To perform a mapping, call Since I dont want to use AutoMapper, I desided to map entities in their constructor. cs you'll need to add AutoMapper to the service collection. Matching constructor parameters will be mapped from the source, even if they are optional You can always rename things or use an explicit MapFrom. asax. I have a domain class and a DTO class as follows: public class Employee { public long Id {get;set;} public string Name {get;set;} public string Phone {get;set;} public string Fax {get;set;} public DateTime DateOfBirth {get;set;} } public class EmployeeDto { public long Id {get;set;} public string FullName {get;set;} public DateTime Hi @jbogard "owner" come from the getter of the BranchCollection Property. Map overloads that receive a context were removed Not needed, because the context is passed by default, so you can change the context instance you already have. AddProfile(new DtoToOtherProfile(new HttpContextAccessor())); //OR var The automapper configuration currently happens in a static class at the start of the program. It seems that if assembly scanning is enabled for the assembly that contains the Profile derived class that does not have a No-Args constructor, that AutoMapper tries to instantiate it even with an explicit registration. I am using Automapper (v5. MapFrom(s => s. See the Sample Console Applications below. ReverseMap(); That way, AutoMapper will know, from where the value should be taken and will map accordingly. @Dr. RecordId)); This fixes the problem where Automapper is expecting a default constructor, however the only element that is mapped is the record id. However, if this logic pertains only to the mapping operation, it would clutter our at AutoMapper. Finally I managed it to work by creating a base abstract class inheriting from AutoMapper. AddAutoMapper(); Then in your profile, just tell AutoMapper that you want your destination object constructed with the container: Type needs to have a constructor with 0 args or only optional args Parameter name: type. 0) and Ninject (v3. AspNetCore. DbExtraId)). DependencyInjection package to your project. However, the UserName property on the MembershipUser class has a no setter. Dtos. ForMember(dest => dest. Then I had one of those “eureka” moments when I was thinking about how Is it possible to ignore mapping a member depending on the value of a source property? For example if we have: public class Car { public int Id { get; set; } public string Code { get; set; } } public class CarViewModel { public int Id { get; set; } public string Code { get; set; } } AutoMapper can map to destination constructors based on source members: public class Source {public int Value CreateMap < Source, SourceDto >()); If the destination constructor parameter names don’t match, you can modify them at config time: You can configure which constructors are considered for the destination object: AutoMapper 9. Map<Opt>(scen))); That is, construct both the Calc and Opt from the same Scen. Parameters are what you declare in the constructor, arguments are what you pass when you call it) When querying the data with Dapper, it appears that Dapper first instantiates the class with a parameter-less constructor, and then "maps" the returned columns into the properties on the object. My configuration in startup is this: How to inject a service in AutoMapper Profile class? 7 How to use generic Profile with Automapper and Asp. SecuritySettings)' As of 6. In your case it is constructor with two parameters. DependencyInjection 11. ForMember(e => e. EntityFramework. AddProfile(new DtoToOtherProfile(new HttpContextAccessor())); //OR var Unless I include those two commented out lines in the AutoMapper Profile class -- the ones starting with ConstructUsing -- I get an exception, from AutoMapper, that it can only handle classes with constructors that have no parameters, or only optional ones. This is my profile for the above at the moment Queryable Extensions . What Dependency Injection Examples ASP. 3. The answer below for 5. Configurations In Profile Classes. Automapper using constructor with default parameters. Order -> OrderProcessor (Destination member list) No available constructor. Many things require a type to have a default constructor. e IEmployeeType. Specifying inheritance in derived classes Instead of configuring inheritance from the base class, you can specify inheritance from the derived classes: For those coming later, the method above is not preferred, as it has state inside profiles. GetParameters(). And then you let AutoMapper know in what assemblies those Create classes that inherit from Profile and put the configuration in the constructor: // This is the approach starting with version 5 public class OrganizationProfile : Profile { public OrganizationProfile () { CreateMap < Foo , FooDto > (); // Use CreateMap You can absolutely do exactly what you want using a custom ITypeConverter<TSource, TDestination> implementation. You define the configuration using profiles. DefaultConstructorFinder' on type 'LM. The old mapping profiles are build up hierarchical, where the abstract base class requires an argument of type IDatetime. Dependency Injection With Mapster. 2 Using AutoMapper 8 ProjectTo on DI instance AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and application layer. NET 6, Autofac for dependency injection, and AutoMapper for object mapping. SecuritySettings securitySettings' of constructor 'Void . InSingletonScope (); // This teaches Ninject how to create automapper instances say if for instance // MyResolver has a constructor with a parameter that needs to be injected Bind < IMapper > (). Ask Question Asked 11 years, 7 months ago. The final solution is that, first of all mapping data from database then, for mapping data to output model, we can assign value to ResolutionContext to pass value to Where in the Profile/Mapping is reading the value of the param? – Piotrek. Take a look at the corresponding pull request for further information. CreateMap<EntityDTO, Entity>(). One of the inspirations behind AutoMapper was to eliminate not just the custom mapping code, but eliminate the need for manual testing. The automapper configuration currently happens in a static class AutoMapper Documentation var config = new MapperConfiguration(cfg => cfg. When I have custom constructor I don't know how to pass property like opt => opt. To perform a mapping, call When querying the data with Dapper, it appears that Dapper first instantiates the class with a parameter-less constructor, and then "maps" the returned columns into the properties on the object. I have . I want to use custom ValueResolver in which it will get the logged user ID from IContext, so i need to pass implementation of IContext using Ninject. ctor(LMS. 1 to the latest version 9. CreateMap<Song, CreateSong>() . Ask Question I think you need to use ConstructUsing if you want to keep using AutoMapper and well defined records. 1 this code works properly but in 5 beta not I'm examining a project which uses AutoMapper and Microsoft. ForMember(destination => destination For various reasons I cannot access Calc. ForCtorParam("author", o => o. NET Core . It errors when trying to add the profile that there isn't a constructor with no parameters. 1. AutoMapper calls these configuration classes "Profiles. UrlHelper Pass the parameters (for example, a service) into the constructor of the Profile, and then you can use them in your CreateMap methods. Listing 2, is an example Profile that I could've used in the sample code -- it only AutoMapper allows now (I am not sure, since when) to map properties with private setters. 2 AutoMapping Object with Constructor Arguments. CreateBuilder(args); Advanced Mapping with Constructor Parameters. And then you let AutoMapper In fact, you can have a private parameterless constructor for Entity Framework (EF) and force the use of a public constructor with parameters when using in your code. Commented May 28, 2017 at 18:11 @MartinDawson is right. cs. Character ; using dotnet_rpg. For the life of me, I couldn’t figure it out. Automapper - how to map to constructor parameters instead of property setters. 1. You can get to the mapper using the overload of ResolveUsing that accepts a delegate with four parameters, the last of which is ResolutionContext that has a Mapper NOTE: Travis Illig has provided a hollistic answer to the question which I am marking as the answer as it answers the question in a broad and generic way. Map for the first time, AutoMapper will create the type map configuration and compile the mapping plan. It will be removed in 6. Which implies AutoMapper is not using AutoFac to resolve/create those instances From this one line of code in the AutoMapperProfile constructor I am getting the following compile time error: The type 'WebSite. AddProfile(new BLProfile()); // mapping between Business and Assuming that MyMappingProfile inherits from the AutoMapper. ; In version 4. (Parameter 'type')" AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and application layer. (Nitpicking: it should probably say "parameters" rather than "args". Closed keerthimaryala18 opened this issue Jun 6, I use this in the mapper profile. When you call Mapper. using AutoMapper ; using dotnet_rpg. 1), and it's giving me an exception: I'm thinking of having a static constructor initialize the my profile so that it will always be available – Andy. I'm trying to register my AutoMapper (version 5. I have configured AutoMapper in my Startup. ) I'm not sure this is the best way to inject dependency in profile class. Sometimes this method may have parameters, you can specify those parameters by passing the map_to_accessor_parameter option. AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and application layer. ; In the Convert method of your customer type converter, you can recover your parameter(s) from the Configure Automapper in ASP. Address -> Fortunately, AutoMapper provides a way to use constructor with parameters So we changed our Mapping Profile like below. Here is a quick example: public class Profile Instances A good way to organize your mapping configurations is with profiles. And then you let AutoMapper know in what assemblies are those I ran into this as well in AutoMapper 11. Here I AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and application layer. ***. Mapping a List using a Custom Resolver with Automapper. The view model has a SelectList property for a drop down in the view. Services. This method is used to map AutoMapper / AutoMapper Public. 2) If the binding was defined in a module, ensure that the module has been loaded into the kernel. CreateMap<Vendor, Provide constructor parameter to Automapper at time of Mapping. Register(IConfigurationProvider configurationProvider) at AutoMapper. You can't use dependency injection with DTOs (or you don't want to: keep your DTOs simple & stupid). AutomapperConstructorTest { class Program { static void Main(string[] args) { I somehow want the default value in DestClass to win. entities. Profile and referencing it in my ConfigureAutoMapper method of the Startup class This is how you create MapperConfiguration with profiles. Provide constructor parameter to Automapper at time of Mapping. Now that AutoMapper will perform a mapping from Foo to ignore, add a custom resolver, or modify the source/destination type For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters ===== Foo -> Bar (Destination member list) MyApp. 1 this code works properly but in 5 beta not I couldn't find a way to change the mapping expression outside the profile and nobody answered it. AutoMapper can map to destination constructors based on source members: public class Source {public int Value CreateMap < Source, SourceDto > ()); If the destination constructor parameter names don’t match, you can modify them at config time: You can configure which constructors are considered for the destination object: As I mentioned in a comment, your AutoFac code appears to be correct (except for the assembly scanning portion). String)'. Register AutoMapper in the Dependency Injection (DI) Container: Register AutoMapper in the Program. To perform a mapping, call Hi @jbogard "owner" come from the getter of the BranchCollection Property. The fix is to create a default constructor for your type. As of version 8. Is it okay to move the mapping code into a class which gets injected into my DI container or is there a better way? Provide constructor parameter to Automapper at time of Mapping. And, of course, add further using directives. Map<Calc>(). In my ASP. AM. ctor(System. Im trying to use automapper to map from one record to a new record and add a few defaults based on some logic. ; AutomapperProfile can have other Services injected to its constructor if needed. I'm developing an ASP. Foo -> MyApp It is not related to the nullable reference types. Map from a list of Source to a list of Destination async. CreateMap<SourceInterval, DestinationInterval None of the constructors found with 'Autofac. This injection is used for testing only. There is a NuGet package to be used with the default injection mechanism described here and used in this project. public static class MappingProfile { public static MapperConfiguration InitializeAutoMapper() { MapperConfiguration config = new MapperConfiguration(cfg => { cfg. public class AutoMapperConfiguration : Profile { private readonly I am currently migrating several mapping profiles from Automapper 4. 77. For a more robust AutoMapper configuration, I suggest that you use mapping profiles, instead of declaring the mapping directly in Global. 1 and AutoMapper. 0. NET project using . Assem honestly - I still dont have this working after at least 3 hours trying different things. Map to accessor parameter¶ When mapping from an object, AutoMapper will use the best available method or property to fetch the value of the property. DisplayIdResolver' cannot be used as type parameter 'TValueResolver' in the generic type or method 'IMemberConfigurationExpression<Developer, DeveloperDetailModel, However, it seemed that no matter what I did, the Destination. So while you still need injecting IMapper (but you need it anyway if you were using Map, so no difference), you don't need QueryableExtensions and ProjectTo extension method - you simply use the interface method (similar to Map): To use the below solution, you will need to inject your data context to the auto mapper profile class (via constructor parameter), and also, in the ConfigureServices, Then create the mapping in the automapper profile class constructor as: CreateMap<Employee, EmployeeSupervisorDto>() . 9k. Hi @jbogard "owner" come from the getter of the BranchCollection Property. ; mappingConfigurations . Issue The obtained User identity is always null. Commented Feb 4, 2023 at 16:57. Only tests can help with it. CreateMap<Order, OrderDto>()); The type on the left is the source type, and the type on the right is the destination type. mc. The example below shows the solution in which the runtime condition is applied to the expression using a parameter in the constructor of the profile. I. Profile public class Mappings : AutoMapper can map to destination constructors based on source members: public class Source {public int Value CreateMap < Source, SourceDto >()); If the destination constructor parameter names don’t match, you can modify them at config time: You can configure which constructors are considered for the destination object: I want to use IMemberValueResolver so I can reuse that resolver, therefore I can pass property instead of whole object. Instead, use the AutoMapper. User (Destination member list) Could anyone help make the following example work with Autofac? public class AutoMapperRegistry : Registry { public AutoMapperRegistry() { var profiles = from t in typeof (AutoMapperRegistry). 7k; Star 9. If your ORM exposes IQueryable s, you can use AutoMapper’s AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and application layer. Hot Network Questions By default AutoMapper uses the DateTimeInterface::RFC3339 format. String testSmtp' of constructor 'Void . (Parameter 'type') I tried to add such code, but without success: CreateMap<DateTimeOffset, DateTime>(). I need to ignore some members mapped inside these profiles at runtime for one of the mapper instances. I currently have the following mapping: Mapper. AutoMapper map Dictionary with the help of injected service. Configuration inside a profile only applies to maps inside the profile. My problem has been solved. However, for my scenario where I'm trying to pass an instance of IMappingEngine as a constructor parameter utilizing Ninject, I'm still not receiving initialized mappings. ConvertUsing(s => new Entity(s. repository = Without extra configuration, AutoMapper requires a flattened destination to match the source type’s naming structure. next will work: cfg. When you start thinking about using dependency injection (constructor injection in this case), you might want to rethink your The following is just one way of many, but this works quite good for me. ResolveUsing<DictionaryResolver>()); However, when you use a custom type resolver, this takes complete control of the mapping: there is I want to use IMemberValueResolver so I can reuse that resolver, therefore I can pass property instead of whole object. As of version 5, Configure() is obsolete. If you have a new() constraint on a generic type, that type must have a default constructor. Security. new Entity(int recordid); I added the following line: Mapper. Because the mapping from source to destination is convention-based, you will still need to test your configuration. However, I also wanted to document the specific solution to my question. For more complex scenarios where records have constructor parameters, AutoMapper’s ForCtorParam method comes into play. Profile I have some Automapper profiles, and I create two different mapper instances at runtime according to the situations. 0 To map Objects that need Constructor Parameters using Automapper you need to use the ConstructUsing Method while Creating the Map. I have found the ConstructUsing method, but that requires Although AutoMapper covers quite a few destination member mapping scenarios, there are the 1 to 5% of destination values that need a little help in resolving. MapFrom(k => "dummy")); AutoMapper Profiles and Unit Testing. UtcDateTime); Ignoring IValueResolver when mapping to constructor parameters #2549. Fre Doesn't allow parameters in automapper constructor – Martin Dawson. The example below shows the solution in which the runtime condition is applied to the expression using a parameter in the I am a newbie to the Automapper framework. The best I can say is that automapper does know 'know' how to construct one of the parameters to an IValueResolver instance. Here is a sample implementation, Step 3- Automapper profile dependency injection- IMapper into the module Goal: To inject IHttpContextAccessor as a dependency into autmapper profile 's constructor Why: I need to pass in the current user 's identity 's name as part of construction of one of my domain objects. e. However, every class has a constructor parameter. First of all, For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters Address -> AddressDto (Destination member list) Automapper. Can anyone advise me on this? Automapper Product Profile : We need to pass the assemblies as parameters to identify the AutoMapper profiles. You can use the mapper as it is a static Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company It is used as an IoC container where you register your mocks in the container then ask AutoMocker to construct an object of the required type and the mocks will be injected for the constructor parameters. 0. For your scenario, you need Constructor mapping by providing the constructor parameters via . What do I have so far? Startup. For example. String -> . The way I'm doing it "works" since I just pass the DomainModel to the constructor for the ViewModel, but since I'm using AutoMapper on some of my one-to-one ViewModels, I thought I'd try and learn how to do the mapping across all ViewModels. 2 Using Mapper. 70. But everything I have tried is failing or I can only create new instances of the parent object (using ConstructUsing), not map the one in the constructor. You need to be fairly careful of how you wire up the dependency resolver to AutoMapper, to be precise you must resolve the Profiles are one of the best way of organizing all your mapping configurations in one place. MapFrom(p 2) If the binding was defined in a module, ensure that the module has been loaded into the kernel. AddProfile(new WebMappingProfile()); //mapping between Web and Business layer objects cfg. NET Core – Getting Started; Define the Automapper Profile with service Dependency Injection. ProjectTo. Many times, this custom value resolution logic is domain logic that can go straight on our domain. In doing so ResolveUsing was consolidated with MapFrom. AutoMapper. 2, AutoMapper creates type maps on the fly (documented here):. So while you still need injecting IMapper (but you need it anyway if you were using Map, so no difference), you don't need QueryableExtensions and ProjectTo extension method - you simply use the interface method (similar to Map): AutoMapper relies on property setters to do its work, so if you have read-only properties, AutoMapper won't be of much use. CreateMap<PersonData, Person>() . 1 this code works properly but in 5 beta not However, when i execute the mapping process, i receive an exception (No parameterless constructor defined for this object. Instead, Automapper is mapping null back on to Value1 in Dest object after construction. 1 still applies, except that ResolveUsing has been renamed to MapFrom; the delegate signature remains the same. ConfigurationProvider can not assign value to ResolutionContext. public MappingProfile() { this. ctor(Action1 configure) at What you need, is to specify the constructor-parameter by name in your mapping profile like so public AToProfile() => CreateMap<BFrom, ATo>(). Configuration applied to the root configuration applies to all maps created. I think if Automapper will use Custom value resolvers are designed for overriding the mapping of a specific member, when AutoMapper is going to map the objects: Mapper. 2. 4) If you are using constructor arguments, ensure that the parameter name matches the constructors parameter name. Seal() at AutoMapper. I can't find a way to pass any information from my ApplicationService to the AutoMapper Profile, as IObjectMapper. You can’t inject dependencies into Profile classes, but you can do it in IMappingAction implementations. 0 and up. Load 7 more related questions Show fewer related questions . 0) Profile class into my Unity container (Unity version 4. Expiration was always null. Here you need to create a class that inherits from the class Profile then please add your configuration of mapping into the Constructor. I am passing in a interface to the constructor of my repository but i keep getting the following error: Type needs to have a constructor with 0 args or only optional args Parameter name: type I can get around it by creating a parameter-less constructor and hard coding the concrete implementation of my repo in there, but i want to inject it. Map functions, you may notice that the ORM will query all the fields of all the objects within a graph when AutoMapper is attempting to map the results to a destination type. NET MVC 2 (RC) project - I'm using AutoMapper to map between a Linq to Sql class (Media) and a view model (MediaVM). Starting with 8. DependencyInjection. OrderByDescending(ci => ci. Entities. Create Mapping Profiles: A mapping profile is a class inherited from Profile, where we define the mapping configurations between source and destination objects. EncryptionService' can be invoked with the available services and parameters: Cannot resolve parameter 'LMS. You need to implement an IValueConverter<TSourceMember, TDestMember> set it inside mapping configuration. How do I inject the AutoMapper Configuration in my Service model. I was under the impression that AutoMapper would be able to map the properties of Baz onto the constructor arguments of Foo, but apparently not. Controller: public class SchedulesController : Controller { private readonly IScheduleRepository repository; private readonly IMapper mapper; public SchedulesController(IScheduleRepository repository, IMapper mapper) { this. Then you just need to configure AutoMapper to use AutoMocker to construct it's services so the same behaviour is used for your resolvers. MapperConfiguration. And then you let AutoMapper know in what assemblies are those profiles defined by calling the IServiceCollection extension method // This teaches Ninject how to create automapper instances say if for instance // MyResolver has a constructor with a parameter that needs to be injected Bind Although AutoMapper covers quite a few destination member mapping scenarios, there are the 1 to 5% of destination values that need a little help in resolving.
