How to map from a flat entity to more than one DTO?

由 坚强是说给别人听的谎言 提交于 2019-12-04 20:10:25
I'm wishing to use AutoMapper in C# .NET Core to map from an already flattened entity to a nested set of DTO's. Also the DTO’s have a one to many relationship, which the flattened entity is hiding in structure. For example: public class Product { public int Id { get; set; } public string Name { get; set; } public int Price { get; set; } public int Weight { get; set; } } public class ProductDto { public string Name { get; set; } public IEnumerable<PriceDto> Prices { get; set; } } public class PriceDto { public int Price { get; set; } public int Weight { get; set; } } I'm aware of the ReverseMap

How do I debug AutoMapper.AutoMapperMappingException

由 北城余情 提交于 2019-12-04 19:46:41
问题 Is there some way to get some more detail from automapper when I get this exception: AutoMapper.AutoMapperMappingException Often it will tell me the 2 types of the mapping, but not which resolver or part of the mapping is failing. 回答1: Simple answer, is to call this method, preferably in your unit test. // ensure your configuration mappings are loaded first (bootstrapper) Mapper.AssertConfigurationIsValid(); see: http://docs.automapper.org/en/stable/Getting-started.html#how-do-i-test-my

Automapper and request specific resources

由 痴心易碎 提交于 2019-12-04 18:19:31
I'm considering automapper for an asp mvc intranet app I am writing. My controllers are currently created using Unity dependency injection, where each container gets dependencies unique to the request. I need to know if automapper can be made to use a request specific resource ICountryRepository to look up an object, like so.... domainObject.Country = CountryRepository.Load(viewModelObject.CountryCode); Couple of options here. One is to do a custom resolver: .ForMember(dest => dest.Country, opt => opt.ResolveUsing<CountryCodeResolver>()) Then your resolver would be (assuming CountryCode is a

Automapper - why use Mapper.Initialize?

由 偶尔善良 提交于 2019-12-04 16:11:09
问题 I wouldn't normally ask this kind of question on here, but unfortunately whilst AutoMapper seems to be a good mapping library, its documentation is woefully bad - there is no XML documentation for the library's methods, and the most official online documentation I could find was this, which is very brisk. If anyone has any better documentation, please let me know. That said, here's the question: why use Mapper.Initialize ? It doesn't seem to be required as you can just use Mapper.CreateMap

Automapper Mapping IEnumerable<SelectListItem> for Dropdown Menu

由 ＊爱你＆永不变心＊ 提交于 2019-12-04 16:05:02
Problem I am currently adding automapping to my MVC project and I am stuck. Right now I have a User model used to represent data in the database. I have to map that model to a EditUserModel which will be used when the Edit method is called. The EditUserModel has IEnumerable<SelectListItem> (for a dropdown menu) that I can't seem to figure out how to map. Attempted Solution As of right now I haven't tried to implement anything. I am unsure where the best place for the IEnumerable<SelectListItem> or where to populate it. Right now it is being populated in the Controller. User.cs public class

Automapper with base class and different configuration options for implementations

AutoMapper Exclude Fields

由 旧城冷巷雨未停 提交于 2019-12-04 15:27:52
问题 I'm trying to map one object to another but the object is quite complex. During development, I'd like the ability to either exclude a bunch of fields and get to them one by one or be able to specify to map only fields I want and increase that as each test succeeds. So: class string field1 string field2 string field3 Now I'd like to map field1 , test, fix and then move onto field2 then field3 . Is this possible? 回答1: .ForMember(dto => dto.field1, opt => opt.Ignore()); 来源： https://stackoverflow
