I am new to Automap, and I am trying to filter out the result. I want to know how to map nested dtos.
Post Entity:
public class Post
{
public Author? Author { get; set; }
[Required] [Key] public int Id { get; set; }
[Required] public string Title { get; set; }
[Required] public string Description { get; set; }
[Required] public string Body { get; set; }
}
PostRead: (dto)
public class PostRead
{
public DateTime Created { get; set; }
public string Title { get; set; }
public string Body { get; set; }
public string Description { get; set; }
// Author would work but I want only the AuthorRead data
public AuthorRead Author;
}
Author Entity
public class Author
{
[Key] [Required] public int Id { get; set; }
[Required] public string Name { get; set; }
public IEnumerable<Post> Posts { get; set; }
}
AuthorRead.cs (dto)
public class AuthorRead
{
public int Id { get; set; }
public string Name { get; set; }
}
Technically if I use Author Entity in PostRead, it works but it'll give the list of the posts the Author has, and i want only the information that is in the AuthorRead (so the API response doesn't send the list of posts of the Author itself).
how I can map the object of type Author to the type AuthorRead in the PostRead?
Errors:
AutoMapper.AutoMapperMappingException : Missing type map configuration or unsupported mapping.
Mapping types:
Object -> PostRead
System.Object -> OhMyBlogAPI.Models.PostRead
at lambda_method22(Closure , Object , PostRead , ResolutionContext )
at OhMyBlogAPI.Tests.AutomapTests.MockPost_MapsTo_PostRead() in
What I tried , and searching a lot.
CreateMap<Post, PostRead>()
.ForMember(m
=> m.Author, o
=> o.MapFrom<Author, AuthorRead>("Author"));
And profiles (each line represent relevant profiles content):
CreateMap<Post, PostRead>();
CreateMap<Author, AuthorRead>();
