I have three related Entities in my blazor application Opportunity, AppUser and AssignedOpportunity, What I want to achieve is to map Opportunity and AppUser to a DTO Object ReturnAssignedOpportunityDTO which has similar fields as the entities, using AutoMapper, but am not sure how to do that, below are the entities
public partial class AssignedOpportunity
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int ID { get; set; }
[ForeignKey("OpportunityID")]
public string OpportunityID { get; set; }
public string Status { get; set; }
public Opportunity opportunity { get; set; }
[ForeignKey("UserID")]
public string UserID { get; set; }
public AppUser User { get; set; }
}
The opportunity
public partial class Opportunity
{
public Opportunity()
{
AssignedOpportunities= new HashSet<AssignedOpportunity>();
}
[Key]
public string ID { get; set; }
public string OpportunityName { get; set; }
public string Description { get; set; }
public string CreatedBy { get; set; }
public DateTime DateCreated { get; set; }
public double EstimatedValue { get; set; }
public string EmployeeNeed { get; set; }
public double RealValue { get; set; }
public string Location { get; set; }
public string ReasonStatus { get; set; }
public string Status { get; set; }
public virtual ICollection<AssignedOpportunity> AssignedOpportunities { get; set; }
}
AppUser Class
public partial class AppUser : IdentityUser
{
public AppUser()
{
AssignedOpportunities = new HashSet<AssignedOpportunity>();
}
public string FirstName { get; set; }
public string MiddleName { get; set; }
public string LastName { get; set; }
public string Gender { get; set; }
public string Street { get; set; }
public string City { get; set; }
public string LGA { get; set; }
public string State { get; set; }
public virtual ICollection<AssignedOpportunity> AssignedOpportunities { get; set; }
}
Here's the DTO Object I want to map to.
public class ReturnOpportunitiesDTO
{
public int ID { get; set; }
public string OpportunityID { get; set; }
public string OpportunityName { get; set; }
public double EstimatedValue { get; set; }
public string EmployeeNeed { get; set; }
public double RealValue { get; set; }
public string Location { get; set; }
public string UserID { get; set; }
public string UserFullName { get; set; }
public string Status { get; set; }
}
Here is my query to fetch the records
var result = await _context.AssignedOpportunities.Include(o => o.opportunity).
ThenInclude(a => a.User).
Where(a=>a.UserID==UserID.ToString()).ToListAsync();
return result;
This is how i usually setup Map Profile
public AssignArtisanProfile()
{
CreateMap<AssignedOpportunity, ReturnOpportunities>();
}
But since I want to map multiple entities, how do I include the other entity
Your scenario is just another example of flattening a complex object. You have properties in child objects, which you want to bring to the ground level, while still leveraging AutoMapper mapping capabilities. If only you could reuse other maps from app user and opportunity when mapping from assigned opportunity to the DTO... Well, there is a method called IncludeMembers() (see the docs) that exists precisely for such case. It allows you to reuse the configuration in the existing maps for the child types:
config.CreateMap<AssignedOpportunity, ReturnOpportunitiesDTO>()
.IncludeMembers(source => source.opportunity, source => source.User);
config.CreateMap<Opportunity, ReturnOpportunitiesDTO>();
config.CreateMap<AppUser, ReturnOpportunitiesDTO>()
.ForMember(
dest => dest.UserFullName,
options => options.MapFrom(source =>
string.Join(
" ",
source.FirstName,
source.MiddleName,
source.LastName)));
Usage:
var mappedDtos = mapper.Map<List<ReturnOpportunitiesDTO>>(assignedOpportuniesFromDatabase);
I am trying to map a model to a view, but I receive the error above when I am trying to display all my elements, since Automapper doesn't recognize the IEnumerable I think. I receive the error when I am trying to map FixedAssets to FixedAssetsView and FixedAssetsView to FixedAssets.
Here are the objects I am trying to map:
FixedAssets
public class FixedAssets : IEntityBase
{
public int ID { get; set; }
public string name { get; set; }
public virtual ICollection<Category> category { get; set; }
public string serialNo { get; set; }
public string provider { get; set;
public DateTime acquisitionDate { get; set; }
public DateTime warrantyEnd { get; set; }
public int inventoryNo { get; set; }
public string allocationStatus { get; set; }
public string owner { get; set; }
public DateTime allocationDate { get; set; }
public string serviceStatus { get; set; }
public string serviceResolution { get; set; }
public FixedAssets()
{
this.category = new HashSet<Category>();
}
}
FixedAssetsView
public class FixedAssetsView
{
public int ID { get; set; }
public string name { get; set; }
public virtual ICollection<CategoryView> category { get; set; }
public string serialNo { get; set; }
public string provider { get; set; }
public DateTime acquisitionDate { get; set; }
public DateTime warrantyEnd { get; set; }
public int inventoryNo { get; set; }
public string allocationStatus { get; set; }
public string owner { get; set; }
public DateTime allocationDate { get; set; }
public string serviceStatus { get; set; }
public string serviceResolution { get; set; }
}
Category
public class Category : IEntityBase
{
public int ID { get; set; }
public string categoryName { get; set; }
public virtual ICollection<FixedAssets> fixedasset { get; set; }
public Category()
{
this.fixedasset = new HashSet<FixedAssets>();
}
}
CategoryView
public class CategoryView
{
public int ID { get; set; }
public string categoryName { get; set; }
public virtual ICollection<FixedAssetsView> fixedasset { get; set; }
}
Automapper configuration
Mapper.Initialize(x =>
{
x.CreateMap<FixedAssets, FixedAssetsView>();
x.CreateMap<FixedAssetsView, FixedAssets>();
x.CreateMap<Category, CategoryView>();
x.CreateMap<CategoryView, Category>();
});
I believe you need a .ForMember in your Mapper initialization.
eg:
Mapper.CreateMap<IEnumerable<Source>, IEnumerable<Target>>()
.ForMember(f => f, mp => mp.MapFrom(
mfrom => mfrom.Select(s => AutoMapper.Mapper.Map(s, new Target())
)
);
My question is about how can i select some one-two column from those tables are included and at the end when i am selecting as list it is returning list of parent object but child are contain those column i mention to select?
var testq = _db.Homes
.Include(x => x.Indexs.Cities.Proviences.Regions)
.Include(x => x.Images)
.Select(x => new Homes {
Images = x.Images,
Address = x.Address,
Indexs.Cities.Proviences.Regions =
x.Indexs.Cities.Proviences.Regions.Name });
At the end I need to have list of home model (List) and just images and Address and region name have value and important just those are selected from database not all infromation in the tables. I am trying to make a query with better performance
Edit Add Models
public partial class dbContext : DbContext
{
public virtual DbSet<City> Cities { get; set; }
public virtual DbSet<Province> Provinces { get; set; }
public virtual DbSet<Region> Regions { get; set; }
public virtual DbSet<Index> Indexs { get; set; }
public virtual DbSet<Home> Homes { get; set; }
public virtual DbSet<Images> Imageses { get; set; }
}
public partial class Home
{
public Home()
{
Imageses = new HashSet<Images>();
}
[Key]
public int IDHome { get; set; }
[Required]
[StringLength(5)]
public string Cap { get; set; }
[Required]
[StringLength(10)]
public string Number { get; set; }
[Required]
[StringLength(50)]
public string Address { get; set; }
....
public virtual Index Indexs { get; set; }
public virtual ICollection<Images> Imageses { get; set; }
}
public class Index
{
public int ID { get; set; }
public int IDHome { get; set; }
....
public virtual City Cities { get; set; }
}
public partial class City
{

public int ID { get; set; }
public int IDProvincia { get; set; }
public decimal Latitudine { get; set; }
public decimal Longitudine { get; set; }
[Required]
[StringLength(100)]
public string Name { get; set; }

public virtual Province Provinces { get; set; }
}
public partial class Province

public int ID { get; set; }
public int IDRegione { get; set; }
[Required]
[StringLength(50)]
public string Name { get; set; }
[Required]
[StringLength(3)]
public string Init { get; set; }
...
public virtual Region Regions { get; set; }
}
public partial class Region
{
[Key]
public int ID { get; set; }
[Required]
[StringLength(50)]
public string Name { get; set; }
public DateTime DataInsert { get; set; }
...
}
public class Images
{
public int ID { get; set; }
public string Path { get; set; }
...
}
absolutely tables have more column just add here as example
you have to define a new type with the fields you need, or use an anonymous type.
.Select(x => new {
Images = x.Images,
Address = x.Address,
Indexs.Cities.Proviences.Regions =
x.Indexs.Cities.Proviences.Regions.Name });
I want to map one call to another, but I got exception all the time /An exception of type 'AutoMapper.AutoMapperMappingException' occurred in AutoMapper.dll but was not handled in user code/
Here are my Source Classes:
public class Snippet
{
public Snippet()
{
this.Labels = new HashSet<Label>();
this.Commennts = new HashSet<Comment>();
}
public int Id { get; set; }
[Required]
public string Title { get; set; }
public string Description { get; set; }
[Required]
public string Code { get; set; }
public int LanguageId { get; set; }
public string UserId { get; set; }
public DateTime CreatedOn { get; set; }
public ICollection<Label> Labels { get; set; }
public ICollection<Comment> Commennts { get; set; }
public virtual Language Language { get; set; }
public virtual ApplicationUser User { get; set; }
}
public class Label
{
public int Id { get; set; }
public string Name { get; set; }
public ICollection<Snippet> Snippets { get; set; }
}
Here are my Destination classes:
public class SnippetModels
{
public class Output
{
public int Id { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public DateTime CreatedOn { get; set; }
public string Code { get; set; }
public string LanguageName { get; set; }
public string UserUsername { get; set; }
public IEnumerable<LabelModels.Output> Labels { get; set; }
//TODO Comments Labels
}
}
public class LabelModels

public string Name { get; set; }
}
}
public class HomeViewModel
{
public IEnumerable<SnippetModels.Output> Snippets { get; set; }
public IEnumerable<LabelModels.Output> Labels { get; set; }
}
And finally I tied everything that pop up in my mind but no success:
Mapper.CreateMap<Snippy.Models.Label, LabelModels.Output>();
Mapper.CreateMap<IEnumerable<Snippy.Models.Label>, IEnumerable<LabelModels.Output>>();
Mapper.CreateMap<Snippy.Models.Snippet, SnippetModels.Output>()
.ForMember(dest => dest.Labels, opt => opt.MapFrom(src => src.Labels));
Mapper.CreateMap<IEnumerable<Snippy.Models.Snippet>, IEnumerable<SnippetModels.Output>>();
var newestSnippetsDatabase = this.Data.Snippets
.All()
.OrderByDescending(s => s.CreatedOn)
.Take(HomeVisibleItemsCount)
.Select(s => s)
.ToList();
var homeScreenView = new HomeViewModel
{
Snippets = Mapper.Map<IEnumerable<SnippetModels.Output>>(newestSnippetsDatabase)
};
Patrick, thanks for advice about correct question!
EDIT 1:
I have three table for many to many relationship. Like this:
GoodEntity:
public partial class GoodEntity
{
public GoodEntity()
{
this.GoodsAndProviders = new HashSet<GoodAndProviderEntity>();
}
public int id { get; set; }
public string name { get; set; }
public string description { get; set; }
public decimal cost { get; set; }
public Nullable<decimal> price { get; set; }
public virtual ICollection<GoodAndProviderEntity> GoodsAndProviders { get; set; }
}
ProviderEntity:
public partial class ProviderEntity
{
public ProviderEntity()
{
this.GoodsAndProviders = new HashSet<GoodAndProviderEntity>();
}
public int id { get; set; }
public string name { get; set; }
public string description { get; set; }
public string address { get; set; }
public string phone { get; set; }
public string email { get; set; }
public string url { get; set; }
public Nullable<int> rating { get; set; }
public virtual ICollection<GoodAndProviderEntity> GoodsAndProviders { get; set; }
}
Entity for many-to-many relationship:
public partial class GoodAndProviderEntity
{
public int id { get; set; }
public int good_id { get; set; }
public int provider_id { get; set; }
public virtual GoodEntity Goods { get; set; }
public virtual ProviderEntity Providers { get; set; }
}
GoodDTO:
public class GoodDTO
{
public int id { get; set; }
public string name { get; set; }
public string description { get; set; }
public decimal cost { get; set; }
public decimal? price { get; set; }
public IList<ProviderDTO> providers { get; set; }
}
ProviderDTO:
public class ProviderDTO
{
public int id { get; set; }
public string name { get; set; }
public string description { get; set; }
public string address { get; set; }
public string phone { get; set; }
public string email { get; set; }
public string url { get; set; }
public int? rating { get; set; }
}
This is code for creation maps:
Mapper.CreateMap<ProviderDTO, ProviderEntity>();
Mapper.CreateMap<ProviderEntity, ProviderDTO>();
Mapper.CreateMap<GoodEntity, GoodDTO>()
.ForMember(dto => dto.providers, opt => opt.MapFrom(x => x.GoodsAndProviders));
Mapper.CreateMap<GoodAndProviderEntity, ProviderDTO>();
And it works half. Automapper was mapped "goods" completely and was created list for all providers for this goods. But automapper don`t fill providers.
If I use Mapper.AssertConfigurationIsValid(), then:
Unmapped members were found. Review the types and members below. Add a custom mapping expression, ignore, add a custom resolver, or modify the source/destination type ======================================================= ProviderDTO -> ProviderEntity (Destination member list) Core.DTO.ProviderDTO -> DAL.EF.Entities.ProviderEntity (Destination member list) Unmapped properties: GoodsAndProviders ============================================================== GoodAndProviderEntity -> ProviderDTO (Destination member list) DAL.EF.Entities.GoodAndProviderEntity -> Core.DTO.ProviderDTO (Destination member list)
How to create mapping for many-to-many relationship?
Regards, Anton
With your current code you're trying to map the GoodAndProviderEntity into ProviderDTO.
Mapper.CreateMap<GoodEntity, GoodDTO>()
.ForMember(dto => dto.providers, opt => opt.MapFrom(x => x.GoodsAndProviders));
What you want to do, is to map ProviderEntity into ProviderDTO, so all you have to do is select the Providers from GoodsAndProviders as a list:
Mapper.CreateMap<GoodEntity, GoodDTO>()
.ForMember(dto => dto.providers, opt => opt.MapFrom(x => x.GoodsAndProviders.Select(y => y.Providers).ToList()));
