Hi.
I want just map entity to dto but profile props map to the dto.
Now what can i do for the following problem?
public abstract class DtoProfile<TEntity, TDto> : Profile, IProfile
{
public DtoProfile()
{
var profile = CreateMap<TEntity, TDto>();
CustomMapping(profile);
}
public virtual void CustomMapping(IMappingExpression<TEntity, TDto> mapping)
{
}
}
public class UserDto : DtoProfile<Users,UserDto>
{
public int Id { get; set; }
public string FullName { get; set; }
public string NationalCode { get; set; }
public DateTime CreatedDate { get; set; }
}
You're doing this in a wrong way. Mapping Profiles should be for mapping, and not to be inherited from the Dto itself.
You're inherting from Profile in DtoProfile, and these properties are defined in Profile, so they will be there. And as the name of class, it's for mapping profile, and shouldn't be used for Dto.
You should have two classes, one is UserDto where you add all the properties you need to map, and the other is UserDtoProfile which inherits from DtoProfile<User, UserDto> and apply your mappings.

I would like to map the following hierarchy of entities to the TestViewModel class. I have TestViewModel class with the same member names and perhaps I will add more members to the view model. I am using AutoMapper.
public class TestProfile : Profile
{
public TestProfile ()
{
CreateMap ??????
}
}
public class Test
{
public List<Test1> Tests1 { get; set; }
public int TestId { get; set; }
}
public class Test1
{
public int Test1Id { get; set; }
public string Name { get; set; }
public List<Document> Documents { get; set; }
}
public class Document
{
public int DocumentId { get; set; }
public DateTimeOffset? ChangeDate { get; set; }
public List<Payload> Payloads { get; set; }
}
public class Payload
{
public string PayloadName { get; set; }
}
You didn't tell us what your TestViewModel class looks like, and whether you also have DocumentViewModel, PayloadViewModel, etc. Typically if you are mapping to a another set of classes that have the same naming and structure, like a set of ViewModels, you will want to have a configuration like this:
public class TestProfile : Profile
{
public TestProfile()
{
CreateMap<Test, TestViewModel>();
CreateMap<Test1, Test1ViewModel>();
CreateMap<Document, DocumentViewModel>();
CreateMap<Payload, PayloadViewModel>();
}
}
This will map all like-named properties between the two sets of classes. If your TestViewModel shares the same child entities, then you only need the first line.
Forgive me if this question has been answered somewhere, I have been having a hard time finding a solution for this problem.
I am trying to set up EF Code First on an MVC4 Project. I have a User and Customer that both inherit from Person. I then have a Template object that has a Many-to-Many relationship with Customer and a One-to-Many relationship with User. Here is how I have it set up:
MODELS
public class Person
{
[Key]
public int PersonID { get; set; }
public string LastName { get; set; }
public string FirstName { get; set; }
public string FullName
{
get
{
return String.Format("{0} {1}", FirstName, LastName);
}
}
public string Email { get; set; }
public virtual List<Template> Templates { get; set; }
}
public class User : Person
{
....
}
public class Customer : Person
{
....
}
public class Template
{
public int TemplateId { get; set; }
public string TemplateName { get; set; }
public virtual List<Customer> Customers { get; set; }
[ForeignKey("User")]
public int UserId { get; set; }
public virtual User User { get; set; }
}
CONTEXT
public class ProjectContext : DbContext
{
public ProjectContext()
: base("name=ProjectDB")
{
}
public DbSet<Template> Templates { get; set; }
public DbSet<User> Users { get; set; }
public DbSet<Customer> Customers { get; set; }
public DbSet<Person> People { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions
.Remove<PluralizingTableNameConvention>();
modelBuilder.Entity<Template>()
.HasMany(x => x.Customers)
.WithMany(x => x.Templates)
.Map(x => x.MapLeftKey("TemplateId")
.MapRightKey("PersonId")
.ToTable("TemplateCustomer")
);
}
}
If I remove the Person DBSet out of the context this works fine but sets up TPT inheritance. I would like to use TPH inheritance, but when I enable migrations with the Person DBSet in the context it chokes:
NavigationProperty 'Templates' is not valid. Type 'MvcProject.Models.Customer' of FromRole 'Template_Customers_Target' in AssociationType 'MvcProject.Models.Template_Customers' must exactly match with the type 'MvcProject.Models.Person' on which this NavigationProperty is declared on.
Where am I going wrong here?
You cannot inherit navigation properties from a base entity. They always must be declared in the class the other end of the relationship is refering to.
Template.Customers is refering to Customer (not to Person), hence the inverse navigation property Templates must be declared in Customer (not in Person)
Template.User is refering to User (not to Person), hence the inverse navigation property Templates must be declared in User (not in Person)
So, basically you must move the Templates collection from Person into both derived classes:
public class Person
{
// no Templates collection here
}
public class User : Person
{
//...
public virtual List<Template> Templates { get; set; }
}
public class Customer : Person
{
//...
public virtual List<Template> Templates { get; set; }
}
Then you can define the two relationships with Fluent API like so:
modelBuilder.Entity<Template>()
.HasMany(t => t.Customers)
.WithMany(c => c.Templates) // = Customer.Templates
.Map(x => x.MapLeftKey("TemplateId")
.MapRightKey("PersonId")
.ToTable("TemplateCustomer"));
modelBuilder.Entity<Template>()
.HasRequired(t => t.User)
.WithMany(u => u.Templates) // = User.Templates
.HasForeignKey(t => t.UserId);
Change your HasMany selector to People:
modelBuilder.Entity<Template>()
.HasMany(x => x.People) // here
.WithMany(x => x.Templates)
.Map(x => x.MapLeftKey("TemplateId")
.MapRightKey("PersonId")
.ToTable("TemplateCustomer")
);
My class:
[PersistClass]
public class ExternalAccount
{
public virtual AccountType AccountType { get; set; }
public virtual int Id { get; private set; }
public virtual User User { get; set; }
public virtual Dictionary<string, string> Parameters { get; set; }
public ExternalAccount()
{
Parameters = new Dictionary<string, string>();
}
}
The Dictionary is not getting mapped. I understand that automapping doesn't work by default with Dictionaries, how do I configure the mapping? All Parameters is is a list of key/value pairs - so I would expect them to be stored in a table with a foreign key to the externalaccount table. I know I can do this with another class - but it makes access to the parameters in the class more difficult - I'd rather have to configure the complexity once.
Please bear in mind I am new Fluent and to nHibernate.
Thanks
Using a simple class relationship such as the following:
public class Foo {
public virtual IDictionary<string, Bar> Bars { get; set; }
}
public class Bar {
public virtual string Type { get; set; }
public virtual int Value { get; set; }
}
You can map this with Fluent NHibernate in this way:
mapping.HasMany(x => x.Bars)
.AsMap(x => x.Type);
Where Bar.Type is used as the index field into the dictionary.

I have the following situation with fluent nhibernate:
public class Stuff
{
public Stuff()
{
Entities = new List<Entity>();
}
public virtual int Id { get; set; }
public virtual IList<Entity> Entities { get; set; }
}
public abstract class Entity
{
public virtual int Id { get; set; }
public virtual string Type { get; set; }
public virtual Stuff Stuff { get; set; }
}
public class Person : Entity
{
public virtual string FirstName { get; set; }
public virtual string LastName { get; set; }
}
public class Animal : Entity
{
public virtual string Species { get; set; }
}
And then, i have the following code to use automap and generate these mappings:
var sessionFactory =
Fluently.Configure().Database(persistenceConfigurer).Mappings(
m =>
m.AutoMappings.Add(
AutoMap.Source(new Types(typeof(Entity), typeof(Person), typeof(Animal), typeof(Stuff))))
.ExportTo(#"e:\")).ExposeConfiguration(BuildSchema).BuildSessionFactory();
however, what's happening is that i get the following exception:
---> NHibernate.MappingException: Association references unmapped class: ConsoleApplication1.Models.Entity
if i make the entity class non abstract this works, however, i'd like to avoid having that table in the database but still maintain the hierarchy concept with the re
You need to add your auto mappings like this
AutoMap.AssemblyOf<Entity>(yourConfiguration).IgnoreBase<Entity>();
Not only will this ignore your Entity base class but you don't need to add each entity manually so long as each model inherits from Entity.
How should the following mapping configuration be solved?
public abstract class RepositoryEntity
{
public virtual int Id { get; set; }
}
public class Descriptor : RepositoryEntity
{
public virtual String Name { get; set; }
public virtual DateTime Timestamp { get; set; }
}
public class Proxy<TDescriptor> : RepositoryEntity
{
public virtual TDescriptor Descriptor { get; set; }
public virtual Byte[] SerializedValue { get; set; }
};
public class TestUnit : Proxy<Descriptor>
{
};
I receive problems when testing the TestUnit mapping - it says it's impossible to map the item with generic parameters. This happens if I attempt to map every class from the specified before.
If I attempt to map everything, except Proxy<T>, then I receive that there is no persister for the 'TestUnit'.
If I stop inheriting TestUnit from Proxy<Descriptor>, the mapping test works fine.
Does Fluent NHibernate have possibility to automap types inherited from some concrete Class<T> template? Could you help me with mapping these entities?
I used a combination of Fluent and Auto mappings.
Fluent mappings should be used for generics.
Configuration = Fluently.Configure()
.Database(SQLiteConfiguration.Standard.ShowSql().InMemory)
.Mappings(x =>
{
x.FluentMappings.AddFromAssemblyOf<RepositoryEntity>();
x.AutoMappings.Add(autoPersistenceModel);
});
