In my ASP.NET MVC Application, I customized the Identity to use another table for storing the users' infos such as first name, last name and birthdate. Here's the association code:
public class ApplicationUser : IdentityUser
{
public virtual UserInfo Info { get; set; }
}
public class UserInfo
{
public int Id { get; set; }
public string FirstName { get; set;
public string LastName { get; set; }
public DateTime BirthDate { get; set; }
}
But how do you use the primary key of the ApplicationUser class as the primary key of UserInfo so that you know which user accounts the infos belong to?
The primary Key of ApplicationUser will be of a default type String, so first you will need to change your dependent class to also have a key of type string.
public class UserInfo
{
public string Id { get; set; }
public string FirstName { get; set;
public string LastName { get; set; }
public DateTime BirthDate { get; set; }
}
Then in your IdentityDbContext implementation you will need to create a mapping to create the 1:1 relationship you are after like so.
public class MyIdentityDbContext : IdentityDbContext
{
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<ApplicationUser>().HasRequired(x => x.Info).WithRequiredDependent();
base.OnModelCreating(modelBuilder);
}
}
and that should work

I have my ApplicationUser model defined like so:
public class ApplicationUser : IdentityUser
{
public virtual UserProfileInfo UserProfileInfo { get; set; }
}
With UserProfileInfo being an auxiliary table containing extra user data, defined as such:
public class UserProfileInfo
{
public int Id { get; set; }
public string SuperiorId { get; set; }
[ForeignKey("SuperiorId")]
public virtual ICollection<ApplicationUser> Superior { get; set; }
}
Each user has one or more people who are superior to them, in a business hierarchy. However, attempting to do a migration results in the following error:
The ForeignKeyAttribute on property 'Superior' on type 'Project.Models.UserProfileInfo' is not valid. The foreign key name 'SuperiorId' was not found on the dependent type 'Project.Models.ApplicationUser'.
How can I make a foreign key reference to ApplicationUser in my situation?
You need to do it the other way around, the ID is the foreignkey of the navigational property:
public class UserProfileInfo
{
public int Id { get; set; }
[ForeignKey("Superior")]
public string SuperiorId { get; set; }
public virtual ICollection<ApplicationUser> Superior { get; set; }
}
Question 1.
I have created a database in code-first.
[Column(TypeName="datetime2")]
public DateTime RegistDate { get; set; }
In this way, the table is not created.
modelBuilder.Entity<Test>().Property(f => f.RegistDate).HasColumnType("datetime2");
(In OnModelCreating method)
I can be resolved by using Fluent API.
To create a column format datetime2, is there a way only a Fluent API?
Question 2.
I have a domain model as follows.
User Entity Class
public class User
{
public Guid UserId { get; set; }
public string UserName { get; set; }
public string Password { get; set; }
public string UserEmail { get; set; }
public DateTime JoinDate { get; set; }
public DateTime LoginDate { get; set; }
public virtual ICollection<UsersInRole> UsersInRoles { get; set; }
}
Role Entity Class
public class Role
{
public Guid RoleId { get; set; }
public string RoleName { get; set; }
public DateTime CreateDate { get; set; }
public virtual ICollection<UsersInRole> UsersInRoles { get; set; }
}
UsersInRole Entity Class
public class UsersInRole
{
public Guid UserId { get; set; }
public Guid RoleId { get; set; }
public DateTime SetDate { get; set; }
[ForeignKey("UserId")]
public User User { get; set; }
[ForeignKey("RoleId")]
public Role Role { get; set; }
}
This build, the following error will occur
One or more validation errors were detected during model generation:
\tSystem.Data.Entity.Edm.EdmEntityType: : EntityType 'UsersInRole' has no key defined. Define the key for this EntityType.
\tSystem.Data.Entity.Edm.EdmEntitySet: EntityType: EntitySet 'UsersInRoles' is based on type 'UsersInRole' that has no keys defined.
I do not want to add another property Id.
Also, I can not use the [Key] UserId, to RoleId.
There are no other solutions?
I am a MVC newbie so go easy on me please.
I am getting two errors when I try to add a migration. They are as follows:
EntityType 'Icon' has no key defined. Define the key for this EntityType.
EntityType: EntitySet 'Icons' is based on type 'Icon' that has no keys defined.
I am including the Icon inside another model, like so:
public class Icon
{
public string IconName { get; set; }
public string IconColor { get; set; }
public int BackgroundXPos { get; set; }
public int BackgroundYPos { get; set; }
public string IconColorHover { get; set; }
public int BackgroundHoverXPos { get; set; }
public int BackgroundHoverYPos { get; set; }
}
public class GalleryThumbnail : CSSBoxModel
{
[DisplayName("Thumbnail Image Outline Color")]
public string ThumbnailImageOutlineColor { get; set; }
[DisplayName("Thumbnail Menu Font")]
public CSSFont ThumbnailMenuFont { get; set; }
[DisplayName("Thumbnail Icon Color")]
public Icon ThumbnailIconColor { get; set; }
}
How is this Address class below any different which is working:
public class Address
{
public String Adress1 { get; set; }
public String Adress2 { get; set; }
public String Adress3 { get; set; }
public String City { get; set; }
public String County { get; set; }
public String State { get; set; }
public String Zip { get; set; }
public String Country { get; set; }
}
[Table("UserProfile")] //Could be PP empolyee, Subscriber or Subscriber's customer
public class UserProfile
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
public string UserName { get; set; }
public bool? Gender { get; set; }
public Address Address { get; set; } //billing address
public Address ShipAddress { get; set; }
}
I did not add a key in either my Icon or Address class because I have no intention of storing specific data in my DB. They are merely to be used inside other classes. So wy is one neededing an ID and the other is not?
I have not created public DbSet Icons { get; set; } in my DB Context either.
Also can you tell me what it is called when you use a class inside another ( or instance of class inside a class as in these examples ) ?
Much appreciated!
Since the address entity has no key defined it the Entity Framework assumes it's a complex property, and your UserProfile table will be rendered with columns named Addres_Address1, Address_Address2, Address_Address3, Address_City, and so on...
Even though you haven't declared an EntitySetIcons DbSet on your context class, it's still being added implicitly because one of your other classes somewhere has an ICollection or IEnumerable property defined.
More info on Code Conventions here:
http://msdn.microsoft.com/en-us/data/jj679962.aspx
So, either decorate the collections as NotMapped like #Kamyar said or simply remove the references from any class already declared as a DbSet.
you can use [NotMapped] attribute in System.ComponentModel.DataAnnotations.Schema namespace in EntityFramework.dll:
using System.ComponentModel.DataAnnotations.Schema;
...
[NotMapped]
public Address Address { get; set; } //billing address
[NotMapped]
public Address ShipAddress { get; set; }
Regarding the naming, AFAIK these are called public properties as well.
I want to create large user table (advance User Profile) and save user's data in my database context. So, I don't want to use 2 DbContexts in my project. When users register to site, they data (UserName, Password etc.) stores my own User table. My classes are like this:
public class ModelBase
{
public int Id { get; set; }
public DateTime CreateDate { get; set; }
public DateTime LastUpdateDate { get; set; }
}
public class User : ModelBase
{
public string UserName { get; set; }
public string Password{ get; set; }
public string FullName { get; set; }
public string Email { get; set; }
public DateTime BirthDate { get; set; }
public string Specialty { get; set; }
}
public class News : ModelBase
{
public int UserId { get; set; }
public string Title { get; set; }
...
}
....
Context is so:
public class MyDBContext : DbContext
{
public MyDBContext()
{
Database.SetInitializer<MyDBContext>(new MyDBContextInitializer());
}
public DbSet<User> UserSet { get; set; }
public DbSet<News> NewsSet { get; set; }
public DbSet<Project> ProjectSet { get; set; }
public DbSet<Section> SectionSet { get; set; }
....
}
class MyDBContextInitializer : DropCreateDatabaseIfModelChanges<MyDBContext>
{
protected override void Seed(MyDBContext context)
{
base.Seed(context);
}
}
I replaced DbContext name with mine and changed connection name in default SimpleMembershipInitializer class like this:
....
Database.SetInitializer<MyDBContext>(null);
try
{
using (var context = new MyDBContext())
{
if (!context.Database.Exists())
{
// Create the SimpleMembership database without Entity Framework migration schema
((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
}
}
WebSecurity.InitializeDatabaseConnection("MyDBContextConnection", "User", "Id", "UserName", autoCreateTables: true);
....
Finally, I changed RegisterModel and WebSecurity.CreateUserAndAccount() suitable my User class. But, it does not work.
How can I use my own User table for register to site?
You can have Asp.net Membership and your complex classes connected together.
with this approach you will save so much time because asp.net membership is much more robust(you don't need to think about Role and User management) and sure you can make use of existing open source project like this and add it to your project with minimum effort of time.
Then your class will have structure like :
public class CustomUserDetail : ModelBase
{
public string UserName { get; set; } // what you really need is this to be unique for each user in you data base
// public string Password{ get; set; } handled by asp.net Membership
public string FullName { get; set; }
// public string Email { get; set; } handled by asp.net Membership
public DateTime BirthDate { get; set; }
public string Specialty { get; set; }
}
Then you can can add extension method to IPrincipal like :
public static CustomUserDetail CustomUserDetail (this IPrincipal principal)
{
var repository = new YourUserDetailRepository();
return repository.GetCurrentUserDetail();
}
and finnaly in your code easily use
<p> #User.CustomUserDetail.FullName </p>
I am getting this error in my MVC Application:
One or more validation errors were detected during model generation:
System.Data.Edm.EdmEntityType: : EntityType 'CustomerModel' has no key defined. Define the key for this EntityType.
System.Data.Edm.EdmEntitySet: EntityType: EntitySet �Customer� is based on type �CustomerModel� that has no keys defined.
My Customer Model looks like this:
public class CustomerModel
{
public string Name { get; set; }
public int CustomerID { get; set; }
public string Address { get; set; }
}
public class CustomerContext : DbContext
{
public DbSet<CustomerModel> Customer { get; set; }
}
By default, Entity Framework assumes a key property called Id exists in your model class. Your key property is called CustomerID, so Entity Framework can't find it.
Either change the name of your key property from CustomerID to Id, or decorate the CustomerID property with the Key attribute:
public class CustomerModel
{
public string Name { get; set; }
[Key]
public int CustomerID { get; set; }
public string Address { get; set; }
}
public class CustomerContext : DbContext
{
public DbSet<CustomerModel> Customer { get; set; }
}
