2.2: Identity Models Setup

Identity Model

1. In the ElevenNote.Data assembly, open the IdentityModels.cs file. Please note that we will be adding a lot of code in the next few steps. (2.2a-IdentityModelsScreenshot.md) Refer to this screenshot to see it all in context:

   

You will have an error on <Note> until the beginning of part 3, don't worry about it for now.

1. Look for the ApplicationDbContext function.

2. Underneath the function, but still inside the namespace, create the following IdentityUserLoginConfiguration class and method. This code will go right above the closing curly brace for the file:

    public class IdentityUserLoginConfiguration : EntityTypeConfiguration<IdentityUserLogin>
    {
        public IdentityUserLoginConfiguration()
        {
            HasKey(iul => iul.UserId);
        }
    }

} //<----Closing curly brace of file

1. CTRL . to bring in the using statement needed: using System.Data.Entity.ModelConfiguration;

2. Now create an IdentityUserRoleConfiguration class underneath the class you just created

    public class IdentityUserRoleConfiguration : EntityTypeConfiguration<IdentityUserRole>
    {

    }
}//<----Closing curly brace of file

1. In this class, add the following method

    public class IdentityUserRoleConfiguration : EntityTypeConfiguration<IdentityUserRole>
    {
        public IdentityUserRoleConfiguration()
        {
            HasKey(iur => iur.UserId);
        }
    }
}//<----Closing curly brace of file

1. Go back up under the Create() method that is within the ApplicationDbContext class

2. Underneath the Create() method, but still within the ApplicationDbContext class, add a Notes property

        public static ApplicationDbContext Create()
        {
            return new ApplicationDbContext();
        }
   
        public DbSet<Note> Notes { get; set; } //<--- Add this
   
    }

   • You will have an error on <Note> until the beginning of part 3, don't worry about it for now.

3. Directly underneath the Notes property, but still within the ApplicationDbContext class, type override and then a space.

4. Auto-complete should provide you with choices, choose OnModelCreating and hit enter.

5. Delete the base.OnModelCreating(modelBuilder); and replace it with the following:

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder
            .Conventions
            .Remove<PluralizingTableNameConvention>();

        modelBuilder
            .Configurations
            .Add(new IdentityUserLoginConfiguration())
            .Add(new IdentityUserRoleConfiguration());
    }
}

1. CTRL . to bring in the using statement needed

2. 

Notes:

Here is all of the code we have added for context:

IdentityModels.cs

Next, we'll create the Note entity for our database.
