ASP.Net Identity - Use custom Schema

Question

I am using MVC5 + Ef6 code first with ASP.Net Identity 1.0 and wish to have the tables created in a custom schema. i.e. a schema that is not the dbo schema.

Answer 1

Here is a late entry explaining what I did. Not sure if there is a better way, but this is the ONLY thing that worked for me.

To be fair, I have more than a single model in my context. Which is why this was better for me.

1. Generate the tables in a database ahead of time (while tables are still in 'dbo')
2. Execute add-migration on your project and let it create a migration
3. Change all the schemas within your migration code to the desired schema
4. Execute update-database to get those changes updated
5. Delete your original migration file (its' hash is useless to you)
6. Execute add-migration again and let it create a new migration
7. Update the OnModelCreating method of your configuration with the code below
8. Run your application and start registering users

NOTE:
You DO NOT want this.

// This globally assigned a new schema for me (for ALL models)
modelBuilder.HasDefaultSchema("security");

CONFIGURATION: OnModelCreating
This assigned a new schema for ONLY the mentioned tables

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder);

    modelBuilder.Entity<ApplicationUser>().ToTable("AspNetUsers", "security");
    modelBuilder.Entity<CustomRole>().ToTable("AspNetRoles", "security");
    modelBuilder.Entity<CustomUserClaim>().ToTable("AspNetUserClaims", "security");
    modelBuilder.Entity<CustomUserLogin>().ToTable("AspNetUserLogins", "security");
    modelBuilder.Entity<CustomUserRole>().ToTable("AspNetUserRoles", "security");
}

INITIAL MIGRATION LOOKS LIKE

public partial class Initial : DbMigration
{
    public override void Up()
    {
        CreateTable(
            "security.AspNetRoles",
            c => new
                {
                    Id = c.String(nullable: false, maxLength: 128),
                    Name = c.String(nullable: false, maxLength: 256),
                })
            .PrimaryKey(t => t.Id)
            .Index(t => t.Name, unique: true, name: "RoleNameIndex");

        CreateTable(
            "security.AspNetUserRoles",
            c => new
                {
                    UserId = c.String(nullable: false, maxLength: 128),
                    RoleId = c.String(nullable: false, maxLength: 128),
                })
            .PrimaryKey(t => new { t.UserId, t.RoleId })
            .ForeignKey("security.AspNetRoles", t => t.RoleId, cascadeDelete: true)
            .ForeignKey("security.AspNetUsers", t => t.UserId, cascadeDelete: true)
            .Index(t => t.UserId)
            .Index(t => t.RoleId);

        CreateTable(

                    LastName = c.String(nullable: false, maxLength: 250),
                    Email = c.String(maxLength: 256),
                    EmailConfirmed = c.Boolean(nullable: false),
                    PasswordHash = c.String(),

                    PhoneNumber = c.String(),
                    PhoneNumberConfirmed = c.Boolean(nullable: false),
                    TwoFactorEnabled = c.Boolean(nullable: false),
                    LockoutEndDateUtc = c.DateTime(),
                    LockoutEnabled = c.Boolean(nullable: false),
                    AccessFailedCount = c.Int(nullable: false),
                    UserName = c.String(nullable: false, maxLength: 256),
                })
            .PrimaryKey(t => t.Id)
            .Index(t => t.UserName, unique: true, name: "UserNameIndex");

        CreateTable(

            c => new
                {
                    Id = c.Int(nullable: false, identity: true),
                    UserId = c.String(nullable: false, maxLength: 128),
                    ClaimType = c.String(),
                    ClaimValue = c.String(),
                })
            .PrimaryKey(t => t.Id)
            .ForeignKey("security.AspNetUsers", t => t.UserId, cascadeDelete: true)
            .Index(t => t.UserId);

        CreateTable(

            c => new

Answer 2

public class MyDbContext : EntityDbContext<ApplicationUser>
{
    public DbSet<ApplicationUser> Users { get; set; }

    public MyDbContext() : base()
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        // You can globally assign schema here
        modelBuilder.HasDefaultSchema("schemaName");
    }
}

Answer 3

Sorry my english, i use google translator.

Some steps indicated by Prisioner ZERO are not necessary. The indications provided are based on the standard template with individual user accounts security.

First we must verify that our project is clean (insert commands in Package Management Console):

1. If you already have a database created with the default ASP.NET Identity schema, you have to delete the database with the following command (or delete directly in SQL Server) :

Drop-Database

2. If you have the default migration of the ASP.NET Identity template, execute the following command to remove it:

Remove-Migration

Now that our project is clean, we must modify the ApplicationDbContext class. We must overwrite the method OnModelCreating to indicate the scheme to which each of the tables generated by ASP.NET Identity will belong. The following link shows the entities used to map each of the tables as well as information about custom builders and options to change the data type of the primary key of each table: Identity Model Customization.

public class ApplicationDbContext : IdentityDbContext {
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options) { }

    protected override void OnModelCreating(ModelBuilder builder) {
        base.OnModelCreating(builder);
        builder.Entity<IdentityUser>().ToTable("AspNetUsers", "myschema");
        builder.Entity<IdentityRole>().ToTable("AspNetRoles", "myschema");
        builder.Entity<IdentityUserClaim>().ToTable("AspNetUserClaims", "myschema");
        builder.Entity<IdentityUserRole>().ToTable("AspNetUserRoles", "myschema");
        builder.Entity<IdentityUserLogin>().ToTable("AspNetUserLogins", "myschema");
        builder.Entity<IdentityRoleClaim>().ToTable("AspNetRoleClaims", "myschema");
        builder.Entity<IdentityUserToken>().ToTable("AspNetUserTokens", "myschema");
    }
}

Now we only have to generate our migration. For this in the Package Management Console enter the following command (optionally you can indicate the output route with the -OutputDir parameter):

Add-Migration InitialSchemaIdentity -OutputDir Data\Migrations

Then we apply the changes in our database with the command:

Update-Database
