MVC 5 Seed Users and Roles

I have been playing about with the new MVC 5, I have a few models, controller and views setup using code first migrations.

My question is how do I seed users and roles? I currently seed some reference data in my Seed method in Configuration.cs. But it looks to me that the user and roles tables are not created until something first hits the AccountController.

I currently have two connection strings so I can separate my data from my authentication into different databases.

How can I get the user, roles, etc tables populate along with my others? And not when the account controller is hit?

Here is example of usual Seed approach:

protected override void Seed(SecurityModule.DataContexts.IdentityDb context)
{
    if (!context.Roles.Any(r => r.Name == "AppAdmin"))
    {
        var store = new RoleStore<IdentityRole>(context);
        var manager = new RoleManager<IdentityRole>(store);
        var role = new IdentityRole { Name = "AppAdmin" };

        manager.Create(role);
    }

    if (!context.Users.Any(u => u.UserName == "founder"))
    {
        var store = new UserStore<ApplicationUser>(context);
        var manager = new UserManager<ApplicationUser>(store);
        var user = new ApplicationUser {UserName = "founder"};

        manager.Create(user, "ChangeItAsap!");
        manager.AddToRole(user.Id, "AppAdmin");
    }
}

I used package-manager "update-database". DB and all tables were created and seeded with data.

It's a small addition, but to anyone having the "UserId not found." message when trying to seed: (Tom Regan had this question in the comments, and I was stuck on it myself for a while)

This means that the manager.Create(user, "ChangeItAsap!") was not successful. This might have a different reason, but for me it was because my password was not succeeding its validation.

I had a custom passwordvalidator, which was not being called when seeding the database, so the validation rules i was used to (minlength 4 instead of default 6) did not apply. Make sure your password (and all other fields for that matter) is passing validation.

This is my method base on Valin answer, I have added roles in db and added password for user. This code is placed in Seed() method in Migrations>Configurations.cs.

// role (Const.getRoles() return string[] whit all roles)

    var RoleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));
    for (int i = 0; i < Const.getRoles().Length; i++)
    {
        if (RoleManager.RoleExists(Const.getRoles()[i]) == false)
        {
            RoleManager.Create(new IdentityRole(Const.getRoles()[i]));
        }
    }

// user

    var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));
    var PasswordHash = new PasswordHasher();
    if (!context.Users.Any(u => u.UserName == "[email protected]"))
    {
        var user = new ApplicationUser
        {
             UserName = "[email protected]",
             Email = "[email protected]",
             PasswordHash = PasswordHash.HashPassword("123456")
         };

         UserManager.Create(user);
         UserManager.AddToRole(user.Id, Const.getRoles()[0]);
    }

Here i have an very easy,clean and smooth solution.

 protected override void Seed(UserContext context)
    { 
        //Step 1 Create the user.
        var passwordHasher = new PasswordHasher();
        var user = new IdentityUser("Administrator");
        user.PasswordHash = passwordHasher.HashPassword("Admin12345");
        user.SecurityStamp = Guid.NewGuid().ToString();

        //Step 2 Create and add the new Role.
        var roleToChoose = new IdentityRole("Admin");
        context.Roles.Add(roleToChoose);

        //Step 3 Create a role for a user
        var role = new IdentityUserRole();
        role.RoleId = roleToChoose.Id;
        role.UserId = user.Id;

         //Step 4 Add the role row and add the user to DB)
        user.Roles.Add(role);
        context.Users.Add(user);
    }

protected override void Seed(ApplicationDbContext context)
{
  SeedAsync(context).GetAwaiter().GetResult();
}

private async Task SeedAsync(ApplicationDbContext context)
{
  var userManager = new ApplicationUserManager(new UserStore<ApplicationUser, ApplicationRole, int, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>(context));
  var roleManager = new ApplicationRoleManager(new RoleStore<ApplicationRole, int, ApplicationUserRole>(context));

  if (!roleManager.Roles.Any())
  {
    await roleManager.CreateAsync(new ApplicationRole { Name = ApplicationRole.AdminRoleName });
    await roleManager.CreateAsync(new ApplicationRole { Name = ApplicationRole.AffiliateRoleName });
  }

  if (!userManager.Users.Any(u => u.UserName == "shimmy"))
  {
    var user = new ApplicationUser
    {
      UserName = "shimmy",
      Email = "[email protected]",
      EmailConfirmed = true,
      PhoneNumber = "0123456789",
      PhoneNumberConfirmed = true
    };

    await userManager.CreateAsync(user, "****");
    await userManager.AddToRoleAsync(user.Id, ApplicationRole.AdminRoleName);
  }
}

Looks like they changes the way authentication works in MVC5, changed my Global.asax.cs to the following did the trick!

using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;

using System.Threading.Tasks;
using MvcAuth.Models;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;
using System.Threading;
using Microsoft.AspNet.Identity.EntityFramework;

namespace MvcAuth
{
    public class MvcApplication : System.Web.HttpApplication
    {
        async Task<bool> AddRoleAndUser()
        {
            AuthenticationIdentityManager IdentityManager = new AuthenticationIdentityManager(
                new IdentityStore(new ApplicationDbContext()));

            var role = new Role("Role1");
            IdentityResult result = await IdentityManager.Roles.CreateRoleAsync(role, CancellationToken.None);
            if (result.Success == false)
                return false;

            var user = new ApplicationUser() { UserName = "user1" };
            result = await IdentityManager.Users.CreateLocalUserAsync(user, "Password1");
            if (result.Success == false)
                return false;

            result = await IdentityManager.Roles.AddUserToRoleAsync(user.Id, role.Id, CancellationToken.None);
            return result.Success;
        }

        protected async void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            bool x = await AddRoleAndUser();
        }
    }
}

write this code in your Migration Configuration.

> note: Use ApplicationDbContext in Configuration Class.

    internal sealed class Configuration : DbMigrationsConfiguration<ApplicationDbContext>
{
    public Configuration()
    {
        AutomaticMigrationsEnabled = true;
        AutomaticMigrationDataLossAllowed = false;
    }

    protected override void Seed(ApplicationDbContext context)
    {
        //  This method will be called after migrating to the latest version.

        //  You can use the DbSet<T>.AddOrUpdate() helper extension method 
        //  to avoid creating duplicate seed data.
                   context.Roles.AddOrUpdate(p =>
            p.Id,
                new IdentityRole { Name = "Admins"},
                new IdentityRole { Name = "PowerUsers" },
                new IdentityRole { Name = "Users" },
                new IdentityRole { Name = "Anonymous" }
            );


    }
}
