MVC 5种子用户和角色

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();
}
}
}

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 == "admin@admin.net"))
{
var user = new ApplicationUser
{
UserName = "admin@admin.net",
Email = "admin@admin.net",
PasswordHash = PasswordHash.HashPassword("123456")
};


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

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 = "shimmy@gmail.com",
EmailConfirmed = true,
PhoneNumber = "0123456789",
PhoneNumberConfirmed = true
};


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

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);
}

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" }
);




}
}
