Initializing RoleManager in ASP.NET Identity with Custom Roles

Question

I changed the primary key for the user database from string to int using the tutorial here, but I\'m having difficulty initializing the Role Manager. It used to be initiali

Answer 1

Your ApplicationRoleManager may look like this. because you have to inherit from your customRole class instead of IdentityRole.

public class ApplicationRoleManager : RoleManager<CustomRole, int>
{
    public ApplicationRoleManager(IRoleStore<CustomRole, int> roleStore)
        : base(roleStore)
    {
    }

    public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
    {
        return new ApplicationRoleManager(new RoleStore<CustomRole, int, CustomUserRole>(context.Get<ApplicationDbContext>()));
    }
}

Then add following code to Startup.Auth.cs class if not currently exists.

app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);

Then you create and manage roles.

    var roleManager = HttpContext.GetOwinContext().Get<ApplicationRoleManager>();

    const string roleName = "Admin";

    //Create Role Admin if it does not exist
    var role = roleManager.FindByName(roleName);
    if (role == null)
    {
        role = new CustomRole();
        role.Id = 1; // this will be integer
        role.Name = roleName;

        var roleresult = roleManager.Create(role);
    }

Hope this helps.

From your question i cannot determine if you are using the same frameworks (MVC & EF).

Recently i have created an MVC + EF solution using custom ApplicationUsers & IdentityRoles. ApplicationUser is deriving from "Microsoft.AspNet.Identity.EntityFramework.IdentityUser". ApplicationRoles are implemented without changes.

I have the following class:

// Configure the used in the application. RoleManager is defined in the ASP.NET Identity core assembly
    public class ApplicationRoleManager : RoleManager<IdentityRole>
    {
        public ApplicationRoleManager(IRoleStore<IdentityRole, string> roleStore)
            : base(roleStore)
        {
        }

        public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
        {
            return new ApplicationRoleManager(new RoleStore<IdentityRole>(context.Get<ApplicationDbContext>()));
        }
    }

within configuration.cs (migrations)==> on 'update-database' this will be executed

    var roleStore = new RoleStore<IdentityRole>(context);
    var roleManager = new RoleManager<IdentityRole>(roleStore);
    var applicationRoleAdministrator = new IdentityRole("Administrator");
    if (!roleManager.RoleExists(applicationRoleAdministrator.Name))
    {
       roleManager.Create(applicationRoleAdministrator);
    }
// do some logic to find your applicationUserAdministrator
var applicationUserAdministrator = userManager.FindByName("Administrator");
userManager.AddToRole(applicationUserAdministrator.Id, applicationRoleAdministrator.Name);

withing startup.auth.cs the linkage towards the RoleManager:

app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);

Hope this helps.

    var roleManager = new RoleManager<CustomRole,int>(new RoleStore<CustomRole,int,CustomUserRole>(context));
    var UserManager = new UserManager<ApplicationUser,int>(new UserStore<ApplicationUser,CustomRole,int,CustomUserLogin,CustomUserRole,CustomUserClaim>(context));

   // In Startup iam creating first Admin Role and creating a default Admin User     
    if (!roleManager.RoleExists("Admin")){
    //first we create Admin rool   
        var role = new CustomRole();
        role.Name = "Admin";
        roleManager.Create(role);
    }

    ////Here we create a Admin super user who will maintain the website     
    if (UserManager.FindByName("Admin") == null){
        var user = new ApplicationUser() { UserName = "Admin" };
        string userPWD = "adminadmin";
        var chkUser = UserManager.Create(user, userPWD);
        if (chkUser.Succeeded){
            var result1 = UserManager.AddToRole(user.Id, "Admin")
            ;
        }
    }
