C# MVC Do i have to use DB for Role Provider - asp.net-mvc

Question

I've been trying to use role provider but its been giving me headaches for a week.
All I am trying to do is allow a user to be able to see "Admin" Page if they are an admin (I've added Admin Coloumn in my database, to be 0 or 1)
Here is the code in my Controller for Login
if (user.Admin == 1)
{
addUserToRole(user.UserID, "Admin");
}
else
{
}
here is the method to add user to a role
public void addUserToRole(String user, String role)
{
if (!Roles.RoleExists(role))
Roles.CreateRole(role);
Roles.AddUserToRole(user, role);
}
for the admin controller, I want to enter this
[Authorize(role= "admin")]
Here is my webconfig
<profile defaultProvider="DefaultProfileProvider">
<providers>
<add name="DefaultProfileProvider" type="System.Web.Providers.DefaultProfileProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxx" connectionStringName="DefaultConnection" applicationName="/" />
</providers>
</profile>
<membership defaultProvider="DefaultMembershipProvider">
<providers>
<add name="DefaultMembershipProvider" type="System.Web.Providers.DefaultMembershipProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxx" connectionStringName="DefaultConnection" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" />
</providers>
</membership>
<roleManager defaultProvider="DefaultRoleProvider" enabled="true">
<providers>
<add name="DefaultRoleProvider" type="System.Web.Providers.DefaultRoleProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxx" connectionStringName="Database2Entities1" applicationName="/" />
</providers>
</roleManager>
my question is do I have to use database (meaning I had to add roles tables, etc) to use this role provider.
If yes is there another way I could implement this?

Answer 1

If you use SimpleMembership Provider the tables you will get automaticlly will be --> Your user table, Roles, UsersInRoles, Membership where in Roles you can add roles you wish and in UsersInRoles you can add users to role with this line:
assuming you already have the role "Admin" seed-ed into your database table for Roles
System.Web.Security.Roles.AddUsersToRole("username, "yourrolename");
the seeding of the role in the Roles table in the database is as you do it:
WebSecurity.InitializeDatabaseConnection("DefaultConnection",
"UserProfile", "UserId", "UserName", autoCreateTables: true);
var roles = (SimpleRoleProvider)Roles.Provider;
var membership = (SimpleMembershipProvider)Membership.Provider;
if (!roles.RoleExists("Admin"))
{
roles.CreateRole("Admin");
}
// you can do the seed of the role to user in the seed method too
if (membership.GetUser("user", false) == null)
{
membership.CreateUserAndAccount("user", "123456");
}
if (!roles.GetRolesForUser("user1").Contains("Admin"))
{
roles.AddUsersToRoles(new[] { "user" }, new[] { "Admin" });
}
you will also have to change the membership paragraph in your web config with this:
<roleManager enabled="true" defaultProvider="SimpleRoleProvider">
<providers>
<clear />
<add name="SimpleRoleProvider" type="WebMatrix.WebData.SimpleRoleProvider, WebMatrix.WebData" />
</providers>
</roleManager>
<membership defaultProvider="SimpleMembershipProvider">
<providers>
<clear />
<add name="SimpleMembershipProvider" type="WebMatrix.WebData.SimpleMembershipProvider, WebMatrix.WebData" />
</providers>
</membership>
but is not needed to be done every time you add user to role. Hope this helps.
