}In my article Drag And Drop Role Management with Asp.Net, MVC & jQuery[^] you can see how I check the role the current user has to see if they have the authority to run the action.
During the initialisation of the system you can add the roles into the database by calling a method in the global.asax Application_Start;
Obviously you would do this on the first run just to set things up. Later on you can either comment this out or do some logic checking to see if the roles or user accounts already exist.

protected void Application_Start()

AreaRegistration.RegisterAllAreas();

//Initialise the Database
//Database.SetInitializer(new DropCreateDatabaseAlways<TM470Project.DBContexts.DrillingDailyReportsDBContext>());
//Database.SetInitializer(new DropCreateDatabaseAlways<TM470Project.DBContexts.KPIDailyDBContext>());
//Initialise the user database Roles - Note:Set to true only during dev when cleaning up old roles being removed.
InitialiseRoles(false);
//Initialise the default SuperUser + Guest Account
InitialiseDefaultUsers();
//Use the new combined context for the intialiser
Database.SetInitializer(new DropCreateDatabaseIfModelChanges<TM470Project.DBContexts.CombinedDBContext>());
}
then the two methods are
then the two methods are
private void InitialiseRoles(Boolean DeleteExistingRoles)
{
if (DeleteExistingRoles)
{
//Delete All Existing Roles
//Get list of Roles
String[] oldRoles = Roles.GetAllRoles();
foreach (String role in oldRoles)
{
//Get all the usernames with Role
String[] users = Roles.GetUsersInRole(role);
//Remove all the users from Role
foreach (String user in users)
{
Roles.RemoveUserFromRole(user, role);

//Delete the Role

//Roles list to be used by application

//Check if role exists and add if not
foreach (String role in NewRoles)
{
if (!Roles.RoleExists(role))
{
Roles.CreateRole(role);
}
}
}
You can then add the default users onto the system by doing;

Membership.CreateUser("SuperUser", "ThePassword","SuperUser@the-email.net");

//Check the SuperUser account has all roles
String[] roles = Roles.GetAllRoles();
foreach (String role in roles)

{
Roles.AddUserToRole("SuperUser", role);
}
}
//Default Guest Account
user = Membership.GetUser("Guest");
if (user==null)
{
//Account does not exist
Membership.CreateUser("Guest", "guest-password", "guest@the-email.net");
}
//Add roles to Guest Account
String[] guestRoles = new String[] {"KPI-Daily-View","KPI-Losses-View","Drilling-Report-View"};
foreach (String role in guestRoles)
{
if (!(Roles.IsUserInRole("Guest", role)))
{
Roles.AddUserToRole("Guest", role);
}
}
}
Note: the code above is from my OU project that the drag and drop article was also based on, hence all those different roles for the different things the application was doing.
