MVC Dynamic Page Permissions Using Authorize Attribute?

Question

I\'m working on setting up my user permissions for my company\'s site, and we have several different roles and permissions that will have to be created. I have found some awesom

Answer 1

Implement the following custom authorise attribute.

public class CustomAuthorizeAttribute : AuthorizeAttribute
    {
        public CustomAuthorizeAttribute (params string[] roleKeys) 
        {
            var roles = new List();
            var allRoles = (NameValueCollection)ConfigurationManager.GetSection("CustomRoles");
            foreach(var roleKey in roleKeys) {
                roles.AddRange(allRoles[roleKey].Split(new []{','}));
            }

            Roles = string.Join(",", roles);
        }

        public override void OnAuthorization(AuthorizationContext filterContext)
        {
            base.OnAuthorization(filterContext);
            if (filterContext.Result is HttpUnauthorizedResult)
            {
                filterContext.Result = new RedirectResult("~/Error/AcessDenied");
            }
        }
    }

Then add the following to the web.config

and then, as an example

The on your controller or action or in the global filters (whichever you prefer :)) add the attribute

e.g.

[CustomAuthorize("UsersPagePermission")]
public class UserController : Controller

This will allow you to modify the web.config rather than code to change permissions.
