You can use a Request Filter, (I do not know if it is the best way) :
FilterProvider – defines the filter applied to each request. Resembles the way default ASP.NET MVC action filters work with the difference that it’s not an attribute. All FilterProvider objects are injected into the request pipeline and are applied to all requests (so you need to check if the current request is suitable for your filter at the beginning of an appropriate method).
From : http://www.szmyd.com.pl/blog/most-useful-orchard-extension-points
So you could implement something like this
public class Filter : FilterProvider, IAuthorizationFilter {
private readonly IAuthenticationService _authenticationService;
public Filter(IAuthenticationService authenticationService) {
_authenticationService = authenticationService;
}
public void OnAuthorization(AuthorizationContext filterContext) {
//If route is the restricted one
if (filterContext.HttpContext.Request.Url.AbsoluteUri.Contains("OrchardLocal/System/ManufacturedProducts")) {
//Get the logged user
IUser loggedUser = _authenticationService.GetAuthenticatedUser();
if (loggedUser == null)
return filterContext.Result = new HttpUnauthorizedResult();
//Get the Roles
var roles = loggedUser.As<IUserRoles>().Roles;
if (!roles.Contains("FactoryUser")) {
//User is not authorized
return filterContext.Result = new HttpUnauthorizedResult();
}
}
}
}
Note: Untested code!
EDIT: Also you could invert the logic and check if the logged user has the role 'FactoryUser' and restrict its access to every page except the one they should see.
