I've been trying to come up with a way to create a dynamic role based navigation solution for a project that I am working on.
The navigation should display only links that are relative to the users role, for example: an administrator will have links to view application statistics, manage customer accounts, ect... while a standard user would have links to manage their account, communicate with friends, ect..
I currently have a single partial view called Navigation with some basic conditional statements for role checking and a mix of markup for displaying the appropriate links. This works, but, I know it could quickly become unmanageable.
Navigation Partial View:
@if(User.IsInRole("Admin")) {
<li><a href="#">Statistics</a></li>
<li><a href="#">Accounts</a></li>
<li><a href="#">Dashboard</a></li>
}
@if(User.IsInRole("User")) {
<li><a href="#">Account</a></li>
<li><a href="#">Friends</a></li>
}
// code omitted
Is there a way to get this logic out of the view and let the Controller handle this?
SOLUTION
As suggested, I created a ChildAction called Menu and partial views for each role. Inside the action I do some role checking using some conditional statements and render the appropriate view.
This keeps the conditional statements out of the views which makes it a lot cleaner solution.
I'm sure there are a few things that could be done to tidy it up and I will continue trying to improve it.
Here is the solution I used.
In the layout view where I wanted the menu to appear I used this.
@Html.Action("Menu", "Navigation")
Then I created a controller called Navigation and added a single Action called Menu.
public class NavigationController : Controller
{
[ChildActionOnly]
public ActionResult Menu()
{
if (Roles.IsUserInRole("Administrator"))
{
return PartialView("_NavigationAdmin");
}
return PartialView("_NavigationPublic");
}
}
