Question

I create an admin page by using activeadmin gem http://activeadmin.info/
I use cancan to authorize the privilege for 2 kind of user, user manage and book manage user.

My question is: How I hide the resource User when a book manage user log in to admin page?

I tried something like that but it didn’t work

 menu false  if can? :manage, BookHeader 

or

 menu false  if authorize! :manage, BookHeader

Thanks for your help!

Answer 1

You have to use proc for build menu dynamicly

Examples

dynamic label

menu :label => proc{current_admin_user.admin? ? "Accounts" : "My Account"}

Display/Hide

 menu :if => proc{ can?(:manage, BookHeader ) }
