在命名空间控制器上检查CanCan中的功能

Question

Given the following example from the CanCan wiki,

https://github.com/ryanb/cancan/wiki/Admin-Namespace

How would I do a can? check within a view for the namespaced article controller.
For the purpose of this, imagine the ability.rb file states the current user.role is able to view an article, and the admin_ability.rb states the user can create an article

<% if can? :read, Articles %>
  I can view an article
<% end %>


<% if can? :create, Articles %>
  I can create an article
<% end %>

I don't know how to get the latter to work. It would be neat if I could specify the namespace on it perhaps such as

<% if admin::can? :create, Articles %>

But I am not sure what the syntax would be if that were possible.

Answer 1

I don't think Marc's suggestion will work. Checkout this wiki from Ryan. https://github.com/ryanb/cancan/wiki/Admin-Namespace

Answer 2

你有没有尝试过：

<% if can? :create, Admin::Articles %>
