Question

I am trying click on a link to call this action.

<% link_to "popup", :action => 'user_logs_out', :controller => 'application'%>

In my application controller I have this action:

def user_logs_out
    gon.display_sign_out_popup = true
end

How can I call this action? It always shows template error. Since the action simply needs to set a boolean value, I don’t feel a need to have view file for it.

Answer 1

If you really want an action to render nothing, you can use render :nothing => true.

def user_logs_out
  display_sign_out_popup = true
  render :nothing => true
end

However, there is almost certainly no reason why you would want to do this.
