Forum: Ruby on Rails Request Controller Name in View?

Hi,

I was wondering if there were anyway to return the controller name in my
view.  Any help would be appreciated.  Thanks!

-Mario

params[:controller]

Views have a pointer to the controller, but I always setup a couple of
convenience variables in ApplicationController that additionally
follow Rick's authentication plugins notation (@current_user):

    before_filter :set_controller_and_action_names

    def set_controller_and_action_names
      @current_controller = controller_name
      @current_action     = action_name
    end

-- fxn

Um, why?

params[:controller] and params[:action] do exactly this!

you can get the controller name by

 @controller.controller_name

you can get the controller's name through
 @controller.controller_name in view

If you want to ask for the current controller name in a view the right
path in my opinion is to, ahem, ask the current controller for its name:

   <%= controller.controller_name %>

That's proper use of encapsulation. I just happen to prefer an
instance variable.

These actually deliver slightly different results.   My controller is 
one of a subest of controllers in an admin directory.

admin/products_controller.rb


params[:controller] returns "admin/products"
controller.controller_name return "products"

One may work better than the other, but it really depends on your need.

Thanks for the help!
