Short way to check for controller/action in view

if params[:controller] == "posts" && params[:action] == "show"

Any shorter Railsy way to check for a certain controller/action-pair than the above?

Something like this?

if couple("posts#show")

Or even like this if multiple actions:

if couple("posts#show/index/edit")

There is a rails method for this, it's called current_page?(options)

Basically you can pass as argument what you like (controller, action, controller + action, url, etc)

For more information: http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-current_page-3F

You can always define a custom method in your ApplicationController. For simple cases, could be something like:

def couple?(route_path)
  controller, action = route_path.split('#')
  controller_name == controller && action_name == action
end
helper_method :couple?

This way, you are able to use that method in your controllers and views. If you don't really need to use it in your controllers, define it directly into ApplicationHelper.
