How to dynamically transmit params in link_to ?

I need to use part of my application in iframe on another page. So I need to remove layout on these pages.

I added to ApplicationController

layout :current_layout
def current_layout
  if params[:layout] == false.to_s
    false
  else
    'main'
  end
end

This works until user click on any link in navigation. So I need to add to every link_to in this part of application something like: 

link_to 'store', store_path(params.merge({layout: params[:layout]})

I am wondering that maybe I can refactor that and maybe remove this params.merge from every link?

You could try something like this:

def my_path_helper(string, path_type, params)
  link_to(string, polymorphic_path([path_type], params.merge({layout: params[:layout]})))
end

See the docs for polymorphic path here and also this answer that provides an example.

Is this what you were looking for?
