How to change layouts based on every action in Rails.
We have more than one layouts for individual action and need to change this based on action or page, how to do that.
Very easy, first you can create layouts in layouts folder as like
- about_layout.html.erb
- home_layout.html.erb
- contact_layout.html.erb
- product_layout.html.erb
now in the controller
class PagesController < ApplicationController
layout :determine_layout
def home
end
def product
end
def about
end
def contact
end
private
def determine_layout
case action_name
when "home"
"home_layout"
when "product"
"product_layout"
when "about" #=> or you can use a comma for the same layout in 2 or 3 actions like when "home","contact"
"about_layout"
when "contact"
"contact_layout"
end
end
end
This called action base layout.
