CheckPath

CheckPath extends ActionView::Helpers::UrlHelper in Rails application. It just add some methods, such as root_path?, post_path?(id: 1), and so on.

Add this line to your application's Gemfile:

gem 'check_path'

And then execute:

$ bundle

When you add to Gemfile and run bundle install, you can use some methods in view files.

If your config/routes.rb is follows:

Rails.application.routes.draw do
  resources :posts, only: [:index, :new, :edit, :show]

  root 'posts#index'
end

Then following methods are available in your view files:

• root_path?
• posts_path?
• new_post_path?
• edit_post_path?(:id)
• post_path?(:id)

For example, you can check current page is new_post_path or not in app/views/layouts/application.html.erb:

<% if new_post_path? %>
  <!-- Show only in new_post_path -->
<% end %>

As you know, the logic of these methods are as follows. So you might this gem is not required.

def root_path?
  current_page?(root_path)
end
