What is the difference between _url and _path while using the routes in rails

Question

When we define routes in routes.rb using the name like map.some_link.We can use the link in two ways- some_link_url, some_link_p

Answer 1

The _url helper generates a string containing the entire URL, while the _path helper generates a string containing the relative path from the root of the application, e.g.:

photos_url  # => "http://www.example.com/photos"
photos_path # => "/photos"

As per Rails Guides - Routing.
