ruby on rails - How to have a route accessed only from code and not from URL -

i see when name route in config file, like:

  match 'controller/posts' => 'controller#posts', :as => 'posts'

it creates named route controller action.

but route needs accessed code. when click on posts button view, should execute user.

but when executes www.xyz.com/posts, should not try execute this. possible ?

i'm not sure why go way. sounds want able call specific bit of code controller. route won't work reasons mentioned (it available on browser).

instead, should extract bit of code , put in it's own library.

lib/foobar.rb:

module foobar   def my_method     # add code here   end end

then can call whereever want in code.
