Using Helpers in Rails Applications

What is a helper

Helper is a module containing methods that assist a view. Helper methods are used to generate HTML, XML or Javascript. So, the helper extends the behavior of a template.

Each controller gets its own helper module. If the controller is named BlogController, then Rails will look for the helper BlogHelper in the file blog_helper.rb. However, this is generated automatically using the controller generation script.
