Chapter 6. Helpers

Helpers are methods that are widely available throughout your application. They are primarily used within templates but are also available within controllers, given the tight coupling of controllers and views in Merb.

The use of helpers greatly simplifies the most common tasks application developers face. Consequently, their structure exhibits some of the best refactoring that web application developers typically run into. That said, we’re going through the helper source extensively, so that you will be comfortable with the methods you use all the time but also with designing your own.
