Module: Sinatra::Hat::Actions

Included in:
Maker
Defined in:
lib/sinatras-hat/actions.rb

Overview

Contains all of the actions that Sinatra’s Hat supports. Each action states a name, a path, optionally, the HTTP verb, then a block which takes a request object, optionally loads data using the :finder or :record options, then responds, based on whether or not the action was a success

NOTE: only the :create action renders a different :failure
