Using App Guts in Your Plugins
You know how Rails Engines allow you to reuse controllers, helpers, models and views? Well, you can do it with plugins too. ezmobius over at Caboo.se just posted how. Put these four lines in the plugins init.rb …
config.controller_paths << File.join(directory, 'app',
'controllers')
$LOAD_PATH << File.join(directory, 'app', 'controllers')
$LOAD_PATH << File.join(directory, 'app', 'models')
$LOAD_PATH << File.join(directory, 'app', 'helpers')Now you can add an app/ directory in the root of your plugin with controllers, helpers, models and views. Sweet!
Also, note that you need to add something like the following in all of the plugins controllers …
FooController.template_root = File.join(File.dirname(__FILE__), '..', 'views')I have been using Rails for websites more than for applications as most of the sites I create use administration areas. Sites often times have things in common such as news, events, contact form, etc. This tip will come in really handy. I could also see it used for an authentication system as mine often function the same.
