I have implemented the Role-Right authorization recipe in Rails Recipes
(recipe 32), which works fine, but I’d like to auto-populate the Rights
table with all the actions in my system … since the system is rather
large. Doing it manually, from a administrative interface or the
console, is going to be annoying … and it would have to be updated
every time I change the number of actions …
I attempted to write a migration to find all my controllers, load each
one, and call “Controller.public_methods - Controller.hidden_actions” to
give me the actions defined in that controller, but for a controller
with one action, it definitely doesn’t give me just one action back …

Now these are definitely not the actions my controller is capable of
responding to … is there any way to find out exactly what actions a
controller responds to?. Any ideas? If this is the wrong approach, any
suggestions on another? Anything obvious I’m missing?
