[Rails] Using Helper Classes for standard processing

[Eric Anderson]

Most of the time the helper classes are geared towards generating 
boilerplate (or almost boilerplate) code for output. I am wanting to use 
a helper for boilerplate or almost boilerplate processing instead.

I have a certain process that needs to happen for several controllers. 
Instead of just copying the action to all the controllers I figured I 
would put the action in a Helper module and then simply use the helper 
class method to mixin that action to my controller.

When I tried to do this I get a message about the controller not being 
able to respond to the requested action. To get around this I manually 
required the helper file and manually mixed it into my controller module 
and that worked great.

My question is why didn't simply using the helper class method work? The 
code looks seems to just require the file and do an include in a 
class_eval. Basically it is doing the same thing I did manually. So why 
doesn't this work?

The bug is not that big of a deal, but if I can simply my code I would 
like to. Anybody have any ideas?
