Yes. In your module you've defined an instance method not a class
method.
But this:
> class CarePhase < ActiveRecord::Base
> include ModelHelper
>
> pretend_helper("hi!")
Is the class trying to call the method, which fails because the class
doesn't know about the 'pretend_helper' method.
What you have would work fine if you did this:
CarePhase.new.pretend_helper('hi')
If you really do want a class method, try changing the method definition
in PretendHelper to:
def self.pretend_helper(msg)
puts msg
end
And then you would be fine to call:
CarePhase.pretend_helper('hi')
Hope that helps.
