@Jeremy:
#1 seems to be the easiest, but #2 is the best solution.
Here's my view of how this can work:
class TasksController < ApplicationController
# Specify which class has the generic scaffolding methods
scaffold :my_custom_scaffold_class
# or we bundle a generic class with the gem
scaffold
# Overriding is possible
def show(id)
# instance variable is already injected by our gem
# do something with the @task
end
end
or even
class ApplicationController < ActionController::Base
scaffold
end
to propagate to all controllers which inherit from ApplicationController.
