My subject is probably not the best description, so here is an example of what I am trying to do.
class ExampleController < ApplicationController include EventManager
def action @name = 'John' event(:event, :context) do @name << ' Doe' end end end
module EventManager def event(*args) # Retrieve the module based on the parameters. # Call EventManager::Event::Context.before if it exists with access to the variables from where event was called. yield if block_given? # Call EventManager::Event::Context.after if it exists with access to the variables from where event was called. end
module Event module Context def before puts "Hi John" if @name == 'John' end
def after puts "Who?" if @name != 'John' end end end end
Basically I want to be able to store methods in nested modules for separation, but be able to call them dynamically within controller actions via the event method.
My current solutions involves module_function for all the before and after methods and retrieving controller information by passing the controller to each action and using send and instance_variable_get/set which is less than ideal in my opinion.
Any suggestions, or hints?
