Re: [Rails] Re: How to "intercept" each action call?

Thanks for your help Dheeraj, but I'm trying to do something like Responders.

Responders has a respond_to :html in controllers, that is used in each action call to respond_with.

The thing is: call a specific method that is located inside my gem for every action call. This method should be able to modify the attribute that was passed.

I have no idea to make this work.

You need a before_filter.

Hi! 

I'm a RoR beginner and I'm trying to make a gem that can "intercepts" all action from my controllers.

I would like to do something like that:

class ApplicationController < ActionController::Base

  include MyGem

end

class MyController < ApplicationController

  do_something_to :some_attribute

  def index

    respond_with(@some_attribute)

  end

end

In each call of index or other action from MyController, I want that MyGem execute "do_something_to" modifying the value of "some_attribute". Is it possible?

Thanks,

Lauro Caetano
