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

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. 2012/5/11 Dheeraj Kumar <a.dheeraj.kumar-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>> You need a before_filter. > > http://edgeguides.rubyonrails.org/action_controller_overview.html#filters > > > > Dheeraj Kumar > > On Saturday 12 May 2012 at 5:53 AM, Lauro Caetano wrote: > > 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".

I don''t understand your exact request, but let''s see if this helps you. You can run filters before every action call. Inside the filter method/class, you can call your gem''s methods. Also, they can modify the params hash. See this for two examples, one showing a filter method, and another a filter class. http://stackoverflow.com/questions/2913113/access-params-and-local-attributes-in-static-class-as-filter Dheeraj Kumar On Saturday 12 May 2012 at 6:20 AM, Jeremy Walker wrote:> > > On 12 May 2012 01:48, Lauro Caetano <laurocaetano1-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org (mailto:laurocaetano1-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org)> wrote: > > 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.

I''m trying to do this:
class ApplicationController < ActionController::Base
include MyGem
end
class TasksController < ApplicationController
injector_to :task
def show
respond_with(@task)
end
end
When the action ''show'' is called, the "injector_to"
should inject the @task
for me.
In other words, injector_to makes "Task.find(params[id])" for me in
this
case.
Other example: If I have this action ->
def create
respond_with(@task)
end
the injector_to should do the hard work, instantiating the @task and saving
it.
I think that I''ve explained better now.

That makes sense. Two methods spring to mind. 1) A generic controller than handles the methods that other controllers inherit from. You then set the variable name and class in each child controller, maybe via overloaded methods or through your injector_to method. 2) Your gem adds injector_to to ActiveController. When called it dynamically adds the standard methods to the controller. You then patch ActiveController so rather than looking for the "show" method, it looks for "injected_show", etc, which calls the scaffold code, then calls the controller-specific "show" method if there is one. That''s the nicest way of doing it from an end-user point of view. I actually quite like this idea. If you want some help writing them Gem, let me know offlist and I''ll happily help.> >>> When the action ''show'' is called, the "injector_to" should inject the > @task for me. > In other words, injector_to makes "Task.find(params[id])" for me in this > case. > > Other example: If I have this action -> > > def create > respond_with(@task) > end > > the injector_to should do the hard work, instantiating the @task and > saving it. > > I think that I''ve explained better now. > > 2012/5/11 Jeremy Walker <jez.walker-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> > >> >> >> On 12 May 2012 01:48, Lauro Caetano <laurocaetano1-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: >> >>> 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.

I understand. See the link I posted, where the OP does exactly your requirement.
Here''s some code:
class ApplicationController < ActionController::Base
include MyGem
end
class TasksController < ApplicationController
before_filter :find_task
def find_task
@task = Task.find(params[:id])
# Some other operation involving MyGem if you need...
end
def show
respond_with(@task)
end
end

@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.
