Hello all! This is my first time posting to the list, so be
gentle. 
Here’s my setup… I’ve created a controller class method for
performing some access control actions during a before_filter
callback. What I’d like to do is access the params from within the
class method without having to explicitly pass them in the
controller. I’d like to check the path in the url for some finer
grained authentication.
I’ve tried to do a couple of different ways, but I think params are
either out of scope or not created by the time the before filter
runs.
Is what I’m proposing possible?
Example of what I’d like to do:
in controller…
class ProjectController < ApplicationController
class_method_call ‘do something’
… rest of controller code …
end
in lib…
module AccCheck
def self.included(in_sub)
in_sub.extend(ClassMethods)
end
module ClassMethods
def class_method_call(in_string)
before_filter do |c|
if !params[:id].nil?
… check access …
end
end
end
end
end

There is no way params could be accessible at the class level because if
it did, there would be a huge clash if your app ever exceeded one
session (which is fairly likely after you deploy)! Imagine the params
hash continuously getting over written whenever a new request would come
in. There would be chaos, mass looting, and a sharp rise in suicides.
Why can’t you have: class_method_call(in_string, params) again ???

Yikes… it sounds like if I could do that it could be a clash of
biblical proportion. I really have no reason for not being able to
pass the params in the controller. I was curious to know if something
like that was accessible with the class method I was creating.
Thanks for the info.
