Access params[] and local attributes in static class as *_filter
- by Mattias
Hi!
I'm trying to refactor some code and move some of my before_filter's from the controller to a class.
Before:
class UsersController < ApplicationController
before_filter :find_user
def find_user
@user = User.find(params[:id])
end
end
...
After
class FindUserFilter
def self.filter(controller)
@user = User.find(params[:id])
end
end
class UsersController < ApplicationController
before_filter FindUserFilter
end
class GuestbookController < ApplicationController
before_filter FindUserFilter
end
This results in an error because neither params[:id] nor @user is available/definable in the FindUserFilter-class.
Any idea how to fix this?
