Passing Arguments to before_filter

I want to put a before_filter in application.rb, as follows:

before_filter :do_something, :except_controller => [:admin]

def do_something(options)   options.stringify_keys!   unless options[:except_controller].include?(controller_name)     # do something useful   end end

Where I'm blocking is on how to get the 'options' data in the do_something method. I think I can write this as:

Thanks,

Hi --

I want to put a before_filter in application.rb, as follows:

before_filter :do_something, :except_controller => [:admin]

def do_something(options)   options.stringify_keys!   unless options[:except_controller].include?(controller_name)     # do something useful   end end

Where I'm blocking is on how to get the 'options' data in the do_something method. I think I can write this as:

The way I've done this in the past, which may or may not be the slickest way to do it, is along the lines of:

  class MyController < ApplicationController     before_filter :only => "whatever" do |controller|        controller.some_method(1,2,3)     end

    def some_method(a,b,c)        ...     end   end

The proc has the controller object itself yielded to it, so you can then call the method on that object with whatever arguments you need.

The particular case you've got, where you seem to be testing for whether this controller needs a particular filter, looks like it would probably better handled with skip_before_filter and friends. But anyway, you can grab the controller object and call methods on it directly.
