Rails - Jan 2006 - before_filter: how to give :except more than 1 value?

Hi all

I have the following class:

class MemberController < ApplicationController
  before_filter :authorize, :except => :index

  def index
  ...
end

Now I want to give the before_filter more than one :except argument. I 
tried :except => {:index, :login}, but this didn''t work.

How can i accomplish this?

Thanks a lot and have a nice day,
Josh

try array.
  before_filter :authorize, :except =>[:index, :except]

Try putting it in an array rather than a hash, e.g.

before_filter :authorize, :except => [:index, :login]

See under ''Filter Conditions'':
http://api.rubyonrails.com/classes/ActionController/Filters/ClassMethods.html#M000127

Thank you. Is %w{ index, login } OK, too?

Thanks a lot.

But what exactly creates the array now and what the hash?

%w{} should create an array, right?

The bare curlies create a hash, braces create an array.

%w{index login} will also create an array, but be careful not to
do %w{index, login} with the comma because then the comma becomes
part of the first array element.

e.g.
irb(main):001:0> a1 = [''index'',''login'']
=> ["index", "login"]
irb(main):002:0> a2 = %w{index login}
=> ["index", "login"]
irb(main):003:0> a3 = %w{index, login}
=> ["index,", "login"]

And note that:

%w{index login}

creates this array:

[''index'', ''login'']

and this:

[:index, :login]

creates an array of symbols rather than an array of strings.

That should not be a problem, however, because send() accepts strings 
too.
