Rails - Add class if Radio button is checked

Question

How to get the value of the radio button from the form_for helper?

Using SLIM.

=form_for(@foo) do |f|
  label[class="#{ f.type.value == 'type 1'? 'foo' : 'bar'}"]
    | Type 1
    = f.radio_button :type, 'Type 1' 
  label[class="#{ f.type.value == 'type 2'? 'foo' : 'bar'}"]
    | Type 2
    = f.radio_button :type, 'Type 2'

The value method doesnt exist. How to access the value of the form helper's radio method?

@emaillenin no mentioning of accessing the value [Rails](http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#method-i-radio_button_tag) — Vivek Chandra, Mar 01 '14 at 11:49

As per this question, you may be able to use the actual @foo variable:

label[class="#{ @foo.type == 'type_2'? 'foo' : 'bar'}"]
