Rails 4 and associations

[boblin]

Hi,
I have trouble with association method in Rails 4.0.0 using like this:

class Group < ActiveRecord::Base
  has_many :members, class_name: 'User'
end

<%= show_for @group do |u| %>
    <%= u.association :members %>
<% end %>

It shows only:

Members: User

I found in show_for lib this:

sample = association.is_a?(Array) ? association.first : association

https://github.com/plataformatec/show_for/blob/master/lib/show_for/association.rb#L41

association was Array in rails 3.x, but since 4.0 is CollectionProxy.

Rasil 3:

Group.first.members.class
=> Array

Rails 4:

> Group.first.members.class 
=> ActiveRecord::Associations::CollectionProxy::ActiveRecord_Associations_CollectionProxy_User

So it looks that instead of

association.is_a?(Array)

there should be

association.is_a?(ActiveRecord::Associations::CollectionProxy)

.. at least for Rails 4
