Rails - Mar 2006 - Accessing overridden method

I have two model classes:

class Item < ActiveRecord::Base
  belongs_to :channel, :counter_cache => true
  validates_presence_of :channel
end


class Channel < ActiveRecord::Base
  has_many :items, :dependent => true
end


In the Channel controller I have variable channel.items, an Array of
Items.  I would like to use the Array find method.  However,
channel.items.find() is a Rails database query method.  Is there any
way I can access the built-in Array find() method?

TIA,
  Jeffrey

Array.find is a synonym for detect.

Yep and you can always use a to_a to make sure you are using array find:

>> channel.items.to_a.find
