my models: content has_many keys I don't understand how is it possible that empty array will have 'build' method?
@content = Content.create(:text => 'test') => #<Content id: 3, text: "test", created_at: "2010-04-28 19:04:19", updated_at: "2010-04-28 19:04:19">
@content.keys =>
but this works. can someone explain how can it be? @content.keys.build => #<Key id: nil, name: nil, content_id: 3, created_at: nil, updated_at: nil>
Thanks
