Ruby on Rails

Hi!!

I have a few models that use a Photo polymorphic model. It's all good
and fine for saving or accessing the photos' attributes via console or
inspect or logger, but if I try to call them directly in the view
with, for example, @banner.photo.file, it returns a undefined method
'file' etc for nil:Nil

Photos are being uploaded via paperclip and all models are set with
has_one :photo, :as => :imageable and
accepts_nested_attributes_for :photo, :allow_destroy => true. And the
Photo model is set as belongs_to :imageable, :polymorphic => true and
has_attached_file :file.

These are the columns for the Photo model:

id:integer
file:string
imageable_id:integer
imageable_type:string
file_file_name:string
file_content_type:string
file_file_size:integer
(besides created_at etc)

In my view:

<% @banners.each do |b| %>
<%= b.photo.inspect %><br />
<% end %>
You can see the inspect at http://bdyvu2.hospedagemweb.net/

Many thanks in advance!! Going out of my mind here!! (been at it for
days!)
