Ok, last one - for your interest validates_length_of can be used for
this purpose. There is an open bug/patch on the rails trac regarding the
:within parameter but the :minimum works fine for me. As for the example
the method called on @item.images is #size and not #count so
-> @item.images.sho

Ok, i'm really stupid... i was taking a break (i've been on the pc for
several hours) and the problem came to me before reading your posts :D
Obviously the "if self.images.count" was wyyy too stupid! added the
necessary == 0 and everything is fine...
Thanks a lot anyway :)

Doh! I can't believe that I missed that.
You can also use if self.images.size.zero?
Just a little more readable.

Hi there all. Sorry if the question sounds silly but i'm rather new at
the 'mocking' stuff... So here is my problem (code helps more than
talking):
the model:
class Item < ActiveRecord::Base
...
has_many :images, :dependent => :destroy
...
protected
def validate
errors.add(:image
