Odd behaviour with postgresql and rails 3?

Hi I am seeing something odd with my postgresql database with Rails 3,
there is one model I can’t update from Rails. From the rails console I
can update other models, but not this particular model.

The model is simple, I can create a records, but after this I can’t
update a record. It was working before and now it’s not. I’ve logged
into the database using pgadmin3 and executed a SQL statement to
update a field successfully. However from Rails all I get is an output
like this (with no update, missing in the output is the actually SQL
for update)

irb(main):023:0> s.save
(0.1ms) BEGIN
(0.1ms) COMMIT
=> true

Has anyone come across a problem like this with pgsql and Rails 3?

My models is simple I have a user model and a snippet model, the user
model is a devise model, it works file, the snippet model does not.

class User < ActiveRecord::Base
has_many :snippets, :dependent => :delete_all

class Snippet < ActiveRecord::Base
belongs_to :user

Kind Regards,

OK I narrowed it down to user error, nothing is wrong!
