Kinda sounds to me like you want: update_attribute_with_validation_skipping

See: http://api.rubyonrails.com/classes/ActiveRecord/Validations.html#M000796

Though as far as I know, there's no way of doing update_attributes and 
bypassing all validations.

Another possibility for you would be to put validation conditions into your 
model using :if => 

validates_presence_of :order_lines, :message => 'missing one or more 
products.', :on => :save, :if => some_condition

HOWEVER, as far as I know, the models aren't supposed to be tightly linked to 
the controllers and have a good degree of enforced separation between them, 
so if you were going to check for the presence of a session variable (or 
something) in your model, I think you'll be out of luck as that kind of stuff 
belongs in the controller.

There's probably a way you could do it but I can't think right now, sorry!
