I have the following validation on and ''Order'' model:
validates_presence_of :order_lines, :message => ''missing one or more
products.'', :on => :save
Ok, great. An order has to have products. Ok.
Problem is, there are some old orders that don''t have lines
(don''t ask) and
in the admin tool we need to be able to work on these orders.
Problem is that we can''t save them since they technically fail
validation.
In the admin tool I want to be able to get around this.
I''m using two methods to update order status, depending on if
we''re doing
lots of ''em at a time:
Order.update(params[:item].keys, params[:item].values)
Or just one:
@order = Order.find(params[:id])
@order.update_attributes(params[:order])
So, can anyone offer any advice in this scenario to bypass validations and
update the objects/save them?
Thx,
Hunter

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! ~Dave -- Dave Silvester Rent-A-Monkey Website Development http://www.rentamonkey.com/ PGP Key: http://www.rentamonkey.com/pgpkey.asc
Another choice is to create the base model without the validations and then inherit from it to add the validations. In the normal case use the properly validated model, but when necessary fall back to the base model. pth
