Hi all,

I would like to know how to force the customer to have at least one product inside quotations.

With this, they will not be able to save the quotation ( so create a new line in the database) if there is no product.

I was thinking to add only required=true for the order_line but it is not working.

Someone has an idea?

-----EDIT SOLUTION----

It is working with this solution inside the create function:

    def create(self, cr, uid, vals, context=None):
        context = context or {} 
        if not vals['order_line']:
           raise osv.except_osv(_('Error!'),_('You cannot confirm a Quotation which has no line.'))

Many thanks,

Selverine
