overwriting methods create/write with one2many object

on 5/14/13, 9:29 PM 5,580 views

In the view of the creation of a sale order, i put a number of section for each sale order line (a section allows me to decompose the sale order into multiple parts). When i create the sale order, i want the sale order section to be created too, with the same number i have put in the view. I've heard about overwriting create/write methods but i don't know how to do. Thanks, here is a part of my code :

class sale_order_line(osv.osv):

_name = 'sale.order.line'
_inherit = 'sale.order.line'

_columns = {
            'section_id': fields.many2one('sale.order.section', 'n° section', required=False, ondelete='cascade', select=True, readonly=True, states={'draft':[('readonly',False)]}),
            'number_section': fields.related('section_id', 'number', type='integer', string='N° section', store=False)

class sale_order_section(osv.osv):

_name = 'sale.order.section'
_columns = {
            'order_line': fields.one2many('sale.order.line', 'section_id', 'Order Lines', readonly=False),
            'number': fields.integer('n° section', help='permet de décomposer le devis en sous-sections'),
            'order_id': fields.related('order_line', 'order_id', type="many2one", relation='sale.order', string="Order", readonly=True, required=True),

ok but i don't understand where 'sec0001' come from . In fact, for each order line i have a column "number" where i put the number of section associated to the order line. Also, if i put the same number for 3 order lines for example, just one section has to be created. Thanks for your help

it was just a string which i put it , you can use your own no,,, for number in order line , i think you no need it because you have already a section Id , so why NUMBER ..... even you should use name of filed number as "name" then you can see section number in section Id , then you never need number in order line ,,,, as we have record id

Yes, it is the problem : i try to do 'number': order_line.number but it doesn't work. And a sale order is decomposed into multiples sections and here you create only one section ? I have number because if i write the same number for differents order lines, only one section is created

one sale order as one section Id am i right ??

no : one sale order has multiples sections (a section is a group of invoice lines), that is why i use a number ^^. However, a sale order line is associated with only one section

To override the create method just put your own create method in your sale.order.line class, in the following format:

    def create(self, cr, uid, vals, context=None):
         # Your additional code here
         return super(sale_order_line,self).create(cr,uid,vals,context)

The super(...) will ensure the original create method is still called and creates the object, while you code can add in any additional functionality you need.
