Re: best way to generate a fieldby
And there is also another problem - since you use randomness the code will change every time the field is recomputed. For non stored files that means all the time. I assume that's not what you want (?). So looking at the specifics maybe using computed field is not such a good idea in this case...
The second one looks almost correct, but I don't know where did the "related_vals" came from. The line should read:
self.ean13 = barcode.get_barcode('ean13', code).get_fullcode()"_compute_default_code" looks very incomplete. Also, you use the old API (style) for defining model fields.LudwikOn Tue Jan 27 2015 at 12:12:48 PM Fabrizio Mancini <firstname.lastname@example.org> wrote:Hi Ludwik,thanks for the response.Let me see if i have understood:#overwrite default_code of product_product'default_code' : fields.char(compute='_compute_default_code')'ean13': fields.char('EAN13 Barcode', size=13, help="International Article Number used for product identification.", compute='_compute_ean13')def _compute_default_code(self):self.pool.get('ir.sequence').get(cr, uid, 'product.product')@api.depends('default_code')def _compute_ean13(self):code = unicode(randint(0,99999)).rjust(5,'0') + unicode(self.default_code).rjust(7, '0')related_vals['ean13'] = barcode.get_barcode('ean13', code).get_fullcode()Is this correct for you?Thanks in advacne2015-01-27 11:48 GMT+01:00 Ludwik Trammer <email@example.com>:
Looks like a job for computed fields (provided you don't intend to be able to later edit them by hand independently of the fields they were generated from).Computed fields documentation:L.On Tue Jan 27 2015 at 10:52:06 AM Fabrizio Mancini <firstname.lastname@example.org> wrote:Hi everyone,i need to generate automatically two fields (ean13 and default_code) on the product_product model.The default code is generated by a sequence, and the ean13 is generated from a random number plus the default code.
