如何修改原class里的方法
-
按照Odoo的风格,理论上:
Class A中的方法可以由继承A的ClassB中被修改 ?
问题如下:
在stock.py中的:
[quote]
class stock_picking(models.Model):
_name = "stock.picking"
_inherit = ['mail.thread']
_description = "Transfer"
_order = "priority desc, date asc, id desc"
def _set_min_date(.....
[/quote]
有
[quote]
def create_lots_for_picking(self, cr, uid, ids, context=None):
lot_obj = self.pool['stock.production.lot']
opslot_obj = self.pool['stock.pack.operation.lot']
to_unlink = []
for picking in self.browse(cr, uid, ids, context=context):
for ops in picking.pack_operation_ids:
for opslot in ops.pack_lot_ids:
if not opslot.lot_id:
print '=============not find stock.production.lot, create lot:',opslot.lot_name,ops.product_id.id,opslot.lot_weight
lot_id = lot_obj.create(cr, uid, {'name': opslot.lot_name, 'product_id': ops.product_id.id}, context=context)
opslot_obj.write(cr, uid, [opslot.id], {'lot_id':lot_id}, context=context)
#Unlink pack operations where qty = 0
to_unlink += [x.id for x in ops.pack_lot_ids if x.qty == 0.0]
opslot_obj.unlink(cr, uid, to_unlink, context=context)
[/quote]
现在需要修改这个方法,新建模块后:
[quote]
class dy_stock_picking(models.Model):
inherit = 'stock.picking'
def create_lots_for_picking(self, cr, uid, ids, context=None):
print 'dy.stock.picking==============='
lot_obj = self.pool['stock.production.lot']
opslot_obj = self.pool['stock.pack.operation.lot']
to_unlink = []
for picking in self.browse(cr, uid, ids, context=context):
for ops in picking.pack_operation_ids:
for opslot in ops.pack_lot_ids:
if not opslot.lot_id:
print 'dy.stock.picking=============not find stock.production.lot, create lot:',opslot.lot_name,ops.product_id.id
lot_id = lot_obj.create(cr, uid, {'name': opslot.lot_name, 'product_id': ops.product_id.id, 'lot_weight': opslot.lot_weight}, context=context)
opslot_obj.write(cr, uid, [opslot.id], {'lot_id':lot_id}, context=context)
#Unlink pack operations where qty = 0
to_unlink += [x.id for x in ops.pack_lot_ids if x.qty == 0.0]
opslot_obj.unlink(cr, uid, to_unlink, context=context)
[/quote]
运行后发现,没有成功:
[img [检测到链接无效，已移除] /img]
还是调用了原来的方法
什么原因?
