[英]How to convert an existing related field into a computed one in Odoo 13?
I have this existing field:我有这个现有的领域:
picking_code = fields.Selection(
related='picking_id.picking_type_id.code',
readonly=True,
)
And I want to inherit it, remove the related
parameter and add a compute
one to set its value depending on some conditions.我想继承它,删除
related
参数并添加一个compute
一个以根据某些条件设置其值。
My attempt:我的尝试:
@api.depends('picking_id', 'picking_id.picking_type_id',
'picking_id.picking_type_id.code',
'move_id', 'move_id.picking_type_id',
'move_id.picking_type_id.code')
def _compute_picking_code(self):
_logger.critical('NEVER EXECUTES THIS' * 80)
for line in self:
if line.picking_id:
line.picking_code = line.picking_id.picking_type_id.code
else:
line.picking_code = line.move_id.picking_type_id.code
picking_code = fields.Selection(
related=False,
compute='_compute_picking_code',
)
The problem is that the compute method is never executed and I get the following error, which makes sense since if the compute method is not executed, no selection value is set to the field:问题是从未执行过计算方法,我收到以下错误,这是有道理的,因为如果未执行计算方法,则不会为该字段设置选择值:
AssertionError: Field stock.move.line.picking_code without selection - - -
断言错误:没有选择的字段 stock.move.line.picking_code - - -
Solved, if anyone is interested on the subject, it is a Selection
field, so if remove the related
parameter I have to specify again the list of tuples for the selection
parameter.解决了,如果有人对这个主题感兴趣,它是一个
Selection
字段,所以如果删除related
参数,我必须再次指定selection
参数的元组列表。
picking_code = fields.Selection(
selection=[
('incoming', 'Receipt'),
('outgoing', 'Delivery'),
('internal', 'Internal Transfer'),
],
compute='_compute_picking_code',
related=False,
readonly=True,
)
