ValueError:计算方法分配失败（Python3 odoo）

Question

我的代码中有三个计算函数。 但我错了

Odoo Server Error

Traceback (most recent call last):
  File "/vagrant/odoo/odoo/addons/base/models/ir_http.py", line 237, in _dispatch
    result = request.dispatch()
  File "/vagrant/odoo/odoo/http.py", line 682, in dispatch

  File "/vagrant/odoo/odoo/fields.py", line 979, in __get__
    raise ValueError("Compute method failed to assign %s.%s" % (record, self.name))
Exception

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/vagrant/odoo/odoo/http.py", line 638, in _handle_exception
    return super(JsonRequest, self)._handle_exception(exception)
  File "/vagrant/odoo/odoo/http.py", line 314, in _handle_exception
    raise exception.with_traceback(None) from new_cause
ValueError: Compute method failed to assign meeting.request(<NewId 0x7f4760a316d8>,).description

我在函数中指定了空值。
如self.request\u srcmst\u names=''、self.date=''、self.editable=False
但它仍然不能工作。我不知道哪个函数是错的

class MeetingRequest(models.Model):

    _name = 'meeting.request'

    request_srcmst_names = fields.Char(compute=_compute_request_srcmst_names)
    date = fields.Date(compute=compute_date, search=search_date)

    @api.depends('request_srcmst_ids')
    def _compute_request_srcmst_names(self):
        self.request_srcmst_names = ''
        for record in self:
            name = []
            for request_srcmst in record.request_srcmst_ids:
                name.append(request_srcmst.meeting_srcmst_id.name)
            record.request_srcmst_names = ', '.join(name)

    @api.depends('start_date')
    def compute_date(self):
        self.date = ''
        for record in self:
            if record.start_date:
                real_date = pytz.utc.localize(datetime.datetime.strptime(record.start_date, '%Y-%m-%d %H:%M:%S')).astimezone(pytz.timezone(config['timezone'])).date()
                record.date = real_date

class MeetingRequestSrcmst(models.Model):

    _name = 'meeting.request.srcmst'

    editable = fields.Boolean(compute=_compute_editable)

    def _compute_editable(self):
        self.editable = False
        for record in self:
            if record.hre_empbas_id.res_users_id.id == self.env.uid or record.create_uid.id == self.env.uid:
                record.editable = True

如何修复该函数？请给我一些建议。谢谢

Answer 1

我认为这是语法错误。您忘了在函数名周围加引号。计算函数名应该在引号内–compute='compute\u date'。搜索功能也是如此

就你而言

date = fields.Date(compute='compute_date', search='search_date')
request_srcmst_names = fields.Char(compute='_compute_request_srcmst_names')

在计算字段的函数中，可以删除：

self.editable = False
self.date = ''
self.request_srcmst_names = ''
