Question

我正在继承res.partner模型，这是从v8到v10社区的迁移。

违规方法如下：

@api.depends('company_id')
def _get_country_code(self):
    """
    Return the country code of the user company. If not exists, return XX.
    """
    #context = dict(self._context or {})
    for partner in self:
        user_company = self.env['res.company'].browse(self.company_id)
        #NOTE: replace code name with your real field name where you want to see value 
        partner.code = user_company.partner_id and user_company.partner_id.country_id \
            and user_company.partner_id.country_id.code or 'XX'

@api.multi
def _get_uid_country(self): 
    """ Return a dictionary of key ids as invoices, and value the country code
    of the user company.
    """
    res = {}.fromkeys(self._get_country_code()) 
    return res

现在，当我点击客户端或供应商（res.partner）时，它会抛出这个：

我认为这与此行user_company = self.env['res.company'].browse(self.company_id)有关，但我不是百分百肯定。

有什么想法吗？

修改

旧API原始方法：

def _get_country_code(self, cr, uid, context=None):
    """
    Return the country code of the user company. If not exists, return XX.
    """
    context = context or {}
    user_company = self.pool.get('res.users').browse(
        cr, uid, uid, context=context).company_id
    return user_company.partner_id and user_company.partner_id.country_id \
        and user_company.partner_id.country_id.code or 'XX'

def _get_uid_country(self, cr, uid, ids, field_name, args, context=None):
    """ Return a dictionary of key ids as invoices, and value the country code
    of the user company.
    """
    context = context or {}
    res = {}.fromkeys(ids, self._get_country_code(cr, uid,
                                                  context=context))
    return res

Answer 1

您可以尝试替换此行：

user_company = self.env['res.company'].browse(self.company_id)

用这个

user_company = self.env['res.company'].browse(partner.company_id)

然后告诉我们

Answer 2

当你使用Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices(); if (pairedDevices.size() > 0) { String str = ""; for (BluetoothDevice device : pairedDevices) { mDevice = device; str = str+mDevice.getName()+", "; } }else{ System.out.println("No devices Found"); }时，self是一个RecordSet：

使用self时，RecordSet可以有0或1个或更多记录。如果RecordSet有一条记录，则此方法有效，但是如果它有多个记录，则会引发异常，因为它不会知道要问的女巫记录。因此，如果您使用@api.multi尝试始终循环记录集。 @ api.depends也像@ api.multi，self是一个RecordSet。

@api.multi

或者在这里使用for rec in self : rec.getSomeThing自我总是一个记录，但不推荐，因为它根据你视图中的记录数调用getSomeThing，所以对于表单视图来说这不是问题，因为它只有一个但是对于你可以想象的树视图。

Answer 3

我试图将它缩短一点：

uid_country = fields.Char(
    string="Country Code of Current User",
    compute="_get_uid_country")

@api.multi
@api.depends('company_id')  # there should be a better trigger field
def _get_uid_country(self):
    """ Compute country code by current users company """
    country_code = self.env.user.company_id.partner_id.country_id.code or 'XX'
    for partner in self:
        partner.update({'uid_country': country_code})

这应该足够了。在我看来，没有真正的触发器字段，每次调用伙伴时都会计算计算字段。但它应该有用。

Answer 4

您应该尝试_get_uid_country函数：

for record in self.browse(): result = {}.fromkeys(record._get_country_code(), False)

ValueError：预期单身人士：res.partner（1,12,29,30,36） - res.partner - Odoo v10社区
