我将某些模块从v7迁移到v10
现在我有这些继承res.partner
@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.users'].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 default_get(self, field_list):
""" Load the country code of the user company to form to be created.
"""
# NOTE: use field_list argument instead of fields for fix the pylint
# error W0621 Redefining name 'fields' from outer scope
context = {}
res = super(ResPartner, self).default_get(field_list)
res.update({'uid_country': self._get_country_code })
return res
@api.multi
def _get_uid_country(self):
""" Return a dictionary of key ids as invoices, and value the country code
of the user company.
"""
context = dict(self._context or {})
res = {}.fromkeys(self._get_country_code())
return res

我也在努力解决这个问题，你认为从v8而不是v7迁移到v10会更容易吗？
有什么想法吗？
答案 0 :(得分：2)
预期的单身人士：
类方法需要单个调用对象（Single Browsable Record）来调用该方法并假设它将通过多个调用对象（可浏览记录集）调用然后方法不能确定它应该处理哪个对象，因此会引发错误预期单身。
新的API装饰器用于定义方法调用模式，方法是否只允许单个对象或多个对象调用此方法。
<强> @ api.one
这个装饰器会自动在RecordSet记录上循环。 Self被重新定义为当前记录
注意： 警告：返回的值放在列表中。 Web客户端并不总是支持这一点，例如按钮动作 方法。在这种情况下，您应该使用 @ api.multi 来装饰您的方法，并可能在 self.ensure_one（）中调用 方法定义。
<强> @ api.multi
Self将是没有迭代的当前RecordSet。这是默认行为（多个可浏览对象）。返回非premitive类型数据（列表，字典，函数）的方法必须用 @ api.multi
进行修饰@ api.model
此装饰器会将旧的API调用转换为装饰函数，以转换为新的API签名。它允许礼貌的时候 迁移代码。 Self在此装饰器修饰的方法中不包含任何记录/记录集。
所以简单地这样打电话
<强> self.env [ 'MODEL_NAME']。METHOD_NAME（参数）
尝试使用以下代码：
@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'
将 default_get（）方法api从 @ api.multi 更改为 @ api.model
答案 1 :(得分：2)
Please try this
@api.multi
def _get_country_code(self):
code =False
for partner in self:
user_company = self.user_id
#it will return the current login-ed user id
code = user_company.partner_id and user_company.partner_id.country_id and user_company.partner_id.country_id.code or 'XX'
return code
