ValueError异常：预计单：res.partner - Odoo V10社区

Question

我移植一些模块从V7到V10

现在我有这些方法，其继承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 

我有这个错误每个一次，我尝试创建或阅读合作伙伴：

我这个挣扎，另外，你认为它会更容易从V8迁移，而不是V7，V10来？

任何想法？

Answer 1

预期的Singleton：

类方法需要单个调用对象（单可浏览记录）调用该方法，并假设它会通过多个调用的对象（可浏览记录集）调用然后方法不能以确定它应该处理哪个对象，因此它会产生一个错误期望的单身人士。

新API装饰器用于定义方法调用模式，无论方法是只允许单个对象还是多个对象调用此方法。

@ api.one

这个装饰上的记录集的记录自动循环给你。自我被重新定义为当前记录

注意： 注意：返回的值放在列表中。这并不总是被Web客户端支持，例如，按钮动作 方法。在这种情况下，您应该使用@ api.multi来修饰您的方法，并且可能会调用self.ensure_one（） in 的方法定义。

@ api.multi

自将不迭代当前Recordset。这是默认行为（多个可浏览的对象）。返回非premitive类型的数据（列表，字典，函数）方法必须装饰@ api.multi

@ api.model

这个装饰将旧的API调用转换为装饰功能，新API签名。它允许在 迁移代码时有礼貌。自身不包含由此装饰器装饰的方法中的任何记录/记录集。

所以，简单地调用此类

self.env [ '模型名称']。METHOD_NAME（参数）

用下面的代码尝试：

@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' 

变化default_get（）从方法API @ api.multi到@ api.model

Answer 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
