ValueError異常：預計單：res.partner - Odoo V10社區

Question

我移植一些模塊從V7到V10

現在我有這些方法，其繼承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 

我有這個錯誤每個一次，我嘗試創建或閱讀合作伙伴：

我這個掙扎，另外，你認爲它會更容易從V8遷移，而不是V7，V10來？

任何想法？

Answer 1

預期的Singleton：

類方法需要單個調用對象（單可瀏覽記錄）調用該方法，並假設它會通過多個調用的對象（可瀏覽記錄集）調用然後方法不能以確定它應該處理哪個對象，因此它會產生一個錯誤期望的單身人士。

新API裝飾器用於定義方法調用模式，無論方法是隻允許單個對象還是多個對象調用此方法。

@ api.one

這個裝飾上的記錄集的記錄自動循環給你。自我被重新定義爲當前記錄

注意： 注意：返回的值放在列表中。這並不總是被Web客戶端支持，例如，按鈕動作 方法。在這種情況下，您應該使用@ api.multi來修飾您的方法，並且可能會調用self.ensure_one（） in 的方法定義。

@ api.multi

自將不迭代當前Recordset。這是默認行爲（多個可瀏覽的對象）。返回非premitive類型的數據（列表，字典，函數）方法必須裝飾@ api.multi

@ api.model

這個裝飾將舊的API調用轉換爲裝飾功能，新API簽名。它允許在 遷移代碼時有禮貌。自身不包含由此裝飾器裝飾的方法中的任何記錄/記錄集。

所以，簡單地調用此類

self.env [ '模型名稱']。METHOD_NAME（參數）

用下面的代碼嘗試：

@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' 

變化default_get（）從方法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
