「update_fields」是這個函數

我得到這個錯誤訊息節約Django的模式窗體「update_fields」是這個函數

「update_fields」是這個函數 我沒有得到任何想法，爲什麼一個無效的關鍵字參數無效關鍵字參數這個錯誤發生得到同樣的錯誤在這兩個更新和插入操作這是我的看法代碼

form = CompanyForm(request.POST, instance=company) 
if form.is_valid(): 
     company = form.save(request.user)

我的情態形式

class CompanyForm(forms.ModelForm): 
    class Meta: 
     model = Company 
     fields = ('name','organisation', 'currency') 

    def __init__(self, *args, **kwargs): 
     super(CompanyForm, self).__init__(*args, **kwargs) 
     if self.instance.id: 
      self.fields['currency'].widget.attrs['readonly'] = True 

    def clean_currency(self): 
     if self.instance.id: 
      return self.instance.currency 
     return self.cleaned_data.get('currency') 

    def save(self, operator, commit=True): 
     company = super(CompanyForm, self).save(commit=False) 
     company.operator = operator 
     company.save() 
     return company
