Question

我在保存django模式表单时收到此错误消息

＆＃39; update_fields＆＃39;是此函数的无效关键字参数 我不知道为什么会发生这种错误在更新和插入操作中获得相同的错误这是我的观看代码

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

我的模态表格

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
