Question

需要帮助访问表单clean_data或clean function中的隐藏输入。在搜索约1小时后，无法在此处找到解决方案并且 Django docs 。

class AccountForm(forms.ModelForm):

class Meta:
    model = Account
    #action = forms.CharField(widget=forms.HiddenInput()) <--- also tried this

    exclude = [
        "a_account_number"
    ]

# Validate that there isn't already an account that exists with a similar company name during account creation
def clean_a_company_name(self):
    logging.debug("Value of action %s") % self.data.__getitem__('action')

    if Account.objects.filter( a_company_name = self.cleaned_data['a_company_name']).exists() and % self.data.__getitem__('action')== 'create':
        logging.debug("In account views - form validation - clean_a_company - company already exists raising exception *****************")
        raise forms.ValidationError(u"An organization with this name and owner already exists. Change the Organization name or edit Organization Account information instead of creating a new Organization Account")
    return self.cleaned_data["a_company_name"]

上面给出了unicode错误。我也尝试过：

%self.fields['action']

因此，您尝试访问清除action方法中的a_company_name字段？您无法访问字段的clean方法中的其他字段。您应该使用表单的clean方法。

来自django docs：

Form子类的clean（）方法。此方法可以执行任何验证这需要访问多个表格中的字段一次。这是你可以把东西放在哪里检查如果提供了字段A，则字段B 必须包含有效的电子邮件地址和之类的。
