Python Django表单集标签

我有一个表单继承了其他两个表单。在我的表单中，我想更改在父表单中定义的字段的标签。有人知道如何做到这一点吗

我试图在我的

\uuuu init\uuuu

中执行此操作，但它抛出一个错误，指出“'RegistrationFormTOS'对象没有属性'email'”。有人知道我怎么做吗

谢谢

这是我的表格代码：

from django import forms
from django.utils.translation import ugettext_lazy as _
from registration.forms import RegistrationFormUniqueEmail
from registration.forms import RegistrationFormTermsOfService

attrs_dict = { 'class': 'required' }

class RegistrationFormTOS(RegistrationFormUniqueEmail, RegistrationFormTermsOfService):
    """
    Subclass of ``RegistrationForm`` which adds a required checkbox
    for agreeing to a site's Terms of Service.

    """
    email2 = forms.EmailField(widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=75)), label=_(u'verify email address'))

    def __init__(self, *args, **kwargs):
        self.email.label = "New Email Label"
        super(RegistrationFormTOS, self).__init__(*args, **kwargs)

    def clean_email2(self):
        """
        Verifiy that the values entered into the two email fields
        match. 
        """
        if 'email' in self.cleaned_data and 'email2' in self.cleaned_data:
            if self.cleaned_data['email'] != self.cleaned_data['email2']:
                raise forms.ValidationError(_(u'You must type the same email each time'))
        return self.cleaned_data

您可以通过“字段”命令访问表单中的字段：

self.fields['email'].label = "New Email Label"

这样您就不必担心表单字段与表单类方法的名称冲突。（否则不能有名为“clean”或“is_valid”的字段）直接在类主体中定义字段主要是为了方便。

您应该使用：

def __init__(self, *args, **kwargs):
    super(RegistrationFormTOS, self).__init__(*args, **kwargs)
    self.fields['email'].label = "New Email Label"

---

注意：首先您应该使用超级调用。

它不适用于模型继承，但您可以直接在模型中设置标签

email = models.EmailField("E-Mail Address")
email_confirmation = models.EmailField("Please repeat")

---

定义表单时，您可以将

标签

设置为字段的属性

class GiftCardForm(forms.ModelForm):
    card_name = forms.CharField(max_length=100, label="Cardholder Name")
    card_number = forms.CharField(max_length=50, label="Card Number")
    card_code = forms.CharField(max_length=20, label="Security Code")
    card_expirate_time = forms.CharField(max_length=100, label="Expiration (MM/YYYY)")

    class Meta:
        model = models.GiftCard
        exclude = ('price', )

---

以下是一个例子：

试穿Models.py

email = models.EmailField(verbose_name="E-Mail Address")
email_confirmation = models.EmailField(verbose_name="Please repeat")

---

这个答案的问题在于，它没有解释如何更改父窗体中定义的字段的标签。父窗体是重要的一部分。它对我不起作用

\uuuu init\uuuuu（）得到一个意外的关键字参数“label”

如何在django模板中使用它

email = models.EmailField(verbose_name="E-Mail Address")
email_confirmation = models.EmailField(verbose_name="Please repeat")
