我有一个继承自其他 2 个表单的表单。在我的表单中，我想更改在其中一个父表单中定义的字段的标签。有谁知道如何做到这一点？

我正在尝试在我的 中执行此操作__init__，但它会引发错误，提示“'RegistrationFormTOS' 对象没有属性 'email'”。有谁知道我该怎么做？

谢谢。

这是我的表单代码：

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

你应该使用：

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

首先请注意，您应该使用 super 调用。

这是从覆盖默认字段中获取的示例：

from django.utils.translation import ugettext_lazy as _

class AuthorForm(ModelForm):
    class Meta:
        model = Author
        fields = ('name', 'title', 'birth_date')
        labels = {
            'name': _('Writer'),
        }
        help_texts = {
            'name': _('Some useful help text.'),
        }
        error_messages = {
            'name': {
                'max_length': _("This writer's name is too long."),
            },
        }

您可以label在定义表单时设置为字段的属性。

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', )

您可以通过“字段”字典访问表单中的字段：

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。（否则你不能有一个名为 'clean' 或 'is_valid' 的字段）直接在类主体中定义字段只是为了方便。

试试 Models.py

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

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")

如果所有其他解决方案都不起作用，这个对我有用（将用户类标签更改为 django contrib auth）

#in models.py

User._meta.get_field('username').verbose_name = "new name"
