Django 表单集标签

我有一个从其他两个表单继承的表单。在我的表单中，我希望更改在父表单之一中定义的字段的标签。有人知道怎么做吗？

我尝试在我的 __init__中执行，但是它抛出一个错误说“‘ RegistrationFormTOS’对象没有‘ email’属性”。有人知道我怎么做到的吗？

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

You access fields in a form via the 'fields' dict:

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

That's so that you don't have to worry about form fields having name clashes with the form class methods. (Otherwise you couldn't have a field named 'clean' or 'is_valid') Defining the fields directly in the class body is mostly just a convenience.

最佳答案

You should use:

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

Note first you should use the super call.

It don't work for model inheritance, but you can set the label directly in the model

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

You can set label as an attribute of field when you define form.

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', )

Here's an example taken from Overriding the default fields:

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."),
},
}

Try on Models.py

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

if all other solutions don't work, this one worked for me (to change the user class label to django contrib auth)

#in models.py


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