Django表单 – 标签

我有一个从其他两种formsinheritance的forms。 在我的表单中,我想更改在其中一个父窗体中定义的字段的标签。 有谁知道这可以做到吗?

我正在尝试在我的__init__执行它,但是它会抛出一个错误,说''RegistrationFormTOS'对象没有'email'属性。 有谁知道我怎么能做到这一点?

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" 

注意首先你应该使用超级通话。

以下是覆盖默认字段的示例:

 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."), }, } 

您可以通过“字段”字段访问表单中的字段:

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

这样你就不必担心与表单类方法有名字冲突的表单字段。 (否则,你不能有一个名字为'clean'或'is_valid')直接在类体中定义字段大多只是一个方便。

定义表单时,可以将label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', ) 

它不适用于模型inheritance,但可以直接在模型中设置标签

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