Django表单 - 标签 [英] Django form - set label

问题描述

我有一个继承自其他表格的表单。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。有没有人知道如何做到这一点？

我试图在我的 __ init __ 抛出一个错误，说'RegistrationFormTOS'对象没有属性'email'。有没有人知道我可以这样做？

谢谢。

这是我的表单代码：

从django导入表单
从django.utils.translation导入ugettext_lazy作为_ 
从registration.forms导入RegistrationFormUniqueEmail 
 from registration.forms import RegistrationFormTermsOfService 
 
 attrs_dict = {'class'：'required'} 
 
 class RegistrationFormTOS（RegistrationFormUniqueEmail，RegistrationFormTermsOfService）：
 
RegistrationForm的子类，它添加了一个必需的复选框
来同意一个网站的服务条款
 

 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 =新电子邮件标签
 super（RegistrationFormTOS，self）.__ init __（* args，** kwargs）
 
 def clean_email2 （自）：

验证输入到两个电子邮件字段
中的值是否匹配。 

如果self.cleaned_data中的email和self.cleaned_data中的email2：
如果self.cleaned_data ['email']！= self.cleaned_data ['email2' ]：
 raise forms.ValidationError（_（你必须每次输入相同的电子邮件））
 return self.cleaned_data 
  

解决方案

您应该使用

  def __init __（self，* args，** kwargs）：
 super（RegistrationFormTOS，self）.__ init __（* args，** kwargs）
 self.fields ['email']。label =新电子邮件标签
  

首先应该使用超级电话。

I have a form that inherits from 2 other forms. In my form, I want to change the label of a field that was defined in one of the parent forms. Does anyone know how this can be done?

I'm trying to do it in my __init__, but it throws an error saying that "'RegistrationFormTOS' object has no attribute 'email'". Does anyone know how I can do this?

Thanks.

Here is my form code:

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

解决方案

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.
