如何获得基本Django用户模型中的电子邮件字段？

Question

我试图强制用户在注册时输入他们的电子邮件。我了解如何通过ModelForms使用表单字段。但是，我无法弄清楚如何强制要求现有的字段。

我有以下的ModelForm：

class RegistrationForm(UserCreationForm): 
    """Provide a view for creating users with only the requisite fields.""" 

    class Meta: 
     model = User 
     # Note that password is taken care of for us by auth's UserCreationForm. 
     fields = ('username', 'email') 

我使用下面的视图来处理我的数据。我不确定它有多相关，但值得一提的是其他字段（用户名，密码）正确加载错误。但是，用户模型已经根据需要设置了这些字段。

def register(request): 
    """Use a RegistrationForm to render a form that can be used to register a 
    new user. If there is POST data, the user has tried to submit data. 
    Therefore, validate and either redirect (success) or reload with errors 
    (failure). Otherwise, load a blank creation form. 
    """ 
    if request.method == "POST": 
     form = RegistrationForm(request.POST) 
     if form.is_valid(): 
      form.save() 
      # @NOTE This can go in once I'm using the messages framework. 
      # messages.info(request, "Thank you for registering! You are now logged in.") 
      new_user = authenticate(username=request.POST['username'], 
       password=request.POST['password1']) 
      login(request, new_user) 
      return HttpResponseRedirect(reverse('home')) 
    else: 
     form = RegistrationForm() 
    # By now, the form is either invalid, or a blank for is rendered. If 
    # invalid, the form will sent errors to render and the old POST data. 
    return render_to_response('registration/join.html', { 'form':form }, 
     context_instance=RequestContext(request)) 

我已经尝试在RegistrationForm中创建一个电子邮件字段，但这似乎没有效果。我是否需要扩展用户模型并覆盖电子邮件字段？还有其他选择吗？

感谢，

只是覆盖__init__使电子邮件字段要求：

class RegistrationForm(UserCreationForm): 
    """Provide a view for creating users with only the requisite fields.""" 

    class Meta: 
     model = User 
     # Note that password is taken care of for us by auth's UserCreationForm. 
     fields = ('username', 'email') 

    def __init__(self, *args, **kwargs): 
     super(RegistrationForm, self).__init__(*args, **kwargs) 
     self.fields['email'].required = True 

这样，您就不必完全重新定义了现场，但只需更改属性。希望能帮助你。
