如何在基本 Django 用戶模型中獲取電子郵件字段？

Question

我試圖強迫用戶在注冊時輸入他們的電子郵件。 我了解如何在 ModelForms 中使用表單字段。 但是，我無法弄清楚如何強制要求現有字段。

我有以下 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')

我正在使用以下視圖來處理我的數據。 我不確定它的相關性，但值得說的是其他字段（用戶名、密碼）正確加載錯誤。 但是，用戶模型已經根據需要設置了這些字段。

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))

我曾嘗試在 RegistrationForm 中創建一個電子郵件字段，但這似乎沒有效果。 我是否需要擴展用戶模型並覆蓋電子郵件字段？ 還有其他選擇嗎？

謝謝，

只需覆蓋__init__即可使電子郵件字段成為必需：

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

這樣，您不必完全重新定義字段，而只需更改屬性。 希望能幫到你。
