Question

我有一个UserProfile模型，可以为我的用户模型添加一些内容，我想做的一件事是为用户提供唯一的电子邮件，所以我在我的UserProfile模型中添加了一个电子邮件属性，并将其设置为unique=True ：

class UserProfile(models.Model):
    user = models.OneToOneField(User, related_name="profile")
    email = models.EmailField(unique=True)
    avatar = models.ForeignKey(Avatar)
    ...

我为注册创建了一个自定义表单，以便直接向我的UserProfile添加一些信息：

class CreateUserForm(forms.Form):
    username = forms.CharField(max_length=30, label="Pseudo")
    password1 = forms.CharField(widget=forms.PasswordInput, label="Password")
    password2 = forms.CharField(widget=forms.PasswordInput, label="Confirmez pwd")
    email = forms.EmailField(widget=forms.EmailInput, label="E-mail")
    avatar = AvatarChoiceField(widget=forms.RadioSelect, queryset=Avatar.objects.all(), label="Avatar")

    def clean_username(self):
        username = self.cleaned_data.get('username')

        if User.objects.filter(username=username).exists():
            raise forms.ValidationError("This username is already used")

        return username

    def clean_password2(self):
        password1 = self.cleaned_data.get('password1')
        password2 = self.cleaned_data.get('password2')

        if password1 != password2:
            raise forms.ValidationError("Your passwords do not match")

        return password1

    def clean_email(self):
        email = self.cleaned_data.get('email')

        if UserProfile.objects.filter(email=email).exists():
            raise forms.ValidationError("This email is already used")

        return email

然后在我的views.py中，我对待我的表格：

def create_user(request):
    if request.method == 'POST':
        form = CreateUserForm(request.POST)

        if form.is_valid():
            username = form.clean_username()
            email = form.clean_email()
            password = form.clean_password2()
            username = form.cleaned_data['username']
            avatar = form.cleaned_data['avatar']

            user = User.objects.create_user(username=username, password=password)
            user.save()

            user_profile = UserProfile(user=user, email=email, avatar=avatar)
            user_profile.save()

    else:
        form = CreateUserForm()

    return render(request, 'accounts/create.html', locals())

最后，我将表单的电子邮件用于我的UserProfile模型，而不是我的用户模型。通过这种方式，我为我的用户提供了一个独特的电子邮件。它正在发挥作用。

我做得对吗还是有更好的方法来实现我想要的目标吗？

你走在正确的轨道上，唯一看起来不正确的是你不应该像这样手动调用sscanf(path.data(),"%*[D:/Resize/Resize/ScaledImages2/CamLeft_]%s", &cam_value); // ^^ The * indicates ignore the data. Don't read into any variable.方法：

clean

# These are not needed in your view method username = form.clean_username() email = form.clean_email() password = form.clean_password2()已调用它们。有关详细信息，请参阅this SO问题。

Django的。在用户模型中获取唯一电子邮件的最佳方式？
