Question

我正在尝试创建一个注册表单，用于注册User和他的UserProfile。问题是Django表示username不可用。

django.core.exceptions.FieldError: Unknown field(s) (username) specified for Use
rProfile

我想表单包含我想要的所有属性（包括内置User和UserProfile）。

该怎么办？我知道问题是因为我添加了UserCreationForm.Meta.fields但是如何让它工作？这似乎是一个清晰而简单的解决方案。

这是表格：

class UserProfileCreationForm(UserCreationForm):
    password1 = forms.CharField(label="Password", widget=forms.PasswordInput)
    password2 = forms.CharField(label="Password confirmation", widget=forms.PasswordInput)

    class Meta(UserCreationForm.Meta):
        model = UserProfile
        fields = UserCreationForm.Meta.fields + ('date_of_birth','telephone','IBAN',)

    def clean_password2(self):
        # Check that the two password entries match
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 and password2 and password1 != password2:
            msg = "Passwords don't match"
            raise forms.ValidationError("Password mismatch")
        return password2

    def save(self, commit=True):
        user = super(UserCreationForm, self).save(commit=False)
        user.set_password(self.cleaned_data["password1"])
        if commit:
            user.save()
        return user

USERPROFILE MODULE：

class UserProfile(models.Model):
    user = models.OneToOneField(User, related_name='user_data')
    date_of_birth = models.DateField()
    telephone = models.CharField(max_length=40)
    IBAN = models.CharField(max_length=40)
    created = models.DateTimeField(auto_now_add=True)
    modified = models.DateTimeField(auto_now=True)

    MARITAL_STATUS_CHOICES = (
        ('single', 'Single'),
        ('married', 'Married'),
        ('separated', 'Separated'),
        ('divorced', 'Divorced'),
        ('widowed', 'Widowed'),
    )
    marital_status = models.CharField(max_length=40, choices=MARITAL_STATUS_CHOICES, null=True, blank=True)

    HOW_DO_YOU_KNOW_ABOUT_US_CHOICES = (
        ('coincidence', u'It was coincidence'),
        ('relative_or_friends', 'From my relatives or friends'),
    )
    how_do_you_know_about_us = models.CharField(max_length=40, choices=HOW_DO_YOU_KNOW_ABOUT_US_CHOICES, null=True,
                                                blank=True)

    # TRANSLATOR ATTRIBUTES

    is_translator = models.BooleanField(default=False)

    language_tuples = models.ManyToManyField(LanguageTuple)

    rating = models.IntegerField(default=0)

    number_of_ratings = models.BigIntegerField(default=0)

    def __unicode__(self):
        return '{} {}'.format(self.user.first_name, self.user.last_name)

    def __str__(self):
        return '{} {}'.format(self.user.first_name, self.user.last_name)

如错误所示，fields属性只能包含表单所基于的模型中的字段，在本例中为UserProfile。您不能以这种方式包含用户字段。相反，您需要在类级别手动指定它们，就像使用password1 / password2一样。您还需要使用save方法对它们执行某些操作。

您可能会发现创建一个包含User和UserProfile字段的自定义用户模型，而不是完成所有这些操作。这样你只有一个模型，所有的字段都会自动包含在UserCreationForm中。
