我正在尝试创建一个注册表格,用于注册User
和他的UserProfile
。问题是Django
说username
不可用。
django.core.exceptions.FieldError: Unknown field(s) (username) specified for Use
rProfile
我希望表单包含我想要的所有属性(均来自内置
User
和UserProfile
)。怎么办呢?我知道问题是因为我添加了
UserCreationForm.Meta.fields
,但是如何使其起作用?这似乎是一个清晰而简单的解决方案。形式如下:
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
用户配置文件模块:
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)
最佳答案
如错误所述,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括“用户”字段。相反,您将需要像使用password1 / password2一样在类级别上手动指定它们。另外,您还需要在save
方法中对它们进行处理。
与其做所有这些,不如创建一个自定义用户模型,其中包括来自User和UserProfile的字段,可能会更好。这样,您只有一个模型,所有字段将自动包含在UserCreationForm中。
