Python Django用户未在管理站点中显示出生日期

我通过使用内置的注册和激活功能发送令牌激活电子邮件来注册用户。注册表单将UserCreationForm子类化，为电子邮件和出生日期验证添加额外字段。我的代码如下：

forms.py：

class UserRegisterForm(UserCreationForm):

date_of_birth = forms.DateField(widget=forms.SelectDateWidget(years=range(2017, 1900, -1)))
email = forms.EmailField(required=True)

def clean_username(self):
    username = self.cleaned_data.get('username')
    if User.objects.filter(username__iexact=username).exists():
        raise forms.ValidationError('Username already exists')
    return username

def clean_date_of_birth(self):
    '''
    Only accept users aged 13 and above
    '''
    userAge = 13
    dob = self.cleaned_data.get('date_of_birth')
    today = date.today()
    if (dob.year + userAge, dob.month, dob.day) > (today.year, today.month, today.day):
        raise forms.ValidationError('Users must be aged {} years old or above.'.format(userAge))
    return dob

def clean_email(self):
    email = self.cleaned_data.get('email')
    if User.objects.filter(email__iexact=email).exists():
        raise forms.ValidationError('A user has already registered using this email')
    return email

def clean_password2(self):
    '''
    we must ensure that both passwords are identical
    '''
    password1 = self.cleaned_data.get('password1')
    password2 = self.cleaned_data.get('password2')
    if password1 and password2 and password1 != password2:
        raise forms.ValidationError('Passwords must match')
    return password2

class Meta:
    model = User
    fields = ['username', 'email', 'date_of_birth', 'password1', 'password2']

views.py：

def register(request):
   if request.method == 'POST':
       form = UserRegisterForm(request.POST)
       if form.is_valid():
          email = form.cleaned_data.get('email')
          date_of_birth = form.cleaned_data.get('date_of_birth')
          new_user = form.save(commit=False)
          new_user.is_active = False
          new_user.save()
          current_site = get_current_site(request)
          message = render_to_string('email_activation_link.html', {
            'new_user':new_user,
            'domain':current_site.domain,
            'uid': urlsafe_base64_encode(force_bytes(new_user.pk)),
            'token': account_activation_token.make_token(new_user),
          })
          mail_subject = 'Activate your Frac account.'
          to_email = EmailMessage(mail_subject, message, to=[email])
          to_email.send()
        return render(request, 'register_confirm.html', {'form': form})
   else:
      form = UserRegisterForm()

   return render(request, 'register.html', {'form': form})


def activate(request, uidb64, token):
   try:
       uid = force_text(urlsafe_base64_decode(uidb64))
       new_user = User.objects.get(pk=uid)
   except(TypeError, ValueError, OverflowError, User.DoesNotExist):
       new_user = None
   if new_user is not None and account_activation_token.check_token(new_user, token):
      new_user.is_active = True
      new_user.save()
      return render(request, 'register_complete.html', {})
   else:
      return render(request, 'registration_incomplete.html', {})

models.py：

class UserProfile(models.Model):
   '''
   Extends the Django User model
   '''
   user = models.OneToOneField(settings.AUTH_USER_MODEL,
                            related_name='profile')
   email = models.EmailField(blank=True)
   date_of_birth = models.DateField(blank=True, null=True)
   profile_photo = models.ImageField(blank=True)
   following = models.ManyToManyField(settings.AUTH_USER_MODEL,
                                    blank=True,
                                    related_name='followed_by')

   def __str__(self):
       return 'Followers({});Following({})'.format(self.user.followed_by.all().count(),self.get_following().count())

def post_save_user_receiver(sender, instance, created, *args, **kwargs):
   '''
   Django signals to automatically create
   a user profile when a user object is created
   '''
   if created:
       new_profile, is_created = UserProfile.objects.get_or_create(user=instance)

post_save.connect(post_save_user_receiver, sender=settings.AUTH_USER_MODEL)

admin.py：

from django.contrib import admin

from .models import UserProfile

class ProfileAdmin(admin.ModelAdmin):
    list_display = ['user', 'id', 'date_of_birth', 'profile_photo', '__str__']


admin.site.register(UserProfile, ProfileAdmin)

新用户已正确注册。但是，Django管理站点的用户部分中仅显示用户名和电子邮件字段。我不明白为什么新注册用户的出生日期字段没有显示。

您没有扩展用户模型，而是添加了相关的用户配置文件。您不需要在任何地方实际创建此用户配置文件的实例或使用表单中的数据填充它们；您在视图中获得了DOB和电子邮件值，但随后继续忽略它们

您需要使用以下值创建配置文件：

   if form.is_valid():
      new_user = form.save(commit=False)
      new_user.is_active = False
      new_user.save()
      email = form.cleaned_data.get('email')
      date_of_birth = form.cleaned_data.get('date_of_birth')
      UserProfile.objects.create(user=new_user, email=email, date_of_birth=date_of_birth)

---

出生日期

字段属于

用户配置文件

模型，因此不应将其包含在用户表单的

字段中

class UserRegisterForm(UserCreationForm):
    ...

    class Meta:
        model = User
        fields = ['username', 'email']

在您的视图中，您可以获取由您的信号创建的配置文件，并设置出生日期，您可以从已清理的数据中获取该日期

   if form.is_valid():
      email = form.cleaned_data.get('email')
      date_of_birth = form.cleaned_data.get('date_of_birth')
      new_user = form.save(commit=False)
      new_user.is_active = False
      new_user.save()
      profile = new_user.profile
      profile.date_of_birth=date_of_birth
      profile.save()

请显示您的用户模型和管理员类。请正确缩进您的代码。亲爱的所有人，我包括models.py和admin.py。我按照cezar的建议格式化了代码。亲爱的Daniel，谢谢您的回复。但是，我无法理解为什么会发生此错误：唯一约束失败：accounts\u userprofile.user\u id亲爱的Alasdair，感谢您的回复。我更了解我的错误。与Daniel的类似，实现代码会导致错误：UNIQUE constraint failed:accounts_userprofile.user_idI帮不上忙，因为您没有说明是否正在使用信号创建用户配置文件，并且还没有显示完整的回溯。如果您正在使用信号创建用户配置文件，则应使用第二个代码段，并使用
profile=new\u user.userprofile
。这不会导致唯一的约束错误。我正在使用信号创建用户配置文件（edited models.py）。第二种方法是要走的路。有趣的是，虽然还没有显示出生日期，但这让我们回到了原始版本。因此，我的问题！！！！无论如何，错误出现在您提供的最后一段代码中。profile.save应该是profile.save（）。非常感谢您的见解。
