Django通过函数注册和授权

我找不到问题的解决方案。

该站点要求用户在其他字段中注册。并通过电子邮件授权。我通过一个附加模型添加了这些字段：

class Profile(models.Model):
  user = models.OneToOneField(User, on_delete=models.CASCADE)
  phone = models.IntegerField('Телефон', null=True, blank=True)
  country = models.CharField('Страна', max_length=100, null=True, blank=True)
  city = models.CharField('Город', max_length=100, null=True, blank=True)
  adress = models.CharField('Улица и дом', max_length=300, null=True, blank=True)
  zip_code = models.IntegerField('Почтовый индекс', null=True, blank=True)
  birth_day = models.DateField('День рождения', null=True, blank=True)
  avatar = models.ImageField('Аватар', upload_to='avatar', null=True, blank=True)
  agreement = models.BooleanField('Согласие на обработку', default=True)
  comment = models.TextField('Комментарии', max_length=3000, null=True, blank=True)

  @receiver(post_save, sender=User)
  def create_user_profile(sender, instance, created, **kwargs):
    if created:
      Profile.objects.create(user=instance)

  @receiver(post_save, sender=User)
  def save_user_profile(sender, instance, **kwargs):
    instance.profile.save()

  def admin_display(self):
    return self.user.last_name + ' ' + self.user.first_name

接下来，我制作了 2 个表格在模板中显示：

class ProfileForm(forms.ModelForm):
  class Meta:
    model = Profile
    exclude = ('comment', 'register_date', 'avatar', 'password', )
    widgets = {
      'phone': forms.NumberInput(attrs={'placeholder': '9XXXXXXXXX', 'class': 'form-control', 'id': 'phone'}),
      'country': forms.TextInput(attrs={'placeholder': 'Россия', 'class': 'form-control', 'id': 'country'}),
      'city': forms.TextInput(attrs={'placeholder': 'Москва', 'class': 'form-control', 'id': 'city'}),
      'adress': forms.TextInput(attrs={'placeholder': 'Ленина 25', 'class': 'form-control', 'id': 'adress'}),
      'zip_code': forms.TextInput(attrs={'placeholder': '101000', 'class': 'form-control', 'id': 'zip_code'}),
      'agreement': forms.CheckboxInput(attrs={'class': 'form-check-input', 'id': 'flexSwitchCheckChecked'}),
      'birth_day': DateInput(attrs={'class': 'form-control', 'id': 'birth_day'}),
    }


class UserForm(forms.ModelForm):
  class Meta:
    model = User
    fields = ('first_name', 'last_name', 'email', 'password',)
    widgets = {
      'first_name': forms.TextInput(attrs={'placeholder': 'Иван', 'class': 'form-control', 'id': 'first_name'}),
      'last_name': forms.TextInput(attrs={'placeholder': 'Петров', 'class': 'form-control', 'id': 'last_name'}),
      'email': forms.EmailInput(attrs={'placeholder': 'ivan_petrov@email.ru', 'class': 'form-control', 'id': 'email'}),
      'password': forms.PasswordInput(attrs={'placeholder': 'Пароль', 'class': 'form-control', 'id': 'password'}),
    }

这是视图中的内容：

def registration(request):
  if request.method == 'POST':
    form = UserForm(request.POST)
    if form.is_valid():
      instance = form.save(commit=False)
      instance.username = request.POST['email']
      instance.set_password(request.POST['password'])
      instance.save()
      return redirect('registration')
    else:
      form = UserForm(request.POST)
      profile_form = ProfileForm(request.POST)
      context = {
        'form': form,
        'profile_form': profile_form,
      }
    return render(request, 'user_registration.html', context)
  else:
    form = UserForm()
    profile_form = ProfileForm()
    context = {
      'form': form,
      'profile_form': profile_form,
    }
    return render(request, 'user_registration.html', context)

我没有显示用户名字段。相反，我在那里添加了一封电子邮件。用户已创建。由于某种原因，只有密码没有加密。并且该用户无法登录。我收到登录名/密码匹配错误。而且我找不到登录功能的示例。请帮我解决一下这个。
