无论我做什么，我都无法解决错误。

这是注册视图（我在成功注册后重定向到“重定向”视图，这只是为了占位符，在模板中打印登录用户的电子邮件）

视图.py

def redirect(request):
    return render(request, 'accounts/redirect.html')

def signup(request):
    if request.method == 'POST':
        form = SignUpForm(data=request.POST)
        if form.is_valid():
            user = form.save()
            login(request, user)
            return redirect('accounts:redirect')
    else:
        form = SignUpForm()
    return render(request, 'accounts/signup.html', {'form': form})

我的 Django 应用程序中有一个 CustomUser 对象作为我的身份验证用户模型。我使用 CustomUserCreationForm 和 SignUpForm 继承了这个 CustomUserCreation 表单（您可以在下面看到 CustomUser 模型、CustomManager 以及 CustomForms。）

模型.py

class CustomUser(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField('email adress', unique=True)
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    is_exhibitor = models.BooleanField(default=False)
    date_joined = models.DateTimeField(auto_now_add=True)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

    objects = CustomUserManager()

    def __str__(self):
        return self.email

    class Meta:
        verbose_name = 'user'

管理者.py

class CustomUserManager(BaseUserManager):
    """
    Custom user model manager where email is the unique identifiers for authentication instead of usernames.
    """
    def create_user(self, email, password, **extra_fields):
        """
        Create and save a User with the given email and password.
        """
        if not email:
            raise ValueError('The email must be set')

        email = self.normalize_email(email)
        user = self.model(email=email, **extra_fields)
        user.set_password(password)
        user.save()

        return user

    def create_superuser(self, email, password, **extra_fields):
        """
        Create and save a SuperUser with the given email and password.
        """
        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)
        extra_fields.setdefault('is_active', True)

        if extra_fields.get('is_staff') is not True:
            raise ValueError('Superuser must have is_staff=True.')
        if extra_fields.get('is_superuser') is not True:
            raise ValueError('Superuser must have is_superuser=True.')

        return self.create_user(email, password, **extra_fields)

表格.py

class CustomUserCreationForm(UserCreationForm):
    class Meta:
        model = CustomUser
        fields = ('email',)


class CustomUserChangeForm(UserChangeForm):
    class Meta:
        model = CustomUser
        fields = ('email',)

class SignUpForm(CustomUserCreationForm):
    class Meta:
            model = CustomUser
            fields = ('email', 'password1', 'password2')

问题是您有一个名为的视图函数redirect(request)，它与 Django 的redirect()函数冲突。因此，将您的视图名称更改为其他名称，

def redirect_view_function(request):
    return render(request, 'accounts/redirect.html')
