python - Django CustomUserModel 电子邮件字段区分大小写

Question

Django（3.0）自定义用户模型中的电子邮件字段区分大小写，我尝试了各种方法使其不区分大小写，但到目前为止没有成功。

代码

表格.py

class UserCreationForm(UserCreationForm):
    class Meta:
        model = User
        fields = ('first_name','last_name','username','email','password1','password2')


class UserChangeForm(UserChangeForm):
    class Meta:
        model = User
        fields = ('first_name','last_name','username','email',)

class UserUpdateForm(forms.ModelForm):
    '''
    model form are the form that work with specific user model
    '''
    class Meta:
        model = User
        fields = ('first_name','last_name','username','email',)



class ProfileUpdateForm(forms.ModelForm):
    '''
    model form are the form that work with specific user model
    '''
    class Meta:
        model = Profile
        fields = ['image']

管理器.py

class UserManager(BaseUserManager):
    def create_user(self, email, username, first_name, last_name, password=None):
        if not email:
            raise ValueError('Must have Email')
        if not username:
            raise ValueError('Must have username')
        if not first_name:
            raise ValueError('Must have first_name')
        if not last_name:
            raise ValueError('Must have last name')

        user = self.model(
            email=self.normalize_email(email),
            username=username,
            first_name=first_name,
            last_name=last_name,
        )
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, username, first_name, last_name, password=None):

        user = self.create_user(
            email=email,
            username=username,
            first_name=first_name,
            last_name=last_name,
            password=password,
        )
        user.is_active = True
        user.is_staff = True
        user.is_admin = True
        user.is_superuser = True
        user.save(using=self._db)

        return user

模型.py

class User(AbstractBaseUser):

    #   compulsory fields
    email = models.EmailField(max_length=255, unique=True)
    username = models.CharField(
        unique=True,  max_length=255,  null=True, blank=False)
    first_name = models.CharField(
        unique=False, max_length=255,  null=True, blank=False, verbose_name='First Name')
    last_name = models.CharField(
        unique=False, max_length=255,  null=True, blank=False, verbose_name='Last Name')

    date_joined = models.DateTimeField(default=timezone.now)

    is_staff = models.BooleanField(default=False)
    is_admin = models.BooleanField(default=False)
    is_superuser = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['first_name', 'last_name', 'username']

    objects = UserManager()

    def __str__(self):
        return f'{self. username}'

    def has_perm(self, perm, obj=None):
        return True

    def has_module_perms(self, app_label):
        return self.is_admin


class Profile(models.Model):
    user = models.OneToOneField(
        settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')

与 User 交互的模型有两种，一种是 is User，另一种是Profile。（Profle处理图像）

已经尝试过的事情

• 要尝试的一件非常明显的事情是在进行任何身份验证之前在 manager.py 中将电子邮件设为小写，所以我确实喜欢这个

manage.py （修改）

       user = self.model(
                email=self.normalize_email( **email.lower()** ), # <- notice change here
                username=username,
                first_name=first_name,
                last_name=last_name,
            )

        user = self.create_user(
            email=email.lower() ,  # <-- notice change here
            username=username,
            first_name=first_name,
            last_name=last_name,
            password=password,
        )

但这没有用。

• 其次是这篇文章，这是我关注的另一个 StackOverflow 帖子，但也没有用

我试图解决这个问题几个小时，想不出别的，非常感谢一些建议。
