【问题描述】：

我正在使用将性别存储为 0 - 男性和 1 - 女性的数据库。

我的 forms.py 看起来像这样

class CustomUserCreationForm(UserCreationForm):
    class Meta(UserCreationForm.Meta):
        model = TbUser

    def clean_username(self):
        username = self.cleaned_data["username"]
        try:
            TbUser.objects.get(username=username)
        except TbUser.DoesNotExist:
            return username
        raise forms.ValidationError(self.error_messages['duplicate_username'])


class TbUserRegisterForm(CustomUserCreationForm):
    email = forms.EmailField()

    class Meta:
        model = TbUser
        fields = ['username', 'email', 'cellphone', 'sex', 'role', 'department', 'password1', 'password2']

Django 用户模型

class TbUser(AbstractBaseUser, PermissionsMixin):
    id = models.CharField(primary_key=True, max_length=32, default=uuid.uuid4)
    username = models.CharField(max_length=40, blank=True, null=True, unique=True, db_column='usname')
    password = models.CharField(max_length=255, blank=True, null=True, db_column='dj_psword')
    email = models.CharField(max_length=255, blank=True, null=True)
    cellphone = models.CharField(max_length=100, blank=True, null=True)
    image_id = models.CharField(max_length=40, blank=True, null=True)
    sex = models.IntegerField(blank=True, null=True)
    is_available = models.IntegerField(blank=True, null=True)
    role = models.ForeignKey(TbRole, on_delete=models.CASCADE)
    department = models.ForeignKey(TbDepartment, on_delete=models.CASCADE)


    is_superuser = models.BooleanField(default=False, blank=True, null=True, db_column='default_super')
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)

    objects = TbUserManager()

    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['email']

    class Meta:
        managed = False
        db_table = 'tb_user'

    
    def __str__(self):
        return '%s' % self.username

由于sex 是一个整数字段，UI 表单字段不是一个选择字段，而只是显示用于递增整数的箭头。有没有办法让它成为 m 将存储 0 和 f - 1 的选择字段？

【参考方案1】：

是的，您可以将此分配给choices=… parameter [Django-doc]：

SEX_CHOICES = [
    (0, 'Male')
  , (1, 'Female')
]

class TbUser(AbstractBaseUser, PermissionsMixin):
    # …
    sex = models.IntegerField(blank=True, null=True, choices=SEX_CHOICES)
    # …
