我正在尝试创建自定义用户模型,并具有诸如出生日期,当前级别和其他此类参数的参数。当我运行python manage.py createsuperuser
时,出现错误,表明这些值不能为null。我不希望超级用户帐户使用这些参数。我该怎么办?
我尝试将以下行添加到从UserAdmin类继承的类中 exclude =('date_of_birth','currentLevel','totalStars','badges')
这是模型字段
class Learner(AbstractBaseUser):
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
email = models.EmailField(max_length=255, unique=True)
date_of_birth = models.DateField(auto_now=False, auto_now_add=False)
currentLevel = models.ForeignKey(SubLevelConcepts, related_name='currentLevel', on_delete=models.CASCADE)
totalStars = models.IntegerField(default=0)
badges = models.IntegerField(default=0)
active = models.BooleanField(default=True)
staff = models.BooleanField(default=False)
superuser = models.BooleanField(default=False)
objects = LearnerManager()
这是管理类
class LearnerAdmin(UserAdmin):
add_form = LearnerCreationForm
form = LearnerChangeForm
model = Learner
exclude = ('date_of_birth', 'currentLevel', 'totalStars', 'badges')
list_display = (
'first_name',
'last_name',
'email',
'staff',
'active'
)
list_filter = (
'email',
'active'
)
fieldsets = (
(None, {'fields': ('email', 'password',)}),
('Permissions', {'fields': ('staff', 'active')}),
)
add_fieldsets = (
(None, {
'classes': ('wide',),
'fields': ('email', 'first_name', 'last_name','password1', 'passsword2', 'staff', 'active')}
)
)
search_fields = ('email',)
ordering = ('id',)
filter_horizontal = ()
这是我运行python manage.py createsuperuser
django.db.utils.IntegrityError: (1048, "Column 'currentLevel_id' cannot be null")
我希望超级用户只需输入电子邮件和密码即可完成工作。稍后再添加名字和姓氏
答案 0 :(得分:0)
在您的null=True
字段中添加default=None
和ForeignKey
,因此不是必需的,即
class Learner(AbstractBaseUser):
# ...
currentLevel = models.ForeignKey(SubLevelConcepts, null=True, related_name='currentLevel', on_delete=models.CASCADE)
您可能还想使用models.PROTECT
或models.SET_NULL
而不是models.CASCADE
-除非您确实希望在删除与用户匹配的SubLevelConcept
后删除用户帐户,那是...
您可能还需要检查blank=True
models field option FWIW。
