Django 内联没有外键

Question

我现在出错了。这是内联错误，我试图找到解决方案，我试了一整天但都失败了。如果这个问题很简单并且重复，我很抱歉。

这是错误，当我尝试使用内联时它显示

<class 'brick.admin.AdminRoomStateInline'>: (admin.E202) 
'brick.RoomInfomation' has no ForeignKey to 'brick.RoomInfomation'

models.py

class RoomInfomation(models.Model):

    roomNum = models.PositiveSmallIntegerField(default=0, primary_key=True)
    roomFloor = models.PositiveSmallIntegerField(default=0)
    startPointX = models.PositiveSmallIntegerField(default=0)
    startPointY = models.PositiveSmallIntegerField(default=0)
    #referencing 
    userInfo_RoomReservationFK = models.ForeignKey('UserInfo', null=True, blank=True)
    compInfo_RoomInfoFK = models.ForeignKey('CompanyInfomations', on_delete=models.CASCADE)
    companyRoomTypeInfo_RoomInfoFK = models.ForeignKey('CompanyRoomTypeInfomations', on_delete=models.CASCADE)

def __unicode__(self):
    return '%s' % str(self.PositiveSmallIntegerField)

class RoomState(models.Model):
    roomReservation_roomStateFK = models.ForeignKey('RoomInfomation')
    reservationBlock = models.BooleanField(default=False)
    reservated = models.BooleanField(default=False)                                         
    reservatedDate = models.DateField(blank=True, null=True)
    reservationFirstDate = models.DateField(blank=True, null=True)
    reservationEndDate = models.DateField(blank=True, null=True)
    checkoutTime = models.DateField(blank=True, null=True)
    checkinTime = models.DateField(blank=True, null=True)

admin.py

class AdminRoomStateInline(admin.TabularInline):
    model = RoomInfomation
    extra = 8
#    list_display = [
#              'roomReservation_roomStateFK',
#              'reservationBlock',
#              'reservated',
#              'reservatedDate',#예약을 진행했던 날짜
#              'reservationFirstDate',
#              'reservationEndDate',
#              'checkoutTime',
#              'checkinTime',
#            ]
#    inlines = [AdminRoomInfomationInline,]

class AdminRoomInfomation(admin.ModelAdmin):

    fields = [
          'compInfo_RoomInfoFK',
          'companyRoomTypeInfo_RoomInfoFK',
          'userInfo_RoomReservationFK',
          'startPointX',
          'startPointY', 
          'roomNum',
          'roomFloor'
         ]
    inlines = [AdminRoomStateInline,]


#class RoomState(admin,ModelAdmin):
#admin.site.register(RoomInfomation)
#admin.site.register(RoomState, AdminRoomState)
admin.site.register(UserInfo, AdminUserInfo)   
admin.site.register(RoomInfomation, AdminRoomInfomation)
admin.site.register(RoomState)

我仔细检查可能没有尝试过，例如，当我更改内联时

class AdminRoomState

到

class AdminRoomInfomationInline

错误

<class 'brick.admin.AdminRoomStateInline'>: (admin.E202) 
'brick.RoomInfomation' has no ForeignKey to 'brick.RoomState'

Answer 1

在 AdminRoomStateInline 中，您传递的是 RoomInformation 模型，它应该是 `RoomState。

Django 内联没有外键

Django inline has no ForeignKey
