Django ManytoMany未在管理中显示

因为我的模型有很多关系，所以连接应该是双向的，但不是双向的

例如，在

BusinessProfile

的管理部分，我可以看到

服务

模型的名称和图像字段，因为它们处于多个关系中，但情况并非相反。我无法在管理中的

Services

model中查看

BusinessProfile

models字段

我的模型结构正确吗

我还附上了图片。

models.py

class Service(models.Model):
    name = models.CharField(max_length=50)
    image = models.ImageField(upload_to='image', blank = True)
    #business_profile = models.ManyToManyField("BusinessProfile", blank=True, related_name="business_of_services")

    def __str__(self):
        return "Service - {}".format(self.name)


class BusinessProfile(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, on_delete=models.CASCADE)
    business_name = models.CharField(max_length=100, unique =True)
    register_date = models.DateTimeField(default=timezone.now)
    pan_number = models.IntegerField(unique=True)
    pan_name = models.CharField(max_length=100)
    address = models.TextField(max_length=200)
    pincode = models.IntegerField()
    city = models.CharField(max_length=50)
    state = models.CharField(max_length=50)

    service  = models.ManyToManyField("Service", blank=True, related_name="services_of_business")
    image  = models.ManyToManyField("Service", related_name="image_of_business")

    def __str__(self):
        return "Business - {}".format(self.business_name)

如果要使用反向多对多管理，可以使用内联线。看

文档中的示例代码

from django.contrib import admin

class MembershipInline(admin.TabularInline):
    model = Group.members.through

class PersonAdmin(admin.ModelAdmin):
    inlines = [
        MembershipInline,
    ]

class GroupAdmin(admin.ModelAdmin):
    inlines = [
        MembershipInline,
    ]
    exclude = ('members',)
