我是 Django 的新手，并且已经做了几个类，一个帐户可以有多个订阅者。在 django admin 中查看订阅者时，它会正确显示订阅者与哪个帐户相关。但是，在查看帐户时，它不会显示它拥有哪些订阅者。

我看到一篇文章（How to create many-to-one relationship with django and to display it in admin interface）建议使用内联，尽管它对我不起作用。我在哪里错了？

模型.py：

from django.db import models
from django.contrib.auth.models import AbstractUser


class Account(AbstractUser):
    pass


class Subscriber(models.Model):
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100, null=True, blank=True)
    email = models.CharField(max_length=100, null=True)
    date_joined = models.DateTimeField(auto_now_add=True, null=True)
    verified = models.BooleanField(default=False)
    account = models.ForeignKey(
        Account, on_delete=models.CASCADE)

    def __str__(self):
        return self.email

    list_display = ('first_name', 'email', 'date_joined', 'verified')

管理员.py：

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from accounts import models

# does nothing
class SubscriberInline(admin.TabularInline):
    model = models.Subscriber
    extra = 1


admin.site.register(models.Account, UserAdmin)


# does noting
class AccountAdmin(admin.ModelAdmin):
    inlines = [SubscriberInline, ]
    #inlines = (SubscriberInline, )


@admin.register(models.Subscriber)
class SubscriberAdmin(admin.ModelAdmin):
    list_display = ("first_name", "email",
                    "date_joined", "verified", "account")

您没有向您的班级注册任何模型AccountAdmin，因此不会使用它。如果你想使用一些ModelAdmin你需要注册它。与其继承，不如ModelAdmin尝试继承UserAdmin并注册该类：

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from accounts import models

# does nothing
class SubscriberInline(admin.TabularInline):
    model = models.Subscriber
    extra = 1


class AccountAdmin(UserAdmin):
    inlines = [SubscriberInline]


admin.site.register(models.Account, AccountAdmin)


@admin.register(models.Subscriber)
class SubscriberAdmin(admin.ModelAdmin):
    list_display = ("first_name", "email",
                    "date_joined", "verified", "account")

注意：由于您使用的是自定义用户模型，因此您还应该在管理类中将属性form和设置add_form为自定义表单（从UserChangeForm和 UserCreationForm设置model它们的类）。Meta
