如何连接Django中的2个多对多字段

Question

我在模型中有 2 个多对多字段，我想将它们相互连接我的意思是如果我将 Admin Model 中的用户与 Counter Party 连接，我在 Counter Party 管理员中看不到

我怎样才能做到这一点？

当我试图这样做时，它只显示在 1 model

模型.py

class CustomUser(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, verbose_name='Пользователь')
    user_counter = models.ManyToManyField('CounterParty', blank=True, verbose_name='Контрагенты пользователя')

    def __str__(self):
        return f'{self.user}'


class CounterParty(models.Model):
    GUID = models.UUIDField(default=uuid.uuid4, editable=True, unique=True)
    name = models.CharField(max_length=150, verbose_name='Наименование')
    customer = models.BooleanField(default=False, verbose_name='Заказчик')
    contractor = models.BooleanField(default=False, verbose_name='Подрядчик')
    counter_user = models.ManyToManyField(User, blank=True, related_name='counter_user',
                                          verbose_name='Пользователи контрагента')

    class Meta:
        verbose_name = 'Контрагент'
        verbose_name_plural = 'Контрагенты'

    def __str__(self):
        return

管理员.py

from django.contrib import admin
from .models import CustomUser, CounterParty, ObjectList, SectionList
from authentication.models import User
from authentication.admin import UserAdmin


class CustomUserInLine(admin.StackedInline):
    model = CustomUser
    can_delete = False
    verbose_name_plural = 'Пользователи'


class CustomUserAdmin(UserAdmin):
    inlines = (CustomUserInLine,)


@admin.register(CounterParty)
class CounterPartyAdmin(admin.ModelAdmin):
    pass


admin.site.unregister(User)
admin.site.register(User, CustomUserAdmin)

用户管理员

对方管理员

您不希望 ManyToMany 有这些类型的引用。 理想情况下，您会有一个单方面的参考。

您可以像这样在管理员中进行内联：

class CustomUserInLine(admin.StackedInline):
    model = "CustomUser.user_counter.through"

以下是管理员中内联 M2M 的文档： Django 文档
