如何在 django 中使用管理模型作为外键？

Question

I try to develop a relationship as One admin can add one or many subscription plans.

I try this but not worked

from django.db import models
from django.contrib import admin

class SubscriptionPlansModel(models.Model):
    title = models.CharField(max_length=50)
    price = models.IntegerField()
    duraion = models.IntegerField()
    admin = models.ForeignKey(admin,on_delete=models.CASCADE)

Answer 1

您实际上与模块而不是数据库模型建立了 ForeignKey 关系

Answer 2

Just create "Admin" class in models file. Then, use it as foreign key.

Eg

class Admin(admin.ModelAdmin):
    pass

class SubscriptionPlansModel(models.Model):
    title = models.CharField(max_length=50)
    price = models.IntegerField()
    duraion = models.IntegerField()
    admin = models.ForeignKey(admin,on_delete=models.CASCADE)
