Question

我创建了两个自定义模型：Picture和Album

我已将它们迁移到数据库中，并且数据库中都存在这两个表

在管理员中，我想创建一个自定义管理面板，所以在 admin.py 我有

#admin.py
from django.contrib import admin
from testrest.models import Picture, Album

class AlbumAdmin(admin.ModelAdmin):
    fields = ['album_name']
admin.site.register(Album, AlbumAdmin)

我的 models.py 文件：

#models.py
from django.db import models

class Album(models.Model):
    album_name = models.CharField(max_length=30)
    def __str__(self):
        return self.album_name

class Picture(models.Model):
    file_name = models.CharField(max_length=30)
    google_hash = models.CharField(max_length=100)
    date_added = models.DateField()
    albums = models.ManyToManyField(Album)

    def __str__(self):
        return self.file_name
    class Meta:
        ordering = ('date_added',)

我得到的错误：

解决了问题。它以某种方式连接到一个不同的数据库，有一个Gunicorn的幽灵会话在后台运行，在杀死进程并重启Gunicorn后问题得到解决

管理页面无法显示自定义模型
