推荐答案

在 INSTALLED_APPS 内部，您应该这样声明您的 posts :'posts.apps.PostsConfig'要了解原因，请查看项目文件夹中的文件 apps.py ；它应该看起来像这样:

Inside INSTALLED_APPS you should declare your posts like that: 'posts.apps.PostsConfig' To understand why, take a look at file apps.py from your project folder; it should look like that:

from django.apps import AppConfig


class PostsConfig(AppConfig):
    name = 'posts'
