tools工具运行报错
看视频import_data的代码，自己也写了一个import_data工具自动把文章导入数据库，但是好像导入models模块出问题了
下面是我的代码：
import os import sys sys.path.append(r'E:\Python\Pycharm\django_introduction') from blog.models import Article
import_data.py 在tools目录下，tools和templates同级（models.py在templates下）
报错提示是：
Traceback (most recent call last):
File "E:/Python/Pycharm/django_introduction/tools/import_data.py", line 5, in <module>
from blog.models import Article
File "E:\Python\Pycharm\django_introduction\blog\models.py", line 5, in <module>
class Article(models.Model):
File "D:\Python\Python37-32\lib\site-packages\django\db\models\base.py", line 100, in __new__
app_config = apps.get_containing_app_config(module)
File "D:\Python\Python37-32\lib\site-packages\django\apps\registry.py", line 244, in get_containing_app_config
self.check_apps_ready()
File "D:\Python\Python37-32\lib\site-packages\django\apps\registry.py", line 127, in check_apps_ready
raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.麻烦老师帮忙看一下是怎么回事，嘻嘻嘻
