当我尝试在django中使用内置的admin将记录添加到数据库时，出现了这样的错误。无法理解问题所在，请帮助我了解发生了什么。

在models.py中有一个类可以容纳其他应用程序中的用户，其中有两个ImageField（）和一个布尔值。

Answer 1

MEDIA_ROOT = [
    os.path.join(BASE_DIR, 'media')
]

settings.py中的一个问题，我想在django 2.1中路径已更改，因此我遵循了过时的教程。

解决方案：默认情况下，删除MEDIA_ROOT属性是一个媒体文件夹。或设置

 MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

没有列表
