在Django项目中获取TypeError错误 [英] Getting a typeError error in django project

问题描述

我为新项目创建了一个虚拟环境，安装了django并启动了新项目。但是，每当我使用manage.py运行一行代码时，都会出现此长时间错误。

I created a virtual environment for my new project, installed django and started the new project. However, whenever i run a line of code with manage.py i get this long error.

数据库条目：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

推荐答案

它的确是N AME正在转换为pathlib.Path（ WindowsPath ）对象而不是无法在Django中以与 os.path 期望使用字符串（不能100％确定，因为没有深入研究）

It does seem NAME is being converted to pathlib.Path (WindowsPath) object instead of string which then cannot be used in Django in same way as os.path expects strings (Not 100% sure as did not investigate in depth)

因此，使用字符串强制转换

So casting in string would be appropriate

'NAME': str(os.path.join(BASE_DIR, "db.sqlite3"))
