我在学习django REST framework，感觉 追梦人物 写的教程非常好，但是看教程却非常难受，网站时不时就504，慢的要死，所以我就把《django REST framework 教程》的网页下载了下来，上传到github方便自己以及大家学习。

已解决

运行环境: Ubuntu18.04，按照README.md 中的步骤，尝试在本地运行，在第四步迁移数据库，执行
pipenv run python manage.py migrate
命令时发生报错，错误信息是:
django.db.utils.OperationalError: unable to open database file
并且根目录下并没有像以往一样生成db.sqlite3文件，于是去查看
HelloDjango-blog-tutorial/blogproject/settings文件夹下的common.py文件，发现DATABASES设置如下:

DATABASES = {
    'default': {
        'ENGINE' 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'database', 'db.sqlite3'),
    } 

根据django官方文档:

NAME¶
默认值：（''空字符串）

要使用的数据库的名称。对于SQLite，它是数据库文件的完整路径。指定路径时，即使在Windows（例如C:/homes/user/mysite/sqlite3.db）上，也始终使用正斜杠。

'NAME'指定了db.sqlite3文件的完整路径，但是克隆下来的项目根目录中并没有database这个文件夹，因此导致报错unable to open database file,在项目根目录下手动新建database文件夹后，问题解决。

When I click the detail of the posts, the connection is failed. How can I do? Thanks!
