`settings.py`

Question

现在已经打了几个小时对我的头。

所以这就是故事，我试图在客户端的Windows机器上启动Django-1.9.7（使用Python 2.7）应用程序。我之前已成功安装它，并且自上次成功安装以来，没有对数据库表，模型或远程触摸设置的任何内容进行任何更改。

所以我复制文件，然后运行manage.py migrate以生成必要的表。但是，我收到了这个错误：

django.db.utils.OperationalError: unable to open database file

以下是相关设置：

`settings.py`

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

我可以看到db.sqlite3正确创建了它应该在哪里，但这个错误仍然存在。任何代码访问这些表的尝试都会导致错误表明表格不存在（例如auth_user）。

我已经查看了与此相关的所有SO问题并遵循了this guide，但我还没有找到解决方案。

请记住，我可以使用完全相同的文件在我自己的计算机上运行完全相同的migrate命令。

感谢任何帮助！

的修改

是的，我已尝试将NAME参数明确设置为文件的绝对目录路径（例如'C:\\webapi\\db.sqlite3'）
是的，我已经确认BASE_DIR是正确的。

Answer 1

好的，不知道为什么会这样，但是我做了这个并将它整理出来：

manage.py flush
manage.py migrate

之前我手动删除了文件（db.sqlite3），我假设它与manage.py flush相同，但也许我错了。
