Question

我正在实施一个django网站，

该网站转到hello world视图：

http://ec2-107-20-20-19.compute-1.amazonaws.com/

views.py /home/ubuntu/djangoProj/micopiloto/portfolio

    # Create your views here.
    from django.http import HttpResponse 

    def view(request):
        return HttpResponse('Hello Worlsss9d!')

但是我看不到amin网站，我看到了这个错误：unable to open database file

settings.py `/home/ubuntu/djangoProj/micopiloto`

所以我看到了创建的thadb.db 在我的项目文件夹中，

我有错误：

Exception Value:    
unable to open database file

所以我有$sudo chmod 777 thadb.db

但仍然得到同样的错误，

这是因为许可吗？我应该将文件夹设置为777？

编辑＆gt;＆GT;

根据建议的解决方案，我尝试使用chmod root作为db和根文件夹

-rwxrwxrwx 1 root     ubuntu   44032 2012-04-09 09:49 thadb.db
drwxrwxrwx 3 root   ubuntu 4096 2012-04-09 12:44 micopiloto

还是不行！ ;（

我收到此错误：

Exception Value:    
unable to open database file

那么如何让管理员秀？

如何影响安全？

谢谢！

Answer 1

这篇文章描述了您的问题的解决方案：

http://www.pantz.org/software/sqlite/unabletoopendbsqliteerror.html

解决方案是确保包含数据库文件的目录也具有允许该进程的写访问权。

此外，Django有一个针对此问题的页面。

https://code.djangoproject.com/wiki/NewbieMistakes#DjangosaysUnabletoOpenDatabaseFilewhenusingSQLite3

Answer 2

好吧，经过多次努力才能让它发挥作用，所以如果另一个菜鸟出现这个问题，这就是解决方案的一部分[使用正确的权限制作数据库的db file n文件夹]

问题是我的db在settings.py上的路径

我给了整条路径然后它起作用了;）

/home/ubuntu/djangoProj/micopiloto/

谢谢！

为我工作。尝试让www-data写入数据库目录以让sqlite创建日志文件。

django无法打开数据库文件
