我正在实施一个django网站，
该网站转到hello world视图：
views.py /home/ubuntu/djangoProj/micopiloto/portfolio
# Create your views here.
from django.http import HttpResponse
def view(request):
return HttpResponse('Hello Worlsss9d!')
但我看不到amin网站，我看到这个错误：unable to open database file

所以我在项目文件夹中看到了创建的thadb.db，
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>>
根据建议的解决方案，我尝试了chmod root用于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
还是行不通！ （
我收到此错误：
Exception Value:
unable to open database file
那么如何让管理员秀？
谢谢！
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进程的写访问权限。
此外，Django有一个页面来解决这个问题。
好吧，经过多次努力使其工作，所以如果另一个菜鸟有这个问题，这是解决方案的一部分[使用正确的权限制作数据库的db文件n文件夹]
问题是我的db在settings.py上的路径
我给了整个路径，然后它工作;）
/home/ubuntu/djangoProj/micopiloto/
谢谢！

适合我。尝试让www-data写入数据库目录，让sqlite创建日志文件。
