python之PyDev 和 Django : PyDev breaking Django shell

我建立了一个新项目，并用简单的模型填充了它。 (基本上我在关注 tut 。)

当我在命令行上运行 python manage.py shell 时，它工作正常:

>python manage.py shell 
 
Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] on 
win32 
Type "help", "copyright", "credits" or "license" for more information. 
(InteractiveConsole) 
>>> from mysite.myapp.models import School 
>>> School.objects.all() 
[] 

效果很好。然后，我尝试在 Eclipse 中做同样的事情(使用由相同文件组成的 Django 项目。)

Right click on mysite project >> Django >> Shell with Django environment

这是 PyDev 控制台的输出:

>>> import sys; print('%s %s' % (sys.executable or sys.platform, sys.version)) 
C:\Python26\python.exe 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] 
>>>  
>>> from django.core import management;import mysite.settings as settings;management.setup_environ(settings) 
'path\\to\\mysite' 
>>> from mysite.myapp.models import School 
>>> School.objects.all() 
Traceback (most recent call last):

    cursor = self.connection.cursor()

    cursor = self._cursor()

    self.connection = Database.connect(**kwargs) 
OperationalError: unable to open database file 

我在这里做错了什么？

请您参考如下方法:

错误是关于没有打开数据库文件。所以我猜你的 settings.py 中的数据库路径是一个相对路径，PyDev 启动 shell 的当前目录与你通常使用的不同。

如果是这种情况，请将 DATABASE_NAME 设置更改为绝对路径，它应该可以工作。
