接口错误 (0, '')

问题描述

我使用 Django 构建了一个站点，但在尝试执行查询时收到了这个烦人的错误.

I have built a site using Django and I am receiving this annoying error when I am trying to execute a query.

如果我重新启动 Apache 服务器，错误会在短时间内消失.

If I restart the Apache server, the error will go away for a short time.

Traceback:
File "/usr/local/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
100.                     response = callback(request, *callback_args, **callback_kwargs)

Exception Type: InterfaceError at /blablabla/
Exception Value: (0, '')

推荐答案

这是由全局游标引起的.尝试在需要原始查询的每个方法中创建和关闭游标.

This is caused by a global cursor. Try creating and closing the cursor within each method a raw query is needed.

cursor = connection.cursor()
cursor.execute(query)
cursor.close()
