原文:我最近开始从我的一些旧代码中获取MySQL OperationalErrors,似乎无法追溯问题.由于它之前的工作,我认为它可能是一个破坏了一些东西的软件更新.我正在使用带有nginx的django runfcgi的python 2.7.这是我的原始代码:

views.py

DBNAME = "test"
DBIP = "localhost"
DBUSER = "django"
DBPASS = "password"
db = MySQLdb.connect(DBIP,DBUSER,DBPASS,DBNAME)
cursor = db.cursor()

def list(request):
    statement = "SELECT item from table where selected = 1"
    cursor.execute(statement)
    results = cursor.fetchall()

我尝试了以下内容,但它仍然无效:

views.py

class DB:
    conn = None
    DBNAME = "test"
    DBIP = "localhost"
    DBUSER = "django"
    DBPASS = "password"
def connect(self):
    self.conn = MySQLdb.connect(DBIP,DBUSER,DBPASS,DBNAME)
def cursor(self):
    try:
        return self.conn.cursor()
    except (AttributeError, MySQLdb.OperationalError):
        self.connect()
        return self.conn.cursor()

db = DB()
cursor = db.cursor() …
