我的本​​地 Django 在运行我们服务器上运行的 manage.py syncdb 脚本时崩溃了。

这是我在运行 python manage.py syncdb 时看到的错误消息，

OperationalError: (1193, "Unknown system variable 'TRANSACTION'")

它看起来像一个 MySQL 问题，仅供引用我在虚拟环境中安装了 MySQL-python 1.2.4 和 Django 1.5.1，我正在运行 MySQL 5.6.10 版。

这是我当前的完整虚拟环境，来自 pip list，

Django (1.5.1)
MySQL-python (1.2.4)
pymongo (2.5.2)
python-cjson (1.0.5)
wsgiref (0.1.2)

我对 Django 不是很精通，谷歌搜索也没有找到任何结果，谁能告诉我这里会发生什么？

编辑:
我在我的 settings.py 中找到了导致问题的确切行

DATABASES = {
     'default': {
        'NAME': 'test',
        'ENGINE': 'django.db.backends.mysql',
        'USER': 'redacted',
        'PASSWORD': 'redacted',
        'HOST': 'localhost'
        'OPTIONS': { "init_command": "SET storage_engine=INNODB, SESSION TRANSACTION ISOLATION LEVEL READ COMMITTED" }
    },
}

选项行在提交时解决了这个问题。我唯一能想到的是服务器运行的是 MySQL 5.5，而我在本地运行的是 5.6。

我仍然想弄清楚到底发生了什么。

最佳答案

使用

DATABASES = {

'default': {
    'NAME': 'test',
    'ENGINE': 'django.db.backends.mysql',
    'USER': 'redacted',
    'PASSWORD': 'redacted',
    'HOST': 'localhost'
    'OPTIONS': { "init_command": "SET SESSION TRANSACTION ISOLATION LEVEL READ COMMITTED"}   

},

即没有“storage_engine=INNODB”。默认使用最新版本的 MySql 引擎 INNODB。
