django migrate报错:1005 - Can't create table xxx (errno: 150 "Foreign key constraint is inc

自从mysql升级,以及使用mariaDB以来,很多不曾更新django中model的外键,

今天,按以前的思路写完外键之后,

migrate命令报错:

1005 - Can't create table `xxxDB`.`#sql-1_407` (errno: 150 "Foreign key constraint is incorrectly formed")

很郁闷,跟踪到mysql的日志:

SHOW ENGINE INNODB STATUS; 

------------------------
LATEST FOREIGN KEY ERROR
------------------------
2019-06-06 01:52:21 0x7f27202bf700 Error in foreign key constraint of table `xxxDB`.`cmdb_jiraworkflow`:
Alter table `xxxDB`.`cmdb_jiraworkflow` with foreign key constraint failed. Referenced table `xxxDB`.`cmdb_env` not found in the data dictionary near ' FOREIGN KEY (`env_name_id`) REFERENCES `cmdb_env` (`id`)'.


Referenced table not found in the data dictionary near ' FOREIGN KEY REFERENCES .

眼睛绿了,以写django写法有错,改了N次无果。

网上查了N多方案,没有对应我这个的。

最后,想起来了MYSQL升级的事端,以前的存储引擎都是MYISAM,更改为INNODB试试?

结果,OK了~~~~

django的o数据库设置也更新如下:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'xxxDB',
        'USER': 'xx',
        'PASSWORD': 'xxx',
        'HOST': '10.xx.x.1',
        'PORT': '3306',
        'OPTIONS': {"init_command": "SET storage_engine=INNODB", }
    },
}
