如果在使用Django Admin后台添加用户时出现报错：
这时候需要在setting文件的databases中添加以下代码取消外键检查
2
完整的就是：
(1452, 'Cannot add or update a child row: a foreign key constraint fails (`mxproject`.`django_admin_log`, CONSTRAINT `django_admin_log_user_id_c564eba6_fk_auth_user_id` FOREIGN KEY (`user_id`) REFERENCES `auth_user` (`id`))')1
这时候需要在setting文件的databases中添加以下代码取消外键检查
'OPTIONS':{
"init_command":"SET foreign_key_checks = 0;",12
完整的就是：
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'mxproject',
'USER':'root',
'PASSWORD':'123456',
'HOST':'127.0.0.1',
'PORT':'3306',
'OPTIONS':{
"init_command":"SET foreign_key_checks = 0;",
}
}
