1452, 'Cannot add or update a child row: a foreign key constraint fails
作者:互联网
(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`))')
这时候需要在setting文件的databases中添加以下代码取消外键检查
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'zhq2', 'USER': 'root', 'PASSWORD': '211314', 'HOST': '127.0.0.1', 'PORT': 3306, # 取消外键的检查(admin后台添加数据会报错) 'OPTIONS': { "init_command": "SET foreign_key_checks = 0;", } } }
