我刚刚在ubuntu 14.04服务器上使用apache部署了我的django站点。 正在访问该网站。但是当我作为用户注册时，它会创建用户，但无法创建与myuser一对一关系的用户配置文件。此外，我正在使用自定义用户模型。它在注册时抛出的错误是：
Cannot add or update a child row: a foreign key constraint fails (`ilog_prod_db`.`myuserprofile_myuserprofile`, CONSTRAINT `myuserprofile_myuserp_myuser_id_6ad6f704425ed359_fk_auth_user_id` FOREIGN KEY (`myuser_id`) REFERENCES `auth_user` (`id`))
关键是，在我的开发机器（windows7）上，网站使用相同的代码完美运行。此外，数据库的设置完全相同，即在两个地方我都使用InnoDB作为数据库的数据库引擎。
可能是什么问题。任何指针将不胜感激。感谢。

从问题的评论来看，您的django模型和数据库架构看起来不同步。如果可以，只需删除数据库并重新创建即可。如果你有重要数据......
首先备份生产数据库
根据您使用的django版本，数据库同步的行为会有所不同。
python manage.py syncdb命令可用于向数据库添加任何缺少的架构信息。如果您的问题源于您已向模型添加新表或字段/已删除约束的事实，则可能会修复架构。
它不会删除任何旧字段或迁移任何数据，因此您很可能需要在之后进行一些手动编辑。
1.7引入了更加智能的新python manage.py migrate（Docs）命令。随着模型的更改，将创建迁移。当旧数据库需要与新模型联机时，迁移将应用于数据库。
这更加灵活，允许根据需要升级/降级数据库版本。
缺点是您需要随时进行迁移（或之后手动创建）。有关详细信息，请参阅文档
在任何一种情况下，如果模型太远不同步或者您没有适当的迁移，您将需要做一些手动工作以使数据进入django所需的状态。
