Orchardcms Orchard CMS 1.4.2：自动路由错误和其他错误

我有一个新的Orchard CMS 1.4.2安装，我添加了一个自定义模块

自定义模块有3个自定义部件，它们基本上是bodypart ContentPart的副本

我对bodypart（或Orchard…）了解不多，我注意到mycustompartrecord类源自：

ContentPartVersionRecord

一个问题是我不知道为什么

另一个问题是，运行该站点时，在更新其中一个自定义“bodypart”内容部分的文本后，我会出现以下错误

该错误在日志中只出现过一次，此后似乎不会影响系统。不知道这是否与自动路由部分错误有关。

很遗憾，我无法回答您的主要问题

至于ContentPartVersionRecord：当您需要对一个部件进行版本控制时（即每次修改都保存一个新的内容副本），您需要使用这个。BodyPart是版本化内容部件的一种情况

我认为您得到的SQL异常是完全无害的，正如安装程序所期望的那样。此查询用于检查数据库是否已设置-如果设置失败，则不会设置。

谢谢，希望我能提供一些帮助。
