Sails REST API和MySQL:TypeError:Model.create(...)。meta不是函数

时间:2018-04-06 10:04:16

标签: javascript mysql nginx sails.js postman

我正在尝试在Ubuntu 16.04数字海洋VPS上设置REST API。我遇到了这个错误' TypeError:Model.create(...)。meta不是函数'。在检查堆栈跟踪(下面发布)之后,该功能实际上就在那里。

需要注意几点:

1)我已经成功地做了一个帆升降机'命令确实创建了' testauthdb'及其相关的架构(如下所示)

2)使用邮递员(如下所示),我能够成功点击远程服务器上的API,但是它返回了500错误的堆栈跟踪(如下所示)。

3)我已经尝试了几种方法来更新所有软件包(@beta,@ rootst),npm缓存清除,重新安装node_modules,nginx服务器重启,完全删除和重新安装项目,帆船升级命令等

4)https://github.com/balderdashy/sails/issues/4177,是一个类似的问题,但他们使用的是mongodb和mongoose。我尝试使用sails-mysql @ beta和sails-mysql @ latest,没有运气。

5)编译器没有捕获语法错误,因此您可能会在本文档中看到任何可能出现翻译问题的小错误。我认为唯一真正的错误是标题/堆栈跟踪中发布的错误。

任何指导都会非常感激,我花了很多时间试图解决这个问题。
