javascript - mysql 上的 sails v10.0 遇到未定义的 'schema'

Question

我正在尝试使用 sails-mysql 适配器 0.10.6 的 sails js 版本 0.10.0

我创建了两个模型:

Customer.js

module.exports = {

  connection: 'someMysqlServer',

  attributes: {
    name: {
        type: 'string'
    },

    store: {
        model: 'Store'
    }
  }
};

和Store.js

module.exports = {

  connection: 'someMysqlServer',

  attributes: {
    name: {
        type: 'string'
    },

    customers: {
        model: 'Customer',
        required: false
    }
  }
};

当我第一次运行该应用程序时，一切都很好，我可以看到它在我的数据库上创建了两个表。但是，当我尝试重新启动应用程序时，我收到此错误:

TypeError: Cannot read property 'schema' of undefined

    at Socket.<anonymous> (C:\fray\NodeJs\testingsails10_2\test1001\node_modules
\sails-mysql\node_modules\mysql\lib\Connection.js:75:28)

如果我删除表并重新启动应用程序，它将能够运行并重新创建表，但当我到达此 Controller 时不会进一步。

module.exports = {
    add: function(req, res){
        var store = {
            name: 'strore2'
        }
        Store.create(store).exec(function(err, result){
            Customer.create({name: 'customer1', store: result.id}).exec(function (err1, result1){
                return res.json({created: result1, error: err1});   
            });
        });

    }

};

并且会抛出这个错误:

这似乎是一个损坏的依赖关系问题。尝试:

rm -rf node_modules
npm cache clear
npm install

要重新安装所有依赖项，请尝试sails lift。

此时，您将在项目中本地安装 Sails，并且 sails lift 将使用该副本。要对您的 global sails 安装执行类似的操作，请执行以下操作:

sudo npm uninstall -g sails
npm cache clear
sudo npm install -g sails

然后在您的项目中添加rm -rf node_modules/sails，以便sails lift 将使用全局安装。
