Unhandled rejection TypeError: Dependency name must be given as a not empty string

Question

我在代码点击 require('./models').sequelize.sync() 时收到此错误。（models 是由运行命令 sequelize init 创建的目录）谁能给我一些提示，说明是什么导致了这个错误？

> node src/server.js

我正在使用 sequelize@3.2.0 和 HapiJS。可以找到类似的回购 here。（这个 repo 确实有效，即使 sequelize 升级到最新版本）

Answer 1

这是由我的其中一个模型文件中的格式不正确的自引用密钥引起的。

Answer 2

根据sequelize上一版本声明外键所致

根据最新版本"sequelize"：“^4.31.2”，添加外键的正确方法是-

addressId: {
    type: DataTypes.INTEGER,
    references: {
        model: 'addresses',
        key: 'id'
    }
}

我将其声明为

addressId: {
    type: DataTypes.INTEGER,
    references: 'addresses',
    referencesKey: 'id'
}
