未处理的拒绝类型错误：依赖名称必须作为非空字符串给出

Question

代码命中时出现此错误require('./models').sequelize.sync()。（models是通过运行命令创建的目录sequelize init）谁能给我一些有关导致此错误的提示？

我正在sequelize@3.2.0与HapiJS. 可以在此处找到类似的存储库。（这个 repo 确实有效，即使sequelize升级到最新版本）

Answer 1

这是由于根据之前版本的 sequelize 声明了外键。

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'
    }
}

我宣布它为

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

Answer 2

这是由我的模型文件之一中的不正确的自引用键引起的。
