json - 转换为 json 时序列化下划线/蛇形大小写

Question

使用 Node 和 Sequelize，是否可以定义一个模型，该模型使用驼峰命名法作为属性，但在转换为 json 时使用下划线/蛇形命名法？

目前；

var User = seq.define('user', {
    id: {
        type: Sequelize.INTEGER,
        primaryKey: true
    },
    shortLivedToken: {
        type: Sequelize.STRING,
        field: 'short_lived_token'
    },
    longLivedToken: {
        type: Sequelize.STRING,
        field: 'long_lived_token'
    }
}, {
    underscored: true,
    underscoredAll: true,
});

调用response.json(user)时变成

{
  "id": null,
  "shortLivedToken": "abcde",
  "longLivedToken": "fghji",
  "updated_at": "2015-11-21T18:32:20.181Z",
  "created_at": "2015-11-21T18:32:20.181Z"
}

我希望它是

{
  "id": null,
  "short_lived_token": "abcde",
  "long_lived_token": "fghij",
  "updated_at": "2015-11-21T18:32:20.181Z",
  "created_at": "2015-11-21T18:32:20.181Z"
}

有什么想法吗？

Not possible. The attribute names are used for getting values, toJSON uses methods for getting values. Overwrite toJSON or don't use camel cased attribute names.
