javascript - sequelize group by fn count 变得未定义

Question

我的查询如下所示:

db.test.findAll({
  group: ['source'],
  attributes: ['source', [Sequelize.fn('COUNT', 'source'), 'count']],
  order: [
    [Sequelize.literal('count'), 'DESC']
  ]
}).then((sources) => {
  sources.forEach((info) => {
    console.log('sorce name :' + info.source + " count : " + info.count);
  })
}).catch((err) => {
  console.log(err);
})

所以，这里发生的是 info.source 名称被完美打印。但是 info.count 是 undefined 即使它显示在响应中？

Answer 1

Sequelize 正在尝试将结果映射到test 模型，使用raw: true 来防止...

db.test.findAll({
  group: ['source'],
  attributes: ['source', [Sequelize.fn('COUNT', 'source'), 'count']],
  order: [
    [Sequelize.literal('count'), 'DESC']
  ],
  raw: true, // <-- HERE
})
