如何在.fetchAll Bookshelf js + knex js之后循环遍历行？

Question

我有一个MySQL数据库,我需要从node.js查询

我正在使用书架和knex.

我想获取表的内容 - 我已经在我的model.js文件中定义了一个表.我正在尝试这样的查询:

//select * from completedSentences;
Model.CompletedSentences.fetchAll().then(function (resData) {
        console.log(resData)
    })

我想知道如何循环resData,因为它应该是多行.

控制台的输出看起来像这样:我没有看到我可以循环的行列表..我缺少什么？

CollectionBase {
  model:
   { [Function]
     NotFoundError: [Function: ErrorCtor],
     NoRowsUpdatedError: [Function: ErrorCtor],
     NoRowsDeletedError: [Function: ErrorCtor] },
  length: 1,
  models:
   [ ModelBase {
       attributes: [Object],
       _previousAttributes: [Object],
       changed: {},
       relations: {},
       cid: 'c4',
       id: 1 } ],
  _byId:
   { '1':
      ModelBase {
        attributes: [Object],
        _previousAttributes: [Object],
        changed: {},
        relations: {},
        cid: 'c4',
        id: 1 },
     c4:
      ModelBase {
        attributes: [Object],
        _previousAttributes: [Object],
        changed: {},
        relations: {},
        cid: 'c4',
        id: 1 } },
  _knex: null,
  _events: {},
  _eventsCount: 0 }

Answer 1

我找到了答案(文档很神秘,希望这有助于其他人)

new Model.CompletedSentences().fetchAll().then(function (resData) {
        _.each(resData.models, function (model) { //I am looping over models using underscore, you can use any loop
            console.log(model.attributes)
        })

    })

Answer 2

Model.CompletedSentences.fetchAll().then(function (resData) {
        console.log(resData.serialize())
    })

输出是json格式

Answer 3

该Collection班有一组lodash方法这一点.

你可以这样使用collection.forEach:

new Model.CompletedSentences().fetchAll().then(function (completedSentences) {
        completedSentences.forEach(function (model) {
            console.log(model.attributes)
        })    
    })

查看文档,还有许多其他有用的方法Collection.
