postgres / bookshelf fetchAll（）withRelated（获得多个关系）

Question

我试图做一个相当复杂（至少对我而言）的API请求，涉及获取一系列报告。报表对象本身具有嵌套对象，因此我试图同时提取相关数据。报告对象如下所示：

reports: { loading: false, error: null, data: [{id:'', date:'', 
student_id:'', 
feeding:[],diapering:[], nap:[], meds:[], playTime:[], comments:[], 
supplies:[]}] } 

我已经找到了如何使用多个相关表格获取一份报告，但我还没有找到获取报告数组的语法，每种报告都有自己的相关数据。

这就是我现在所拥有的：

exports.getReport = (date) => {
  console.log(id)
  return Reports.where(date)
        .fetchAll({
              withRelated: ['feeding', 'comment', 'diapering', 'nap', 'meds', 'playTime', 'supplies']
        })
        .then(report => {
              const meds = report.related('meds')
              const nap = report.related('nap')
              const feeding = report.related('feeding')
              const diapering = report.related('diapering')
              const supplies = report.related('supplies')
              const playTime = report.related('playTime')
              const comm = report.related('comment')

              const medsList = meds.map(med => {
                    return med.attributes
              })
              const napList = nap.map(n => {
                    return n.attributes
              })
              const feedingList = feeding.map(feed => {
                    return feed.attributes
              })
              console.log(feedingList)
              const diaperList = diapering.map(diaper => {
                    return diaper.attributes
              })
              const suppliesList = supplies.map(supply => {
                    return supply.attributes
              })
              const playTimeList = playTime.map(play => {
                    return play.attributes
              })
              const commentList = comm.map(com => {
                    return com.attributes
              })
              return reports
              const reports = report.models.map(rep => {
                    return rep.attributes
              })
              return [feedingList, commentList, napList, playTimeList, 
                      suppliesList, diaperList, medsList, reports]
        })
        .catch(err => {
              console.log(err)
        })
   }

此语法适用于

  

.fetch（）

，但没有

  

使用fetchall（）

我得到了

  

report.related不是函数错误
