Mongoose导入Json导出和ID

我想为单元测试导入实际数据库的固定有限子集。因此，我将带有mongo shell的数据库导出到mydata.json中。现在我想将这个JSON文件数组准确地读入我的数据库，同时保留ID

1st:我已经无法读取JSON导出，如何修复

if !db?
  mongoose.connect(configDB.url,{auth:{authdb:configDB.authdb}}, (err)->
    if (err)
      console.log(err)
  )
  db = mongoose.connection
  db.on('error', console.error.bind(console, 'connection error:'))
  db.once('open', () ->
    console.log "Database established"
    #Delete all data and seed new data
    SomeModel = require(applicationDir + 'node/models/some.model.js')
    SomeModel.remove({}, (err) ->
      console.log('collection somes removed seeding new one')
      fs.readFile(__dirname + '/../../mongo/seed-for-test/somes.json','utf-8', (err,fileData) ->
        console.log typeof fileData
        fileData = JSON.parse(fileData)
        console.log fileData.length
        # new SomeModel(fileData).save((err) ->
        #   if err?
        #     return console.log err
        #   console.log('somes saved')
        # )
      )
    )
  )

错误

string
undefined:2
{ "_id" : { "$oid" : "551d82e30287751fa2f2dfb2" }, "prooven" : true, "title" :
^
SyntaxError: Unexpected token {

第二名 如果我取消注释下半部分，它会工作吗，或者还有什么我需要做的

编辑

导出不会返回json对象的有效数组。导出时必须使用

--jsonArray

标志。

这适用于使用

--jsonArray

标志进行导出，但在我看来这是错误的。而且.json文件的格式也没有以前那么好。我需要添加一些额外的逻辑来检查是否保存了最后一个条目

ObjectId = require('mongoose').Types.ObjectId
SomeModel = require(applicationDir + 'node/models/some.model.js')

if !db?
  mongoose.connect(configDB.url,{auth:{authdb:configDB.authdb}}, (err)->
    if (err)
      console.log(err)
  )
  db = mongoose.connection
  db.on('error', console.error.bind(console, 'connection error:'))
  db.once('open', () ->
    console.log "Database established"
    #Delete all data and seed new data
    SomeModel.remove({}, (err) ->
      console.log('collection somes removed seeding new one')
      fs.readFile(__dirname + '/../../mongo/seed-for-test/somes.json','utf-8', (err,fileData) ->
        fileData = JSON.parse(fileData)
        for singleFileData in fileData
          singleFileData._id = new ObjectId(singleFileData._id.$oid)
          new SomeModel(singleFileData).save((err) ->
            if err?
              return console.log err
            console.log('somes saved')
          )
      )
    )
  )
