mongodb - Mongoose Import Json Export with IDs -
i want import unit tests fixed limited subset of actual database. exported database mongo shell mydata.json. want read array of json files db, keeping ids.
1st: fail on reading json export, how fix this?
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 data , 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') # ) ) ) ) error
string undefined:2 { "_id" : { "$oid" : "551d82e30287751fa2f2dfb2" }, "prooven" : true, "title" : ^ syntaxerror: unexpected token { @ object.parse (native) @ /users/masterg/desktop/projekte/lek/specs/backend/mongo.service.spec.js:37:27 @ fs.js:336:14 @ /users/masterg/desktop/projekte/lek/node_modules/wiredep/node_modules/bower-config/node_modules/graceful-fs/graceful-fs.js:104:5 @ fsreqwrap.oncomplete (fs.js:99:15) 2nd if uncomment lower part work or there else need do.
edit
the export not give valid array of json objects. --jsonarray flag has used when exporting.
this works exporting flag --jsonarray looks wrong me. .json file not formated nicely before. , need add logic check if last entry saved.
objectid = require('mongoose').types.objectid somemodel = require(applicationdir + 'node/models/some.model.js') if !db? mongoose.connect(configdb.url,{auth:{authdb:configdb.authdb}}, (err)-> if (err) console.log(err) ) db = mongoose.connection db.on('error', console.error.bind(console, 'connection error:')) db.once('open', () -> console.log "database established" #delete data , seed new data somemodel.remove({}, (err) -> console.log('collection somes removed seeding new one') fs.readfile(__dirname + '/../../mongo/seed-for-test/somes.json','utf-8', (err,filedata) -> filedata = json.parse(filedata) singlefiledata in filedata singlefiledata._id = new objectid(singlefiledata._id.$oid) new somemodel(singlefiledata).save((err) -> if err? return console.log err console.log('somes saved') ) ) ) )
