javascript - mongoose findall return data from a different model -
in users.js:
var mongoose = require('mongoose'); var user = mongoose.model('user', { username: { type: string, required: true, unique: true, lowercase: true, }, tasks: [{ type: mongoose.schema.types.objectid, ref: 'tasks', }], }); module.exports = user; i add newuser named user1 , save mongo.
the mongo doc looks like:
{ "_id" : objectid("574fb94f6a1e7d1826c16058"), "username" : "user1", "tasks" : [ ], "__v" : 0 } then try fetch document , works fine in handler:
in handlera.js:
var user = require('../models/users.js'); module.exports.getuser = function(req, res){ user.findone({username: "user1"}, function(err, data){ if(err){ console.log('getuser err', err); res.send('error') } else { console.log('getuser fx success = ', err, data); res.send(data) } }); }; the result of console.log:
getuser fx success = null { tasks: [], __v: 0, username: 'user1', _id: 574fb94f6a1e7d1826c16058 }
but same code fails in other handler in separate file.
in handlerb.js:
var user = require('../models/users.js'); module.exports.addstuff = function(req, res){ user.findone({username: "user1"}, function(err, data){ if(err){ console.log('addstuff err', err); res.send('error') } else { console.log('addstuff fx success =', err, data); res.send(data) } }); }; the result of console.log:
addstuff fx success null null
tried....and failed....
i tried other solution question: mongoose query return null
mongoose pluralizes model names it's running find on "blogposts" collection instead of "blogpost". said, query in mongo shell on "blogmodel" collection. in case:
var blogmodel = mongoose.model("blogmodel", ..) or pass collection name third param:
var blogmodel = mongoose.model("blogpost", schema, "blogmodel") this solution results in handlera.js returning null document handlerb.js.
thanks time. appreciated.
addendum. ran find({}) under both user , tasks models in handlerb.js returned document in both cases based on tasks model. see console.logs below user.find({}) , tasks.find({}) err null value data.
how badly have broken things? how can model.find return data not in model?
user.find({},funtion(err, data) ____________________ console.log of err data null [ { subtasks: [], team: [ [object] ], __v: 0, maintask: '1', _id: 574fce63d744cba421f750c1 }, { subtasks: [], team: [ [object] ], __v: 0, maintask: '2', _id: 574fce65d744cba421f750c2 } ] tasks.find({},function(err, data) ___________________ console.log of err data null [ { subtasks: [], team: [ [object] ], __v: 0, maintask: '1', _id: 574fce63d744cba421f750c1 }, { subtasks: [], team: [ [object] ], __v: 0, maintask: '2', _id: 574fce65d744cba421f750c2 }, ] this tasks model... tasks.js
var mongoose = require('mongoose'); var subtaskschema = new mongoose.schema({ subtask: { type: string, }, team: { type: array, 'defualt': [], }, done: { type: boolean, 'defualt': false, }, }); var tasks = mongoose.model('tasks', { maintask: { type: string, }, subtasks: { type: [subtaskschema], }, team: { type: array, 'defualt': [], }, done: { type: boolean, 'defualt': false, }, }); module.exports = tasks;
the mongoose docs suggest define model so, did try this?
var schema = new mongoose.schema({ name: 'string', size: 'string' }); var tank = mongoose.model('tank', schema);
