javascript - Static method doesn't return -


i did try create static method in collection, doesn't callback

my code is:

//db.js

var myschema = new mongoose.schema({     name: {type: string, required: true, unique: true},     userid: {type: mongoose.schema.types.objectid, ref: 'user', required: true },     });   myschema.statics.finddashboardbyuserid = function (userid, callback) {     console.log("id ===> "+userid);     this.find({ userid: mongoose.types.objectid(userid) }, 'name', callback); };  myschema.statics.findbyname = function (name, callback) {     console.log("name ===> "+name);     this.find({ name: name }, 'index', callback); };  // build myschema model var myschema = mongoose.model('myschema', myschema);

//app.js

var mydb = require('./db'); var mongoose = require('mongoose'); var myschema = mongoose.model( 'myschema' );  exports.getuserlist = function (req, res) {      myschema.findbyuserid(req.params.userid, function (err, user) {         if(!err){             console.log(user);             res.json(user);         }else{             console.log(err);             res.json({"status":"error", "error":"error"});         }     });      myschema.findbyname('foo', function (err, username) {         if(!err){             console.log(username);             res.json(username);         }else{             console.log(err);             res.json({"status":"error", "error":"error"});         }     });  };   //console id ===> 77777777ffffff0000000011 name ===> first

i haven't callback. , never have console.log in app.js, have console.log in db.js
