How to search an element in array using node.js in mongodb? -


in mongodb there document below,

{    "_id": objectid("57443657ee5b5ccc30c4e6f8"),    "name": "kevin",    "email": "kevinwarn@gmail.com",    "password": "$2a$13$iz0phuy6vlbf6qc9ruredrg39fw5pekkih.vcligslpzmkyveyzey",    "mobile": "9980896745",    "__v": numberint(0),    "ocassiontypes": [      {        "occasiontype": "anniversary",        "date": "2016-05-30t18:30:00.000z"      },      {        "occasiontype": "donation",        "date": "2016-07-24t18:30:00.000z"      },      {        "occasiontype": "house warming",        "date": "2016-09-21t18:30:00.000z"      }    ]  }

so have written query in nodejs search occasiontype element in ocassiontypes array below,

router.post('/find-registry', function(req, res){     var uemail = req.body.email;     var uoctype = req.body.useroccasion;     var finduserid = function(db, callback) {              var cursor =db.collection('users').find({email:uemail, ocassiontypes: {$elemmatch: {occasiontype:uoctype}}}).toarray(function(err, docs1){                 if(err){                       callback(new error("some problem"));                 } else {                     callback(null,docs1);                 }              });     };      mongoclient.connect(config.database, function(err, db) {         assert.equal(null, err);         finduserid(db, function(err,docs1) {             db.close();             if(err) return res.json({result:null})             else             return res.json({result1:docs1});         });     });                      });

using query getting 0th index element, if give 1st , 2nd element shows 0th index in output.

in front end have given input shown in picture below.

is there wrong in query? please me fix this.

your query right give matched document full array

just add projection in query 

db.collection('users').find({email:uemail, ocassiontypes: {$elemmatch: {occasiontype:uoctype}}},{email:1, ocassiontypes: {$elemmatch: {occasiontype:uoctype}}})

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
