angularjs - Aggregation does not working in Mongoose with Match and Group -


i'm coding application using angularjs, nodejs , mongoose. now, i'm doing chart , need return data passsing parameters. aggregation not work. have query working in mongodb:

  
var user = db.getcollection('users').find( {profile: "supervisor"},{_id: 1}).map(function(u){return u._id;} )  db.getcollection("visitas").aggregate(     { '$match':      { createdat:        { '$gte': isodate('2015-01-10t00:00:00.000z'),          '$lt': isodate('2015-07-01t00:00:00.000z') } } }, { '$group':      { _id: { usuario: user, dia: [object] },       visitas: { '$sum': 1 } } } )

when try run same query in application using mongoose, query not work. problem i've seen comma between match , group disapearing. when try search group or match, query works. can me? application code:

     .then(function (listausuarios){            var argsvisit;           console.log({ $match : { "createdat" : { $gte: "2015-01-10t00:00:00.000z", $lt: "2015-07-01t00:00:00.000z"  }} },                   { $group : { _id : { "usuario" : listausuarios , "dia" : { $dayofmonth : "$createdat" } }, "visitas" : { $sum : 1 } } });            visita.aggregate({ $match : { "createdat" : { $gte: "2015-01-10t00:00:00.000z", $lt: "2015-07-01t00:00:00.000z"  }} },                   { $group : { _id : { "usuario" : listausuarios , "dia" : { $dayofmonth : "$createdat" } }, "visitas" : { $sum : 1 } } })             .exec(function (err, results) {                     if (err) {                         console.log("erro!!!");                         deferreddados.reject({                             error: 500,                             message: 'erro buscando visita, erro: '+err                         });                     } else {                         if (!results || results.length == 0) {                             console.log("sem retorno!!!");                             deferreddados.resolve( [0,0,0,0,0,0,0] ); //tudo zerado poruqe não há retorno.                             //deferreddados.resolve(0);                              deferreddados.reject({                                 error: 500,                                 message: 'erro buscando visitas, não achou resultados'                              });                         } else {                             console.log("dados"+results);                             deferreddados.resolve( results );                             //deferreddados.resolve( results.data] );                         }                      }                  });           return deferreddados.promise;              })

solved!!!

a member of team found error! \o/ maybe can have same problem.

to solve, have convert date, in string, date type.

the solved code below:

.then(function (listausuarios){        var argsvisit;         if (tipovisita == 'n'){             argsvisit = {'user' : { "$in" :listausuarios }, 'tipo' : { "$in" : ["2001","2002"] }, "createdat": {"$gte": datainicial, "$lt": datafinal }};         } else if (tipovisita == 'r'){             argsvisit = {'user' : { "$in" :listausuarios }, 'tipo' : { "$in" : ["2005"] }, "createdat": {"$gte": datainicial, "$lt": datafinal }};         } else if (tipovisita == 'i'){             argsvisit = {'user' : { "$in" :listausuarios }, 'tipo' : { "$in" : ["2003"] }, "createdat": {"$gte": datainicial, "$lt": datafinal }};         }          var initdate = new date('2015-04-02t00:00:00.000z');         var enddate = new date('2015-05-09t00:00:00.000z');         argsmatch = [{ $match : { "createdat" : { $gte: initdate, $lt: enddate  }} },                    { $group : { _id : { "usuario" : listausuarios , "dia" : { $dayofmonth : "$createdat" } },  "visitas" : {$sum : { $cond: [ {$or : [ { $eq: [ "$tipo", "2001"] },{ $eq: [ "$tipo","2002"] }] },1,0 ]}}}                     }]        visita.aggregate(argsmatch)         .exec(function (err, results) {                 if (err) {                     console.log("erro!!!");                     deferreddados.reject({                         error: 500,                         message: 'erro buscando visita, erro: '+err                     });                 } else {                     if (!results || results.length == 0) {                         console.log("sem retorno!!!");                         deferreddados.resolve( [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] ); //tudo zerado poruqe não há retorno.                         //deferreddados.resolve(0);                          deferreddados.reject({                             error: 500,                             message: 'erro buscando visitas, não achou resultados'                          });                     } else {                         deferreddados.resolve( results );                     }                  }              });       return deferreddados.promise;          })   .then(function(dados) {         res.json(dados);      })    .catch(function(fallback) {     console.log('erro no retorno dos usuarios!!!');     console.log(fallback);   });

i hope can someone.
