node.js - mongoose query not working -


i trying run query in mongodb using mongoose :

mongoosemodel.find().where(query).exec(function (err, data) {

});

and value of query :

{ plate: 'bcf 5579', fuel_level: { $lte: 20 }}

in mongodb log, the query going empty ({}).

if replace query actual value this:

mongoosemodel.find().where({ plate: 'bcf 5579', fuel_level: { $lte: 20 }}).exec(function (err, data) {

});

it work. what's wrong first option?

here full code :

this.findallbycondition = function (query, options, callback) {             locallogger.debug('findallbycondition');             try {                  var sortby = "_id";  // default sort order                  var pagingoptions = {                     skip: 0,                     limit: 30                 };                  if (options && options.limit) {                     pagingoptions.limit = options.limit;                 }                 if (options && options.skip) {                     pagingoptions.skip = options.skip;                 }                  if (options && options.sortby) {                     sortby = options.sortby;                 }                  if (options && options.sortorder && options.sortorder === "desc") {                     sortby = "-" + sortby;                 }                   //{ plate: 'bcf 5579', fuel_level: { $lte: 20 }};                  //query1 = query;                  //query = req.query['q'];                  //var query1 = { plate: 'bcf 5579', fuel_level: { $lte: 20 }}                   var totalrecords = null;                 var results = null;                 async.parallel(                     [                         function (callback) {                             mongoosemodel.find(query).skip(pagingoptions.skip).limit(pagingoptions.limit).sort("field " + sortby).exec(function (err, data) {                                 if (err) {                                     callback(err);                                 }                                 else {                                     results = data;                                     callback();                                 }                             });                         },                         function (callback) {                             mongoosemodel.count(query, function (err, count) {                                 if (err) {                                     callback(err);                                 }                                 else {                                     totalrecords = count;                                     callback();                                 }                             });                         }                     ],                     function (err) {                         callback(err, results, totalrecords);                     }                 );             } catch (exception) {                 locallogger.error('exception while trying findone ' + exception.message + " stack:" + exception.stack);                 callback(exception, null);             }          },

java - How to specify maven bin in eclipse maven plugin? -

i have eclipse maven plugin coming on centos. how can execute maven command on linx like: mvn clean package [abigail@localhost ~]$ mvn bash: mvn: command not found how should specify path executable of maven plugin in eclipse? or have install maven seperately？ thanks. eclipse (m2e) have bundled central parts of maven inside eclipse plugin, why not detected, , not usable. investigation find correct way bootstrap it, have create launcher file manually. if want run maven outside of eclipse, far better off standalone version of maven. mvn command bootstrap maven runtime system correctly, , secondly, able use advice concerning use of maven. maven binaries quite stable, wouldn't need upgrade upgrade eclipse. you can subsequently switch eclipse use external installation if prefer.
