MongoDB can't get all the rows - node.js

Question

I've got a project using the MEAN stack and inside the Mongo DB collection I've got a collection called 'services' with the following rows (a small subset):
{ "_id" : ObjectId("55af611de2be6d817d000001"), "client" : "55a8e5fa586f94752a000002", "collaborators" : null, "date" : ISODate("2015-07-22T09:23:41.917Z"), "latestUpdateDate" : ISODate("2015-07-22T09:23:41.917Z"), "backofficeRequested" : false, "description" : "Uma descrição qq", "wasSeen" : 0, "currentStatusId" : "0", "lastStatusId" : 4, "__v" : 2, "addresses" : [ ], "dates" : [ ], "estimateDuration" : 61, "estimatePrice" : "55", "notes" : [ ], "serviceDate" : ISODate("2015-07-23T10:07:00Z"), "totalPrice" : "600", "serviceInvoiced" : "No", "evaluation" : "", "positiveFeatures" : "", "negativeFeatures" : "" }
{ "_id" : ObjectId("55afa8662c1e98c80d2fd2ff"), "client" : "55a8e5fa586f94752a000002", "estimatePrice" : "12", "estimateDuration" : NumberLong(720), "description" : "12", "serviceDate" : ISODate("1212-12-12T12:48:45Z"), "lastStatusId" : null, "currentStatusId" : "0", "collaborators" : [ { "id" : "55acb6022c1e98d05f2fd2ff" } ], "dates" : [ ], "totalPrice" : "", "backofficeRequested" : NumberLong(0), "serviceInvoiced" : "No", "evaluation" : "", "positiveFeatures" : "", "negativeFeatures" : "" }

I want to get all the rows belonging to the client with the ID "55a8e5fa586f94752a000002".
It's pretty easy to do in the mongo Shell:
db.services.find({"client":"55a8e5fa586f94752a000002"})
But I am having a hard time inside Node.js because it either returns no services at all or it ends up returning just one service.
Here's what I'm using right now:
(...)
console.log(checkDatas[0]._id);
Service.find().where('client', checkDatas[0]._id)
.exec(function(err, services)
{
console.log("output: " + services);
(...)
And finally, here's the output:
**55a8e5fa586f94752a000002**
**output**: { _id: 55aff719af19b58913000001,
client: 55a8e5fa586f94752a000002,
__v: 1,
collaborators: [ { id: '55acb6022c1e98d05f2fd2ff' } ],
notes: [],
dates: [],
addresses: [],
date: Wed Jul 22 2015 22:03:37 GMT+0200 (CEST),
latestUpdateDate: Wed Jul 22 2015 22:03:37 GMT+0200 (CEST),
backofficeRequested: false,
totalPrice: null,
estimatePrice: null,
estimateDuration: null,
description: '',
serviceDate: null,
wasSeen: 0,
currentStatusId: 3,
lastStatusId: 1 }
It's as if I were using findOne but I'm not.
On top of that, yesterday I had a .sort() method also in that query and things worked fine after commenting it but today the problem's back.
Do MongoDB / Node have some sort of caching system I'm not aware of?
Thanks
EDIT:
Running
Service.find({'client': checkDatas[0]._id})
yields the same result

Answer 1

It looks like you're mixing ObjectId's and strings, which are two different things.
Your Mongoose query is looking for an ObjectId:
Service.find().where('client', checkDatas[0]._id)
Quick tip: you can distinguish both types in the output:
// ObjectId, because it doesn't have quotes around it
client: 55a8e5fa586f94752a000002
// String
collaborators: [ { id: '55acb6022c1e98d05f2fd2ff' } ]
Your MongoDB shell query is looking for a string:
db.services.find({"client":"55a8e5fa586f94752a000002"})
The subset you're posting shows only strings, but I think that your database may actually contain both types. You can check and see if this works better:
Service.find().or([
{ client : checkDatas[0]._id },
{ client : String(checkDatas[0]._id) }
])...
Obviously this isn't ideal, you should consider normalizing your database if both types are mixed.
EDIT: the or query probably won't work when using Mongoose, since it will cast both clauses to the type defined in the schema. You can still check from the Mongo shell:
db.services.find({ $or : [
{ client : "55a8e5fa586f94752a000002" },
{ client : ObjectId("55a8e5fa586f94752a000002") }
]})
