How to print Mongoose object properties with console.log?

These are the schema from mongoose subdocuments example.
let classTypeSchema = new mongoose.Schema({
name: {
type: String,
required: true
},
abilities: {
type: Array,
default: []
},
skills: {
type: Array,
default: []
}
});
let heroSchema = new mongoose.Schema({
name: {
type: String,
required: true,
trim: true,
minlength: 3,
maxlength: 24
},
classType: [classTypeSchema],
level: {
type: Number,
default: 1
},
currency: {
type: Number,
default: 0
}
});
I tried this way
Hero = mongoose.model('Hero',heroSchema);
console.log(typeof Hero);
console.log(JSON.stringify(Hero, null, 4));
Output
function
undefined
Console.dir gives very detailed output.I am interested only in schemas part
subpaths: {
'classType.name': [SchemaString],
'classType.abilities': [SchemaArray],
'classType.skills': [SchemaArray],
'classType._id': [ObjectId],
'classType.abilities.$': [Mixed],
'classType.skills.$': [Mixed]
},
Is there any other way to print Mongoose properties and methods?

How to using "find()" with populate field in mongoose?

I have 2 collection in same db. I need to using find() to select only "Events" that have "team" equal "team1"
Thank you very much.
I have try to find by population field but it doesn't work.
This is my Event schema
const Event = mongoose.model('Event', new mongoose.Schema({
title: {
type: String,
required: true,
min: 3
},
eventType: {
type: String,
lowercase: true
},
date: {
type: Date,
default: Date.now()
},
venue: String,
country: String,
callLog: {
type: String,
max: 1000
},
eventImgUrl: [String],
editedBy : {
type: mongoose.Schema.Types.ObjectId,
ref: 'User'
},
timestamp: {
type: String,
default: Date.now()
}
}));
This is my User schema
const User = mongoose.model('User', new mongoose.Schema({
username: {
type: String,
required: true,
min: 3,
lowercase: true
},
name: String,
email: String,
team: String,
role: {
type: String,
enum: ['admin', 'creator', 'viewer']
}
}));
This is my Controller
const events = await Event.find()
.populate({ path: 'editedBy', select: ['name', 'team']});
res.send(events);

To find all Events that have a team of "team1":
const team1Events = await Event.find({ team: "team1" });

select just specifies the fields returned. You need to use populate match:
await Event.find()
.populate({ path: 'editedBy', match: { yourField: 'yourmatch' }});

ExpressJS - duplicate key error collection

I have problem with this error when I am creating a new event with category which exists in my database, for example I created an event with category "javascript" and save it to db, and then i tried to create a new event with categories "javascript, html, css" and then i got this error duplicate key error collection
So my schema for event is this:
const EventSchema = new Schema({
title: {
type: String,
required: true,
min: 3,
max: 100
},
featuredImage: {
type: Object,
},
from: {
type: Date,
required: true
},
to: {
type: Date,
required: true
},
location: {
name: {
type: String
},
address: {
type: Object
}
},
description: {
type: String
},
categories: {
type: Array,
trim: true
},
featured: {
type: Boolean
},
created_by: {
type: Schema.Types.ObjectId,
ref: 'User'
},
slug: {
type: String,
default: null
},
registration: {
type: Boolean
},
tickets: [],
allday: {
type: Boolean
},
speakers: [{
type: Schema.Types.ObjectId,
ref: 'User'
}],
attendees: [{
type: Schema.Types.ObjectId,
ref: 'User'
}],
comments: [CommentSchema]
}, {
timestamps: true,
usePushEach: true
});
So basically sending array of strings and i got this error.

You probably have some index defined on categories with the unique flag.
You can list the existing indexes with db.events.getIndexes().
You could drop and recreate the culprit (be careful):
> db.events.dropIndex({categories:1})
> db.events.ensureIndex({categories:1},{sparse:true})

Mongodb in array query wont get any result

Okay, so im getting all convensations with the following query:
return convensations.findOne({}).lean().then(function (convensations) {
console.log(convensations);
});
that would results in the following:
{ _id: 598dd4458b08b727dc53d4a6,
initiateduser: 'spillinfo',
gang: false,
global: false,
members: [ 'spillinfo', '59312d2b329b7535b07e273c' ],
name: 'no name',
__v: 0 }
thats totally fine, but when i do
var userid = "59312d2b329b7535b07e273c";
return convensations.find({members: userid}).lean().then(function (convensations) {
console.log(convensations);
});
it wont get me any results, why is that?
what im i doing wrong to check if the userid is within the members array?
UPDATE EDIT:
DB schema:
new Schema({
initiateduser : String,
name: {type:String, default: 'no name'},
members: { type: Array, default: []},
time: Number,
global: { type: Boolean, default: false},
gang: { type: Boolean, default: false},
});
and example of inserting / creating new:
var conv = new convensations();
conv.members = [userid, user2];
conv.initiateduser = userid;
conv.save(function (err,room) {
edit2:
some debug from query:
getting convensations with userid 59312d2b329b7535b07e273c
Mongoose: convensations.find({ members: ObjectId("59312d2b329b7535b07e273c") }, { fields: {} })
convensations: 0

Change your schema as,
new Schema({
initiateduser : String,
name: {type:String, default: 'no name'},
members: { type: [String], default: []},
time: Number,
global: { type: Boolean, default: false},
gang: { type: Boolean, default: false},
});

Save JSON object to MongoDB inside String field

I'm working with Mongodb(mongoose) and node.js (express.js).
The model of DB is:
var messageSchema = new Schema({
_channel: { type: Schema.ObjectId, ref: 'Channel', required: true },
_user : { type: Schema.ObjectId, ref: 'User', required: true },
datetime: { type: Date, required: true },
messageType: { type: String, required: true },
publish: { type: Boolean, default: false },
content: {
title: String,
text: String,
}
});
I want save JSON object inside text field (string).
The JSON object is this:
{ event: 'push',
repository: { id: 53012902, name: 'RestAPI' },
ref: 'refs/heads/master',
commits:
[ { id: 'a10202e5b5157ae5ccd2d77d7d578046693ae404',
url: 'https://github.com/1izpena/RestAPI/commit/a10202e5b5157ae5ccd2d77d7d578046693ae404',
author: '1izpena' } ],
sender: { login: '1izpena', html_url: 'https://github.com/1izpena' } }
I convert this in String, but the result is:
{"event":"push","repository":{"id":53012902,"name":"RestAPI"},"ref":"refs/heads/master","commits":[{"id":"a10202e5b5157ae5ccd2d77d7d578046693ae404","url":"https://github.com/1izpena/RestAPI/commit/a10202e5b5157ae5ccd2d77d7d578046693ae404","author":"1izpena"}],"sender":{"login":"1izpena","html_url":"https://github.com/1izpena"}}
And this result is not a String, I need to keep the same format to parse it later as json object.
Any idea?
Many thanks
