I'm trying to set a default value to a field when I create a new item in the database, but I can't make it to work.
I am using SailsJS 0.12.1 currently, which is the latest version
This is how my file looks like:
models/Users.js
module.exports = {
schema: true,
attributes: {
firstName: {
type: 'string',
required: true,
},
role: {
type: 'string',
enum: ['admin', 'user', 'limited', 'suspended', 'deleted'],
defaultsTo: 'limited'
},
}
}
When the element is created in the database, I don't get the role value. It looks like that:
{
"_id": {
"$oid": "56f8616163a59cf813998f8a"
},
"firstName": "Alex",
"createdAt": {
"$date": "2016-03-27T22:40:33.151Z"
},
"updatedAt": {
"$date": "2016-03-27T22:40:33.151Z"
}
}
Any idea what I forgot?
Thanks!
I had a similar issue earlier today. I was able to resolve this by adding required is 'true'.
Example of New User Model:
module.exports = {
schema: true,
attributes: {
firstName: {
type: 'string',
required: true,
},
role: {
type: 'string',
required: true,
enum: ['admin', 'user', 'limited', 'suspended', 'deleted'],
defaultsTo: 'limited'
},
}
}
I hope this helps.

I am using the mongoose updateMany() method and I also want to keep it a part of transaction. The documentation shows the example of save() where I can do something like Model.save({session: mySession}) but don't really know how to use it with for example Model.updateMany()
UPDATE:
For example I have two models called SubDomain and Service and they look like this respectively:
SUB-DOMAIN
{
name: {
type: String,
required: true,
},
url: {
type: String,
required: true,
unique: true,
},
services: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "Service",
},
],
user: {
type: mongoose.Schema.Types.ObjectId,
ref: "User",
},
}
SERVICE:
{
name: {
type: String,
required: true,
},
description: {
type: String,
required: true,
},
price: { type: Number },
tags: { type: Array },
packages: [
{
name: { type: String, required: true },
description: { type: String, required: true },
price: { type: Number, required: true },
},
],
map: { type: String },
isHidden: {
type: Boolean,
required: true,
default: false,
},
sortingOrder: { type: Number },
isForDomain: { type: Boolean, required: false, default: false },
isForSubDomain: { type: Boolean, required: false, default: false },
subDomains: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "SubDomain",
},
],
}
Now the main field here is the services field in SubDomain and subDomains field in Service.
The complicated part😅:
Whenever the user wants to create new service, I want to $push that service's _id into the array of services of all the subDomains inside that new service
And for that, I am using the updateMany() like this:
const sess = await mongoose.startSession();
sess.startTransaction();
const newService = new Service({
_id: mongoose.Types.ObjectId(),
subDomains: req.body.subDomains
...foo
})
await SubDomain.updateMany(
{ _id: { $in: req.body.subDomains } },
{ $push: { services: newService._id } }
);
The problem starts here, of course I can do:
newService.save({session: sess})
but how do I keep my SubDomain's updateMany in the same transaction (i.e sess)
I know my example is difficult to wrap your head around but I have tried to pick a simplest example rather than copying the exact same code which would have been a lot more difficult
I am using Mongoose 5.1.7 and attempting to create a compound index across multiple text indexes in my defined schema. Here is my schema definition:
const mongoose = require('mongoose');
const alumniSchema = mongoose.Schema({
firstName: {
type: [String],
required: true
},
lastName: {
type: [String],
required: true
},
classYear: {
type: Number,
required: true
},
photoURL: {
type: String,
},
education: [
{
school: {
type: String,
required: true
},
gradYear: {
type: Number,
required: true
},
degreeType: String,
degreeSubject: String,
}
],
jobs: [
{
employer: {
type: String,
required: true
},
position: String,
startDate: Date,
endDate: Date,
isCurrent: Boolean
}
],
contactInfo: {
phoneNumber: {
type: String,
},
email: {
type: String,
}
},
})
alumniSchema.index({ firstName: 'text', lastName : 'text', email: 'text' });
module.exports = mongoose.model('Alumni', alumniSchema);
When I boot up the server, I receive the following error:
MongoError: Index: { v: 2, key: { _fts: "text", _ftsx: 1 }, name: "firstName_text_lastName_text_email_text", ns: "5b3be578c0c6e317f7c1bc2b_test.alumnis", background: true, weights: { email: 1, firstName: 1, lastName: 1 }, default_language: "english", language_override: "language", textIndexVersion: 3 } already exists with different options: { v: 2, key: { _fts: "text", _ftsx: 1 }, name: "firstName_text_lastName_text_classYear_text_education.school_text", background: true, weights: { classYear: 1, education.school: 1, firstName: 1, lastName: 1 }, default_language: "english", language_override: "language", ns: "5b3be578c0c6e317f7c1bc2b_test.alumnis", textIndexVersion: 3 }
I have been messing around with this for a while and evidently previously created an index. When I use the mongo shell to check the indexes that I currently have set up, however, I cannot find the index "firstName_text_lastName_text_classYear_text_education.school_text" referenced by the error message:
> db
test
> db.collection.getIndexes()
[ ]
I am at an impasse--I'm not sure if I've incorrectly created the index, or if I am supposed to drop the index (it doesn't look like Mongoose natively supports a dropIndex() function).
Has anyone else dealt with this issue? Thanks!
Looks like Mongoose dynamically creates the index at runtime. The trick for me was adding:
var Alumni = mongoose.model('Alumni', alumniSchema);
Alumni.collection.dropIndex('firstName_text_lastName_text_classYear_text_education.school_text', function(err, result) {
if (err) {
console.log('Error dropping index!', err);
}
});
and then restarting the server.
THEN I was able to change the index to whatever I wanted. Note that I still needed to add the above code segment and restart the server every time I wanted to update the index.
I am using the Express-Restify-Mongoose library to generate all of my endpoints for a REST api.
I am storing my schemas in a collection named 'core_schema.' Each time the server starts all records within that collection are grabbed using a find() method. This provides an array of all available collections with defined schemas.
db.on('open', function(){
findDocs('core_schema', {}, function(docs){
var tempString = JSON.stringify(docs);
var tempObj = JSON.parse(tempString);
for (var i = 0; i < tempObj.length; i++) {
var temp_schema = new mongoose.Schema(tempObj[i].schema_data, { collection: tempObj[i].collection_name });
var temp_model = mongoose.model(tempObj[i].collection_name, temp_schema);
restify.serve(router, temp_model, { plural: false, name: tempObj[i].collection_name, preCreate: setDateTimes });
}
});
});
I would like to be able to make changes to the schema to enforce new POST rules, but when I try to use a test example like:
mongoose.model('core_user').schema = new mongoose.Schema({
update_count: { type: "String", required: false },
created_date: { type: "String", required: false },
created_by: { type: "String", required: false },
updated_date: { type: "String", required: false },
updated_by: { type: "String", required: false },
first_name: { type: "String", required: true },
last_name: { type: "String", required: true },
username: { type: "String", required: true },
password: { type: "String", required: true },
somethingElse: { type: "String", required: true }
}, {collection: 'core_user'})
Where 'somethingElse' is the new field I am trying to enforce it does not enforce it. What am I doing wrong? Is there no way to update the model to use the new schema?
To update a Mongoose schema, you'll need to use the Schema.add method. You can update the schema for a model using the code below:
mongoose.model('core_user').schema.add({ somethingElse: {
type: 'String',
required: true
}});
I have an upsert query in mongoose which was working in 3.8 but, after I've upgraded to 4 I'm getting
Unable to invalidate a subdocument that has not been added to an array
this is my model:
var ActivitySchema = new Schema({
owner:{
type: Schema.Types.ObjectId,
ref: 'User'
},
sequence:{
type:Number,
default: 0
},
items:[
{
posted:{
type:Date,
default:Date.now
},
verb:{
type: String,
enum: [ 'leave','join','support','share','comment', 'upload', 'rate','message','update', 'signup']
},
text:{
type: String,
},
reference: {
objectType:{
type: String,
enum: [ 'document','element','process', 'project', 'user']
},
refObj:{}
}
}]
});
the upsert:
Activity.update({
$and:[
{'owner':ownerId},
{'sequence':bucket}
]},
{
$push:{items:newItem }
},
{
upsert:true
}).execAsync();
and the data is like this:
//newItem
{ verb: 'join',
text: 'Has joined to a team',
reference:
{
refObj: { teamId: '56269fd1e923cc7a7b46dcf8', name: 'test1' },
objectType: 'user'
}
}
ownerId is a mongoId like 56251c01507dc35423694118
and bucket is an integer 0
is there any breacking change that I need to be aware?, I've been looking and I haven't found yet related, any other workaround, solution?
I had encountered the same problem, if it is the same case then make sure all fields type are matched to the mongoose.model('yourModel').
Hopes that helps.
