what's the delete used for? I didn't see such grammar before, can anybody help me?
the code snippet is very easy and it is used the node.js , mongoose , mongodb
function _update(game, callback) {
if (!game) {
callback(new Error("Game must be provided."));
return;
}
if (!game.gameId) {
callback(new Error("Game id should be provided"));
return;
}
var updates = (game instanceof Game) ? game.toObject() : game;
delete updates._id;
updates.modifiedDate = new Date();
Game.findOneAndUpdate({"_id": game.id, "deleted" : {"$ne": true}}, updates, callback);
}
delete in JavaScript removes the property from the object.
var game = {
id: 1
}
console.log(game); // Object {id: 1}
delete game.id
console.log(game); // undefined
It is used to remove a property from an object. So in this instance it removes the _id property from updates

I have a partner record where I would like to change the form if the category field is set to a certain value. However, I can't use this with certain SuiteScript functions because changing the form wipes out any changes that were made to the record. I'm trying to work around this using an afterSubmit function that will use record.SubmitFields to change the form and then redirect.toRecord to reload the page with the change. However, it's not changing the form value. Is there a way to do this with record.submitFields? Am I doing something incorrectly?
var currentRecord = scriptContext.newRecord;
var category = currentRecord.getValue('category');
if(category == '3'){
try{
record.submitFields({
type: record.Type.PARTNER,
id: currentRecord.id,
values: {
'customform': '105'
}
});
log.debug('success');
} catch (e) {
log.error({title: 'error', details: e});
}
}
redirect.toRecord({
type: 'partner',
id: currentRecord.id,
});
}
Yes you can. Whenever you create a url for a record you can generally add a cf parameter that takes the form id. It's the same vaule you'd use if you were setting the field 'customform'. So just skip the submitFields part and do:
redirect.toRecord({
type: 'partner',
id: currentRecord.id,
parameters:{
cf:105
}
});
You can also set the custom form using the submitFields call but that only works for some types of records.
If you need to do this in the beforeLoad here is a fragment in Typescript. The trick to avoid an infinite loop is to check to see if you already have the correct form:
export function beforeLoad(ctx){
let rec : record.Record = ctx.newRecord;
let user = runtime.getCurrentUser();
if(user.roleCenter =='EMPLOYEE'){
if(rec.getValue({fieldId:'assigned'}) != user.id){
throw new Error('You do not have access to this record');
return;
}
}else{
log.debug({
title:'Access for '+ user.entityid,
details:user.roleCenter
});
}
if(ctx.type == ctx.UserEventType.EDIT){
var approvalForm = runtime.getCurrentScript().getParameter({name:'custscript_kotn_approval_form'});
let rec : record.Record = ctx.newRecord;
if( 3 == rec.getValue({fieldId:'custevent_kotn_approval_status'})){
if(approvalForm != rec.getValue({fieldId:'customform'}) && approvalForm != ctx.request.parameters.cf){
redirect.toRecord({
type: <string>rec.type,
id : ''+rec.id,
isEditMode:true,
parameters :{
cf:approvalForm
}
});
return;
}
}
}
Suppose a schema
const sch = new mongoose.Schema({
obj: {
subObj: String;
}
});
Then I observe that an non-existing or empty property of a document gives me isEmpty == false.
import { isEmpty } from 'lodash';
// Insert an empty document (i.e. no `obj` property)
Sch.create([{}]);
Sch.findOne({}. (err, doc) => {
// Below gives `{}`
console.log(doc.obj);
// Below gives `false`
console.log(`isEmpty == ${isEmpty(doc.obj)`);
});
I suspect that it is because the document contains obj as its key, i.e. Object.keys(doc).includes('obj') == true or Object.getOwnPropertyNames(doc).includes('obj') == true. But I have no idea to deal with it.
What is a proper way to check emptiness of a mongoose document property ?
Update:
The reason that you are getting that is:
console.log(Object.keys(doc.obj), Object.keys({}));
when running the command above I get: [ '$init', 'subObj' ] [] which means that your Object is not really empty, lodash is probably checking those attributes
You could use something like this:
Sch.findOne({}, (err, doc) => {
if (JSON.stringify(doc.obj) === JSON.stringify({}) ) {
// logic goes here
}
});
I found the solution in mongoose itself. The below does what I tried with lodash
doc.$isEmpty('obj')
Reference
Document.prototype.$isEmpty()
I want to do is update a record and insert it if it doesn't exist with mongoose. Here is my code:
module.exports.upsertUser = function(user) {
var options = {userName : 'Ricardo'}
Users.findOneAndUpdate({email: user.email}, options, {upsert:true}).exec();
}
And:
var promise = Users.upsertUser(user);
promise
.then(function(results){
...
}
.catch(function(err){
...
}
When I execute the promise, each time a new user is created with the same email.
I'm not sure if I'm performing the update incorrectly. I've tried it in the same way but with update and it does not work either.
Can you help me? Thanks!
You need to put the return without the exec:
module.exports.upsertUser = function(user) {
var options = {userName : 'Ricardo'}
return Users.findOneAndUpdate({email: user.email}, options, {upsert:true, new: true});
}
var promise = Users.upsertUser(user);
promise.then(function(results){
if(results) {
console.log(results);
} else {
console.log('!results');
}
}.catch(function(err){
...
}
FYI:
The default is to return the unaltered document. If you want the new, updated document to be returned you have to pass an additional argument: {new:true} with the upsert option.
according to your coding what findOneAndUpdate() does is that it finds this document/user's document that you are looking for to edit which in this case what you are using to search for this user's document that you want to edit it's document is with his email. Now your second argument modifies that part of the document that you wanted to modify, but this option has to be attached with some mongodb operators (pay a visit to this link for a list of them: https://docs.mongodb.com/manual/reference/operator/update/) but in your case what you need is the $set operator.so i would modify your code like this:
module.exports.upsertUser = function(user) {
var options =
Users.findOneAndUpdate({email: user.email}, {$set:{
userName : 'Ricardo'
}}, {
returnOriginal: true}).exec();
};
so try the above modification let's see how it works
I'm building a step counter app.
I got an iOS app that pushes the sum of each day to /users/{mobile}/steps/{date}/
When a new steps child is updated or added, I want to sum the value of all the steps for that particular user and update his stepsTotal.
To achieve that I need to
Find the original user and sum all the steps.
Save the new value to stepsTotal.
I would be most grateful if someone could give some help here. :-)
database
{
"users": {
"92291000": {
"firstName": "Tore",
"stepsTotal": "1500",
"steps": {
"02-09-2017": "500",
"03-09-2017": "1000"
},
import.js
var db = admin.database();
var dbRoot = db.ref("/");
var usersRef = dbRoot.child("users");
// This works
function saveUser(attributes) {
let mobile = attributes.mobile;
delete attributes['mobile']
let user = usersRef.child(mobile);
user.update(attributes);
}
function increaseSteps( { mobile=null, steps=null } = {}) {
// Find the User
console.log("looking for mobile", mobile); // OK
let userRef = usersRef.child(mobile);
// Here I'm not able to read the old data from the user.
userRef.transaction(function(user) {
console.log("user: ", user); // null
// ^ User is null.
});
/*
If I mangage to find user above, I expect to do something like this.
Or it is possible to only update *stepsTotal*?
*/
let attributes = {
firstName: user.firstName,
lastName: user.lastName,
stepsTotal: user.stepsTotal + steps,
}
user.update( attributes );
}
If I understand correctly, you have a problem in this snippet of the code:
let userRef = usersRef.child(mobile);
// Here I'm not able to read the old data from the user.
userRef.transaction(function(user) {
console.log("user: ", user); // null
// ^ User is null.
});
In Firebase Database transactions the initial value is often null. From the Firebase documentation on transactions:
Transaction Function is Called Multiple Times
Your transaction handler is called multiple times and must be able to handle null data. Even if there is existing data in your database it may not be locally cached when the transaction function is run.
This is due to how Firebase transactions work behind the scenes. To learn more about that, see my answers here Transcation updateFunction parameter is null and Firebase runTransaction not working.
The solution is to handle both cases: if the user node doesn't exist yet count the initial number of steps, otherwise update the number of steps:
let userRef = usersRef.child(mobile);
userRef.transaction(function(user) {
return (user || 0) + new_steps_for_user;
});
I'm trying to get the object id after adding it to the db (using collection.insert)
mongoose.model('Persons').collection.insert(person, function(err, newPerson) {
console.log('lets see you', newPerson);
});
and from the console I'm getting only result: { ok: 1, n: 1 } in stand of the new obj, any ideas how can I rich to the new object ?
thanks!
You can use save() here
var Persons = mongoose.model('Persons');
var personJSON = {
..... // persons schema values you want to insert
};
var person = new Persons(personJSON);
var result = yield person.save();
result variable will contain all the fields you inserted along with _id
