I want to update the newly created User's data. The returned JSON is:
{
"user":{
"uid":"test123",
"displayName":null,
"photoURL":null,
"email":"test12#test.com",
"emailVerified":false,
"phoneNumber":null,
"isAnonymous":false,
"tenantId":null,
"providerData":[
{
"uid":"test12#test.com",
"displayName":null,
"photoURL":null,
"email":"test12#test.com",
"phoneNumber":null,
"providerId":"password"
}
],
"apiKey":"test123",
"appName":"[DEFAULT]",
"authDomain":"test123.firebaseapp.com",
"stsTokenManager":{
"apiKey":"test123",
"refreshToken":"test123",
"accessToken":"test123",
"expirationTime":1571238989357
},
"redirectEventId":null,
"lastLoginAt":"1571235389108",
"createdAt":"1571235389108"
},
"credential":null,
"additionalUserInfo":{
"providerId":"password",
"isNewUser":true
},
"operationType":"signIn"
}
This is my callout and update:
createUser = async (userData) => {
return await firebase.auth().createUserWithEmailAndPassword(userData.get('userName'), userData.get('password'))
.then((authData) => {
firebase.database().ref('users/' + authData.user.uid + '/').set({
fullName: userData.get('fullName'),
pictures: userData.get('pictures'),
phoneNumber: userData.get('phoneNumber')
});
})
};
Is it possible to add to the User table custom fields?
A few things are happening. It appears that userData can not be seen in the .then statement. So to solve this I attempted to pass in the userData JSON as a param. This did not work. I then broke out each value out of userData, saved it into a const and passed that value. This did not work.
I can see that userData has values in it before the .then statement. I am able to successfully create a new user with the right userName and password. This means to me either:
A - I am not passing the userData JSON correctly or
B - I am not allowed to pass data to firebase like I am doing
My end goal is to sign up a user and then take all of the data they input from a registration form (aka userData) and update the user table with it.
Articles I am using are:
https://firebase.google.com/docs/auth/web/manage-users
https://medium.com/mindorks/firebase-realtime-database-with-react-native-5f357c6ee13b
Main class that calls the createUser function:
const signUp = (dispatch) => {
return async (userData)=>{
try{
const response = await config.createUser(userData);
console.log('sign up resonse1: ' + response); //coming back as undefined
//todo:: figure out how to parse out the apikey out of response
await AsyncStorage.setItem('token', '123mockToken');
dispatch({type: 'sign_up', payload: '123mockToken'});
navigate('mainFlow');
} catch(e){
dispatch({type: 'add_error', payload: '' + e}); //we call dispatch anytime we want to update our state
}
}
};
I understand that the parameter userData holds all the data you want to use for creating the user ("all of the data they input from a registration form").
The following should work:
createUser = async userData => {
try {
const userCredential = await firebase
.auth()
.createUserWithEmailAndPassword(
userData.get('userName'),
userData.get('password')
);
const userId = userCredential.user.uid;
await firebase
.database()
.ref('users/' + userId + '/')
.set({
fullName: userData.get('fullName'),
pictures: userData.get('pictures'),
phoneNumber: userData.get('phoneNumber')
});
return userId; //As per your comment below
} catch (error) {
return error;
}
};
The createUserWithEmailAndPassword() method returns a UserCredential which contains a User.

I am currently writing a multi tenancy app. The app stores data in Firestore/Algolia & I have a cloud function to query the index. This is so that a user can only access data of the tenant they belong to.
The search works fine, but the cloud function keeps on returning null, although the logs shows the search results.
I suspect that the object returned by the Algolia JS client cannot be converted to JSON, hence the httpcallable framework is returning null. Below is a snapshot of the code.
I have tried to stringfy the object using JSON.stringify but no luck. Any ideas?
exports.getCustomerSuggestions = functions.region('europe-central2').https.onCall(async (data, context) => {
if(!context.auth){
throw new functions.https.HttpsError(
'unauthenticated',
'Authentication required.'
);
}
const uid = context.auth.uid;
functions.logger.info("Processing request from user " + uid + " with data: " + JSON.stringify(data));
const client = algoliasearch(algoliaAppId, algoliaApiKey);
const index = client.initIndex(angoliaIndex);
userData = await getUserData(uid);
userData = prepForFirestore(userData.data()); // strip object properties
const searchTerm = data.query;
const filters = 'serviceProviderId:' + userData.tenantId;
var result;
index.search(searchTerm, {
filters: filters
}).then(({hits}) => {
result = hits;
functions.logger.info("Returning: " + JSON.stringify(result)); //The log shows the search results
});
return {status: true, data: result}; // data is returned as null
});
since index.search is asynchronous your function returns before the search finishes. You can try to await the index.search call so that it will wait till the call finishes and after that return
const result = await index.search(searchTerm, {
filters: filters
})
return {status: true, data: result.hits}

Hello.
First time posting on stackoverflow, dont know what kind of information to post, please let me know.
Im trying to make a page (/count) to simply display the number of documents. I've tried different code but nothing is working. This error keeps coming up "TypeError: Converting circular structure to JSON".
This is school work so the code is given to me by a teacher and I have to add a POST method to add a page that displays total number of documents.
Any ideas?
Thanks.
Circular structure is not about mongo but how JS read the JSON object.
For example, if you have this object:
var object = {
propA: "propA",
propB: object
}
When JS try to deserialize JSON object, will handle that: One object contains the object that contain again the object and again and again... that is a circular dependence.
Not only with one object itself, aslo with more objects:
var objectA = {
propA: objectB
}
var objectB = {
propA: objectA
}
Is the same case.
Using node.js you can use util.inspecet() which automatically show [Circular] when a circular dependence is found.
You can use like this:
var util = require('util')
console.log(util.inspect(objectA))
I would like to create user data (name, email, phone number) in Firestore. This should be triggered with on create an authenticated user.
at functions-> src-> index.ts
// Sends email to user after signup
export { welcomeEmail } from './send_email';
// Saves user after signup
export { createUserDoc } from './save_user';
at functions-> src-> save_user.ts
// Firebase Config
import * as functions from "firebase-functions";
import * as firebase from "firebase-admin";
import {MD5} from "crypto-js";
export const createUserDoc = functions.auth.user().onCreate(event => {
const firebaseUser = event.data;
// Use gravatar as default if photoUrl isn't specified in user data
let fileEnding = "jpg";
let photoURL = `https://www.gravatar.com/avatar/${MD5(firebaseUser.email).toString().toLowerCase()}.jpg?s=1024&d=robohash`;
if (firebaseUser.photoURL) {
fileEnding = firebaseUser.photoURL.substr(firebaseUser.photoURL.lastIndexOf(".") + 1);
photoURL = firebaseUser.photoURL;
}
const fileName = `users/${firebaseUser.uid}/profile.${fileEnding}`;
const profilePhotoStorageOpts = {
destination: fileName,
metadata: {
contentType: `image/${fileEnding}`
}
};
const user = {
name: firebaseUser.displayName || "No Name",
email: firebaseUser.email,
photoUrl: `gs://${firebase.storage().bucket().name}/${fileName}`
};
return Promise.all([
firebase.storage().bucket().upload(photoURL, profilePhotoStorageOpts),
firebase.firestore().collection("users").doc(firebaseUser.uid).set(user)
]);
});
The goal was, for each created account I would now find a corresponding user document in Firestore and a profile image in the cloud storage.
instead I'm getting:
Property 'data' does not exist on type 'UserRecord'.ts(2339)
'Promise' only refers to a type, but is being used as a value here. Do you need to change your target library? Try changing the lib compiler option to es2015 or later.ts(2585)
Help would be appreciated. Thanks
As you will see in the documentation for the onCreate method, the first parameter of the handler function is a UserRecord which does not have a data property.
So the first error you get is normal.
In your case, if you want, for example, to get the user's photoURL, you should do event.photoURL (Since event is of type UserRecord). Similarly, you will do event.uid to get the user's uid.
For the second error, you may have a look at https://stackoverflow.com/a/43122423/3371862 or How to resolve 'Build:'Promise' only refers to a type, but is being used as a value here.'
I've got myself a question regarding associations in Sails.js version 0.10-rc5. I've been building an app in which multiple models are associated to one another, and I've arrived at a point where I need to get to nest associations somehow.
There's three parts:
First there's something like a blog post, that's being written by a user. In the blog post I want to show the associated user's information like their username. Now, everything works fine here. Until the next step: I'm trying to show comments which are associated with the post.
The comments are a separate Model, called Comment. Each of which also has an author (user) associated with it. I can easily show a list of the Comments, although when I want to display the User's information associated with the comment, I can't figure out how to populate the Comment with the user's information.
In my controller i'm trying to do something like this:
Post
.findOne(req.param('id'))
.populate('user')
.populate('comments') // I want to populate this comment with .populate('user') or something
.exec(function(err, post) {
// Handle errors & render view etc.
});
In my Post's 'show' action i'm trying to retrieve the information like this (simplified):
<ul>
<%- _.each(post.comments, function(comment) { %>
<li>
<%= comment.user.name %>
<%= comment.description %>
</li>
<% }); %>
</ul>
The comment.user.name will be undefined though. If I try to just access the 'user' property, like comment.user, it'll show it's ID. Which tells me it's not automatically populating the user's information to the comment when I associate the comment with another model.
Anyone any ideals to solve this properly :)?
Thanks in advance!
P.S.
For clarification, this is how i've basically set up the associations in different models:
// User.js
posts: {
collection: 'post'
},
hours: {
collection: 'hour'
},
comments: {
collection: 'comment'
}
// Post.js
user: {
model: 'user'
},
comments: {
collection: 'comment',
via: 'post'
}
// Comment.js
user: {
model: 'user'
},
post: {
model: 'post'
}
Or you can use the built-in Blue Bird Promise feature to make it. (Working on Sails#v0.10.5)
See the codes below:
var _ = require('lodash');
...
Post
.findOne(req.param('id'))
.populate('user')
.populate('comments')
.then(function(post) {
var commentUsers = User.find({
id: _.pluck(post.comments, 'user')
//_.pluck: Retrieves the value of a 'user' property from all elements in the post.comments collection.
})
.then(function(commentUsers) {
return commentUsers;
});
return [post, commentUsers];
})
.spread(function(post, commentUsers) {
commentUsers = _.indexBy(commentUsers, 'id');
//_.indexBy: Creates an object composed of keys generated from the results of running each element of the collection through the given callback. The corresponding value of each key is the last element responsible for generating the key
post.comments = _.map(post.comments, function(comment) {
comment.user = commentUsers[comment.user];
return comment;
});
res.json(post);
})
.catch(function(err) {
return res.serverError(err);
});
Some explanation:
I'm using the Lo-Dash to deal with the arrays. For more details, please refer to the Official Doc
Notice the return values inside the first "then" function, those objects "[post, commentUsers]" inside the array are also "promise" objects. Which means that they didn't contain the value data when they first been executed, until they got the value. So that "spread" function will wait the acture value come and continue doing the rest stuffs.
At the moment, there's no built in way to populate nested associations. Your best bet is to use async to do a mapping:
async.auto({
// First get the post
post: function(cb) {
Post
.findOne(req.param('id'))
.populate('user')
.populate('comments')
.exec(cb);
},
// Then all of the comment users, using an "in" query by
// setting "id" criteria to an array of user IDs
commentUsers: ['post', function(cb, results) {
User.find({id: _.pluck(results.post.comments, 'user')}).exec(cb);
}],
// Map the comment users to their comments
map: ['commentUsers', function(cb, results) {
// Index comment users by ID
var commentUsers = _.indexBy(results.commentUsers, 'id');
// Get a plain object version of post & comments
var post = results.post.toObject();
// Map users onto comments
post.comments = post.comments.map(function(comment) {
comment.user = commentUsers[comment.user];
return comment;
});
return cb(null, post);
}]
},
// After all the async magic is finished, return the mapped result
// (or an error if any occurred during the async block)
function finish(err, results) {
if (err) {return res.serverError(err);}
return res.json(results.map);
}
);
It's not as pretty as nested population (which is in the works, but probably not for v0.10), but on the bright side it's actually fairly efficient.
I created an NPM module for this called nested-pop. You can find it at the link below.
https://www.npmjs.com/package/nested-pop
Use it in the following way.
var nestedPop = require('nested-pop');
User.find()
.populate('dogs')
.then(function(users) {
return nestedPop(users, {
dogs: [
'breed'
]
}).then(function(users) {
return users
}).catch(function(err) {
throw err;
});
}).catch(function(err) {
throw err;
);
Worth saying there's a pull request to add nested population: https://github.com/balderdashy/waterline/pull/1052
Pull request isn't merged at the moment but you can use it installing one directly with
npm i Atlantis-Software/waterline#deepPopulate
With it you can do something like .populate('user.comments ...)'.
sails v0.11 doesn't support _.pluck and _.indexBy use sails.util.pluck and sails.util.indexBy instead.
async.auto({
// First get the post
post: function(cb) {
Post
.findOne(req.param('id'))
.populate('user')
.populate('comments')
.exec(cb);
},
// Then all of the comment users, using an "in" query by
// setting "id" criteria to an array of user IDs
commentUsers: ['post', function(cb, results) {
User.find({id:sails.util.pluck(results.post.comments, 'user')}).exec(cb);
}],
// Map the comment users to their comments
map: ['commentUsers', function(cb, results) {
// Index comment users by ID
var commentUsers = sails.util.indexBy(results.commentUsers, 'id');
// Get a plain object version of post & comments
var post = results.post.toObject();
// Map users onto comments
post.comments = post.comments.map(function(comment) {
comment.user = commentUsers[comment.user];
return comment;
});
return cb(null, post);
}]
},
// After all the async magic is finished, return the mapped result
// (or an error if any occurred during the async block)
function finish(err, results) {
if (err) {return res.serverError(err);}
return res.json(results.map);
}
);
You could use async library which is very clean and simple to understand. For each comment related to a post you can populate many fields as you want with dedicated tasks, execute them in parallel and retrieve the results when all tasks are done. Finally, you only have to return the final result.
Post
.findOne(req.param('id'))
.populate('user')
.populate('comments') // I want to populate this comment with .populate('user') or something
.exec(function (err, post) {
// populate each post in parallel
async.each(post.comments, function (comment, callback) {
// you can populate many elements or only one...
var populateTasks = {
user: function (cb) {
User.findOne({ id: comment.user })
.exec(function (err, result) {
cb(err, result);
});
}
}
async.parallel(populateTasks, function (err, resultSet) {
if (err) { return next(err); }
post.comments = resultSet.user;
// finish
callback();
});
}, function (err) {// final callback
if (err) { return next(err); }
return res.json(post);
});
});
As of sailsjs 1.0 the "deep populate" pull request is still open, but the following async function solution looks elegant enough IMO:
const post = await Post
.findOne({ id: req.param('id') })
.populate('user')
.populate('comments');
if (post && post.comments.length > 0) {
const ids = post.comments.map(comment => comment.id);
post.comments = await Comment
.find({ id: commentId })
.populate('user');
}
Granted this is an old question, but a much simpler solution would be to loop over the comments,replacing each comment's 'user' property (which is an id) with the user's full detail using async await.
async function getPost(postId){
let post = await Post.findOne(postId).populate('user').populate('comments');
for(let comment of post.comments){
comment.user = await User.findOne({id:comment.user});
}
return post;
}
Hope this helps!
In case anyone is looking to do the same but for multiple posts, here's one
way of doing it:
find all user IDs in posts
query all users in 1 go from DB
update posts with those users
Given that same user can write multiple comments, we're making sure we're reusing those objects. Also we're only making 1 additional query (whereas if we'd do it for each post separately, that would be multiple queries).
await Post.find()
.populate('comments')
.then(async (posts) => {
// Collect all comment user IDs
const userIDs = posts.reduce((acc, curr) => {
for (const comment of post.comments) {
acc.add(comment.user);
}
return acc;
}, new Set());
// Get users
const users = await User.find({ id: Array.from(userIDs) });
const usersMap = users.reduce((acc, curr) => {
acc[curr.id] = curr;
return acc;
}, {});
// Assign users to comments
for (const post of posts) {
for (const comment of post.comments) {
if (comment.user) {
const userID = comment.user;
comment.user = usersMap[userID];
}
}
}
return posts;
});
Im using express, body-parser and moongose to build a RESTful web service with Node.js. Im getting json data in the body of a POST request, that function looks like this:
router.route('/match')
// create a match (accessed at POST http://localhost:3000/api/match)
.post(function(req, res) {
if (req._body == true && req.is('application/json') == 'application/json' ) {
var match = new Match(); // create a new instance of the match model
match.name = req.body.name; // set the match name and so on...
match.host = req.body.host;
match.clients = req.body.clients;
match.status = req.body.status;
// save the match and check for errors
match.save(function(err) {
if (err) {
//res.send(err);
res.json({ status: 'ERROR' });
} else {
res.json({ status: 'OK', Match_ID: match._id });
}
});
} else {
res.json({ status: 'ERROR', msg: 'not application/json type'});
}
});
The model Im using for storing a match in the database looks like this:
// app/models/match.js
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var MatchSchema = new Schema({
name: String,
host: String,
clients: { type: [String]},
date: { type: Date, default: Date.now },
status: { type: String, default: 'started' }
});
module.exports = mongoose.model('Match', MatchSchema);
But how do I validate that the json data in the body of the POST request has the key/value fields I want? For clarification, I dont want to insert data in the database that is incomplete. If I test to skip a key/value pair in the json data I get a missing field in the database and when I tries to read req.body.MISSING_FIELD parameter in my code I get undefined. All fields except date in the model is required.
Im using json strings like this to add matches in the database
{"name": "SOCCER", "host": "HOST_ID1", "clients": ["CLIENT_ID1", "CLIENT_ID2"], "status": "started"}
I use a very simple function that takes an array of keys, then loops through it and ensures that req.body[key] is not a falsy value. It is trivial to modify it to accommodate only undefined values however.
In app.js
app.use( (req, res, next ) => {
req.require = ( keys = [] ) => {
keys.forEach( key => {
// NOTE: This will throw an error for ALL falsy values.
// if this is not the desired outcome, use
// if( typeof req.body[key] === "undefined" )
if( !req.body[key] )
throw new Error( "Missing required fields" );
})
}
})
in your route handler
try{
// Immediately throws an error if the provided keys are not in req.body
req.require( [ "requiredKey1", "requiredKey2" ] );
// Other code, typically async/await for simplicity
} catch( e ){
//Handle errors, or
next( e ); // Use the error-handling middleware defined in app.js
}
This only checks to ensure that the body contains the specified keys. IT won't validate the data sent in any meaningful way. This is fine for my use case because if the data is totally borked then I'll just handle the error in the catch block and throw an HTTP error code back at the client. (consider sending a meaningful payload as well)
If you want to validate the data in a more sophisticated way, (like, say, ensuring that an email is the correct format, etc) you might want to look into a validation middle-ware, like https://express-validator.github.io/docs/
