I've been reading countless tutorials and I'm not able to get any data to appear in the firebase database at all. I'm trying to get this structure
"my-app-name": {
"users": {
"uid-of-user": {
"email": "them#them.com",
"todoitems": {
}
}
}
}
First of all I'm not sure how to acquire that structure. Under "my-app-name" in the visual editor, I've put "users" = "". I'm not sure if that's the way to star establishing users as an empty object. Or maybe I shouldn't be dealing with the visual editor at all? Here's my createNewUser controller that should be persisting new users to the database:
function LoginController($scope, Auth, $state, $location, $firebaseObject, $firebase) {
$scope.createNewUser = createNewUser;
$scope.signupComplete = "";
function createNewUser() {
var ref = new Firebase("https://sizzling-torch-655.firebaseio.com/");
//CREATE USER
Auth.$createUser({
email: $scope.email,
password: $scope.password
}).then(function(userData) {
//THIS SHOULD BE PERSISTING IT TO THE DATABASE
var user = $firebaseObject(ref.child('users').child(userData.uid));
user.$loaded().then(function() {
var newUser = {
emailAddress: $scope.email,
};
user.$ref.$set(newUser);
})
// $location.path("/home");
}).catch(function(error) {
$scope.responseMessage = error;
});
};
};
It should be noted I haven't created the users object yet in the firebase database. Any help is extremely appreciated. Thank you very much.
Clarification
Auth.$creatUser is:
app.factory("Auth", ["$firebaseAuth", function($firebaseAuth) {
return $firebaseAuth(ref);
}]);
I've successfully created users and see them appear in the Login/Users tab of the Firebase dashboard. I'm not able to store them into the database though.
And userData.uid is the userData object that was returned from the then part of the $createUser function.
EDIT 2
These are my security and rules. Could this be affecting me writing user data to the database?
This is going to be a todo app. Users should be able to only have access to their own data.
{
"rules": {
// public read access
".read": true,
"users": {
"$uid": {
".write": "$uid === auth.uid"
}
}
}
}
Firebase Authentication does not automatically store user information in the database. If you want to store such information in the database, you will have to write the necessary code for that yourself.
From your snippet:
//THIS SHOULD BE PERSISTING IT TO THE DATABASE
var user = $firebaseObject(ref.child('users').child(userData.uid));
This code does not store any information in the database either. Instead it tries to read the user's data from the database. But since you didn't write it there in the first place, the read will accomplish nothing and the then() will never execute.
The solution is to write the necessary user data into the database, when the user authenticates.
var user = $firebaseObject(ref.child('users').child(userData.uid));
var newUser = {
emailAddress: $scope.email,
};
user.$ref.$set(newUser);

With Realm sync of MongoDB, I'm trying to launch a trigger when a realm user is created to insert his newly created ID into my cluster. Here's the javascript function I made that is being called by the trigger :
exports = async function createNewUserDocument({ user }) {
const users = context.services
.get("mongodb-atlas")
.db("BD")
.collection("patients");
const query = { email: context.user.data.email };
const update = {
$set: {
patientId: context.user.id
}
};
// Return the updated document instead of the original document
const options = { returnNewDocument: true };
console.log(context.user.data.email);
return users.findOneAndUpdate(query, update, options)
.then(updatedDocument => {
if(updatedDocument) {
console.log(`Successfully updated document: ${updatedDocument}.`)
} else {
console.log("No document matches the provided query.")
}
return updatedDocument
})
.catch(err => console.error(`Failed to find and update document: ${err}`))
};
When running from the embed editor, while specifying the proper user manually, it's working perfectly. However, when launched by the trigger, it looks like the user is the system user and not the created user, because the error I get in the logs is the same I get when I run from the editor by specifying System user, which is Failed to find and update document: FunctionError: cannot compare to undefined. This makes sense because the System user is not a user per se, so the context.user is undefined.
I find it weird since I specify in the function settings that it should be executed with the permissions of the user calling the function. So my question is, is it possible to access the user.context of a user on his creation, and if so, how would I do it ?
Good day,
I've been trying to learn a bit of angular and nodejs. I found a tutorial on a realtime chat app and made some few adjustment to some function of the code. But the one aspect that I cannot seem to get right is the ability for the user to post to a feed. The login process works, the user is already logged in but the user can't post. I would also like to be able to get all they data i insert from all the user to show up like a normal feedview will. Please assist.
Here are my files:
FROM MY CONTROLLER HERE IS THE CODE WHEN THE BUTTON IS PRESSED
$scope.postDatatoDd = () => {
appService.httpCall({
url: '/posts',
params: {
'posts': $scope.data.info,
'from_user_id': $scope.data.username
}
})
.then((response) => {
// $scope.$apply();
})
.catch((error) => {
alert(error.message);
});
}
and here is my route file:
this.app.post('/posts', async(request,response) => {
const reqResponse = {}
const data = {
posts : request.body.postDatatoDd,
from_user_id: request.body.username
};
if (data.posts === ''){
reqResponse.error = true;
reqResponse.message = `error, input`;
response.status(412).json(reqResponse);
} else {
const result = await helper.insertFeed(data);
if (result === null) {
reqResponse.error = true;
reqResponse.message = `they was an error.`;
response.status(417).json(reqResponse);
} else {
reqResponse.error = false;
reqResponse.userId = result.insertId;
reqResponse.message = `posted succesfully`;
response.status(200).json(reqResponse);
}
}});
and in my helper file there is this function to insert data:
async insertFeed(params){
try {
return await this.db.query(
`INSERT INTO posts (from_user_id,posts) values (?,?)`,
[params.from_user_id,params.postDatatoDd]
);
} catch (error) {
console.warn(error);
return null;
}
}
On the client side here is the button with :
<label for="postDatatoDd">Post</label>
<input type="text" id="postDatatoDd"
ng-model="data.postDatatoDd"
class="feed form-control"
placeholder="post your data here?"
/>
<button ng-click="postDatatoDd()" class="btn btn-primary">Post</button>
</div>
--- EDIT 1---
Data is being inserted now, but it is receiving the values as (NULL, NULL).
--- EDIT 2 ---
After closely looking at the code and fixing some naming variables the code works fine, the data is being inserted in mysql as it should.
Other than a lot of typos when it comes to the variables reference. The code seem to be fine.
Assuming that you using appservice class somewhere in your code and its functioned, then everything else will work.
You are getting the (NULL, NULL) because you are parsing parameters that are not being properly parsed out to your helper file, please close attention to that.
appService
.httpCall({
url: "/posts",
params: {
posts: $scope.data.postbuzz,
from_user_id: $scope.data.username,
},
})
.then((response) => {
$scope.$apply();
})
.catch((error) => {
alert(error.message);
});
make sure that the data that you calling from this above function is similar to $scope parameter you passing in your route file that your requesting:
const data = {
posts : request.body.posts,
from_user_id: request.body.from_user_id}
and in your database helper class you running:
`INSERT INTO posts (from_user_id,post) values (?,?)`,
[params.from_user_id,params.posts]
Hope this was helpful
You seem to have an understand already. your question may help a lot more people in the future.
params should be as following, since the data object has properties from_user_id and posts
`INSERT INTO posts (from_user_id,posts) values (?, ?)`,
[params.from_user_id,params.posts]

If you are new to Angular you can use the code as reference.
I have a sample code that goes like this:
Client Helper:
getUsername: function (userId) {
Meteor.call("getUsername", userId, function (err, result) {
if(!err) {
Session.set("setUsername", result);
else {
console.log(err);
}
});
return Session.get("setUsername");
}
Server
Meteor.methods({
"getUsername": function (userId) {
var x = Meteor.users.find({_id: userId}, {fields: {username:1}}).fetch()[0];
return x.username;
}
});
The result of this code is an infinite loop of username passing to the client. Is there a way to stop the loop and pass only the data that is needed on the client? I believe the reactivity is causing the data to loop infinitely and I am not sure how to stop it. I tried using "reactive":false on my query in the server but it does not work.
If you want to access username everywhere in client templates (so thats why you put it into session), I would not set it in template helper. I would set it on startup and get username from session in template helpers (without calling server method)
If you need username just in one template, so you want to return its value from your template helper, do not put it into session, just return it in your server method callback.
Based on your sample code, I assume, you have a set of posts and you are retrieving user name based on user id for each post. Then instead of doing it this way, you should use publish composite package to publish related users as well.
Meteor.publishComposite('getPosts', function (postIds) {
return [{
find: function() {
return Posts.find({ _id: { $in: postIds }});
// you can also do -> return Posts.find();
// or -> return Posts.find({ /* or what ever your selector is to get the posts you need*/ });
},
children: [{
find: function(post) {
return Meteor.users.find({
id: post.userId //or the correct field in your post document to get user id
}, {
fields: {
"profile": 1
}
});
}
}}
}]
});
This way your publication will take care of publishing related users along with posts. You don't need to use methods and call them each time.
so I'm using Parse to handle a Stripe enabled app. We want our users to be able to cash out their in app credits, and we're planning on using Stripe to handle that. I've been able to create Customers in Stripe successfully, and link a bank account to these. Now I'm trying to initiate a transfer to one of these bank accounts, following
https://stripe.com/docs/tutorials/sending-transfers
But I'm running into an issue where Stripe.recipients is undefined.
Relevant code:
Initialization of Stripe:
var Stripe = require('stripe');
Stripe.initialize('sk_test_ukk7e8B46I39nxoUd6XILpPZ');
Parse Cloud Function for transferring:
Parse.Cloud.define("startTransfer", function(request, response) {
var userObjectId = request.params.userObjectId;
var credits = request.params.credits;
var StripeCustomer = Parse.Object.extend("StripeCustomer");
var stripeCustomerQuery = new Parse.Query(StripeCustomer);
stripeCustomerQuery.equalTo("userObj", userObjectId);
stripeCustomerQuery.find({
success: function(results) {
if(results.length == 0) {
} else if(results.length == 1) {
var customer = results[0];
// handle returning customer adding a new card
Stripe.Recipients.create({
name: customer.description,
type: "individual",
bank_account: customer.source,
email: customer.email
}, function(err, recipient) {
// recipient;
console.log("have a recipient");
if(err == nil) {
Stripe.transfers.create({
amount: credits,
currency: "usd",
recipient: recipient,
bank_account: customer.source,
statement_descriptor: "Cash Out"
}, function(err1, transfer) {
// asynchronously called
if(err == nil) {
response.success("Successfully transferred funds");
} else {
response.error(err1);
}
});
} else {
response.error(err);
}
});
}
}, error: function(error) {
reponse.error(error);
}
});
});
I'm calling this from iOS, using the PFCloud.callFunction API call. It seems to be hitting this code properly, but Recipients is said to be undefined in the error message, but the Stripe documentation requires it. How can I solve this?
Turns out, the Stripe cloud code module is indeed using an older version of Stripe. Therefore, according to this bug report, the solution is to download the newer SDK and manually add it to cloud code modules.
Source:
https://developers.facebook.com/bugs/523104684492016/
Actual post from the bug report (from Facebook employee):
Parse modules are using an old version of the API and there is no plan to update it in the near future.
As a workaround please download the newer SDKs directly off the third party site, place it in "cloud/" folder and import it using require();
We're going to close this by design.
Working on my social app I've found a strange behavior in the collection Meteor.users, this problem does not occur with other Collections using the same methodologies
I would like to have an initial list of users downloading a minimum number of information for everyone and when I open the panel to a specific user I subscribe a different showing more information if the specified user is a friend of mine.
But after subscribe the client collection Meteor.users is not updated!
CLIENT
Meteor.startup(function() {
Meteor.subscribe('usersByIds', Meteor.user().profile.friends, function() {
//... make users list panel using minimal fields
});
//performed when click on a user
function userLoadInfo(userId) {
Meteor.subscribe('userById', userId, function() {
var userProfile = Meteor.users.findOne(userId).profile;
//...
//make template user panel using full or minimal user fields
//...
//BUT NOT WORK!
//HERE Meteor.users.findOne(userId) keep minial user fields!!
//then if userId is my friend!
});
}
});
SERVER
//return minimal user fields
getUsersByIds = function(usersIds) {
return Meteor.users.find({_id: {$in: usersIds} },
{
fields: {
'profile.username':1,
'profile.avatar_url':1
}
});
};
//return all user fields
getFriendById = function(userId) {
return Meteor.users.find({_id: userId},
{
fields: {
'profile.username':1,
'profile.avatar_url':1
//ADDITIONAL FIELDS
'profile.online':1,
'profile.favorites':1,
'profile.friends':1
}
});
};
//Publish all users, with minimal fields
Meteor.publish('usersByIds', function(userId) {
if(!this.userId) return null;
return getUsersByIds( [userId] );
});
//Publish user, IF IS FRIEND full fields
Meteor.publish('userById', function(userId) {
if(!this.userId) return null;
var userCur = getFriendById(userId),
userProfile = userCur.fetch()[0].profile;
if(userProfile.friends.indexOf(this.userId) != -1) //I'm in his friends list
{
console.log('userdById IS FRIEND');
return userCur; //all fields
}
else
return getUsersByIds( [userId] ); //minimal fields
});
This is a limitation or bug in DDP. See this.
A workaround is to move data out of users.profile.
Like this:
//limited publish
Meteor.publish( 'basicData', function( reqId ){
if ( this.userId ) {
return Meteor.users.find({_id: reqId },{
fields: { 'profile.username':1,'profile.avatar_url':1}
});
}
else {
this.ready();
}
});
//friend Publish
Meteor.publish( 'friendData', function( reqId ){
if ( this.userId ) {
return Meteor.users.find( {_id: reqId, 'friendProfile.friends': this.userId }, {
fields: {
'friendProfile.online':1,
'friendProfile.favorites':1,
'friendProfile.friends':1
}
});
}
else {
this.ready();
}
});
//example user
var someUser = {
_id: "abcd",
profile: {
username: "abcd",
avatar_url: "http://pic.jpg"
},
friendProfile: {
friends: ['bcde', 'cdef' ],
online: true,
favorites: ['stuff', 'otherStuff' ]
}
}
As given in a comment, this link reveals your problem. The current DDP Protocol does not allow publishing of subdocuments. One way to get around this is to create a separate collection with your data but a better way would probably to just remove some of the data and make it a direct object off of your user.
The best way to do this is add the data to your user's profile upon insert and then in the onCreateUser move the data onto the user directly:
Accounts.onCreateUser(function(options, user) {
if (options.profile) {
if (options.profile.publicData) {
user.publicData = options.profile.publicData;
delete options.profile.publicData;
}
user.profile = options.profile;
}
return user;
});
If you are allowing clients to perform user inserts make sure you validate the data better though. This way you can have the online, favorites, and friends in the profile and publish that specifically when you want it. You can then have username and avatar_url in the publicData object directly on the user and just always publish all-the-time.
