Firebase checkin system schema

I am trying to create a checking system using firebase, the way it would work is that it would take the business user uid and the then person checking in uid.
The database looks something like this :
Would this work or is there no way to concurrently get two uids?
EDIT
In my haste I forgot to add the code that I tried:
firebase.auth().onAuthStateChanged(function(user) {
if(user) {
var buisnesscheckedin = db.ref("checkedin/" + user.uid)
checkinButton.addEventListener('click', function(e) {
e.preventDefault()
buisnesscheckedin.push({
status: 'true'
})
console.log("Checked In")
})
}
else {
window.location.href = 'index.html'
}
})
This is what I tried but the problem is that I want to be able to get the uid associated with the business instead of using the consumers uid first.
So the path should look this:
checkedin/buisness_uid/consumer_uid/

Parse-server social login

I am developing application based on Parse-server and I want to offer social login. I found this guide in the documentation http://docs.parseplatform.org/js/guide/#linking-users.
I started to implement the social login by google. I did following steps:
1) I added following lines to the ParseServer settings
var api = new ParseServer({
...
auth:{
google: {}
},
...
});
2) I did the authentication by hello.js on the client side (call user._linkWith function on login)
hello.init({
google: 'My Google id'
});
hello.on('auth.login', function(auth) {
// Call user information, for the given network
hello(auth.network).api('me').then(function(r) {
const user = new Parse.User();
user._linkWith(auth.network, auth.authResponse).then(function(user){
console.log('You are logged in successfully.');
});
});
});
When I debugged it, I found that it fails in _linkWith() function, when provider object is preparing. Object AuthProviders, which should store all providers, is empty. Because of it the statement provider = authProviders['google']; leads to undefined. Invoking provider.authenticate(...); leads to error "Cannot read property 'authenticate' of undefined"
What am I missing or what am I doing wrong?
Thanks for all your answers.

Did you register the authenticationProvider? You can find examples in our unit tests on how to do so:
https://github.com/parse-community/parse-server/blob/5813fd0bf8350a97d529e5e608e7620b2b65fd0c/spec/AuthenticationAdapters.spec.js#L139

I also got this error and looked at the _linkWith(provider, options) source code. It checks if options has an authData field (which in turn should contain id and credentials). If so, it uses options.authData. Otherwise it falls back on looking up a previously registered authentication provider mentioned in the previous answer.
This is a fragment of the code I'm using:
const authData = {
"id": profile.getId(),
"id_token": id_token
}
const options = {
"authData": authData
}
const user = new Parse.User();
user._linkWith('google', options).then(function(user) {
console.log('Successful user._linkWith(). returned user=' + JSON.stringify(user))
}, function(error) {
console.log('Error linking/creating user: ' + error)
alert('Error linking/creating user: ' + error)
// TODO handle error
})

How to prevent current user get notified?

I'm making an app that allows user to like and comment on other user post. I'm using Parse as my backend. I'm able to notified user everytime their post liked or commented. However if current user like or comment on their own post this current user still notified. How can I prevent this?
Here is the js code that I use:
Parse.Cloud.afterSave('Likes', function(request) {
// read pointer async
request.object.get("likedPost").fetch().then(function(like){
// 'post' is the commentedPost object here
var liker = like.get('createdBy');
// proceed with the rest of your code - unchanged
var query = new Parse.Query(Parse.Installation);
query.equalTo('jooveUser', liker);
Parse.Push.send({
where: query, // Set our Installation query.
data: {
alert: message = request.user.get('username') + ' liked your post',
badge: "Increment",
sound: "facebook_pop.mp3",
t : "l",
lid : request.object.id,
pid: request.object.get('likedPostId'),
lu : request.user.get('username'),
ca : request.object.createdAt,
pf : request.user.get('profilePicture')
}
}, {
success: function() {
console.log("push sent")
},
error: function(err) {
console.log("push not sent");
}
});
});
});

If I understand the context of where this code is correctly,
I recommend checking
if request.user.get("username") != Parse.CurrentUser.get("username")
Before sending out the push notification

Where is your cloud function being called from? If you're calling it from your ios code, then before you call the cloud code function, just prelude it with something like this:
if (PFUser.currentUser?.valueForKey("userName") as! String) != (parseUser.valueForKey("userName") as! String)

Twitter authentication in Codebird JS

I am very new to integrating social sites into a website. I somewhat managed to integrate Facebook, but I have no idea how to integrate Twitter.
I want to login through a Twitter account, then get the username and some other data from Twitter. I have a consumer key and consumer secret. I'm not sure how to proceed from here, and my Google searches haven't helped so far.
I am trying with codebird js:
$(function() {
$('#twitter').click(function(e) {
e.preventDefault();
var cb = new Codebird;
cb.setConsumerKey("redacted", "redacted");
cb.__call(
"oauth_requestToken",
{ oauth_callback: "http://127.0.0.1:49479/" },
function (reply, rate, err) {
if (err) {
console.log("error response or timeout exceeded" + err.error);
}
if (reply) {
// stores it
cb.setToken(reply.oauth_token, reply.oauth_token_secret);
// gets the authorize screen URL
cb.__call(
"oauth_authorize",
{},
function (auth_url) {
window.codebird_auth = window.open(auth_url);
}
);
}
}
);
cb.__call(
"account_verifyCredentials",
{},
function(reply) {
console.log(reply);
}
);
})
});
But I get
Your credentials do not allow access to this resource
How can I resolve this and get the user data? I am open to using an alternate Twitter implementation.

You cannot call cb._call( "account_verifyCredentials"... there.
The code only has a request token, NOT an access token, which you will only receive after the user authorizes your app (on the Twitter auth popup).
You are using the "callback URL without PIN" method, as documented on the README. So you'll need to implement that example code on your http://127.0.0.1:49479/ page.
Also, this essentially requires that you store the oauth credentials somewhere. In my example below, I've used localStorage.
$(function () {
$('#twitter').click(function (e) {
e.preventDefault();
var cb = new Codebird;
cb.setConsumerKey("CeDhZjVa0d8W02gWuflPWQmmo", "YO4RI2UoinJ95sonHGnxtYt4XFtlAhIEyt89oJ8ZajClOyZhka");
var oauth_token = localStorage.getItem("oauth_token");
var oauth_token_secret = localStorage.getItem("oauth_token_secret");
if (oauth_token && oauth_token_secret) {
cb.setToken(oauth_token, oauth_token_secret);
} else {
cb.__call(
"oauth_requestToken", {
oauth_callback: "http://127.0.0.1:49479/"
},
function (reply, rate, err) {
if (err) {
console.log("error response or timeout exceeded" + err.error);
}
if (reply) {
console.log("reply", reply)
// stores it
cb.setToken(reply.oauth_token, reply.oauth_token_secret);
// save the token for the redirect (after user authorizes)
// we'll want to compare these values
localStorage.setItem("oauth_token", reply.oauth_token);
localStorage.setItem("oauth_token_secret", reply.oauth_token_secret);
// gets the authorize screen URL
cb.__call(
"oauth_authorize", {},
function (auth_url) {
console.log("auth_url", auth_url);
// JSFiddle doesn't open windows:
// window.open(auth_url);
$("#authorize").attr("href", auth_url);
// after user authorizes, user will be redirected to
// http://127.0.0.1:49479/?oauth_token=[some_token]&oauth_verifier=[some_verifier]
// then follow this section for coding that page:
// https://github.com/jublonet/codebird-js#authenticating-using-a-callback-url-without-pin
});
}
});
}
})
});
Also made a JSFiddle

angularjs message binding doesn't show until second form submit [duplicate]

This question already has an answer here:
How come Angular doesn't update with scope here?
(1 answer)
Closed 8 years ago.
I'm writing my first angularjs app, and it's beginning to make sense. However, I have a sign up form that isn't getting the messages in some cases to alert users to problems. I'm using Firebase to authenticate, which works fine. But I'm storing users by a unique username as the key. So before I run the $createUser function, I do a quick query to see if there's already a user object with this key-- if not, I create the user.
The problem is when there is an existing user with this username. The console log value prints fine, but the error message (bound to $scope.authMsg) doesn't show up the first time-- but if I click the "register" button again, then the message shows up in the expected message div.
Any hints on the message issue (or suggestions for this code) would be appreciated!
$scope.register = function() {
$scope.authMsg = '';
var ref = new Firebase(FIREBASE_URL);
$scope.authObj = $firebaseAuth(ref);
// check if the username is taken
ref.child("/users/"+$scope.account.username).on("value", function(snapshot) {
if (snapshot.val()) {
//
// PROBLEM HERE!!
//
$scope.authMsg = 'Username exists-- did you forget your password?'; // doesn't show on page until second submit
console.log('Username exists-- did you forget your password?'); // prints to console as expected
} else {
$scope.authObj.$createUser({ email: $scope.account.email, password: $scope.account.password })
.then(function(userData) {
console.dir(userData);
return $scope.authObj.$authWithPassword({
email: $scope.account.email,
password: $scope.account.password
});
}).then(function(authData) {
// we created a user and are now logged in-- store user info
var userdata = {};
userdata[$scope.account.username] = {
uid: authData.uid,
first_name: $scope.account.first_name,
last_name: $scope.account.last_name,
email: $scope.account.email,
full_name: $scope.account.first_name+' '+$scope.account.last_name
};
var usersRef = ref.child("users");
// save the userdata
usersRef.set(userdata);
console.log("Logged in as:", authData.uid);
$state.go('app.dashboard');
}).catch(function(error) {
$scope.authMsg = error;
console.error("Error: ", error);
});
}
}, function (errorObject) {
$scope.authMsg = 'The read failed: ' + errorObject.code;
console.log('The read failed: ' + errorObject.code);
});
};

I'm assuming, the Firebase callback does not involve an angular digest cycle.
To handle this, write
if (snapshot.val()) {
$scope.$apply(function() {
$scope.authMsg = 'Username exists— did you forget your password?';
});
