I'm trying to update/add data on firebase. I used the Facebook login and I want to use the UserID as a key for the new data aded.
(check pict below)
The userID that I want to use it:
I want to replace that key with the userID:
fblogin(){
this.facebook.login(['email'])
.then(res=> {
const fc = firebase.auth.FacebookAuthProvider.credential(res.authResponse.accessToken);
firebase.auth().signInWithCredential(fc)
.then(fs => {
this.facebook.api('me?fields=id,name,email,first_name,picture.width(720).height(720).as(picture_large)', []).then(profile => {
this.newuser = {name: profile['first_name'] ,email: profile['email'],picture: profile['picture_large']['data']['url'],phone:''}
this.navCtrl.push(HomePage);
console.log(fs.uid);
this.db.list('/users/'+ fs.uid).update(this.newuser);
});
I got this error in compilation:
supplied parameters do not matchany signature of call target
In this line: this.db.list('/users/'+ fs.uid).update(this.newuser);
Any help?
The FB error looks correct. You cant update on the uid
as the user has been saved with a unique FB id
You do not show the code that created the users
record in the database, but what i think you want to do is set and object when you first save the users
record. However this could be an issue because the user
could be saved before the return of the uid
. I cant tell with your code snippet. Regardless, I will write the code that i think will work if the users/
record is created at the time that of registration.
The service
async signupUser(email: string, password: string) {
try {
const result = await this.afA.auth.createUserWithEmailAndPassword(email, password);
return result;
} catch (err) {
console.log('error', err);
}
}
So this initially creates a user without facebook, The key here is that the users FB uid
was created and is held in the returned result
The component
this.authData.signupUser(email,password).then(userData => {
console.log(userData) // <- this is result
}
Then we create a record in FB with the uid
returned
this.db.object(`users/${userData.uid}/`).set(data);
.set(data)
is whatever data you want to save in the users/uid
namespace.
So basically you need to create that user table with its uid
namespace when the user first registers. Then you can update the user with the uid
returned from the facebook fs.uid
With your current code you could find
the user based on the email ( because the email should be unique to all users) and then update ...
with lodash is it just
let foundUser = find(this.db.list('users'),{ 'email' : fs.email }
// and then update based on the object key
this.db.list('/users/'+ Object.keys(foundUser)).update(this.newuser);
i fixed the problem by using:
this.db.object('/users/'+ fs.uid).update(this.newuser);
instead of :
this.db.list('/users/'+ fs.uid).update(this.newuser);
And it works correctly ! Thanks all for help.
