Get value from push key generated-CodePudding

I want to get points of respectived logged in user to be displayed from database corresponding to its push key i tried many ways but i just couldn't make it possible here is my code

const autoid=firebase.database().ref("user").push().key;
firebase.database().ref("/").child(autoid).set({
    email :email,
    password : password, 
    points :"500", 
    Id:autoid 
})

And below is my firebase realtime database picture:

Realtime database

The following code inserts the email, password, points and ID on realtime database with different key for every user that registers and i want to show the user when he is logged in to see his email and points? I tried trying different methods but I was unsuccessful anyway to do that?

firebase.auth().createUserWithEmailAndPassword(email, password)
        .then((credential) => {
    firebase.database().ref("/users/"   credential.user.uid).set({
      email: credential.user.email,
      uid: credential.user.uid
    });
    alert("signed in");    
})

I also tried this above code to get uid as a parent file rather then getting a random push id, but I have failed to do so and I don't know where the error is the rules used for my database is:-

{
  "rules":{
    ".read": true, 
    ".write":true
  } 
}

Do I need to change the rule?

CodePudding user response：

To write the data in a node for the currently signed in user, you'd do:

const uid = firebase.auth().currentUser.uid;
firebase.database().ref("users").child(uid).set({
  email: email,
  password : password, 
  points: "500"
});

To subsequently read the data for the currently signed in user, you'd do:

const uid = firebase.auth().currentUser.uid;
firebase.database().ref("users").child(uid).once("value").then((snapshot) => {
  console.log(snapshot.val());
});
