Eliminate individuals from the Firebase database

Recently, I delved into learning more about Firebase and decided to create a basic database.

After following all the steps on the website, I successfully added members to the database.

Now, my next challenge is figuring out how to remove a user from the database.

Below is the code snippet for adding and removing users:

<!DOCTYPE html>
<html>
  <head>


  </head>
    <body>
      <button onclick="saveData()">Save Data</button>
      <button onclick="printData()">Print Data</button>
      <button onclick="printData2()">Print Data2</button>
      <button onclick="remove()">Remove</button>
      <script src="https://cdn.firebase.com/js/client/2.4.2/firebase.js"></script>
      <script>
        var ref = new Firebase("https://projecttest-9aee9.firebaseio.com/web/saving-data/fireblog");
        var usersRef = ref.child("users");
        function saveData(){
        usersRef.set({
          alanisawesome: {
            date_of_birth: "June 23, 1912",
            full_name: "Alan Turing"
          },
          gracehop: {
            date_of_birth: "December 9, 1906",
            full_name: "Grace Hopper"
          }
        });
      }
      function printData(){

        usersRef.on("value", function(snapshot) {
        console.log(snapshot.val());
      }, function (errorObject) {
        console.log("The read failed: " + errorObject.code);
      });
      }
       function printData2(){

        ref.child("users/gracehop/date_of_birth").on("value", function(snapshot) {
        console.log(snapshot.val());//"December 9, 1906"
      }, function (errorObject) {
        console.log("The read failed: " + errorObject.code);
      });
      }


      function remove(){
                  ref.removeUser({
                    alanisawesome: {
                    date_of_birth: "June 23, 1912",
                    full_name: "Grace Hopper"
                                   }

                  });
          }
      </script>
    </body>
</html>

Any insights on what's causing issues with the remove users function?

Your help is greatly appreciated!

Answer №1

Initially, the function removeUser is not defined anywhere. Additionally, it seems like there may be an issue with the ref used in remove(); you should consider using usersRef.

You might want to attempt utilizing the user.remove() method.

According to the User API reference:

This operation deletes the user account and logs them out simultaneously.

Note: this action involves sensitive security measures and can only be executed if the user has recently signed in. If this condition is not met, prompt the user to re-authenticate and then invoke firebase.User#reauthenticate.

If your intention is to remove the database node corresponding to a specific user, you could implement the following script:

usersRef.remove()
  .then(function() {
    console.log("Deletion successful.")
  })
  .catch(function(error) {
    console.log("Deletion unsuccessful: " + error.message)
  });
