Querying Firebase for objects will return a collection of data that

I need assistance with querying a Realtime Database structure for AEDs based on their owner. I want the query to return all AEDs (including children) that have a matching owner id.

Despite my efforts, I have been unable to achieve this even though it seems like it should be simple. Below is the code I am currently using:

var aedRef = dbRef.ref().child("aeds")
var query = aedRef.orderByChild("owner").equalTo(userID);
console.log(query);

Although I believe that this should work without issues, I keep getting the following output:

e {repo: e, path: e, Me: e, Le: true}

If anyone can provide some guidance or assistance, it would be greatly appreciated. Thank you!

Answer №1

query acts as a reference to a document and does not provide the query results directly. To retrieve data, you must utilize either .on or .once methods.

For detailed information on reading and writing data, refer to the Firebase documentation.

var aedRef = dbRef.ref().child("aeds");
var query = aedRef.orderByChild("owner").equalTo(userID);

// Retrieve data and listen for changes continuously
query.on('value', function(snapshot) {
  console.log(snapshot.val());
});

// Obtain data only once
query.once('value').then(function(snapshot) {
  console.log(snapshot.val());
});
