Removing a Firestore Document when the identifier is assigned to a unique name that is not predefined in any location

Presently, my database stores user information. The unique identifier for each document is the user's initial name upon registration, even though this name may have been changed at a later time without updating the document's name.

My dilemma is how to locate a document by name in order to delete it.

I attempted using 

"db.collection('Users').where('user_id', '==', this.user.uid)"

This code is successfully used elsewhere to associate authentication with user profiles, but I am uncertain how to delete the entire document as calling ".delete()" immediately after causes errors.

Does anyone have suggestions or solutions?

Answer №1

It has been clarified after your comment below that this.user.uid is not the id of the Firestore document

Therefore, you will need to execute a query and once you have the query result (using the then() method), delete the specific document returned by the query. Here is an example of how to do this:

var query = db.collection('Users').where('user_id', '==', this.user.uid);

query.get()
.then(function(querySnapshot) {
    var docSnapshot = querySnapshot.docs[0];   
    docSnapshot.ref.delete();
});

You do not necessarily have to utilize a Query for this purpose. Instead, you can directly reference the document (create a DocumentReference) and invoke the delete() method like so.

db.collection('Users').doc(this.user.uid).delete();
