Firestore document/subcollection is not existing

Question

I have this db structure:

Firestore-root
|
--- sites (collection)
|     |
|     --- common (document)
|            |
|            --- //templates (collection         


        

Answer 1

The Firebase Console isn't indicating you that the "common" and the "other" documents are deleted. It is telling you that it just does not exist. Those documents do not exist because you didn't create them at all. What you did do, was only to create a subcollection under a document that never existed in the first place. With other words, it merely "reserves" an id for a document in that collection and then creates a subcollection under it. Typically, you should only create subcollections of documents that actually do exist but this is how it looks like when the document doesn't exist.

One thing to remember, in Cloud Firestore documents and subcollections don't work like filesystem files and directories. If you create a subcollection under a document, it doesn't implicitly create any parent documents. Subcollections are not tied in any way to a parent document.

Document ids shown in italics are not necessarily "deleted". They are shown that way because the document does not exist. With other words, there is no physical document at that location but there is other data under the location.

If you want to correct that, you have to write at least a property that can hold a value.

P.S. In Firestore, if you delete a document, its subcollections still exist.
