getDocParentId?

[pnaylor]

It seems like it would be very helpful for working with subcollections if there was a function in the API to fetch the parent ID of a document, unless there is already some easier way to do this that I am not aware of yet.

Thank you!

Hey, sorry for the long response. There's no easy way atm, but it should be easier to add. Right now you can parse the collection's path. You can access it via someDoc.ref.collection.path.

I see ok, thank you for the feedback.

You're welcome. I'd like to keep the issue open, so I won't forget to add it.

I found this tip useful!

The path looks like this for a document in a subcollection named thisCollectionName:
'parentCollectionName/parentDocumentId/thisCollectionName'

A simple .split('/') does wonders here :)

Is there any progress? It would be good to have ref.parentRef (which uses .split('/') to obtain the parent and a ref.getParent to get the typed parent.

@tianhuil hey! There has been no progress on the issue; however, it has become possible with the new v10 API. I will work on it when I have a chance.
