python firebase query by document ID

Question

If I want to query firebase documents under specific collection, how can I skip query some of document ID?

What I expected was

from firebase_admin import firestore

db = firestore.client()
skip_id = ["3zbBeHVvMY2aSfUM2mSL", "Xsa4cJOkIZbMkuYEGrLd", "kePiLfd7f9Lx99hSV9FM"]
docs = db.collection('my_collection').where("id", "not in", skip_id)

but it seems the above code is not working.

Answer 1

Your .where("id", "not in", skip_id) means that you're filtering on a field named id in the document data, not on the document ID.

If you want to filter on the document ID, you can use the special "__name__" marker, or with firestore_v1.field_path.FieldPath.document_id() .

• The documentation on FieldPath
