I can create a new document (with auto generated ID), and store a reference to it like this:
my_data = {"key": "value"}
doc_ref = db.collection(u'campaigns').add(my_data)
I can access the data itself like:
print (doc_ref[0]) # prints {"key": "value"}
But when I try to access the doc_ref ID, I am unable to:
# All of these throw attribute errors
doc_ref.get()
doc_ref.data()
doc_ref.id
There are other posts which suggest how to do this in Javascript, but none which work for the Python SDK!
How can I access the generated ID of a document I created?
The documentation is unclear, but I finally got it to work:
doc_ref = db.collection(u'campaigns').document()
doc_ref.set(my_data)
print(doc_ref.id)
