DeprecationWarning: count is deprecated. Use Collection.count_documents instead.
I'm making authentication server with Python-Flask and PyMongo package. Every time post()
method is called, above deprecation warning message is displayed.
def post(self):
if db.users.find({"email": email}).count_documents() != 0:
abort(400, message="email is alread used.")
However, if I change count()
to count_documents()
, following error message comes out.
AttributeError: 'Cursor' object has no attribute 'count_documents'
How do I call count_documents()
correctly after find()
is called?
The method count_documents
is part of the collection
, not the cursor
(find
returns a cursor).
Please see the PyMongo documentation regarding the method for more information and a note regarding some operators.
