from google.cloud import firestore

# Add a new document
db = firestore.Client()  # need to put credentials
doc_ref = db.collection(u'users').document(u'alovelace')
doc_ref.set({
    u'first': u'Ada',
    u'last': u'Lovelace',
    u'born': 1815
})

# Then query for documents
users_ref = db.collection(u'users')

for doc in users_ref.stream():
    print(u'{} => {}'.format(doc.id, doc.to_dict()))
