How to convert firestore query response to json using python

Question

I have written the following piece of code:

places_ref = db_client.collection(u'places')
doc = places_ref.where (u'city_name', u'==', 'paris').get()
print(doc)

The console output is:

If I try this:

print(u'Document data: {}'.format(doc.to_dict()))

I get the following error:

AttributeError: 'generator' object has no attribute 'to_dict'

How do I convert the query result to a dictionary?

The returned value from firestore is a generator containing many documents. Looking at the firestore docs it looks like the following is what you want,

my_dict = { el.id: el.to_dict() for el in doc }
