Suppose I specify a MongoDB cursor with pymongo, which DOES NOT include all fields in the result set like this:
from pymongo import MongoClient
conn = MongoClient('mongodb://localhost:27017')
cur = conn['my_db']['my_collection'].find({},{'_id' : 0, 'my_unwanted_field' : 0})
Is there a function or attribute that will return me the names of the fields present in cur.
Something equivalent on Mongo Shell using findOne would be:
> var cur = findOne({},{'_id' : 0, 'my_unwanted_field' : 0})
> Object.keys(cur)
["field_1", ... , "field_n"]
