My document class is defined as

Answer 1

Places.objects.insert doesn't take a list of dictionaries it has to be Places instances. Normal operations would be to create individual instances of Places and save or insert eg:

Places(name="test", loc=[-87, 101]).save()
Places(name="test 2", loc=[-87, 101]).save()

However if you want to do a bulk insert you can pass a list of Places instances and call insert on the objects queryset eg:

Places.objects.insert([Places(name="test", loc=[-87, 101]), 
                       Places(name="test 2", loc=[-87, 101])])

Answer 2

You try to initialize Document object for multiple documents at once. If you look at mongoengine's BaseDocument class, you'll see, that its __init__ method takes a dictionary of keyword arguments, which relate to fields of one single document.

If you want to do a bulk save, you have to make a list of places instances and pass it to insert() method.

a = []
a.append(places(**{"name": 'test', "loc": [-87,101]}))
a.append(places(**{"name": 'test', "loc": [-88,101]}))
x = places.objects.insert(a)
