mongoengine.Document.objects is not callable

[Coldwings]

In the fake module mongoengine, the fake Document class is defined as

from mongoengine.errors import DoesNotExist, MultipleObjectsReturned

class Document(object):
    _meta = None
    objects = None

    id = None
    pk = None

    MultipleObjectsReturned = MultipleObjectsReturned
    DoesNotExist = DoesNotExist

    save = lambda: None

which member objects gives a None. The fact in mongoengine it should be a mongoengine.QuerySetManager, which is callable, and can be used as query method.

For now, the code
SomeDocument.objects(query)
pylint gives out a E1102. That should be fixed.
