PyMongo trouble encoding numbers

[jonhanke]

Hi,

I'm trying to use PyMongo in Sage 4.6, and am having trouble encoding
numbers in dictionary documents, though strings seem to work well.
Any comments are appreciated! Thanks,

sage: C = pymongo.Connection("localhost:29000")
sage: col = C.db_test.c_test
sage: col
Collection(Database(Connection('localhost', 29000), u'db_test'),
u'c_test')
sage: col.find_one()
sage:
sage: col.insert({ "a" : str(1)})
ObjectId('4cf12d39e1382313ae000010')
sage:
sage: col.insert({ "a" : Integer(1)})

Use int(..) instead of Integer. Mongo only encodes standard python types.

Note, however, that Mongo does not support arbitrary precision
integers, so if you need more than 64 bits than you'll have to use a
string.
