Hi,

We got an error when we used API to see a quota detail, we get the following traceback:

157.99.60.167 - - [08/Mar/2016:10:13:58 +0200] "GET /api/quotas HTTP/1.1" 200 - "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:44.0) Gecko/20100101 Firefox/44.0"

TypeError: Decimal('856488698767') is not JSON serializable

json can't serialize Decimal object.
I tested it with simplejson and it works.
An other solution is to convert the Decimal object to a float before the dumps.

Thanks a lot for your help
Best regards,
