[bottlepy] returning objects as JSON in bottle

[Daniel Watrous]

Hello,

I have a list of objects that I want converted to json at the time the
response is sent. I found this
(https://github.com/bottlepy/bottle/issues/287), but I can't seem to get it
working.

class MyJsonEncoder(json.JSONEncoder):
def default(self, obj):
if isinstance(obj, model.person):
return obj.__dict__
return json.JSONEncoder.default(self, obj)

appv1 = bottle.Bottle(autojson=False)
appv1.install(bottle.JSONPlugin(json_dumps=lambda s: json.dumps(s,
cls=MyJsonEncoder)))

@appv1.get('/v1.0/person/search')
def search_people():
bottle.response.content_type = 'application/json'
search, city, country = get_person_search_attributes()
matching_people = persondao.find_by_last_first_comma(search, city,
country)
return matching_people

When i "return matching_people" I am expecting it to be run through
MyJsonEncoder.default. If the obj is an instance of "model.person" it
should return a dict. The default function doesn't appear to ever get
called.

What am I missing?

I found this interesting article about flask:
http://flask.pocoo.org/docs/0.10/security/#json-security

It seems to apply to bottle too. If I change my last line to this

return {'result': matching_people}

It begins working. That's not quite what I was hoping to accomplish, but it
gives me something to work with.

Sample[1]

import json
from bottle import response

response.set_header('charset', 'utf-8')
response.content_type = 'application/json'
data = {'a': 1, 'b': 2}
return json.dumps(data)
