I have the following ListView
import json
class CountryListView(ListView):
model = Country
def render_to_response(self, context, **response_kwargs):
return json.dumps(self.get_queryset().values_list('code', flat=True))
But I get following error:
[u'ae', u'ag', u'ai', u'al', u'am',
u'ao', u'ar', u'at', u'au', u'aw',
u'az', u'ba', u'bb', u'bd', u'be', u'bg',
u'bh', u'bl', u'bm', u'bn', '...(remaining elements truncated)...']
is not JSON serializable
Any ideas ?
class CountryListView(ListView):
model = Country
def render_to_response(self, context, **response_kwargs):
return HttpResponse(json.dumps(list(self.get_queryset().values_list('code', flat=True))),mimetype="application/json")
fixed the problem
also mimetype is important.
