I have this very ba开发者_如何学Csic problem,
>>> from django.core import serializers
>>> serializers.serialize("json", {'a':1})
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/usr/lib/pymodules/python2.6/django/core/serializers/__init__.py", line 87, in serialize
s.serialize(queryset, **options)
File "/usr/lib/pymodules/python2.6/django/core/serializers/base.py", line 40, in serialize
for field in obj._meta.local_fields:
AttributeError: 'str' object has no attribute '_meta'
>>>
How can this be done?
Also, since you seem to be using Python 2.6, you could just use the json
module directly:
import json
data = json.dumps({'a': 1})
from django.utils import simplejson
data = simplejson.dumps({'a': 1})
Libraries like json
or simplejson
are not really cool for the purpose of serializing django objects, when you can use the serializer from django.core
in your views:
from django.core import serializers
def json_for_model_instance(request, pk):
instance = YourModel.objects.get(pk=pk)
serialized_instance = serializers.serialize('json', [instance, ])
return HttpResponse(serialized_instance, content_type="application/json")
