[英]In Django : How to serialize dict object to json?
I have this very basic problem, 我有这个非常基本的问题,
>>> 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? 如何才能做到这一点?
Also, since you seem to be using Python 2.6, you could just use the json
module directly: 此外,由于您似乎使用的是Python 2.6,因此您可以直接使用json
模块:
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: 当您在视图中使用django.core
中的序列化程序时,像json
或simplejson
这样的库对于序列化django对象来说并不是很酷:
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")
