Django 反序列化

Question

I am getting the following error:

Traceback (most recent call last):
File "../tests.py", line 92, in test_single_search

for return_obj in serializers.deserialize("json",response, ensure_ascii=False):
File "/Library/Python/2.6/site-packages/django/core/serializers/json.py", line 38, in Deserializer for obj in PythonDeserializer(simplejson.load(stream), **options): File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/json/ init .py", line 264, in load return loads(fp.read(), AttributeError: 'HttpResponse' object has no attribute 'read'

In views.py the serialization works correctly:

resultsjson = serializers.serialize("json", results, ensure_ascii=False)
return HttpResponse(resultsjson, mimetype = 'application/json')

However, when I try to process the result in my calling method in test.py:

response = self.client.get("/path/?query=testValue")
for return_obj in serializers.deserialize("json", response, ensure_ascii=False):
      print return_obj

I get the above error. Has anyone come across the same error. I am using Django 1.2 (latest version from svn) and it appears to be using the in-built simplejson serializser.

You need to use response.content rather than just response in your call to deserialize . The response object is an instance of HttpResponse, but has an attribute of content which contains the actual JSON in this case.
