How do I deserialize this JSON object?
import simplejson
from urllib2 import urlopen
from simplejson import loads
from django.core import serializers
content = loads(urlopen('https://graph.facebook.com/1234676502/feed').read())
content = simplejson.dumps(content,sort_keys=True, indent=4)
print content
json_serializer = serializers.get_serializer("json")()
json_serializer.deserialize(content)
While running the above python code im getting the following error:
Traceback (most recent call last):
File "/var/www/youedo/test.py", line 22, in <module>
json_serializer = serializers.get_serializer("json")()
File "/usr/local/lib/python2.6/dist-packages/django/core/serializers/__init__.py", line 63, in get_serializer

raise ImportError("Settings cannot be imported, because environment variable %s is undefined." % ENVIRONMENT_VARIABLE)
ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.
...and when I print the content it prints the JSON string correctly.
Edit:2 import simplejson from urllib2 import urlopen from simplejson import loads from django.core import serializers content = loads(urlopen('https://graph.facebook.com/1234676502/feed').read())
json_serializer = serializers.get_serializer("json")()
json_serializer.get_deserialize(content)
I put this code in my view.py then i got the following error:
AttributeError at /rss
'Serializer' object has no attribute 'get_deserialize'
Request Method: GET
Request URL: http://127.0.0.1:8000/rss
Django Version: 1.2.4
Exception Type: AttributeError
Exception Value:
'Serializer' object has no attribute 'get_deserialize'
Your error has nothing to with json per se, it clearly states that it cannot import DJANGO_SETTINGS
which means that you do not have the django app context in place. The easiest way to go about this is install django extensions which provides the command ./manage.py runscript
which runs your script with your django app context.
Django extensions can be found here
Edit:: looking at your second edit, I can see that you are using a method get_deserialize()
, the right method should be deserialize()
, AFAIK.
