HTTP 500 error on POST - django

Question

I am following instructions from here How can I login to django using tastypie to create a UserResource that can be used to login to my django user.
However, I am running into HTTP 500 error when I run the code. I tried to debug it myself, but could not figure it out. I am not sure how I can troubleshoot the 500 error. Any thought you can give is appreciated.
Thanks!!
My code is as below:
#####api.py
from registration.views import register
from tastypie.resources import ModelResource
from tastypie.constants import ALL
from django.contrib.auth.models import User
from django.contrib.auth import authenticate, login, logout
from tastypie.http import HttpUnauthorized, HttpForbidden
from django.conf.urls.defaults import url
from tastypie.utils import trailing_slash
class UserResource(ModelResource):
class Meta:
queryset = User.objects.all()
fields = ['first_name', 'last_name', 'email']
allowed_methods = ['get', 'post']
resource_name = 'user'
def prepend_urls(self):
return [
url(r"^(?P<resource_name>%s)/login%s$" %
(self._meta.resource_name, trailing_slash()),
self.wrap_view('login'), name="api_login"),
url(r'^(?P<resource_name>%s)/logout%s$' %
(self._meta.resource_name, trailing_slash()),
self.wrap_view('logout'), name='api_logout'),
]
def login(self, request, **kwargs):
self.method_check(request, allowed=['post'])
print "reached login auth"
data = self.deserialize(request, request.raw_post_data, format=request.META.get('CONTENT_TYPE', 'application/json'))
username = data.get('username', '')
password = data.get('password', '')
print "reached login auth"
user = authenticate(username=username, password=password)
if user:
if user.is_active:
login(request, user)
return self.create_response(request, {
'success': True
})
else:
return self.create_response(request, {
'success': False,
'reason': 'disabled',
}, HttpForbidden )
else:
return self.create_response(request, {
'success': False,
'reason': 'incorrect',
}, HttpUnauthorized )
def logout(self, request, **kwargs):
self.method_check(request, allowed=['get'])
if request.user and request.user.is_authenticated():
logout(request)
return self.create_response(request, { 'success': True })
else:
return self.create_response(request, { 'success': False }, HttpUnauthorized)
########test_login.py
import requests
import json
from urllib2 import urlopen
import datetime
import simplejson
url = 'http://127.0.0.1:8000/api/user/login'
data = {'username' :'sv3#gmail.com', 'password' : 'pass'}
headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
print json.dumps(data)
r = requests.post(url, data=json.dumps(data), headers=headers)
print r
#####urls.py
from userdetails.api import UserResource
user_resource = UserResource()
urlpatterns = patterns('',
......
(r'^api/', include(user_resource.urls)),
)

When deploying via WSGI using print statement can raise IOErrors. Try to comment them out or redirect the output.
In Django, how do I allow print statements to work with Apache WSGI?

Append a slash
url = 'http://127.0.0.1:8000/api/user/login/'
