Problem with pymongo and django unique value - django

Question

I am writing django app that as a beckend is using mongodb. I am curently writing register part. Here is how I connecto to database in settings.py
if socket.gethostname() == "Production server":
CON = Connection()
DB = CON.fish
else:
CON = Connection()
DB = CON.test
DB.user.ensure_index([("username", ASCENDING),("email",ASCENDING)],unique = True)#,drop_dups=True
Here is mye register view:
def register(request):
"""
handle user registration
code variable is for testing purposes
"""
if request.method== 'GET':
form = RegisterForm(auto_id=False)
code = 1
return render_to_response('register_home.html',locals(),context_instance=RequestContext(request))
elif request.method == 'POST':
form = RegisterForm(request.POST)
if form.is_valid():
password = form.cleaned_data['password']
password_confirmation = form.cleaned_data['password_confirmation']
if password == password_confirmation:
login = form.cleaned_data['login']
email = form.cleaned_data['email']
newsletter = form.cleaned_data['newsletter']
key = register_user(login,email,password,newsletter)
if key:
#send email
send_mail("Dziękujemy za rejestrację"," Klucz aktywacyjny to " + key,settings.EMAIL_HOST_USER,[email])
request.session['email'] = email
return redirect(register_success)
else:
code = 4
error = "Login/email taken"
return render_to_response('register_home.html',locals(),context_instance=RequestContext(request))
else:
code = 3
error = "invalid password"
return render_to_response('register_home.html',locals(),context_instance=RequestContext(request))
else:
code = 2
return render_to_response('register_home.html',locals(),context_instance=RequestContext(request))
Here is my function I use to register user:
def register_user(login,email,password,newsletter):
"""
This function will return activation key for this user if user was added successfully or none otherwise
"""
key = generate_activation_key()
user = {
"username":login,
"email":email,
"password":crypt_password(password),
"date_join": datetime.now(),
"key": key
}
if newsletter:
user['newsletter'] = True
try:
settings.DB.user.insert(user,safe = True)
except DuplicateKeyError, error:
logging.debug("error raise during saving user")
return None
except OperationFailure, error:
logging.critical("Cannot save to database")
logging.critical(error)
else:
#we have no errors users is registred
return key
And when I test it in the browser it seems to be working. But I write test for it and it isn't working anymore. Here is code for test:
def test_valid_credentials(self):
#now try to register valid user
data = {'login':'test','password':'zaq12wsx','password_confirmation':'zaq12wsx','terms':True,'newsletter':True,'email':'test#test.com'}
response = self.c.post(reverse('register'),data)
#our user should be registred
self.assertEquals(302, response.status_code,'We dont have benn redirected')
self.assertEqual(len(mail.outbox), 1,'No activation email was sent')
#clen email box
mail.outbox = []
#now try to add another user with the same data
response = self.c.post(reverse('register'),data)
#template should be rendered with error message about used login and email
self.assertEquals(200, response.status_code)#this fails
And here is error that i get.
self.assertEquals(200, response.status_code)
AssertionError: 200 != 302
So user was registred with the same username and email which shoudn't happen. Any sugestions? Thanks in advance

Why don't you use https://github.com/django-mongodb-engine/mongodb-engine it works almost perfect with Django ORM. Works like a charm for me.
