Question

I am using tweepy (a python lib for twitter api) to create a twitter app. Below is the django view code where I am creating an OAuthHandler with consumer key,secret and getting request token and saving it in django.messages and redirecting it to the authorization url.

Later during the callback view I am retrieving the request token and creating an OAUthHandler, but I getting this below error on ‘auth.get_access_token(v)’

TweepError at /twitter/return/

argument 2 to map() must support iteration

Traceback :
File "/usr/local/lib/python2.6/dist-packages/django/core/handlers/base.py" in get_response
111.                         response = callback(request, *callback_args, **callback_kwargs)

Exception Type: TweepError at /twitter/return/ Exception Value:

Views.py code below

def tw_return(request):
  v = request.GET.get('oauth_verifier')

  key = settings.TWITTER_KEY
  secret = settings.TWITTER_SECRET
  auth = tweepy.OAuthHandler(key, secret)

  mess = get_messages(request)

  a=[]
  for m in mess:
    a.append(m)

  auth.set_request_token(a[0],a[1])

  auth.get_access_token(v)

  api = tweepy.API(auth)
  api.update_status('tweepy + oauth1!')
  return HttpResponseRedirect('/')      

def twitter(request):
  key = settings.TWITTER_KEY
  secret = settings.TWITTER_SECRET
  auth = tweepy.OAuthHandler(key, secret)
  try:
    redirect_url = auth.get_authorization_url()
  except tweepy.TweepError:
    raise Http404

  messages.add_message(request, messages.INFO, auth.request_token.key)
  messages.add_message(request, messages.INFO, auth.request_token.secret)
  return HttpResponseRedirect(redirect_url)

Answer 1

wrong: I suspect that you are not receiving an oauth_verifier, so it’s value is None (i.e., not an iterable)

this question may help: Tweepy twitter oauth authentication not returning oauth_verifier

Here’s an example of an appEngine handler that uses tweepy, maybe it’ll help?

Final Answer:

I think you are not getting the correct request token from get_messages()… the error you are getting occurs if you call auth.set_request_token() with None. Found this in the issues on github for tweepy https://github.com/tweepy/tweepy/issues/25

# WRONG CODE
auth.set_request_token(None, None)
