I created a twitter.Twitter object, but cannot store it into session. Following is my code.
t = twitter.Twitter(auth=twitter.OAuth(consumer_key, consumer_secret,
oauth_token, oauth_secret))
request.session['t'] = t
but if I store a string like
request.session['t'] = 't'
it works, why? because the twitter#Twitter object is not a serializable object? How can I avoid authenticating each time when I need a twitter#Twitter object? Following is the django trace.
