No need to mess with ** in register method. What you want to do is simply pass dictionary to register method:

user = backend.register( request, userdata ) # you need to pass request as definition says

def register( self, request, userdata ): # note lack of **
    logging.debug("backend.register")
    logging.debug( userdata ) # should work as expected

    username, email, password = userdata['email'], userdata['email'], userdata['password1']

Judging by the method’s signature:

  1. you need to unpack your dictionary
  2. you need to pass relevant request variable

Something like this:

backend.register(request, **userdata)

Assuming register is a method on backend instance.

this perfectly work

class Logging():
    def debug(self,f):
        print f
class DefaultBackend(object):
    def register(self, request, **kwargs):
        logging.debug("backend.register")
        logging.debug(kwargs)

        username, email, password = kwargs['email'], kwargs['email'], kwargs['password1']

class Request:
    def __init__(self):
        self.session = {}
request = Request()
logging=Logging()
request.session['temp_data']={'password1': u'a', 'email': u'my@email.com'}
request.session['backend']=DefaultBackend()



data = request.session['temp_data']
email = data['email']

logging.debug(email)

password1 = data['password1']
userdata = {'email': email, 'password1': password1}

logging.debug(userdata)

backend = request.session['backend']

logging.debug(backend)

user = backend.register(request,**userdata)
