Arguments disappear from the dictionary when passing a function

Question

In my function, I read user data from a session and save it in a dictionary. Then I send it to the register function from register.backend, but the function is somehow empty and a KeyError is thrown. Where did my data go? The code of the function that calls the register function:

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(userdata)

And a register function (all source here: http://bitbucket.org/ubernostrum/django-registration/src/tip/registration/backends/default/ init .py ):

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

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

Debugging after calling them:

2010-07-09 19:24:35,020 DEBUG [e-mail]
2010-07-09 19:24:35,020 DEBUG {'password1': u'a', 'email': u'[e-mail]'}
2010-07-09 19:24:35,020 DEBUG <registration.backends.default.DefaultBackend object at 0x15c6090>
2010-07-09 19:24:35,021 DEBUG backend.register
2010-07-09 19:24:35,021 DEBUG {}

Why may data be missing? Am I doing something wrong?

@edit for silent-ghost

 register() takes exactly 2 arguments (3 given)

 112.  backend = request.session['backend']
 113. logging.debug(backend)
 114. user = backend.register(request, userdata) 

Answer 1

** register. , , - register:

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']

Answer 2

:

• request

- :

backend.register(request, **userdata)

, register backend.

Answer 3

it works great

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'[e-mail]'}
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)
