[Django]-Django creating object from POST

you should be using forms[1] and model-forms [2] to collect such data from the request.

[1] http://docs.djangoproject.com/en/dev/topics/forms/

[2] http://docs.djangoproject.com/en/dev/topics/forms/modelforms/

Why would you ever do it like that anyway?

from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth import authenticate, login
from django.contrib.auth.models import User
and then handle it like that:
form = UserCreationForm(request.POST)
if form.is_valid():
    username = form.cleaned_data['username']
    password = form.cleaned_data['password1']
    email = form.cleaned_data['email']
    newuser = User.objects.create_user(username, email, password)
    user = authenticate(username=username, password=password)
    login (request, user)
    return HttpResponseRedirect('/some/page/which/is/not/logginpage')#cause user is already logged in

Probably not the most elegenat way, but it should describe well enough, how to use form and then authenticate someone & log him in.
