If you are using django.core.auth then it's done by default.

My project require to have my own table for users and roles. Am not using the default auth table. It becomes a problem on how i can authenticate and encrypt the password as well as maintain the session of logged in users.

Thanks in advance.

Regards

Denis.

You can use the same method that django uses I've tried it and it
works
in your model inside the class for example users and after the
definitions of the fields
write


def save(self):
raw_password = self.password
import random
algo = 'sha1'
salt = get_hexdigest(algo, str(random.random()), str
(random.random()))[:5]
hsh = get_hexdigest(algo, salt, raw_password)
password = '%s$%s$%s' % (algo, salt, hsh)
self.password = password
super(yourclass,self).save()


or there is another method like this.

but I don't like so much

def _get_ssn(self):
enc_obj = Blowfish.new( settings.SECRET_KEY )
return u"%s" % enc_obj.decrypt( binascii.a2b_hex
(self.password) ).rstrip()

def _set_pass(self, ssn_value):
enc_obj = Blowfish.new( settings.SECRET_KEY )
repeat = 8 - (len( ssn_value ) % 8)
ssn_value = ssn_value + " " * repeat
password = binascii.b2a_hex(enc_obj.encrypt( ssn_value ))
return password

sspass = property(_get_ssn)

def save(self):
self.password = self._set_pass(self.password)
super(Usuario,self).save()


with the last method you need to add this from Crypto.Cipher import
Blowfish
and you have to install Crypto.Cipher.

I hope you solve your problem

Does this work for your additional user info?

Nah;
Here is my Model.
class Title(models.Model):
    name = models.CharField(max_length=10)
   
    def __unicode__(self):
        return self.name

class UserProfile(models.Model):
    title = models.ForeignKey(Title)
    address = models.TextField()
    date_added = models.DateTimeField()

class UserProfileForm(ModelForm):
    username=forms.CharField(label=("User Name"), max_length=100)
    password_Confirm=forms.CharField(label=("Confirm Password"), widget=forms.PasswordInput,max_length=100)
    first_name=forms.CharField(label=("First Name"), max_length=100)
    last_name=forms.CharField(label=("Last Name"), max_length=100)
    date_added=forms.DateField()
    class Meta:
        model = UserProfile

here is my view.py

from django.contrib.auth import authenticate, login
from django.http import HttpResponse
from django.shortcuts import get_object_or_404
from django.shortcuts import get_list_or_404
from django.template import loader, Context
from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect
from commTrack.commtrack.models import *

def UserProfileEditor(request, id=None):
    form = UserProfileForm(request.POST or None,
                       instance=id and UserProfile.objects.get(id=id))

    # Save new/edited User
    if request.method == 'POST' and form.is_valid():
        form.save()
        return HttpResponseRedirect('/commTrack/userProfile/list/')

    return render_to_response('userProfile/adduserProfile.html', {'form':form})

and here is my form.html

<form {% if has_file_field %}enctype="multipart/form-data" {% endif %} action="{{ form_url }}" method="post" id="{{ opts.module_name }}_form">{% block form_top %}{% endblock %}

    </form>

It does not save anything when i click the submit button and it remains on the same interface. Any ideas?
