This is my models

from django.contrib.auth.models import User
from django.db import models

class UserProfile(models.Model):

user = models.OneToOneField(User) #digunakan untuk relasi ke model User (default) alias UserProfile adalah sebagai extending model
CATEGORY_CHOICES = (
    ('admin','Admin'),
    ('user','User'),
    )
hak_akses = models.CharField(max_length=100, choices = CATEGORY_CHOICES) 
password_email = models.CharField(max_length=100, blank=True)
password_pckelas = models.CharField(max_length=100, blank=True)

# Override the __unicode__() method to return out something meaningful!
def __unicode__(self):
    return self.user.username

This is my views

def ubah_password_email(request, pk):
    #cek session
    if 'username' in request.session and request.session['hak_akses'] == 'user':
        user = get_object_or_404(User, pk=pk) #ambil id dengan get
        profile = UserProfile.objects.filter(user=user).first() 
        email_form = EmailForm(data=request.POST, instance=profile) #gunakan instance untuk mengambil data yang sudah ada
        users = User.objects.all()
        if request.POST:
            if email_form.is_valid():
                email = email_form.save(commit=False)
                email.set_password(user_profile.password_email)
                email.save()
                return redirect('home')
        else:
            email_form = EmailForm(instance=profile)

        data = {
                'email_form': email_form,
                'object_list': users,
        }
        return render(request, 'ubah_password_email.html', data)
    else:
        return HttpResponseRedirect('/simofa/logout')

1. How can i update my password_email in this case ?

I'm very grateful for your response. Thank you :)

Answer 1

So your EmailForm is returning a UserProfile model instance, and there is no function on UserProfile called set_password. I am guessing you actually want to do:

email.user.set_password(user_profile.password_email)

as the Django auth.User model does contain the set_password function.
