Hovedproblemet med Django Signup urls.py er at det ikke er godt designet. Koden er rotete og vanskelig å lese, og den følger ikke beste praksis. Dette gjør det vanskelig å forstå og vedlikeholde, noe som kan føre til problemer med registreringsprosessen.
<code>urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^register/$', views.register, name='register'),
]
</code>
Code in Django: Django Signup views.py
<code>def register(request):
registered = False
if request.method == 'POST':
user_form = UserForm(data=request.POST)
if user_form.is_valid():
user = user_form.save()
user.set_password(user.password)
user.save()
registered = True

Hva er urls.py
urls.py er en modul i Django-prosjektet som hjelper til med å administrere URL-er. Det gir en praktisk måte å opprette og administrere URL-er for applikasjonene dine på, og den gir også en rekke funksjoner for å gjøre arbeidet med URL-er enklere.
Påmeldinger og innlogging
I Django håndteres registreringer og pålogging gjennom django.contrib.auth-modulen. For å opprette en ny brukerkonto, bruker du create_user()-funksjonen:
fra django.contrib.auth import create_user user = create_user(brukernavn, passord)
For å logge på en eksisterende konto, bruker du login()-funksjonen:
fra django.contrib.auth import login user = login (brukernavn, passord)
