Question

I have just started learning django. I created a form from django models. On the click of submit button the data is getting stored in database. Now what i want is something like the one given below :

#view.py
def contact(request):
  if request.method == 'POST':
  form = UserForm(request.POST)
  if form.is_valid():
            user = form.save()
            return HttpResponseRedirect("/contact/create_db")

#urls.py
(r'^contact/$', views.contact),
(r'^contact/create_db$', views.do_create),

Now when i define do_create function in views.py i want to pass the arguments(user data of user form) like this:

def do_create(request, password, dbname, admin_password, confirm_password, demo_data=False, language=None, **kw):

Is this possible using django. How can this be achieved.

Answer 1

All you’re asking here is how to get the value of the saved user in a subsequent view.

Well, this is easy. Once the user is saved, it (like any model instance) gets a pk value. You can use this in the URL for the subsequent view.

url(r'^contact/create_db/(?P<user_id>\d+)/$', views.do_create, 'do_create'),

In contact:

from django.shortcuts import redirect

...

user = form.save()
return redirect('do_create', kwargs={'user_id': user.pk})

And in do_create:

def do_create(request, user_id):
    user = User.objects.get(pk=user_id)

Note the way I’ve passed in the URL name and arguments into redirect, rather than hard-coding the URL.
