How can i redirect a form to amother page when validation is correct

[Okorie Emmanuel]

Am trying to build an application that user can login to register  using pin and serial number from a scratch card, a valid pin and serial number should take a user to the registration page to create an account, here are codes i have writen 

view.py

def index(request, template_name="index.html"):

    errors=[]

    if request.method == "POST":

        form = PinForm()

        if form.is_valid():

            #form.save()

            #form.cleaned_data

            pin1 = request.POST.get('pin', '')

            serial_no1 = request.POST.get('serial_no', '')

            accept = auth.authenticate(pin=pin1, serial_no=serial_no1)

            if accept is not None and accept.is_active:

        # Correct password, and the user is marked "active"

                auth.login(request, accept)

        # Redirect to a success page.

                return HttpResponseRedirect('/acceptance/')

            

    else:

        form = PinForm()

        #accept = authenticate(pin != pin, serial_no !=serial_no, is_valid = False )

        #errors.append('This card Does Not Exist')

 #       form = PinForm()

    return render_to_response(template_name, locals(),context_instance = RequestContext(request))

def acceptance(request, template_name = "acceptance.html"):

    return render_to_response(template_name, locals(),context_instance = RequestContext(request))

form.py

from django import forms

from you.models import Pin

class PinForm(forms.ModelForm):

    class Meta:

        model = Pin

        exclude = ('is_active',)

        

urls.py

from django.conf.urls.defaults import *

urlpatterns = patterns('you.views',

            (r'^$','index', {'template_name': 'index.html'}, 'home_page'),

            #(r'^acceptance/$',{'template_name': 'acceptance.html'}, 'acceptance'),

            (r'^acceptance/$', 'acceptance', {'template_name': 'acceptance.html'}, 'acceptance'),

and 

models.py

from django.db import models

from django.forms import ModelForm

class Pin(models.Model):

    pin = models.CharField(max_length=12)

    serial_no = models.CharField(max_length=12)

    is_active = models.BooleanField(default=True)

    

    class Meta:

        db_table = 'db_Pin'

        ordering = ['pin']

        def __unicode__(self):

            return self.pin      

              

In the model i have actually stored the pin and serial no, but each time i entered a valid pin and serial number it does not redirect to the next page which for now

is the acceptance page, this i intend to change to the registration page. pls what have i not done right, pls help me fix this. thanks

It's not redirecting because the following statement never evaluates to True:

if accept is not None and accept.is_active:

You are using auth.authenticate (see below) but I don't think that's what you want in this case. auth is the built in django auth system which your code isn't using.

accept = auth.authenticate(pin=pin1, serial_no=serial_no1)

It looks like you're instead trying to load a Pin object.

Try this instead:

accept = Pin.objects.get(pin=pin1, serial_no=serial_no1)

Now accept is holding the Pin object (assuming it found one) and you can check that object for the property is_active

(remember to import Pin).

thanks for your help

 the from redirected when i used
accept = Pin.objects.get(pin=pin1, serial_no=serial_no1)

but again i discover that a user can view the accept page by typing it on his or her url
without following the normal process of entering pin and serial no first

how can i stop this, how can i force a user to see that accept page only
when he/she is comes only from the main form page, what i mean a user
can only be redirected to the accept page only when he has the valid credentials
otherwise he/she cannot view the accept page even if he entered the correct url
on his browser. thanks
