*****forms.py*****

class routingForm(forms.Form):
areaDigit = forms.CharField(label='areaDigit', max_length=100)
product = forms.CharField(label='product', max_length=100)
*****views.py*****
from django.shortcuts import render
from .forms import routingForm
# Create your views here.
from django.http import HttpResponse,HttpResponseRedirect
from .models import Product,Routing_Dest_Area
def get_route_list(request):
#areaDigit= request.POST.get('areaDigit', False)
#data=Routing_Dest_Area.objects.filter(areaDigit_pk=request.POST['areaDigit'])
if request.method == "POST":
#Get the posted form
routingForm = routingForm(request.POST)
if routingForm.is_valid():
areaDigit = routingForm.cleaned_data['areaDigit']
else:
MyLoginForm = routingForm()
return render(request, 'routing/test.html',{'areaDigit':areaDigit})
*****home.html*****
<form method="POST" action="{% url 'get_route_list'%}" id="routingForm" name="routingForm">

</select>
</div>

Willem Van Onsem :
You can not write routingForm = routingForm(request.POST)
since that makes routingForm
a local variable, and it is used before it is assigned.
I however strongly suggest that you write the RoutingForm
in PerlCase, so starting with an uppercase:
# app/forms.py
from django import forms
class RoutingForm(forms.Form):
areaDigit = forms.CharField(label='areaDigit', max_length=100)
product = forms.CharField(label='product', max_length=100)
Variables in the function itself, are usually written in snake_case. So then the view looks like:
# app/views.py
from django.shortcuts import render
from .forms import RoutingForm
from django.http import HttpResponse, HttpResponseRedirect
from .models import Product, Routing_Dest_Area
def get_route_list(request):
areaDigit = None
if request.method == 'POST':
#Get the posted form
routing_form = RoutingForm(request.POST)
if routing_form.is_valid():
areaDigit = routing_form.cleaned_data['areaDigit']
else:
return render(request, 'routing/test.html',{'areaDigit':areaDigit})
