how to properly configure error handling in template - django

Question

I have a basic form that I'm rendering in template using standard "{{ form.name_of_field.errors }} tags. When I try to submit an empty form, I expect to see the form re-rendered with "•field is required" next to the empty form fields. What I get instead is a Value Error. "The view wedbpjr.wedb.views.display_prdInboxEntry didn't return an HttpResponse object." Where am I going wrong?
<form action="." method="POST">{% csrf_token %}
{{ form.non_field_errors }}

Answer 1

The errors is coming from your view, Make sure you have a condition for your form.is_valid equaling False. This usually involves reshowing the form with the incorrect data
from django.shortcuts import render
from django.http import HttpResponseRedirect
def contact(request):
if request.method == 'POST': # If the form has been submitted...
# ContactForm was defined in the the previous section
form = ContactForm(request.POST) # A form bound to the POST data
if form.is_valid(): # All validation rules pass
# Process the data in form.cleaned_data
# ...
return HttpResponseRedirect('/thanks/') # Redirect after POST
else:
form = ContactForm() # An unbound form
return render(request, 'contact.html', {
'form': form,
})
The django documentation, clearly explains this
