There is no problem in the code. Look again at the quote and typos in the
form class. and do a trial with this view:
from django.shortcuts import render
from django.http import HttpResponseRedirect
from .forms import CommentForm
def my_view(request):
if request.method == 'POST':
form = CommentForm(request.POST)
if form.is_valid():
return HttpResponseRedirect('/thanks/')
else:
form = CommentForm()
return render(request, 'index.html', {'comment_form': form})
