The view didn't return an HttpResponse object. It returned None instead

I have the following simple view. Why is it resulting in this error?

The view auth_lifecycle.views.user_profile didn't return an HttpResponse object. It returned None instead.

The view auth_lifecycle.views.user_profile didn't return an HttpResponse object. It returned None instead.

"""Renders web pages for the user-authentication-lifecycle project."""
from django.shortcuts import render
from django.template import RequestContext
from django.contrib.auth import authenticate, login

def user_profile(request):
"""Displays information unique to the logged-in user."""

user = authenticate(username='superuserusername', password='sueruserpassword')
login(request, user)

render(request, 'auth_lifecycle/user_profile.html',
context_instance=RequestContext(request))

Because the view must return render, not just call it. Change the last line to

render

return render(request, 'auth_lifecycle/user_profile.html',
context_instance=RequestContext(request))


I had the same error using an UpdateView

I had this:

if form.is_valid() and form2.is_valid():
form.save()
form2.save()
return HttpResponseRedirect(self.get_success_url())


and I solved just doing:

if form.is_valid() and form2.is_valid():
form.save()
form2.save()
return HttpResponseRedirect(reverse_lazy('adopcion:solicitud_listar'))


if qs.count()==1:
print('cart id exists')
if ....

else:
return render(request,"carts/home.html",{})


Such type of code will also return you the same error this is because
of the intents as the return statement should be for else not for if statement.

above code can be changed to

if qs.count()==1:
print('cart id exists')
if ....

else:

return render(request,"carts/home.html",{})


This may solve such issues
