Python is very sensitive to indentation  with the code below I got the same error      except IntegrityError as e          if  unique constraint  in e args              return render request   quot calender html quot    The correct indentation is      except IntegrityError as e          if  unique constraint  in e args          return render request   quot calender html quot

Because the view must return render  not just call it  Change the last line to  return render request   auth lifecycle user profile html              context instance RequestContext request

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

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