No, it is correct. If the session does not have the "has_commented" key, then they have not posted a comment yet.

Then the HttpResponse shoud not be "You've already commented". Which it is (line 101). Thus my 1st report :)

But when the has_commented key doesn't exist, the then clause of the if statement is not executed...

looking at the three cases:

  • has_commented is True => request.session.get('has_commented', False) evaluates to True => user sees "You've already commented."
  • has_commented is False => request.session.get('has_commented', False) evaluates to False => user's comment is saved and they see "Thanks for your comment!"
  • has_commented key doesn't exist in session => request.session.get('has_commented', False) evaluates to False => user's comment is saved and they see "Thanks for your comment!"

Sorry, I definitely missed the point - thank you for the additional details.
