32816	QuerysetEqual Test error on the polls app.	Hassan	nobody	"Hello.

I walk through the polls app tutorial ... I found an error in the code on part5 of the tutorial;

{{{

when i run the test i saw this error message:

So i search the web for solution and i found that on stackoverflow.com:
[https://stackoverflow.com/questions/51255851/djangos-assertquerysetequal-method-failing-despite-the-two-query-sets-printin/66696842#66696842]

The code above needs to change this way to past the test:

{{{
#!div style=""font-size: 80%""

  {{{#!python
class QuestionIndexViewTest(TestCase):

    def test_past_question(self):
        question = create_question(""Past question."", -30)
        response = self.client.get(reverse(""polls:index""))
        self.assertQuerysetEqual(
            response.context[""latest_question_list""],
            map(repr, [question]),
        )

    def test_future_question_and_past_question(self):
        question = create_question(question_text=""Past question."", days=-30)
        create_question(question_text=""Future _question."", days=30)
        response = self.client.get(reverse(""polls:index""))
        self.assertQuerysetEqual(
            response.context[""latest_question_list""],
            map(repr, [question]),
        )

    def test_two_past_question(self):
        question1 = create_question(question_text=""Past question 1."", days=-30)
        question2 = create_question(question_text=""Past question 2."", days=-5)
        response = self.client.get(reverse(""polls:index""))
        self.assertQuerysetEqual(
            response.context[""latest_question_list""],
            map(repr, [question2, question1]),
        )
    }}}
}}}

This code needs to map the second queryset with single quotation mark  to pass the test.
please correct that or if i wrong help me for better solution."	Bug	closed	Documentation	3.2	Normal	invalid	Polls, Test, QuerysetEqual		Unreviewed	0	0	0	0	0	0
