I am trying to test the __str__ method, and when it tries to enter my test, it My model gives the example (I think this is)

  def test_str_is_equal_to_title (self): "" "method` __str__` field should be equal to` title` "=" = = work. Work.objects.get (pk = 1) self.assertEqual (work .__ str__, work.title)
