'''Context:'''
This issue has been noted when fixing
https://code.djangoproject.com/ticket/23112
'''Current behavior:'''
Using _get_FIELD_display on a Field.choices using Iterators, you will get
the first tuple value.
'''Expected behavior:'''
Expected result is to get the human-readable name in from the iterator
tuple.
'''Tests to reproduce the issue:'''
Edit `tests/model_fields/tests.py` add inside `class
ChoicesTests(test.TestCase)` the following tests:
# def test_iterator_choices_and_field_display(self):
# """
# Check that get_choices works with Iterators (#23112).
# """
# self.assertEqual(WhizIter(c=1).get_c_display(), 'val-1') # A
nested value
# self.assertEqual(WhizIter(c=9).get_c_display(), 9) #
Invalid value
# self.assertEqual(WhizIter(c=None).get_c_display(), None) #
Blank value
# self.assertEqual(WhizIter(c='').get_c_display(), '') #
Empty value
