mypy --strict-optional -p polls output:

polls/models.py:8: error: Need type annotation for 'question_text'
polls/models.py:9: error: Need type annotation for 'pub_date'
polls/models.py:23: error: Need type annotation for 'question'
polls/models.py:24: error: Need type annotation for 'choice_text'

polls/views.py:45: error: "Question" has no attribute "choice_set"
polls/views.py:58: error: "Question" has no attribute "id"

I must add #type models.CharField to polls/models.py:8. Why it is necessary?
