У меня возникла проблема во время почтового запроса в Django

/ 01 июня 2019

Я хочу отправить свои данные через почтовый запрос. Я использовал базу данных postgres.

Я также пытался выполнить makemigrations и перенести эту модель, также отображается сообщение об ошибке.

Когда я пытался отправить свою форму, она показывает следующую ошибку. 

IntegrityError at /formSubmit
null value in column "id" violates not-null constraint
DETAIL:  Failing row contains (Own, Khar, 3, 23, 2323, 23233, 324, null).
Request Method: POST
Request URL:    http://127.0.0.1:8000/formSubmit
Django Version: 2.1.7
Exception Type: IntegrityError
Exception Value:

мой файл models.py поставляется из команды python manage.py inspectdb. Я управлял базой данных в postgres. Файл models.py находится здесь:
