IntegrityError at /clinic_management/patients/1/medhistory/ NOT NULL constraint failed: clinic_management_medical_history.patient_id

Я пытаюсь создать приложение, которое хранит медицинские записи пациентов. Я пытаюсь получить информацию о пациенте, но столкнулся с проблемой.

Когда дело доходит до размещения истории болезни, я получаю следующую ошибку:

"IntegrityError at /clinic_management/medhistory/ NOT NULL constraint failed: clinic_management_medical_history.patient_id"

Заранее благодарен за любую помощь.
