안녕하세요 지금 자유게시판 카테고리를 만들고있습니다. 질문과답변, 자유게시판 두개의 카테고리를 만든 후 질문 등록하기 버튼을 누르면 question_create() missing 1 required positional argument: 'category_name'이와 같은 오류가 계속 발생합니다. 코드가 오류인지 계속 찾아 보았지만 도무지 모르겠습니다. 저런 오류는 어떻게 해결하나요? 도와주세요
저자님의pybo.kr과 https://velog.io/@azzurri21/Django-점프투장고-카테고리-기능-추가 을 참고하였습니다. 아래는 코드입니다.
