나는이 코드를 실행하려고 할 때 주어진 뷰와 템플릿 코드를 가지고 있는데, 다음과 같은 errors.when을 검색하면이 오류 유형을 검색 할 때 변수와 함수 동일한 이름이 주어 지지만 내 코드에서이를 수정할 수는 없습니다.Django를 해결하는 방법 : UnboundLocalError

당신의 들여 쓰기 및 서식을 수정하십시오. 그리고 조금 더 오류 출력을 포함 – scytale
@scytale 내가 오류 정보를 제공하고 내게 초보자 나와 함께 코드를 들여 쓰려고했습니다 – nimeshkiranverma
보기의 들여 쓰기가 여전히 엉망입니다. 당신을 도와달라고 요청하는 사람들에게 예의 바르게 고쳐주십시오. 템플릿 변수가 제대로 설정되지 않은 것 같습니다. 'formsetlist'가 정확히 채워지는지보기 위해 print 문을 넣으십시오. – scytale
