SignUp후 다음과 같은 오류 메세지가 뜹니다 Reverse for 'hello_world' not found. 'hello_world' is not a valid view function or pattern name.

강의는 대략 도커파일 작성 쯤입니다만, hello_world를 삭제한 강의 이후쯤부터 잘못된것 같습니다.

SignUp에서 id와 pw를 입력하면,

Reverse for 'hello_world' not found. 'hello_world' is not a valid view function or pattern name. 

라는 오류 메세지가 뜨네요.

url 패턴을 정의할 때, pattern name을 지정하지 않아서, url reverse 시에 해당 패턴을 찾지못한다는 오류로 알고있습니다.

어디가 틀렸을까요?

그 hello world 함수를 강좌대로 삭제한게 맞았고, 같은 코드를 작성했다고 믿었는데 저는 오류메세지가 뜨네요 ㅜㅜ

해결을 위해 커뮤니티에 'reverse'라는 키워드로 질문 검색해봤는데,

같은 오류지만 원인이 다른 것 같습니다.
