Gravatar 문제 레일 및 Devise

나는 gravits를 사용하여 gravise를 포함하는 간단한 프로필 탭을 만들려고하지만, 나는 계속 undefined method 'nil : nilClass` cant'이메일을 보내고 있습니다.Gravatar 문제 레일 및 Devise

'gravatar_for '도우미에서'@ user.email.downcase' 대신'user.email.downcase'가되어야합니까? –

Btw, 오류가있는 코드는 정확히 어디에서 오류가 발생하는지 전체 스택 추적 없이는 유용하지 않습니다. –

@ KL-7'@ user.email.downcase'를 user.email.downcase'로 변경했습니다. 같은 문제가 발생하고 스택 추적도 추가되었습니다. 감사합니다. – Tom

귀하의 prbolem은 귀하의 tab_check.html.erb에 쇼 템플릿을 렌더링하지만 사용자가 초기화되지 않은 것입니다. 쇼보기에서 부분 렌더링을 사용하면 show 액션이 실행되고 있지 않습니다. 사용자는 tab_check 액션에서도 설정해야합니다.

tab_check 작업에 @user = User.find(params[:id])을 추가하십시오.
