사용자가 다른 사용자에게 의견을 남길 수 있도록 레일 평가 모델을 설정하는 방법을 파악하는 데 어려움이 있습니다.레일 - 연관성, 사용자 의견 - 사용자 의견 - 피드백 표시
User.rb
을 :Rails - feedback on specific users, how to set up the form to identify relevant users
내가 그로부터받은 제안은 다음과 같이 모델을 설정했다 :

내가 방법을 알아낼 수 없습니다를 사용자가 다른 사용자를 평가할 수 있도록 모델을 설정합니다. 나는 각 사용자가받은 평가를 각각의 쇼 페이지에 보여주고 싶다. 나는 무엇이 잘못되었는지 알 수 없다. 콘솔에서 사용자가 다음과 같은 평가를 받았음을 알 수 있습니다.
=> #<Evaluation id: 8, evaluatee_id: 34, overall_score: 4, project_score: 5, personal_score: 5, remark: "jhjkhjhjkhkjhjkhjhkhjhkj", work_again?: nil, continue_project?: nil, created_at: "2016-06-12 21:52:53", updated_at: "2016-06-12 21:52:53", evaluator_id: 34>
내가 작업하고있는 사용자의 항목이 있습니다. 그러나, 나는 그 평가를 보여주는 방법을 찾을 수 없습니다. @given_evaluations 및 @received_evaluations 쇼 작업에 설정되지 않는 및 주석 부분이 있으므로 이유는 없었던 하나 개의 인스턴스를 반환 할 것 ActiveRecord#find 방법을 사용하고 있습니다 : 내가 볼 수
