레일 웨이 4에서 carrierwave와 중첩 된 형식을 사용하여 파일을 업로드하려면 어떻게해야합니까?

Question

안녕하세요. 파일을 업로드하는 중에 문제가 있습니다. 저는 carrierwave를 사용하여 파일을 업로드하고 중첩 된 양식을 사용하여 사용자로부터 파일을 캡처합니다. 페이지를 제출하면 모든 것이 제대로 작동하지만 파일이 업로드되거나 데이터베이스에 저장되지 않습니다. https://gist.github.com/jpstokes/10276415

은 서버 로그에 따라 경찰, 경고 Unpermitted parameters: resumes_attributes, job_id있다.

여기에서해야 할 일은 ApplicantsController의 resumes_attributes 및 job_id 허가입니다.

def applicant_params 
    params.require(:applicant).permit(:fname, :lname, :phone,..., resumes_attributes: [:name, :attachment,...]) 
    end
