# 211119 TIL ([Ruby, slim] 리다이렉션 하기, 버튼 클릭하면 액션 실행 link_to)

장기현장실습

PLSnote 이슈

#2644 그룹에 탈퇴신청을 하고 일정기간이 지나면 탈퇴가 되는 기능 이슈 진행중 

• 탈퇴 버튼을 클릭하면 job이 생기게 까지 구현했으니, 탈퇴 하기 버튼을 누르면 사용자에게 탈퇴 신청 취소하기 버튼이 보이게 하고, 신청 취소버튼을 누르면 job을 없애주는 cancel_withdraw가 실행되도록 구현하기 
  • Job_id가 없으면 탈퇴하기 버튼 + withdraw, 있으면 탈퇴 신청 취소하기 + cancel_withdraw 가 동작하도록 group_apply.html.slim 구현 
    • Job_id는 group_user에 있는 것을 사용해야해서 each문을 돌리는 table을 group_user로 수정

      - if current_user.group_users.present?
        - current_user.group_users.each do |group_user| 
          .card.mb-2 
            .card-body 
              .row

                  - if group_user.job_id.nil? 
                    = link_to withdraw_user_group_path(current_user.id, group_user.group.id, {group_id: group_user.group.id}), method: :post, class: 'btn btn-outline-danger' 
                      i.fa.fa-minus-circle 
                      ' #{t('.withdraw')} 
                  - else 
                    = link_to cancel_withdraw_user_group_path(current_user.id, group_user.group.id, {group_id: group_user.group.id}), method: :post, class: 'btn btn-danger' 
                      i.fa.fa-undo 
                      ' #{t('.cancel_withdraw')}

  • 버튼을 클릭하고 그 변경사항이 자동으로 바뀌기 위해서는 redirection 필요 -> group_apply 로 이동하도록 코드 추가

    def withdraw 
      job = DeleteGroupUserJob.set(wait: 60.day).perform_later(params[:group_id] , current_user.id) 
      if job
        @group_user = current_user.group_users.find_by(group_id: params[:group_id]) 
        @group_user.update job_id: job.provider_job_id 
        redirect_to group_apply_user_path 
      end  
    end 
     
    def cancel_withdraw 
      @group_user = current_user.group_users.find_by(group_id: params[:group_id]) 
      Sidekiq::ScheduledSet.new.find_job(@group_user.job_id)&.delete 
      @group_user.update job_id: nil 
      redirect_to group_apply_user_path 
    end
