gakusei_spec の記述(destroy と show)

1. spec/requests/kurasus/gakusei_spec.rb を修正する．

describe 'DELETE #destroy' do
  context 'owned object' do
    subject { -> { delete kurasu_gakusei_path(kurasu, object) } }
    it_behaves_like :response_status_check, 302
    it_behaves_like :decrement_object_by_destroy, Gakusei
    it_behaves_like :redirect_to
    it_behaves_like :flash_notice_message, '学生を削除しました．'
  end

  context 'now owned object' do
    subject { -> { delete kurasu_gakusei_path(kurasu, not_mine) } }
    it_behaves_like :response_status_check, 302
    it_behaves_like :redirect_to
    it_behaves_like :flash_alert_message, '学生を削除する権限がありません．'
  end
end

describe 'GET #show' do
  context 'owned object' do
    subject { -> { get kurasu_gakusei_path(kurasu, object) } }
    it_behaves_like :response_status_check, 200
    it_behaves_like :response_body_includes, %w[学生表示: foo]
  end

  context 'now owned object' do
    subject { -> { get kurasu_gakusei_path(kurasu, not_mine) } }
    it_behaves_like :response_status_check, 302
    it_behaves_like :redirect_to
    it_behaves_like :flash_alert_message, '学生を表示する権限がありません．'
  end
end

gakusei_controller の記述(edit と update)

1. app/controllers/kurasus/gakuseis_controller.rb を記述する．

def destroy
  redirect_to(kurasu_gakuseis_path(@kurasu, edit_mode: true), alert: alert_message(Gakusei)) and return if @gakusei.nil?
  @gakusei.destroy
  redirect_to kurasu_gakuseis_path(@kurasu, edit_mode: true), notice: notice_message(Gakusei)
end

def show
  redirect_to(kurasu_gakuseis_path(@kurasu, edit_mode: true), alert: alert_message(Gakusei)) and return if @gakusei.nil?
end

show の view を作成

1. app/views/kurasus/gakuseis/show.html.haml を記述する．

- content_for :title do
  - @title = "#{t '.title'}: #{@gakusei.name} (#{@kurasu.name})"

guard の結果

1. guard の結果は以下のようになった

DELETE #destroy
  owned object
    behaves like response_status_check
      response should be 302
    behaves like decrement_object_by_destroy
      should change `Gakusei.count` by -1
    behaves like redirect_to
      should redirect to "/kurasus/3492/gakuseis?edit_mode=true"
    behaves like flash_notice_message
      should eq "学生を削除しました．"
  now owned object
    behaves like response_status_check
      response should be 302
    behaves like redirect_to
      should redirect to "/kurasus/3496/gakuseis?edit_mode=true"
    behaves like flash_alert_message
      should eq "学生を削除する権限がありません．"
GET #show
  owned object
    behaves like response_status_check
      response should be 200
    behaves like response_body_includes
      response body includes ["学生表示:", "foo"]
  now owned object
    behaves like response_status_check
      response should be 302
    behaves like redirect_to
      should redirect to "/kurasus/3504/gakuseis?edit_mode=true"
    behaves like flash_alert_message
      should eq "学生を表示する権限がありません．"
