アプリケーションでアクションへの AJAX 呼び出しを行いたいのですが、ガイドAjax in Rails 3.1 - A Roadmapdestroyの例 #3 に従っています。Rails 3.2.8 を使用しています。
AJAX リクエストが正常に機能し、destroy期待どおりにアクションが呼び出されました。ユーザーがアクションの HTML ページを要求したときにdestroy、アイテムを削除してから別のページにリダイレクトしたいと考えています。
問題は、リダイレクトするコードを挿入すると、HTML と AJAX の両方のリクエストが機能しなくなることです。コードがある場合、AJAX リクエストは 500 Internal Server Error を返し、HTML リクエストは「The action 'show' could not be found for SafetyTestsController」を返します。2 つの行が存在しない場合、AJAX は正常に機能し、HTML は引き続き同じエラーを返します。
表示 (レンダリングなし):
<%= link_to 'Delete', {controller: 'safety_tests', action: 'destroy', id: safety_test.id}, remote: true, method: :delete, confirm: 'Are you sure?', id: "delete_safety_test" %>
ビュー (レンダリング):
<a href="/safety_tests/14" data-confirm="Are you sure?" data-method="delete" data-remote="true" id="delete_safety_test" rel="nofollow">Delete</a>
app/controllers/safety_tests_controller.rb
class SafetyTestsController < ApplicationController
respond_to :html, :js
...
def destroy
test = SafetyTest.find(params[:id])
student_id = test.student_id
test.destroy
respond_with(test) do |format|
format.js { render nothing: true }
end
#Two lines below should run for an HTML request but not a Javascript request.
#When uncommented, AJAX request returns 500 Internal Server Error
#flash[:notice] = 'Safety test deleted successfully.'
#redirect_to controller: 'students', action: 'show', id: student_id
end

2行を機能させるにはどうすればよいですか?
