#151 Rack Middleware - RailsCasts
Resources Rack rack-contrib Full Episode Source Code Special thanks to Josh Peek for answering some questions I had on this topic. Update: making the code below thread safe by duplicating self on call. Note: as wldock and remi pointed out in the comments, it is important to change the headers["Content-Length"] value to reflect the new body length. See their comments for details.
#274 Remember Me & Reset Password - RailsCasts
Although there are a number of good available authentication solutions for Rails applications there’s still a lot to be said for rolling your own. In episode 250 [watch, read] we did exactly that and later, in episode 270 [watch, read], we showed how Rails 3.1 makes it even easier by giving us has_secure_password which will automatically generate password hashes. The authentication we implemented
#134 Paperclip - RailsCasts
Below is a page for a product in an e-commerce application. We’d like to add an image of the product to this page and modify the admin system so that an image can be uploaded when a product is created or modified. In this episode we’ll show you how to use a plugin called Paperclip to do this. Paperclip makes adding attachments to a model simple. We’re going to use it to add a field to our Product

#254 Pagination with Kaminari - RailsCasts
The first-choice gem for pagination in Rails is will_paginate, but the currently released version doesn’t support Rails 3. There is a pre-release version available that works but it hasn’t been updated for several months. If will_paginate is no longer in active development are there any other gems we could use? One alternative is Kaminari. This seems to provide a cleaner implementation of paginati
#23 Counter Cache Column - RailsCasts
If you need to display the record count for a has_many association, you can improve performance by caching that number in a column.
#270 Authentication in Rails 3.1 - RailsCasts
HTTP Basic Authentication We want to add authorization to this page so that it can only be accessed by certain users. For this we need to add some authentication and the quickest way to add this is to add HTTP Basic authentication. Rails 3.1 gives us a new way to do this; all we need to do is to modify the page’s controller and add a call to a new method called http_basic_authenticate_with which t
#257 Request Specs and Capybara - RailsCasts
ハイレベルテストは、Railsアプリケーションをテストする優れた方法です。この種のテストでよく用いられるCucumberについて、エピソード155[動画を見る, 読む]で取り上げました。Cucumberの、アプリケーションの振る舞いを英語の文法で定義するやり方が好きではない人もいるでしょう。そこで今回はハイレベルテストを実行する別の方法を見てみます。 普段はテスト駆動開発を奨励していますが、今回はすでに完成したアプリケーションにテストを追加することにします。それによって、実装の詳細やアプリケーションが正常動作するかどうかに気をとられることがなくなります。これからテストを追加するアプリケーションは、単純な１ページのみのTo Doリストです。タスクのリストを表示し、新規タスクを追加するためのフォームがあります。
