Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

サバクラ両方で動く JavaScript の大規模開発を行うために

考えてみれば Model-View-Controller とか MVC ってよく聞くよね。実際どんなものか知ってる？抽象的に言うなら「オブジェクト情報の保持されるグラフィック・システム (つまり、ラスターではないグラフィック。ゲームとか) 上に構築された、表示系を中心としたアプリケーションにおいて、主要な機能どうしの関わりをうまく分離すること」とでも言おうか。もう少し深く考えを押し進めてみれば、これは当然、他のさまざまなアプリケーションにもあてはまる言葉 (bucket term ?) だ。

過去に多くの開発コミュニティが MVC による解決案を提供し、それによってよくあるユースケースにうまく対処し、地位を築くことができた。例をあげるなら、Ruby や Python コミュニティは Rails や Django を作り、MVC アーキテクチャを実現した。

ruby-debugを使ったRuby・Railsアプリケーションのデバッグ方法

インストール

# Ruby 1.8系の場合
gem install ruby-debug

# Ruby 1.9系の場合
gem install debugger

To run this, you can try:

curl -ksO https://gist.githubusercontent.com/nicerobot/2697848/raw/uninstall-node.sh
chmod +x ./uninstall-node.sh
./uninstall-node.sh
rm uninstall-node.sh

	connection = Faraday.new 'http://example.com'

	# GET
	connection.get '/posts'

	class ApplicationController < ActionController::Base

	...
	#Problem:
	#In rails 3.0.1+ it is no longer possible to do this anymore;
	# rescue_from ActionController::RoutingError, :with => :render_not_found
	#
	#The ActionController::RoutingError thrown is not caught by rescue_from.
	#The alternative is to to set a catch-all route to catch all unmatched routes and send them to a method which renders an error
	#As in http://techoctave.com/c7/posts/36-rails-3-0-rescue-from-routing-error-solution
