【緩募】Rubyリファレンス・マニュアル＝るりまで不足中のサンプルコード8,000件を一緒に作りませんか？ - Tbpgr Blog
3行で説明すると Rubyは他言語に比べてリファレンスのサンプルコードが不足気味という意見があった 私が「やりましょう」と言った hanachin_ さんが調査スクリプトを作った結果ざっくり8,000件不足していることがわかった より詳しい話 もうちょっと詳しい流れはこのIssueにあります。 github.com 現状すでに多数のIssue, Pull Requestに話がまたがってしまっているので雑にまとめると サンプルコードをどのように書くかのガイドラインを私が作成済 サンプルコードはあるがそのままでは実行できないものがある hanachin_ さんが調査用の自作ツール＋手作業で多数修正。完成率は不明 サンプルコードがないもの hanachin_ さん作成した調査ツールにより、調査開始時点で約8,000件あることがわかっている Rubyのrdocにサンプルがあるものはそのまま移植した
DHH流のルーティングで得られるメリットと、取り入れる上でのポイント - KitchHike Tech Blog
はじめに こんにちは。KitchHikeエンジニアの小川です。KitchHikeでは主にサーバーサイドを担当しています。 少し前のものですが、「DHHはどのようにRailsのコントローラを書くのか (原文)」というすばらしい記事があります。Railsのコントローラ分割の(DHH流)ベストプラクティスについて解説した記事なのですが、私はこの記事に大変感銘を受け、KitchHikeのルーティング定義にもこのプラクティスを取り入れるようになりました。 本日はこのDHH流ルーティングを取り入れることで得られるメリット、実際の routes.rb でのルーティング定義のしかたについて紹介したいと思います。 DHH流ルーティングとは？何がうれしいの？ 詳しくは元記事を是非とも読んで下さい・・・なのですが、かいつまむと、ここで示されているのはたったひとつの単純明快なルールです。 コントローラはデフォルト

(Railsで)プロフィール更新みたいなやつの注意点 - けんちゃんくんさんのWeb日記
前職と現職で2アウト案件。 Railsに限らないけど、ログインユーザの情報を変更するときは current_user みたいな変数を変更するんじゃなくて、DBを引き直して更新しましょうって話。 ダメな例 class ProfileController def update if current_user.update(profile_params) redirect_to :root else render :edit end end end 良い例 class ProfileController def update @user = User.find(current_user) if @user.update(profile_params) redirect_to :root else render :edit end end end なんでだめなの？ バリデーションエラーが起きた時に

Running concurrent workflows in Ruby
Have you ever struggled with a chain of rake tasks that needed to be run periodically and their runtime was giving you a headache? Did you ask yourself how to save time by boosting execution along with readability for huge chunks of jobs? These questions are very common when it comes to applications with hefty amount of background processing jobs. It is my own experience that inspired me to write
Responsibly Use Peek to Inspect Rails
I love developing applications with the peek gem. It's designed for development or staging environments; there are a few tricks if you don't want it on production or test environments. This gem puts a little bar on your pages which gives you all sorts of helpful information about the request you just made. As you can see there is information about the branch you're on, performance metrics, databas

The Ruby word is traditionally bound to the microservice approach by the glorious minimal web framework Sinatra. There are many good ruby micro frameworks but Grape coupled with Swagger UI via the g
Effective TDD With Ruby: Tmux Setup · Luca Guidi
Do you find Test Driven Development (TDD) good in theory but hard to practice? Do you think it requires too much discipline and you don’t have time? Or, are you just struggling to get your workflow streamlined? Fighting to glue your tools together? Well, you can improve a lot, by borrowing some tricks from me. I’ve practiced TDD with Ruby for many years now, and built an entire web framework only
The Safe Navigation Operator (&.) in Ruby - Georgi Mitrev
The most interesting addition to Ruby 2.3.0 is the Safe Navigation Operator(&.). A similar operator has been present in C# and Groovy for a long time with a slightly different syntax - ?.. So what does it do? TLDR It is used for avoiding NoMethodError exceptions when calling methods on objects that may be nil. account = nil account.number # => NoMethodError (undefined method `number' for nil:NilCl
Five Active Record Features You Should Be Using
Active Record is responsible for communicating with the persistence layer by default in Ruby on Rails applications. Using Active Record effectively and efficiently can greatly improve an application’s code. In Ruby on Rails 4.0, some material changes have been made to Active Record. Understanding these changes, and how they are best utilized is important for any Rails developer. To help explain th
How to write a Cucumber test for Google Maps | Mix & Go
The other day I’ve stumbled upon an interesting challenge. I had to write a feature test for a pin showing up on Google Maps. So basically the feature was supposed to check that when a user visits a particular page, he would be able to see a pin on a Google map. Initially I thought this should be pretty easy to implement, I would just do a find using the right DOM selector and that’s that. So let’

Writing Ruby extensions in Go – an in depth review
For a very long time the only way to extend Ruby with native estensions has been using C. I don’t have the numbers with me, but I guess C is not the first choice for Ruby programmers when they have to pick up a secondary/complentary language. So I started investigating the possibility of writing them in other languages, taking advantage of the favorable moment: in the past 3-4 years we had an expl
Full Stack Fest 2015: Request and Response, by Aaron Patterson
A talk from Full Stack Fest 2015 (http://fullstackfest.com/) What goes in to a request and response in a Rails application? Where does the application get its data, and how does that data get to the client when you are done? In this talk we’ll look at the request and response lifecycle in Rails. We’ll start with how a request and response are serviced today, then move on to more exciting topics l
