So i have a Rails 4.1.x app running on ruby 2.2.x, which only runs on my older laptop because I'm still using rbenv on that. asdf doesnt seem to want to install anything older than ruby 2.4.x

so now I'm on a race with myself to get it upgrades to the last version of rails4 and ruby 2.5.x. I have no tests. this will kill me.

How to skip all filters in controller - Rails

If you need to skip in an specific controller all the filters defined in the ApplicationController, you can do this:

class MyController < ApplicationController if Rails::VERSION::STRING > "2.3" skip_filter *_process_action_callbacks.map(&:filter) else # rails 2.3.x skip_filter filter_chain end end

#rails #rails2 #rails3 #rails4 #ruby on rails #filters #controllers

[Rails4]StrongParameterとFactoryGirlを用いたRspecのスタブ定義

StrongParameterの使用が前提となったRails4では、Rails3でRspecのテスト時にparamsをスタブ定義しつつFactory Girlを使ってデータを生成していると、以下のようなエラーが起きる場合がある。

no implicit conversion of Symbol into String

下記Qiitaに書かれているように、Factory GirlのKeyはHashなのに対し、StrongParameterはKeyがStringであるために発生するっぽい。 http://qiita.com/hisatake/items/ac3a9ea8b681a628e695

なので、この場合paramsのstabにFactory Girlで生成したHashを代入する際に、以下のように定義するとよい。

controller.stub(:params).and_return(ActionController::Parameters.new(FactoryGirl_data))

[Rails4]idパラメータのPOSTの自動型変換

Rails3で idに 001 とか入れてテストしていた。 Rails4からはパラメータ自体は001でコントローラに飛ぶけれど、 Model.find_by_idのときにInteger型に勝手に型変換され 1 で検索が走ってしまうようになった。 Rails3も後期バージョンでは同様の動きかもしれないが、少なくとも自分の環境下ではテストメソッドが失敗していた例が無いので、おそらく仕様変更何だと思う。

Atomic v1.1.14 errors or Xcode/iOS license errors?

Just wanted to share an easy solution to this annoying error with very unconcrete error messages.

If you have recently updated Xcode: Start Xcode and accept the licensing agreements, this completes the Xcode installation and gives you the necessary components to run bundle successfully.

Is this the right answer for you?

It is if you add a new gem to your Gemfile and try to install it using bundle, and get errors such as these:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension. /Users/dlsv/.rvm/rubies/ruby-2.0.0-p353/bin/ruby -r ./siteconf20141024-1494-ur0xga.rb extconf.rb creating Makefile make "DESTDIR=" clean Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.

Then when you re-run it as root, you get this:

An error occurred while installing atomic (1.1.14), and Bundler cannot continue. Make sure that `gem install atomic -v '1.1.14'` succeeds before bundling.

So the reasonable solution is to google the errors and browse various Stack Overflow answers. But even if many answers look simple and convenient to try, it could also be even easier to solve.

Have you recently updated Xcode?

Then you need to start XCode and accept licensing agreements before Xcode proceeds with installing its necessary components.

Components that happen to be necessary for the command-line tools to function properly. Thus also necessary for you in order to successfully run bundle.

Rails 4: モデル

Rails 4: Hello World

Rails 4: JSON、プレーンテキストをレスポンスとして返す

Rails 4: POST リクエストを扱う

Rails 4: Basic 認証

Rails 4: モデル

モデルを生成して、データベースにスキーマを登録しよう。

bin/rails generate model user name:string bin/rake db:migrate

コンソールからデータを登録してみようしてみよう。

bin/rails console user = User.new({name: 'foo'}) user.save user = User.new({name: 'bar'}) user.save

登録したデータを検索してみよう。

User.first.name User.last.name User.find(0) User.find_by(id: 0).name exit

テーブルの定義や実際に登録されたデータを確認してみてよう。デフォルトでは SQLite 3 である。

sqlite3 db/development.sqlite3 .schema users CREATE TABLE "users" ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, "name" varchar(255), "created_at" datetime, "updated_at" datetime); select * from users; .exit

自分だけのために手っ取り早く Basic 認証をかけるには http_basic_authenticate_with を使う。

class HelloController < ApplicationController http_basic_authenticate_with :name => 'foo', :password => 'bar', except: :index def index render plain: 'ok' end def greeting render plain: 'ok' end end

複数のユーザーを想定する場合、before_filter と authenticate_or_request_with_http_basic を組み合わせる。

class HelloController < ApplicationController before_filter :authenticate, except: :index def authenticate authenticate_or_request_with_http_basic('Administration') { |username, password| username == 'foo' && password == 'bar' } end def index render plain: 'ok' end def greeting render plain: 'ok' end end

httpie で確認してみよう。
