Railsでguardを使う。(rspec)

# Gemfile:
group :test do
  gem 'rspec-rails'
  gem 'guard-rspec'

  # for Mac
  gem 'rb-fsevent'
  gem 'growl'
end

$ guard init rspec
$ guard start

deviseでログイン後のURLを設定する方法。

deviseではログイン後にはデフォルトでroot_pathに移動するようになってる。それを変えたい。

devise / lib / devise / controllers / helpers.rb

def after_sign_in_path_for(resource_or_scope)
  scope = Devise::Mapping.find_scope!(resource_or_scope)
  home_path = "#{scope}_root_path"
  respond_to?(home_path, true) ? send(home_path) : root_path
end

上記の様にresource(普通はUser)のroot_pathが設定されてればそっちに行くようになってるので下記の様にuser_root_pathに何かを設定すればいい。

# config/routes.rb:
Foo::Application.routes.draw do
  match '/snippets' => 'snippets#index', :as => :user_root
end

ログイン後に/snippetsに行くようになった。

% gem install haml2slim
% ls app/views/emotions 
_form.html.haml edit.html.haml  index.html.haml new.html.haml   show.html.haml
% haml2slim app/views/emotions 
% ls app/views/emotions 
_form.html.haml _form.html.slim edit.html.haml  edit.html.slim  index.html.haml index.html.slim new.html.haml   new.html.slim   show.html.haml  show.html.slim

# app/views/emotions/show.html.slim: 
p#notice= notice
p
  b Body:
  = @emotion.body
p
  b Kind:
  = @emotion.kind
= link_to 'Edit', edit_emotion_path(@emotion)
= link_to 'Back', emotions_path

OMG!

You need devise master to do that.

READMEに書いてあるけど、deviseでhaml or slim(-eオプション)使いたかったら1.1.7じゃ駄目でmaster使えとのこと。1.2rcが正式になったら使えるようになるかも。

RubyでのUUIDのversion 1の使い方。

gem install uuid

>> require 'rubygems'
=> true
>> require 'uuid'
=> true
>> UUID.new
=> MAC: 58:55:ca:f3:26:47  Sequence: 9499
>> UUID.new.generate
=> "bc66c930-22f1-012e-251b-5855caf32647"
>> UUID.new.generate :compact
=> "be64e03022f1012e251b5855caf32647"

:compactはハイフンを取ってくれる。

:compact option omits the hyphens.
