Signature generate class

lib/signature_generator.rb

module SignatureGenerator
  class Generator
    attr_reader :user_identifier, :consumer_key, :consumer_secret, :api_url, :method

    def initialize(user_identifier, consumer_key, consumer_secret, api_url, method)
      @user_identifier = user_identifier # Encrypted user_id
      @consumer_key    = consumer_key
      @consumer_secret = consumer_secret
      @api_url         = api_url
      @method          = method # GET or POST
    end

    def generate_params
      params = create_params
      signature_base_string = signature_base_string(params)

      signing_key = "#{consumer_secret}&" # or "#{consumer_secret}" different by third party api | consummer_secret + token_secret
      params['oauth_signature'] = sign(signing_key, signature_base_string)

      URI.encode_www_form(params)
    end

    private

    def create_params
      @create_params ||= {
        oauth_version: '1.0',
        oauth_nonce: generate_nonce,
        oauth_timestamp: generate_timestamp,
        oauth_consumer_key: consumer_key,
        user_id: user_identifier, # necessary params
        oauth_signature_method: 'HMAC-SHA1'
      }
    end

    def generate_nonce(size = 32)
      Base64.encode64(OpenSSL::Random.random_bytes(size)).gsub(/W/, '')
    end

    def generate_timestamp
      Time.now.getutc.to_i.to_s
    end

    def signature_base_string(params)
      encoded_params = params.sort.collect { |k, v| url_encode("#{k}=#{v}") }.join('%26')
      "#{method}&#{url_encode(api_url)}&#{encoded_params}"
    end

    def url_encode(url)
      CGI.escape(url)
    end

    def sign(key, base_string)
      digest = OpenSSL::Digest.new('sha1')
      hmac = OpenSSL::HMAC.digest(digest, key, base_string)
      Base64.encode64(hmac).chomp.gsub(/n/, '')
    end
  end
end

Controller

require 'signature_generator'
class MyController < ApplicationController
  include SignatureGenerator

  def show
    user_identifier = current_user.identifier # generate encrypted user_id
    oauth = Generator.new(
      user_identifier,
      ENV['CONSUMER_KEY'],
      ENV['CONSUMER_SECRET'],
      ENV['API_URL'],
      'GET'
    )
    sign = oauth.generate_params
    @iframe_url = "#{ENV['IFRAME_BASE_URL']}?#{sign}"

[Ruby on Rails]Active Job – Sidekiqを使ってのJobの実行 | Developers.IO

はじめに 先日、Ruby on Rails 4.2がリリースされました。このリリースで新たに追加された機能にActive Jobがあります。今回はActive Jobについての簡単な説明と、実際に動かしてみたソースについ […]

ActiveJob テスト方法

by tagged , , , , , | Leave a comment

rspec でジョブのテストはこの gem があります：
[rspec-activejob]
https://github.com/gocardless/rspec-activejob

Rails のソースを見て、 ActiveJob は自分の Test Adapter があります：
https://github.com/rails/rails/blob/master/activejob/lib/active_job/queue_adapters/test_adapter.rb

「enqueued_jobs」というメソッドがあります。これはとてもいいものです！

————————————– マジック開始 ————————————–

describe 'whatever' do
  include ActiveJob::TestHelper

  after do
    clear_enqueued_jobs
  end  

  it 'should email' do
    expect(enqueued_jobs.size).to eq(1)
  end
end

この方法で、ジョブにあるタスクのサイズを確認できます。もっとできるもの、ここを見て、その中に何がありますか：
https://github.com/rails/rails/blob/master/activejob/lib/active_job/queue_adapters/test_adapter.rb#L42

Hashです！では、タスクの値も確認できますね！

p enqueued_jobs.to_s

Will get:
enqueued_jobs:[{:job=>PointJob, :args=>[1], :queue=>"default"}]

job   -> job's class
args  -> job's value
queue -> job's queue name

————————————– マジック完了 ————————————–

ここまで、ジョブの確認は十分でしょうか。

How to add a gender column to user model under devise on rails?

by tagged , , , | Leave a comment

In the application_controller.rb

before_action :configure_devise_permitted_parameters, if: :devise_controller?

protected

def configure_devise_permitted_parameters
  registration_params = [:name, :sex, :description, :email, :password, :password_confirmation]

  if params[:action] == 'update'
    devise_parameter_sanitizer.for(:account_update) { 
      |u| u.permit(registration_params << :current_password)
    }
  elsif params[:action] == 'create'
    devise_parameter_sanitizer.for(:sign_up) { 
      |u| u.permit(registration_params) 
    }
  end
end

Generage a migration to add some custom fields to users table:

class AddNameSexDescriptionToUsers < ActiveRecord::Migration
  def change
    add_column :users, :name, :string
    add_column :users, :sex, :integer, default: 0
    add_column :users, :description, :text
  end
end

Add enum to sex in the user model:

enum sex: [:unknown, :male, :female]

Read data in the devise’s registrations/edit.html.erb view:

<%= f.select :sex, options_for_select(User.sexes.collect { |s| [s[0].humanize, s[0]] }, selected: current_user.sex), {}, class: "form-control" %>

Another way, add a helper method in the user model:

def self.sexes_for_select
  sexes.keys.map{ |x| [x.humanize, x] }
end

Then the view(registrations/edit.html.erb) will be:

<%= f.select :sex, User.sexes_for_select, {}, class: "form-control" %>
