## :memo:

### Step 1: 移動至Gemfile安裝

gem 'friendly_id', '~> 5.4', '>= 5.4.2'
gem 'babosa', '~> 1.0', '>= 1.0.4'

# 移動至Ubuntu使用gem導入至專案
$ bundle

# 移動至Ubuntu,為要加上網址的model,增加slug:inuq
$ rails g migration add_slug_to_story(model) slug:uniq

**移動至/appname/db/migrate再確認**

# /20210503021553_add_slug_to_story.rb
class AddSlugToStory < ActiveRecord::Migration[6.1]
  def change
    add_column :stories, :slug, :string
    add_index :stories, :slug, unique: true
  end
end

# 移動至Ubuntu
$ rails generate friendly_id
$ rails db:migrate

### Step 2: 移動至剛新增:slug欄位的model新增以下程式碼

#路徑:/appname/app/models/story.rb

  # babosa
  def normalize_friendly_id(input)
    input.to_s.to_slug.normalize(transliterations: :russian).to_s
  end
  
  # FriendlyId
  extend FriendlyId
  friendly_id :code_generator, use: :slugged

  private
  # 自定義亂數(方法)   
  def code_generator
      SecureRandom.hex(10)
  end

### Step 3: 移動至剛新增:slug欄位的model的controller修改查詢方式

# 路徑: /appname/app/controllers/stories_controller.rb
# 在原本的查詢方式加上.friendly才能查詢的到!!
def find_story
        @story = current_user.stories.friendly.find(params[:id])
end
