chinese_permalink

h1. ChinesePermalink

This plugin adds a capability for ar model to create a seo permalink with your chinese text. It will translate your chinese text to english url based on google translate.

The permalink will be composed of id and the english value translated from chinese text.

For exmpale, title of post is '我是中国人', permalink of post is '1-i-am-a-chinese'

h2. Install

sudo gem install chinese_permalink

h2. Config

As google translator api begins to charge, I decide to use bing translator api, it's free. You have to add a config file to tell chinese_permalink what's your bing app id in config/chinese_permalink.yml

bing:
  app_id: xxx
  language: zh-cht (chinese traditional, default is zh-chs, chinese simplified)

h2. Example

1. Define chinese_permalink to model

class Post < ActiveRecord::Base
  # create permalink by chinese title, default permalink column is "permalink"
  chinese_permalink :title
end

Or

class Post < ActiveRecord::Base
  # create permalink by chinese category and title
  chinese_permalink [:category, :title]
end

Or

class Post < ActiveRecord::Base
  # create permalink by chinese title, store permalink to column "slug_url"
  chinese_permalink :title, :permalink_field => :slug_url
end

2. Generate migration

script/generate chinese_permalink_migration (table name) (permalink column name)

For example:

script/generate chinese_permalink_migration posts

Or

script/generate chinese_permalink_migration posts slug_url

3. Define ar to_param method

class Post < ActiveRecord::Base
  def to_param
    "#{id}-#{permalink}"
  end
end

h2. Advance

You can add before_methods and after_methods to meet your business, for example:

class Post < ActiveRecord::Base
  chinese_permalink :title, :before_methods => :parse_c_sharp

  def parse_c_sharp(permalink)
    permalink.gsub('C#', 'c-sharp')
  end
end

class Post < ActiveRecord::Base
  chinese_permalink :title, :after_methods => :parse_pg

  def parse_pg(permalink)
    permalink.gsub('Procter & Gamble', 'pg')
  end
end
