傑基爾國際化錯誤

Question

我安裝了國際化的寶石和插件本地化的日期，但是當我所服務的網站，我收到以下錯誤：

Malahovas-MacBook-Pro:test Svetlana$ rake 
Configuration file: /Users/Svetlana/Desktop/test/_config.yml 
      Source: /Users/Svetlana/Desktop/test 
     Destination: /Users/Svetlana/Desktop/test/_site 
     Generating... 
    Liquid Exception: Object must be a Date, DateTime or Time object. "2015-12-01" given. in _includes/footer.html, included in _layouts/post.html 
jekyll 2.5.3 | Error: Object must be a Date, DateTime or Time object. "2015-12-01" given. 

在footer.html我有以下代碼：

<time datetime="{{ page.date | date: "%Y-%m-%d" }}"> 
    {{ page.date | localize: "%d %B %Y" }} 
</time> 

下面是插件i18n_filter.rb代碼：

require 'i18n' 

LOCALE = :ru # set your locale 

# Create folder "_locales" and put some locale file from 
# https://github.com/svenfuchs/rails-i18n/tree/master/rails/locale 
module Jekyll 
    module I18nFilter 
    # Example: 
    # {{ post.date | localize: "%d.%m.%Y" }} 
    # {{ post.date | localize: ":short" }} 
    def localize(input, format=nil) 
     load_translations 
     format = (format =~ /^:(\w+)/) ? $1.to_sym : format 
     I18n.l input, :format => format 
    end 

    def load_translations 
     unless I18n::backend.instance_variable_get(:@translations) 
     I18n.backend.load_translations Dir[File.join(File.dirname(__FILE__), '../_locales/*.yml')] 
     I18n.locale = LOCALE 
     end 
    end 
    end 
end 

這是一個集合的文件。運行建立與--trace後，我得到：

你知道這可怎麼固定？

Answer 1

I18n.localize或I18n.l需要Date，DateTime或Time參數。 page.date實際上應該是DateTime或Time類型，但我假設過濾器沒有加載並因此被Jekyll忽略（我在底部添加了液體過濾器加載）。這裏是一個可能的解決辦法：

嘗試解析調用I18n.localize前輸入字符串：

假設你有一個名爲./locales/文件夾在您的項目目錄中的語言環境文件ru.yml。 i18n.rb置於./_plugins/i18n.rb

require 'date' 
require 'i18n' 

path = File.expand_path("../../locales/ru.yml", __FILE__) 
I18n.load_path = Dir[path] 
I18n.locale = :ru 

module Jekyll 
    module I18nFilter 
    # Example: 
    # {{ post.date | localize: "%d.%m.%Y" }} 
    # {{ post.date | localize: ":short" }} 
    def localize(input, format=nil) 
     format = (format =~ /^:(\w+)/) ? $1.to_sym : format 

     if input.is_a?(String) 
     input = DateTime.parse(input) 
     end 

     I18n.l input, :format => format 
    end 

    def translate(key) 
     I18n.t key 
    end 
    end 
end 

# Add as a filter 
Liquid::Template.register_filter(Jekyll::I18nFilter) 

ru.yml可以是任何有效YAML文件，其中包含的語言環境，例如：

ru: 
    hello: приве́т 

到DateTime的轉化可能會導致一個錯誤，如果是input格式錯誤的字符串，例如空「」或丟失日期所需的東西。最小值應該是這樣的：「2015-01-13」。

作爲Jekyll的替代方案：檢出Nanoc，它似乎更新，更容易擴展。它在Github中使用，我們將它用於我們的所有靜態頁面。localization platform PhraseApp
