Kindeditor for Ruby on Rails

Kindeditor is a WYSIWYG javascript editor, visit http://www.kindsoft.net for details.
rails_kindeditor will helps your rails app integrate with kindeditor, includes images and files uploading.

Installation and usage

Add this to your Gemfile

  gem 'rails_kindeditor'

Run "bundle" command.

  bundle

Run install generator:

  rails generate rails_kindeditor:install

notice: rails_kindeditor needs applications.js in your project.

Rails4 in production mode

In Rails 4.0, precompiling assets no longer automatically copies non-JS/CSS assets from vendor/assets and lib/assets. see https://github.com/rails/rails/pull/7968
In Rails 4.0's production mode, please run 'rake kindeditor:assets', this method just copy kindeditor into public folder.

  rake kindeditor:assets

Usage:

  1. <%= kindeditor_tag :content, 'default content value' %>
     # or <%= kindeditor_tag :content, 'default content value', :width => 800, :height => 300 %>
     # or <%= kindeditor_tag :content, 'default content value', :allowFileManager => false %>

  2. <%= form_for @article do |f| %>
       ...
       <%= f.kindeditor :content %>
       # or <%= f.kindeditor :content, :width => 800, :height => 300 %>
       # or <%= f.kindeditor :content, :allowFileManager => false %>
       ...
     <% end %>

You can use kindeditor's initial parameters as usual, please visit http://www.kindsoft.net/docs/option.html for details.

additionally, rails_kindeditor provides one "simple_mode" parameter for render simple mode quickly.

  kindeditor_tag :content, 'default content value', :simple_mode => true
  f.kindeditor :content, :simple_mode => true
  f.input :content, :as => :kindeditor, :input_html => { :simple_mode => true } # simple_form & formtastic

That's all.

Work with turbolinks

rails_kindeditor will not load the scripts under the turbolinks, there's two way to solve this problem:

1.use "'data-no-turbolink' => true" when we need to load kindeditor，this will shut down the turbolinks in this page

  <%= link_to 'Edit', edit_article_path(article), 'data-no-turbolink' => true %>

2.load kindeditor manually, but you should specify the parameters again, include the textarea's id.

  # coffeescript code
  $(document).on 'page:load', ->
    if $('#article_content').length > 0
      KindEditor.create '#article_content', "width":"100%", "height":300, "allowFileManager":true, "uploadJson":"/kindeditor/upload", "fileManagerJson":"/kindeditor/filemanager"

simple mode

  # coffeescript code
  $(document).on 'page:load', ->
    if $('#article_content').length > 0
      KindEditor.create '#article_content',
                      "width":"100%",
                      "height":300,
                      "allowFileManager":true,
                      "uploadJson":"/kindeditor/upload",
                      "fileManagerJson":"/kindeditor/filemanager",
                      "items":["fontname","fontsize","|","forecolor","hilitecolor","bold","italic","underline","removeformat","|","justifyleft","justifycenter","justifyright","insertorderedlist","insertunorderedlist","|","emoticons","image","link"]

When you need to specify the owner_id：

f.kindeditor :content, owner_id: @article.id, data: {upload: kindeditor_upload_json_path(owner_id: @article.id), filemanager: kindeditor_file_manager_json_path}

  # coffeescript code
  $(document).on 'page:load', ->
    if $('#article_content').length > 0
      KindEditor.create '#article_content',
                        "width" : "100%",
                        "height" : 300,
                        "allowFileManager" : true,
                        "uploadJson" : $('#article_content').data('upload'),
                        "fileManagerJson" : $('#article_content').data('filemanager')

Include javascript files at bottom ? Not in the head tag ? How can I load kindeditor correctly ?

For some reasons, you includes javascript files at bottom in your template, rails_kindeditor provides a options for lazyload:

  <%= f.kindeditor :content, :window_onload => true %>

Warning: Kindeditor will load after all the objects loaded.

SimpleForm and Formtastic integration

simple_form:

  <%= form.input :content, :as => :kindeditor %>
  # or
  <%= form.input :content, :as => :kindeditor, :label => false, :input_html => { :width => 800, :height => 300 } %>

formtastic:

  <%= form.input :content, :as => :kindeditor %>
  # or
  <%= form.input :content, :as => :kindeditor, :input_html => { :height => 300 } %>

How to get kindeditor's content

  <%= form_for @article do |f| %>
    <%= f.kindeditor :content, :editor_id => 'my_editor' %>
  <% end %>

You can get content like this:

  // Javascript code
  my_editor.html();

Upload options configuration

When you run "rails generate rails_kindeditor:install", installer will copy configuration files in config/initializers folder.
You can customize some option for uploading.

  # Specify the subfolders in public directory.
  # You can customize it , eg: config.upload_dir = 'this/is/my/folder'
  config.upload_dir = 'uploads'

  # Allowed file types for upload.
  config.upload_image_ext = %w[gif jpg jpeg png bmp]
  config.upload_flash_ext = %w[swf flv]
  config.upload_media_ext = %w[swf flv mp3 wav wma wmv mid avi mpg asf rm rmvb]
  config.upload_file_ext = %w[doc docx xls xlsx ppt htm html txt zip rar gz bz2]

  # Porcess upload image size, need mini_magick
  #     before    => after
  # eg: 1600x1600 => 800x800
  #     1600x800  => 800x400
  #     400x400   => 400x400 # No Change
  # config.image_resize_to_limit = [800, 800]

Save upload file information into database(optional)

rails_kindeditor can save upload file information into database.

Just run migration generate, there are two ORM options for you: 1.active_record 2.mongoid, default is active_record.

  rails generate rails_kindeditor:migration
  or
  rails generate rails_kindeditor:migration -o mongoid

The generator will copy model and migration to your application. When you are done, remember run rake db:migrate:

  rake db:migrate

Delete uploaded files automatically (only for active_record)

You can specify the owner for uploaded files, when the owner was destroying, all the uploaded files(belongs to the owner) will be destroyed automatically.

####1. specify the owner_id for kindeditor

   <%= form_for @article do |f| %>
     ...
     <%= f.kindeditor :content, :owner_id => @article.id  %>
     ...
   <% end %>

Warnning: the @article must be created before this scene, the @article.id should not be empty.

####2. add has_many_kindeditor_assets in your own model

  class Article < ActiveRecord::Base
    has_many_kindeditor_assets :attachments, :dependent => :destroy
    # has_many_kindeditor_assets :attachments, :dependent => :nullify
    # has_many_kindeditor_assets :your_name, :dependent => :destroy
  end

####3. relationship

  article = Article.first
  article.attachments # => the article's assets uploaded by kindeditor
  asset = article.attachments.first
  asset.owner # => aritcle

If you're using mongoid, please add 'gem "carrierwave-mongoid"' in your Gemfile

  gem 'carrierwave-mongoid'

Kindeditor for Ruby on Rails 中文文档

Kindeditor是国产的所见即所得javascript富文本编辑器, 访问 http://www.kindsoft.net 获取更多信息.
rails_kindeditor可以帮助你的rails程序集成kindeditor,包括了图片和附件上传功能，文件按照类型、日期进行存储。

安装及使用

将下面代码加入Gemfile：

  gem 'rails_kindeditor'

运行"bundle"命令：

  bundle

安装Kindeditor，运行下面的代码：

  rails generate rails_kindeditor:install

注意： 在你的工程中需要有application.js文件。

Rails4 in production mode

从Rails 4.0开始, precompiling assets不再自动从vendor/assets和lib/assets拷贝非JS/CSS文件. 参见 https://github.com/rails/rails/pull/7968
如果要使用Rails 4.0的生产模式，请运行'rake kindeditor:assets', 此方法可将kindeditor自动拷贝到你的public/assets目录.

  rake kindeditor:assets

使用方法:

  1. <%= kindeditor_tag :content, 'default content value' %>
     # or <%= kindeditor_tag :content, 'default content value', :width => 800, :height => 300 %>
     # or <%= kindeditor_tag :content, 'default content value', :allowFileManager => false %>

  2. <%= form_for @article do |f| -%>
       ...
       <%= f.kindeditor :content %>
       # or <%= f.kindeditor :content, :width => 800, :height => 300 %>
       # or <%= f.kindeditor :content, :allowFileManager => false %>
       ...
     <% end -%>

你可以像往常那样使用kindeditor自身的初始化参数，请访问 http://www.kindsoft.net/docs/option.html 查看更多参数。

另外，rails_kindeditor还额外提供一个"simple_mode"参数，以便快捷使用简单模式的kindeditor。

  kindeditor_tag :content, 'default content value', :simple_mode => true
  f.kindeditor :content, :simple_mode => true
  f.input :content, :as => :kindeditor, :input_html => { :simple_mode => true } # simple_form & formtastic  

完毕！

如何在turbolinks下使用

rails_kindeditor在turbolinks下不会正常加载，只有当页面刷新时才正常。turbolinks的机制就是这样的，页面根本没刷新，这和pjax是一样的，所以kindeditor没加载很正常。

有两个办法可以解决：

1.在需要加载kindeditor的链接加入 'data-no-turbolink' => true ，此时相当在这个页面于关闭turbolinks。

  <%= link_to 'Edit', edit_article_path(article), 'data-no-turbolink' => true %>

2.在turbolinks载入完毕后手动加载kindeditor，不过所有参数都要设置，而且需要知道并设定textarea的id。

  # coffeescript code
  $(document).on 'page:load', ->
    if $('#article_content').length > 0
      KindEditor.create '#article_content', "width":"100%", "height":300, "allowFileManager":true, "uploadJson":"/kindeditor/upload", "fileManagerJson":"/kindeditor/filemanager"

simple模式也需要手动设定

  # coffeescript code
  $(document).on 'page:load', ->
    if $('#article_content').length > 0
      KindEditor.create '#article_content',
                      "width":"100%",
                      "height":300,
                      "allowFileManager":true,
                      "uploadJson":"/kindeditor/upload",
                      "fileManagerJson":"/kindeditor/filemanager",
                      "items":["fontname","fontsize","|","forecolor","hilitecolor","bold","italic","underline","removeformat","|","justifyleft","justifycenter","justifyright","insertorderedlist","insertunorderedlist","|","emoticons","image","link"]

需要指定owner_id的方法：

f.kindeditor :content, owner_id: @article.id, data: {upload: kindeditor_upload_json_path(owner_id: @article.id), filemanager: kindeditor_file_manager_json_path}

  # coffeescript code
  $(document).on 'page:load', ->
    if $('#article_content').length > 0
      KindEditor.create '#article_content',
                        "width" : "100%",
                        "height" : 300,
                        "allowFileManager" : true,
                        "uploadJson" : $('#article_content').data('upload'),
                        "fileManagerJson" : $('#article_content').data('filemanager')

把javascript放在模板最下方，不放在head里面，如何正确加载kindeditor？

有时候，为了加快页面载入速度，也许你会把javascript引用放在template的底部，rails_kindeditor提供了一个参数可以确保正常加载：

  <%= f.kindeditor :content, :window_onload => true %>

警告：Kindeditor会在页面所有的内容加载完毕后才进行加载，所以需谨慎使用

SimpleForm与Formtastic集成：

simple_form:

  <%= form.input :content, :as => :kindeditor, :label => false, :input_html => { :width => 800, :height => 300 } %>

formtastic:

  <%= form.input :content, :as => :kindeditor %>
  <%= form.input :content, :as => :kindeditor, :input_html => { :height => 300 } %>

如何获取kindeditor的内容

  <%= form_for @article do |f| %>
    <%= f.kindeditor :content, :editor_id => 'my_editor' %>
  <% end %>

可通过下面的Javascript代码获取内容:

  // Javascript code
  my_editor.html();

上传图片及文件配置

当你运行"rails generate rails_kindeditor:install"的时候，安装器会将配置文件拷贝到config/initializers文件夹。
你可以配置以下上传选项：

  # 指定上传目录，目录可以指定多级，都存储在public目录下.
  # You can customize it , eg: config.upload_dir = 'this/is/my/folder'
  config.upload_dir = 'uploads'

  # 指定允许上传的文件类型.
  config.upload_image_ext = %w[gif jpg jpeg png bmp]
  config.upload_flash_ext = %w[swf flv]
  config.upload_media_ext = %w[swf flv mp3 wav wma wmv mid avi mpg asf rm rmvb]
  config.upload_file_ext = %w[doc docx xls xlsx ppt htm html txt zip rar gz bz2]

  # 处理上传文件，需要mini_magick
  #     处理以前      => 处理以后
  # eg: 1600x1600 => 800x800
  #     1600x800  => 800x400
  #     400x400   => 400x400 # 图片小于该限制尺寸则不作处理
  # config.image_resize_to_limit = [800, 800]

将上传文件信息记录入数据库（可选）

rails_kindeditor 可以将上传文件信息记录入数据库，以便扩展应用.

运行下面的代码，有两项选项：1.active_record 2.mongoid，默认是active_record。

  rails generate rails_kindeditor:migration
  or
  rails generate rails_kindeditor:migration -o mongoid

运行下面的代码：

  rake db:migrate

自动删除上传的文件(仅在active_record下工作)

你可以为上传的文件指定归属，比如一名用户，或者一篇文章，当用户或者文章被删除时，所有属于该用户或者该文章的上传文件将会被自动删除。

####1. 为kindeditor指定owner_id

   <%= form_for @article do |f| %>
     ...
     <%= f.kindeditor :content, :owner_id => @article.id  %>
     ...
   <% end %>

警告: @article应该事先被创建，@article.id不应该是空的。

####2. 在你自己的模型里加入has_many_kindeditor_assets

  class Article < ActiveRecord::Base
    has_many_kindeditor_assets :attachments, :dependent => :destroy
    # has_many_kindeditor_assets :attachments, :dependent => :nullify
    # has_many_kindeditor_assets :your_name, :dependent => :destroy
  end

####3. 相互关系

  article = Article.first
  article.attachments # => the article's assets uploaded by kindeditor
  asset = article.attachments.first
  asset.owner # => aritcle

如果你使用的是mongoid, 请在你的Gemfile里加入'gem "carrierwave-mongoid"'

  gem 'carrierwave-mongoid'
