That's all.

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:

Warning: Kindeditor will load after all the objects loaded.

SimpleForm and Formtastic integration

  <%= 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

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

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', '~> 0.3.19'

运行"bundle"命令：

  bundle

安装Kindeditor，运行下面的代码：

  rails generate rails_kindeditor:install

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_tag :content, :simple_mode => true
  f.input :content, :as => :kindeditor, :input_html => { :simple_mode => true } # simple_form & formtastic  

完毕！

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

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

  gem 'carrierwave-mongoid'
