redmine集成ckeditor
redmine安装CKEDITOR出错(undefined method 'reply' for class 'IssuesController')
解决办法：

下载redmine_ckeditor(https://github.com/a-ono/redmine_ckeditor)
解压文件，修改文件夹名称为redmine_ckeditor

进入redmine_ckeditor/lib,将issues_controller_patch.rb文件重名为journals_controller_patch.rb
采用文本编辑器打开journals_controller_patch.rb，修改文件内容为：

require_dependency 'journals_controller'

module RedmineCkeditor
  module JournalsControllerPatch
    def self.included(base)
      base.send(:include, InstanceMethods)

      base.class_eval do
        unloadable
        alias_method_chain :new, :ckeditor
      end
    end

    module InstanceMethods
      def new_with_ckeditor
        unless Setting.text_formatting == "CKEditor"
          reply_without_ckeditor
          return
        end

        journal = Journal.find(params[:journal_id]) if params[:journal_id]
        if journal
          user = journal.user
          text = journal.notes
        else
          user = @issue.author
          text = @issue.description
        end
        content = "<p>#{ll(Setting.default_language, :text_user_wrote, user)}</p>"
        content << "<blockquote>#{ActionView::Base.full_sanitizer.sanitize(text)}</blockquote><p/>"

        render(:update) {|page|
          page.<< "CKEDITOR.instances['notes'].setData(#{content.inspect});"
          page << "showAndScrollTo('update', 'notes');"
        }
      end
    end
  end
end

修改redmine_ckeditor/lib/redmine_ckeditor.rb，文件内容为

require 'redmine_ckeditor/journals_controller_patch'
require 'redmine_ckeditor/toolbar_helper'

module RedmineCkeditor
  include ToolbarHelper
  PLUGIN_DIR = File.expand_path(File.dirname(File.dirname(__FILE__)))

  ALLOWED_TAGS = %w[
    a abbr acronym address blockquote b big br caption cite code dd del dfn
    div dt em h1 h2 h3 h4 h5 h6 hr i img ins kbd li ol p pre samp small span
    strike strong sub sup table tbody td tfoot th thead tr tt u ul var
  ]

  ALLOWED_ATTRIBUTES = %w[
    href src width height alt cite datetime title class name xml:lang abbr
    style align valign border cellpadding cellspacing colspan rowspan nowrap
  ]

  DEFAULT_TOOLBAR = [
    %w[Source - Preview - Maximize ShowBlocks - Template - PasteFromWord -
      Undo Redo - Find Replace
    ], '/',
    %w[Bold Italic Underline Strike - Subscript Superscript -
      NumberedList BulletedList - Outdent Indent Blockquote -
      JustifyLeft JustifyCenter JustifyRight JustifyBlock -
      Link Unlink Anchor - Image Table HorizontalRule SpecialChar
    ], '/',
    %w[Styles Format Font FontSize - TextColor BGColor]
  ]

  def self.apply_patch
    JournalsController.send(:include, JournalsControllerPatch)
  end
end
