rails2.2 和fckeditor不兼容的解决办法

undefined method `relative_url_root' for #<ActionController::CgiRequest:0x23b026>

There is been a Fix for Rails 2.2

in the file app/controllers/fckeditor_controller.rb
look for
uploaded = request.relative_url_root.to_s+"#{UPLOADED}/#{params[:Type]}"

replace it with this
uploaded =
ActionController::Base.relative_url_root.to_s+"#{UPLOADED}/#{params[:Type]}"

similarly in the file lib/fckeditor.rb
replace
js_path = "#{request.relative_url_root}/javascripts"
with
js_path = "#{ActionController::Base.relative_url_root}/javascripts"

reference:
http://github.com/salicio/fckeditor/commit/fcf8fbee8cfad3a3df0df50172...

this worked for me.

修改文件
app/controllers/fckeditor_controller.rb








   def upload_directory_path0
- uploaded = request.relative_url_root.to_s+"#{UPLOADED}/#{params[:Type]}"

+ uploaded = ActionController::Base.relative_url_root.to_s+"#{UPLOADED}/#{params[:Type]}"
     "#{uploaded}#{params[:CurrentFolder]}"
   end
lib/fckeditor.rb








inputs = "<textarea id='#{id}' #{cols} #{rows} name='#{object}[#{field}]'>#{value}</textarea>\n"
       end
      
- js_path = "#{request.relative_url_root}/javascripts"
+ js_path = "#{ActionController::Base.relative_url_root}/javascripts"
       base_path = "#{js_path}/fckeditor/"
       return inputs <<
         javascript_tag("var oFCKeditor = new FCKeditor('#{id}', '#{width}', '#{height}', '#{toolbarSet}');\n" <<
