rails2.2 和fckeditor不兼容的解决办法。

在更新了Rails2.2后发现和fckeditor出现了兼容性问题。搜了一下找到解决办法如下。

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"

this worked for me.
