I’m attempting to mash together Adva CMS’ Fckeditor and the Fckeditor  
plugin provided by Scott Rutherford.

[http://blog.caronsoftware.com/2008/6/21/fckeditor-plugin-0-5-1-released](http://blog.caronsoftware.com/2008/6/21/fckeditor-plugin-0-5-1-released)

The Scott’s plugin has a controller than handles the Fckeditor file  
upload and browse, but it errors out on the following lines.

def upload\_directory\_path  
uploaded = request.relative\_url\_root.to\_s+“#{UPLOADED}/  
#{params[:Type]}”  
“#{uploaded}#{params[:CurrentFolder]}”  
end

If I remove the request.relative\_url\_root.to\_s it works fine.

def upload\_directory\_path  
uploaded = “#{UPLOADED}/#{params[:Type]}”  
“#{uploaded}#{params[:CurrentFolder]}”  
end

How do I make this go away without editing the plugin code? I found an  
article that says I’m supposed to set it in enviroment.rb but then I  
get errors that constants are not defined/found.
