Rails - Jan 2006 - reading folder structure on server with Rails - possible?

I''m building an extranet which has project folders allocated for each 
client and client project on a webserver.

I''m hoping to be able to read a directory''s content if I give
it a path
like "/clients/[CLIENTNAME]/[PROJECTNAME]" (where /clients/.. would 
reside inside the rails public folder I guess)

preferably recursively so it will read the contents of any 
subdirectories as well.

Is it even possible? How do I go about reading contents of folders? 
Ideally I''d like to be able to add folders and upload files as well,
but
one thing at a time...

Never done it but this should get you started.

Robbie-

	This little snippet will recursively list all files in a directory  
for you. It will also check to make sure they are files and not  
directories being listed.


require ''find''

def recurse_files(dir)
    file_list = ''''
    Find.find(dir) do |file|
       unless test(?d, file)
          file_list << file
       end
     end
    file_list
end

	Now you can do the following in your controller to fill an array  
called @files with all the files in that directory and any directory  
beneath it:

@files = recurse_files("#{RAILS_ROOT}/public/clients")

	Just remember that you must give the full path on the filesystem or  
start with RAILS_ROOT like the example. Hope this helps.

Uhh...  Surely you mean:

def recurse_files(dir)
   Dir.chdir(dir){ Dir[''**/*''].select{|f| File.file? f} }
end


(sorry...  I''m a sucker for one-liners :-)

ok...thanks for the replies, but I''m totally stuck on how to do this 
now.
I want to render out an entire folder structure into xml, and I''ve 
attempted to use the above code to recursively do this, but I keep 
getting an error when the function calls itself

def doSomething
...
@path = "#{RAILS_ROOT}/public/clients/" + dirname + "/" +
@jobnumber +
"/"

@files = ''<struct>''+"\n" +
render_directory(@path,0) + ''</struct>''

end


def render_directory(dir,num)
		if num==0
			str = ''''
		end
		Find.find(dir) do |file|
			if test(?d, file)
				if file != dir
					render_directory(file + "/",1) #dies here!
				end
			else
				str += ''<node label="'' + file + ''"
/>''+"\n"

			end
	     end
	     return str
	end

the error I get is:
 NoMethodError in Project#get_folders

You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.+


Someone out there must have some nice easy code to put a folder 
structure into a nested xml format???

FWIW the xml schema i want looks like
<struct>
<node label="...dir1">
<node label=".../dir1/subdir">
<node label=".../dir1/subdir/file1" />
</node>
<node label="...dir2">
<node label=".../dir2/fileXYZ" />
</node>
</struct>

etc
