Hi everyone,

I have a bunch of pdf files stored in a database (blob field) and now i  
am asked to “transform” them into file system.  
Is there any way to do that;  
I tried something along the lines of  
FileObject.find(:all).each do |fo|  
f = File.new("#{fo.name}" + “.pdf”, “w”)  
f \<\< fo.file\_field  
f.close  
f = nil  
end

The files get created but when i try to open the newly pdf file created  
they are blank (just blank pages in each doc)

Any ideas on this; any input is appreciated.
