Hi,
I''m trying to delete a file system (<xml_26548975.xml>)
File.delete("xml_26548975.xml")
But I get this error:
"Permission denied - ./script/../config/../uploads/xml_26548975.xml".
Why?

Cheers,

well, from the error message, it looks like you are not allowed to delete the file due to permissions. i would start there.

What OS are you using for your server?

I''m just uploading a file - copying the content to another file, which
afterwards I want to delete it/unlink it/get lost.
uploaded_file = RAILS_ROOT + "/uploads/xml_" + generate_code +
".xml"
File.open(uploaded_file, "wb") do |f|
f.write(@file.read)
after some time.....File.delete("....").
I''m using XP and WEBrick( I think he''s to blame).
Thanks for your time.

Since if it''s a directory tree or something, you''re not using the correct method (should look at Dir.delete instead). If it is a file, the first thing I would check is if you''re trying to File.delete it while it''s still open. The code below shows you''re using a block scope for the output file, which is good since it takes care of closing the file for you. However, looks like you''re not using the same good pattern for the input file (@file). You can, and should consider it, to avoid bugs like the one that might be haunting you right now (there''s no problem nesting File.open blocks if that''s what hindered you).> File.delete("xml_26548975.xml") > But I get this error: > "Permission denied - ./script/../config/../uploads > /xml_26548975.xml ".Why? > -- > Cheers, > ioana k&a > http://boulangerie.wordpress.com/ > _______________________________________________ > Rails mailing list > Rails@lists.rubyonrails.org > http://lists.rubyonrails.org/mailman/listinfo/rails > > >-- -Alder

That is, I think FileUtils assumes it''s working from RAILS_ROOT whereas File does not. hth, Bill

Does Ruby modify it in some way? (sounds a > bit unlikely...)I don''t know. I''m just going on my recent experience. I''m doing a little app that includes a file upload. After looking back at that code more closely, I''m just more confused. FileUtils.copy seems to need RAILS_ROOT but FileUtils.rm does not. Here''s the file upload code I''m using. @filenametouse = "temp-readin" + nextfile.id.to_s + ".xml" if params[:file_to_upload].instance_of?(Tempfile) FileUtils.copy(params[:file_to_upload].local_path, "#{RAILS_ROOT}/public/#{@filenametouse}") else File.open("#{RAILS_ROOT}/public/#{@filenametouse}","w"){|f| f.write(params[:file_to_upload].read) f.close} end I store the value of @filenametouse in a db record and later retrieve it to delete the file which I do with this code. (emrec.id just identifies the group of files I created in a session) files = Tempfilerec.find(:all, :conditions => ["emrec_id = ?", emrec.id]) files.each {|file| FileUtils.rm "public/#{file.filename}" } I remember being confused when I got the code working but, under deadline pressure, just moved on with a note-to-self to come back later and figure out "why the difference?" Any ideas? Best regards, Bill

My guess is they would be different - RAILS_ROOT for the #rm call, somehing else for the #copy. The CWD is dependent upon your stack setup. For example, with WEBrick it''s often RAILS_DIR throughout the app, while with FastCGI and Lighttpd it''s /public. What''s your setup? -- -Alder
