Rails - Jul 2011 - Can't upload files when WEBrick running in daemon mode.

Hi,
When running my app in development with WEBrick in daemon mode I get the 
following error when trying to upload a file:


  Errno::ENOENT in UploadController#create

No such file or directory - public/data/upload/google

|Rails.root: /home/resource_portal/website|

Application Trace <http://localhost:3000/upload#> | Framework Trace 
<http://localhost:3000/upload#> | Full Trace 
<http://localhost:3000/upload#>

|app/models/upload.rb:29:in `initialize''
app/models/upload.rb:29:in `open''
app/models/upload.rb:29:in `filesave''
app/controllers/upload_controller.rb:16:in `create''
rake-0.8.7/ruby/1.9.1/gems/actionpack-3.0.3/lib/action_controller/metal/implicit_render.rb:4:in
`send_action''
rake-0.8.7/ruby/1.9.1/gems/actionpack-3.0.3/lib/abstract_controller/base.rb:151:in
`process_action''|
...

I do not get this error when not running in daemon mode. I''ve googled a
bit but can''t find a reason. Does anyone have any ideas?

Also the reason I want to run in Daemon mode is because I have to host my app on
a uni virtual machine, and start the server after logging in with ssh. When I
close the ssh connection the server (if not running in background) also seems to
get killed.

Any ideas as to how I may be able to work around this?

Thanks,
Jen.

My guess would be that ''current working directory''
doesn''t mean the
same thing to a daemonized process; how are you specifying the target
directory? Regardless...

Why Webrick? It''s only intended for desktop development work; you
would be better off using e.g. unicorn (my preference) or passenger
in a production environment.

Alternatively, if those aren''t an option, see if you have `screen` on
the
system you''re using (http://www.gnu.org/software/screen/).

I personally use mongrels for my development chops, and passenger in
production environments; I have yet to take the unicorn for a ride. I advise
you to drop WEBrick entirely. Also, be sure to look at this security
considerations <http://guides.rubyonrails.org/security.html#file-uploads>
if
you haven''t yet done so. Security always bears reminding...

Hi,
I solved this by including the absolute path to the directory where the 
uploaded files are placed. Now the code is:

     #takes the upload object and extracts the file.
def filesave
#Calls the .original_filename method on the upload object and stores in 
the variable name
    name = upload.original_filename
     directory = "/home/resource_portal/website/public/data/upload"
   ...

This works with WEBrick, but am now using thin.

Hope this helps anyone else experiencing the same problem.

Cheers,
Jen!
