Rails - Sep 2005 - file_column permission problem

Hi !

My app is hosted on DreamHost, and when I upload files (images 
actually), I want to serve them back to the user.  The application is 
running under FCGI as a specific user.  Since these are static files, 
Apache is trying to serve them, but it can''t see the files because they
have mode 0600.  All middle-level directories have the same access 
permissions.

That''s problem #1.  Problem #2 is that the files might have non ASCII 
characters in their filename.  I''d like to be able to specify a mapping
function that maps the file''s name to something else.  Either a Proc or
a method symbol, just like validate.

#1 is more important to me right now.  The other is a feature request :)

Bye !

Any particular reason File.chmod(0644, filename) wouldn''t do what
you''re
after?

If it doesn''t have to be human-readable, you could base64 encode it
with
Base64.encode64(filename), which would have the advantage that you could
just decode it to get back to the original.

No idea if this is any help whatsoever, just the first things that
popped into my head :-)

Exactly what I was looking for.  Thank, Alex.

I just thought there might be a way to tell the server to inherit file 
permissions.  I''ll just chmod everything I need.

The filenames should not have non ASCII-characters in them, it''s just
a little typo. Just replace the following line in file_column.rb in
the method self.sanitize_filename(filename)

filename.gsub(/[^a-zA-Z0-9\.\-\+_]/,"_")
with
filename.gsub!(/[^a-zA-Z0-9\.\-\+_]/,"_")
(gsub! instead of gsub)

Then everything works as expected. I have sent a diff to Sebastian, it
will surely be corrected in the next version!

Bye,

thanks for the fix, I will certainly include this :) I was travelling
for the past two weeks and got a lot of diffs while I was away so
expect a new version soon...
