Rails - Mar 2006 - Questions about file_column plugin

Hi!

I''ve got 2 models - let''s call them User and Image. User
has_many
images. (Thanks to Mark Reginal James :) ) I have a single form where i 
can create a user and add to him any number of images, which are 
uploaded using file_column plugin.


Now 3 questions:

1. How to change the default path where file_column plugin saves images, 
so it will save them in a directory, which name is not image id, but 
user id to which the image belongs to?

2. When user objects fails validation, but images were ok, i''d like to 
display thumbnails of temporarly uploaded files by file_column, so that 
user can see that they were acutally correctly uploaded. What is the 
name of the variable in file_column that keeps path to the images and 
how to access it from the view?

3. What is the best way to automatically delete files in the "tmp" 
folder? It gets huge very quickly. I don''t think that scheduling 
deleting of these files is good solution, because user could be filling 
his form while tmp folder is being deleted. Maybe i could somehow add a 
callback that it will delete temporary image if it was succesfully 
saved? But how? :)

That''s all. Thanks in advance.

It turned out that i wasn''t using latest trunk version of file_column 
plugin. New version solved above mentioned problems, but introduced a 
new one.

If i specify dynamic default storage dir for images like this:

  file_column :name,
              :store_dir => :dynamic_dir

  def dynamic_dir
    File.join("images","properties",self.property.id.to_s)
  end

how can i later access images using url_for_file_column method? It seems 
to be ignoring :store_dir option.

you could schedule deletion of files that were 24hrs+ old in unix with something
like this:

find /full/img/path/tmp/ -type d -mtime -1 -exec rm -r {};

so, find in the path things of type ''directory'' 1 day old (at
least) then rm -r each directory.
(you should probably test that :) )

not sure about the other bits...
