this article was great !

but i have some question about delete the file

in article when user delete file ALL version will be delete

for example

if i have filename a.txt with version 1,2,3,4,5

when i delete version 5 , version 1,2,3,4 will also delete

so could anyone have solution to delete ONLY SELECTED version

like i choose to delete version 5

it will delete only version 5 not include 1,2,3,4

thanks

Hey David, this is great, thanks for writing it up.

@sandy, yes this works with S3. I have it working there. It will even version your thumbnails for you. Just be sure to have config/amazon_s3.yml set up correctly and change your storage call to :storage => :s3.

Mine is like this:

has_attachment  :storage=>:s3,
                  :path_prefix=>"projects/",
                  :thumbnails => { :thumb => '100x100>' }

The bundled example works fine for me, but breaks when I put it into an existing app running 2.1.1.

Everything works apart from the file updates (calling public_filename returns the correct path, but the corresponding file doesn’t get created). Working on a solution right now…

Hi, looks great. I will be sure to implement this soon. Do you think it would be possible using the S3 feature of attachment_fu. Also, i’ve heard that acts_as_revisionable is a more effective and flexible framework. What are your thoughts?

Cheers

A helpful addenda to this article is that if you are calling the same view to view both the document and the document_version, would be in your model to do this:

def document_id
  id
end

then in your view you can always call

image_tag("/documents/#{@document_id}/v#{version.version/" + version.filename)

and never call @document.id, because your document_versions table will have a different value for id.
