Hi, i just found the acts_as_attachment plugin for image upload, seems sogood but i cant find any docs about it, if someone here using it can give some references or working examples about the plugin that will be excellent. So what you wanna rails today? -- Posted via http://www.ruby-forum.com/.
I once took a closer look at Mephisto CMS/Blog engine, from the same author (Rick Olson), which I think was using that plugin On 5/31/06, Nhila Dasgota <dasgot_k@gmail.com> wrote:> > Hi, i just found the acts_as_attachment plugin for image upload, seems > sogood but i cant find any docs about it, if someone here using it can > give some references or working examples about the plugin that will be > excellent. > > So what you wanna rails today? > > -- > Posted via http://www.ruby-forum.com/. > _______________________________________________ > Rails mailing list > Rails@lists.rubyonrails.org > http://lists.rubyonrails.org/mailman/listinfo/rails >-- Roberto Saccon -------------- next part -------------- An HTML attachment was scrubbed...

"local_path" and i.local_path and File.exists?(i.local_path) FileUtils.mv(i.local_path,imagedir+i.original_filename) elsif i.respond_to?(:read) File.open(imagedir+i.original_filename, "wb") {|f| f.write(i.read)} cheers -- Posted via http://www.ruby-forum.com/.

I know it seems like NIH since there''s the file_column plugin, but I originally wrote acts_as_attachments so I could store attachments in the DB for Mephisto (user avatars, templates, etc). As I started using it, it became apparent that larger files would need to be stored in the file system. So with the help of some other folks, I wrote the file system portion. Your problem is that you passed a TempFile to Attachment.new(), which expects a hash. The Attachment model has a handy uploaded_data method that handles the file upload. You just structure your form like this: <% form_for :attachment do |f| -%> <%= f.file_field :uploaded_data %> <% end -> Then in the controller: @attachment = Attachment.new(params[:attachment]) @attachment.save ... This will automatically call @attachment.uploaded_data params[:attachment][:uploaded_data], which sets the content type, filename, and attachment data. If you''re doing this from the command line to pre-populate attachments, you can just do this: @attachment.new(:attachment_data => IO.read(''path/to/file''), :filename => ''foo.gif'', :content_type => ''image/gif'') I don''t know, maybe you can even do File.open(''foo.gif'') do |f| @attachment.new(:uploaded_data => f) end I hope this helps a bit. -- Rick Olson http://techno-weenie.net -- Rick Olson http://techno-weenie.net
