Java Bridge Itext Example Anyone?
I MAY be able to derive something out of the present example given here : http://blog.codeinmotion.com/index.php/2006/12/22/pdf-generation-in-ruby-on-rails/ but this deals with filling out forms. Is there a simpler example that just allows you to talk to itext , send it some plain text and get back a pdf and then send that pdf to the user as downloadable / renderable data? -- Posted via

I''m pretty sure this means that I need to specify the encoding somewhere, but I haven''t been able to figure out where or how to do so. Some particulars: I''m running gnuplot through a pipe to generate a plot in .png

Does acts_as_attachment :storage => :db_system work?
I found the post about needing to install acts_as_attachement_1_1_6 if you are not on edge rails. But I am having trouble getting db_system storage to work. As far as I can tell in from the database, things are working, but I don''t see how my model table hooks up with the db_files table so I am having trouble altering the image_tag from the tutorial

Generate JS from RoR - strange delay with send_data
Hi! I need to generate some JS from Ruby. This is no AJAX related stuff so RJS templates are not help to me. Also I want to not mix JS with HTML, so putting JS in .rhtml templates is no go for me. Currently I made some action in controller, prepared JS code and I''m sending it via send_data as ''text/javascript''. In .rhtml templates I use <script> tag with src
