view lib/tasks/extract_fixtures.rake @ 599:251b380117ce feature_227

Introduce a new latest_downloads plugin to manage active and shortcut for attachments. Add a table for attachment active/shortcut data. Move existing active-handler code into the new plugin (but still using the "old" active column in the attachments table). Note the files_controller stuff doesn't actually work here.
