activeupload

OverviewActiveUpload is Rails plugin that allows you to quickly and easily accept uploaded files and attach them to any model in your application. It uses a slightly modified version SWFUpload to create an elegant user experience, while at the same time being simple and flexible for the developer. ... [More] ActiveUpload also works with ActiveScaffold. See the ActiveScaffold section below for details. InstallationTo install and and use the plugin, perform the following steps. First install the plugin: ./script/plugin install http://activeupload.googlecode.com/svn/trunk/activeupload/Second, generate the migration, model and controller ./script/generate activeuploadThird, add the following lines to any model you wish to attach files to: has_many :attachments, :as => :attachable def attachment_id=(attachment_id) unless attachment_id.blank? attachments.clear attachment_ids = attachment_id.split(",") attachment_ids.each do |a_id| unless a_id.blank? attachment = Attachment.find(a_id) attachments << attachment end end end end def attachment_id result = "" if attachments attachments.each do |attachment| result << ",#{attachment.id}" end end result endFourth, add the form helpers to your new and edit views: Attachments <%= f.attachments_field :attachment_id, { :add => "true", :edit =>"true", :filesize => 30720, :filetypes => [ "*.gif", "*.jpg", "*.png" ] } %> Fifth, add the view helper to your show view: Attachments <%= view_attachments_field(@bench, {}) %> Sixth and lastly, add the javascript and stylesheets to your layout: <%= javascript_include_tag :defaults %> <%= stylesheet_link_tag 'swfupload_theme' %> <%= javascript_include_tag "swfupload_callbacks.js" %> <%= javascript_include_tag "SWFUpload.js" %>ActiveScaffoldActiveUpload works well with ActiveScaffold. To get ActiveScaffold to render the correct upload forms you must create a partial form override. Luckily, ActiveUpload comes with one. In the plugin's public directory ($PROJECT/vendor/plugins/activeupload/public/) you will find a file named attachment_id_form_column.rhtml. Copy that file to your models views directory ($PROJECT/app/views/$MODEL/). cp vendor/plugins/activeupload/public/_attachment_id_form_column.rhtml app/views/modelSince attachment_id is a virtual column, you will need to tell ActiveScaffold to use it, you can do that by adding the following code to your model's controller: active_scaffold :model_name do |config| config.create.columns = [:column1, :column2, :attachment_id] config.update.columns = [:column1, :column2, :attachment_id] endFinally, add the following code to your attachments_controller: active_scaffold [Less]
