Using Rails with Paperclip and SWFUpload

Question

I have a basic rails application test with a user model that has a photo field handled with paperclip. I created the views to be able to create/edit an user and the photo uploading is working nicely.

<h1>Editing user</h1>

<% form_for :user, @user, :url => user_path(@user), :html => { :method => "put", :multipart => true } do |f| %>
  <%= f.error_messages %>

  <p>
    <%= f.label :first_name %><br />
    <%= f.text_field :first_name %>
  </p>
  <p>
    <%= f.label :last_name %><br />
    <%= f.text_field :last_name %>
  </p>
  <p>
    <%= f.label :file %><br />
    <%= f.file_field :file %>
  </p>

  <p>
    <%= f.label :photo %><br />
    <%= f.file_field :photo %>
  <p>
    <%= f.submit 'Update' %>
  </p>

<% end %>

<%= link_to 'Show', @user %> |
<%= link_to 'Back', users_path %>

Then, I wanted to integrate SWFUpload in my application. I tried to follow this tutorial and run the test project without any success: the browse button doesn't open a file dialog and an error #2176 is threw which is about the selectFiles() method.

First, the problem is about Flash v.10 that isn't compatible with the old version of SWFUpload (2.1.0) included with the project : selectFiles() is now deprecated. So I tried to upgrade to SWFUpload v. 2.2.0 which now use a button_placeholder_id setting but I can't get any example to work.

So i'm a bit lost about how to use SWFUpload initialization and about and to use it in my form so I can upload and save a photo. Any helps?

You can try using easy-swf-upload plugin

You will just need to insert one helper and maybe adopt css

For passing the photo file field id to SWFUpload, the id of your field is going to be user_photo (from <input type='file' id='user_photo'.../>), so initialize swfupload with

var swfupload = new SWFUpload({button_placeholder_id:'user_photo' ... });

which will replace the file field with a swf uploader.

Bear in mind that by default the file will get uploaded as the 'Filedata' parameter. Technically you could change that to 'user[photo]', but apparently that doesn't work on Linux, so you may have to do some shimmying on the server-side to move that into the right place.
