Paperclip with Hobo

Install this plugin alongside paperclip.

It adds two small things:

• Automatically declares the fields for you, so you can just add

   has_attached_file :photo
  

  to your model, and then run the migration generator to add the photo_file_name, photo_content_type, photo_file_size and photo_updated_at fields to the table.

• Declares an input field

   <def tag="input" for="Paperclip::Attachment">
     <%= file_field_tag param_name_for_this, attributes %>
   </def>
  

  (to get this, you need <include src="paperclip" plugin="paperclip_with_hobo" /> in application.dryml)

To get your file upload actually running don't forget to define the form:

<def tag="form" for="User">
  <form merge multipart param="default">
    <error-messages param/>
    <field-list fields="photo" param/>
    <div param="actions">
      <submit label="Save" param/><or-cancel param="cancel"/>
    </div>
  </form>
</def>

<form> must be instructed to create a multipart form and the <field-list> must include the same attachment field which you defined by has_attached_file :photo in your model.

Don't forget to include all the other fields you want to display in the form and last but not least replace User with your actual model.

Important Note

The name of the plugin is important. It doesn't have to be paperclip_with_hobo but it will only work if this plugin loads after paperclip itself. Calling it paperclip_something is a good way to ensure that.
