Ruby on Rails

Paperclip supports multiple files in a single upload anyway. All you need to do is make a form on another parent model (that model should be set to `accepts_nested_attributes_for` the model you have attached your file to), add the multiple => true flag to your file field, and force the name of the file field to conform with this pattern:

:name => 'parent_model_name[attachment_model_name][][attachment_name]

So for User has_many :avatars, accepts_nested_attributes_for :avatars and Avatar has_attached_file :image, the field would be named:

'user[avatars_attributes][][image]'

Upload that nested form and as many Avatar objects as your form field held individual files will be magically created. No drama, no jQuery, no plugins in the browser*.
