Here is my setup in my User model

has_attached_file :avatar, PAPERCLIP_OPTIONS.merge(
    :default_url => "//s3.amazonaws.com/bucket-name/media/avatar-placeholder.gif",
    :styles => {
      :"58x58"   => "35x35^",
      :"150x150" => "56x56^",
      :"184x185" => "165x110^",
      :"259x259" => "259x259^"
    },
    :convert_options => {
      :"58x58"   => "-background transparent -auto-orient -gravity center -extent 58x58",
      :"150x150" => "-background transparent -auto-orient -gravity center -extent 150x150",
      :"184x185" => "-background transparent -auto-orient -gravity center -extent 184x185",
      :"259x259" => "-background transparent -auto-orient -gravity center -extent 259x259"
    }
  )

  process_in_background :avatar

Gemfile:

gem 'paperclip', "3.4.2"
gem 'delayed_paperclip'

Nevermind, I fixed it... I am using STI (Single Table Inheritance) in my app... so the Paperclip methods weren't available on the Athlete class

@dennismonsewicz What did you do to fix it? call has_attached_file on all your subclasses?
