Remote Heroku application crashes; local is fine

I have a rails app that works locally (tested with bundle exec), but crashed on Heroku (Cedar stack). The configuration locally is identical to the remote, (both are using Postgres). The crash is actually rather perplexing to me, because the stack trace makes appears to be occurring within the Rails/Thin environment. The deprecation warning is equally perplexing, as there is nothing in my vendor/plugins directory!

Starting process with command `bundle exec thin start -R config.ru -e $RAILS_ENV -p 38427`
DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/ and config/initializers/myplugin.rb. See the release notes for more on this: http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released. (called from <top (required)> at /app/config/environment.rb:5)

Process exited with status 1
State changed from starting to crashed

I have already run rake db:reset and rake db:migrate just to be sure that its not an issue with the database system.

Your model should look like this.

class Transcript < ActiveRecord::Base
  attr_accessible :grade, :hours

  belongs_to :student, class_name: 'User', dependent: :destroy
  belongs_to :course
end

What happened was that you didn't define destroy as a string or a hash. Hence why you got...

`destroy': wrong number of arguments (0 for 1) (ArgumentError)
