Here's the problem: I am trying to deploy a basic ruby app to Heroku and when I run the following command: heroku run rake db:migrate --trace . I get the above output. Can anyone help me decipher this and maybe get me going in the correct direction to help solve and fix this issue so that I may be able to deploy this app and host it live.

Many thanks in advance.

UPDATE I have included my application.rb and Rakefiles as follows.

application.rb file:

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module Synkline
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de
  end
end



    Rakefile:
    # Add your own tasks in files placed in lib/tasks ending in .rake,
    # for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

    require File.expand_path('../configure/application', __FILE__)

    Rails.application.load_tasks

NameError: undefined local variable or method config' for main:Object
/app/config/application.rb:6:in' 

Look here. Check your app config.
