title: Production Rake Tasks Don't Recognize My Models
body: <p>When I was running Heroku Bamboo, this was never a problem. Now, on Cedar, I get errors whenever I try to access my models from within a rake task on the server. This happens with <code>rake db:seed</code>, a standard rake task, as well as my own custom built tasks that explicitly include :environment. I even do so redundantly:</p>
  
  <pre><code>namespace :db do
    desc "Update db"
    task :new_seed =&gt; :environment do
      require './Scraped_Data/Games/code/column-headers.rb'
      require 'csv'
      require 'net/http'
      require './config/environment.rb'
  
      # code here...
  
    end
  end
  </code></pre>
  
  <p>I can't find any mention of this issue elsewhere, and all of these tasks run perfectly in development. Thanks for any insights, and here is the full error message rake tasks spit out as soon as they encounter a model of mine on Heroku:</p>
  
  <pre><code>rake aborted!
