title: Rails 3 - how do I avoid database altogether?
body: <p>I'm trying to use rails 3 without any db backend, but it still insists on requiring 'sqlite3' gem when I try to access a page, and throws an error <code>no such file to load -- sqlite3</code>, even though no code in the application requires sqlite, except I left database.yml with its default setting for sqlite3, since removing the content raised other errors. Any idea how I could use rails without any database and avoid said errors? thanks.</p>
  
  <p>(also, I'm familiar with Sinatra - just prefer rails for this project).</p>
