title: Make a one-off query to a different database and table
body: <p>I have a rails app with a wordpress blog sellotaped on the side (totally separately at /blog).</p>
  
  <p>The client want's to the latest blog post on the main homepage of the rails app, so I need to do a one-off mysql query to the word-press database. How would I go about doing this in the rails app. The word-press is completely sperate from rails in terms of database.</p>
  
  <p>Cheers.</p>
