title: Where is the best place to put modules that extend your active record models?
body: <p>Just a quick question that strangely I can't find anywhere (maybe I'm wording the question wrong when I ask google)...  I have some shared functionality across a few models, but not shared in any way that I'd want to make an actual class to extend, just small utility methods that I'd like to mix in.  Where is the "best practice" place to put these kinds of modules?  </p>
  
  <p>I can put them in <code>./lib</code>, but that feel wrong for some reason, I'm not sure.  Where's the typical place to put this stuff?</p>
  
  <p><strong>Edit:</strong>  I see why ./lib felt wrong now.  I didn't realize that in rails 3 it no longer autoloads ./lib by default, so I though this had moved elsewhere.  Which I guess it has in the sense that it's now up to you.  Thanks! </p>
