One of the issues that I ran into is that the index is stored in the application root's solr directory. That's usually not a big deal, but if you use capistrano, then you know that you end up with a new application directory with each deploy. So how do you handle that?Well, the proper way is to not rely on the built-in instance of Solr http://feedproxy.google.com/~r/Hackido/~3/YdU_3kRQA4A/capistrano-sunspot-in-rails.htmlnoreply@blogger.com (vince wadhwani)0<p><a href="http://feedads.g.doubleclick.net/~a/LBSKl4ZS_1jMzKarpB2zxN-bN_U/0/da"><img src="http://feedads.g.doubleclick.net/~a/LBSKl4ZS_1jMzKarpB2zxN-bN_U/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/LBSKl4ZS_1jMzKarpB2zxN-bN_U/1/da"><img src="http://feedads.g.doubleclick.net/~a/LBSKl4ZS_1jMzKarpB2zxN-bN_U/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/Hackido/~4/YdU_3kRQA4A" height="1" width="1"/>http://www.hackido.com/2010/03/capistrano-sunspot-in-rails.htmltag:blogger.com,1999:blog-689869310107675036.post-5842432732765374250Tue, 16 Feb 2010 02:42:00 +00002010-02-15T22:55:07.883-05:00cyanogenandroidA while back I followed this great video tutorial from Android and Me to get root access on my Nexus One.

If you just want to validate something in your form it's as easy as specifying the validation in your model and letting Rails take care of the rest. But what if you want to validate a form_tag? Generally, we use form_tag when there's no model associated with our form. Without the model we can't use Activerecord validations!
