		<description><![CDATA[Update: I&#8217;m using rails 1.2.6 which does not seem to support :through, :source with has_one associations (the docs don&#8217;t show it listed). An alternative is to use &#8220;has_many :categories&#8221; instead and then create helper method &#8220;category&#8221; to return a single category. Say you have a subjects table that will contain two types of classifications and [...]]]></description>

The only difference is that at the end, the printer is added automatically, but it&#8217;s not connected wirelessly. I fixed this by accessing the CUPS server at http://localhost:631/ and then removing the printer, and then adding it again through the CUPS server. Then I could print.

		<description><![CDATA[This is based on findings by metavida. Depending on your association definition in your models, knowing whether to use &#8220;count&#8221;, &#8220;size&#8221;, or &#8220;length&#8221; to retrieve the # of items in a defined association will affect your query speed. To clarify, this regards instances such as @company.workers.count or @company.workers.size, etc. The goal is of course to [...]]]></description>
