    <p>I'm teaming with a designer for a Rails project, so we had to setup his mac machine with the Rails stack for development. I currently have a OS X Lion Mac, and installed Rails without any issues (with the standard RVM, Homebrew, git, Ruby 1.9.2 and gem set). When I try to follow the same procedure in his Leopard (10.5.8) machine, the result is not as flawless.</p> <p>When I try to run the rails server command, after having installed Rails 3.1 and sqlite-ruby gem, I get the following output:</p> <pre><code> =&gt; Booting WEBrick =&gt; Rails 3.1.1 application starting in development on http://0.0.0.0:3000 =&gt; Call with -d to detach =&gt;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
