    <p><strong>Should it use apache or nginx?</strong> Nginx seems to be the preferred route here, unless you need specific Apache features. If you're using Passenger, both Apache and Nginx are supported. More on Passenger <a href="http://www.modrails.com/" rel="noreferrer">here</a>.</p> <p><strong>Ruby Enterprise Edition or just normal Ruby?</strong> I'm pretty sure REE is only available for Ruby 1.8, which isn't really the preferred version for Rails 3 anymore. Rails 3 had some problems with 1.8, but they might have fixed them by now. Generally, though, Ruby 1.9.2 runs Rails 3 well.</p> <p><strong>Ideal linux distro?</strong> This really doesn't matter. If you're not sure, Ubuntu is a good choice as there's a lot of knowledge out there, and it's pretty easy to use. Slicehost has a bunch of great articles on getting started with a VPS, and a lot of them focus specifically on Ubuntu: <a href="http://articles.slicehost.com/" rel="noreferrer">http://articles.slicehost.com/</a>.</p> <p><strong>MySQL, PostgreSQL or something else?</strong> This is definitely subjective. MySQL is definitely the most common out there, and if you're really unsure, it's a good starting point. However, people often argue that PostgreSQL is cleaner and easier to use that MySQL. If you're just starting, I would recommend MySQL just because of the amount of information out there already.</p> <p><strong>How should the directories be laid out (where to put your rails sites or anything else)?</strong> You can put your rails project anywhere you like, so I like to just put it in my home directory. Just make sure that your web server has access to your static assets.</p> <p><strong>Deployment options?</strong> Capistrano is popular. You just commit your changes and <code>cap deploy</code>, and you'll be up and running.</p> <p><strong>Anything else?</strong> If this all seems overwhelming, look into a simpler solution like <a href="http://heroku.com" rel="noreferrer" title="Heroku">Heroku</a>. They set everything up for you, and, while you loose some flexibility, you won't have to worry about any of this. Their pricing isn't too bad, and they offer a free option.</p>

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).
