    <p>Current versions of Rails are designed to work (for development) without needing an AMP -style stack, by using SQLite and a small Ruby Web server, so if you will only be doing Rails development you don't need to set up a stack - you can just type "rails" and it will work.</p> <p><strong>BUT</strong> the versions of RubyGems and Rails shipped with Leopard are now outdated, though, so you'll need to upgrade these before you go too far. There's an article that I wrote on setting up a Mac for development <a href="http://www.stuartellis.eu/articles/mac-setup/" rel="nofollow noreferrer">here</a>, but the minimum commands go like this:</p> <ol> <li>sudo gem install rubygems-update</li> <li>sudo update_rubygems</li> <li>sudo update_rubygems (yep, twice)</li> <li>sudo gem update --system</li> </ol> <p>These get RubyGems up to the current release, so that you can upgrade Rails safely. To do that, type:</p> <pre><code>gem update rails </code></pre> <p>The last command doesn't have sudo, because if you omit it, current versions of RubyGems will install a clean copy of the gems into your home directory, leaving the system versions untouched.</p> <p>Finally, amend the .profile file in your home directory, so that the line with PATH in it says:</p> <pre><code>export PATH=$HOME/.gem/ruby/1.8/bin:$PATH </code></pre> <p>Close up any terminal windows for this to take effect. The utilities provided by the gem packages in your home directory will now have precedence over the system versions.</p> <p>This means that you can type "rails" and the latest version will run, but you haven't messed with any of the software provided by Apple (apart from the system copy of RubyGems).</p> <p>To upgrade your private copy of Rails whenever a new version comes along in future it's just this again:</p> <pre><code>gem update rails </code></pre>

    1. COWow... I so appreciate this write-up. Thanks! Unfortunately, I'm already stuck. Here's the response in terminal after I run your first step: ERROR: could not find gem rubygems_update locally or in a repository Yeesh... what's going on here? Maybe the trouble I'm having is an indication of a larger issue. Any thoughts?

    2. COIt's my fault, the RubyGems upgrade commands weren't quite right. I've now fixed the listing in my original post.

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.
