    <p>Ok, I hesitated to use <code>rvm</code> as it seemed to be aimed at solving problems I didn't intend to have (multiple ruby versions? c'mon, I just want to play with rails...) and installing from source is generally something I want to avoid...</p> <p>Anyway, I gave in and followed along with <a href="http://rvm.beginrescueend.com/rvm/install/" rel="noreferrer">http://rvm.beginrescueend.com/rvm/install/</a></p> <pre><code>$ bash &lt; &lt;( curl http://rvm.beginrescueend.com/releases/rvm-install-head ) </code></pre> <p>Then (mostly suggested by the output of the above, but I needed to add <code>libmysqlclient-dev</code>):</p> <pre><code>$ sudo aptitude install build-essential bison openssl libreadline5 \ libreadline5-dev curl git zlib1g zlib1g-dev \ libssl-dev libsqlite3-0 libsqlite3-dev sqlite3 \ libxml2-dev libmysqlclient-dev </code></pre> <p>Then I edited my <code>.bashrc</code> as required and opened a new terminal.</p> <pre><code>$ rvm install 1.9.2 $ rvm --default use 1.9.2 $ ruby -v ruby 1.9.2p0 (2010-08-18 revision 29036) [i686-linux] $ gem install rails $ rails -v Rails 3.0.1 </code></pre> <p>After creating a new project, I still had a few things to do to make it work:</p> <pre><code>$ rails new myproject --database=mysql $ cd myproject $ emacs config/database.yml # set passwords $ bundle install $ rake db:create $ rails server </code></pre> <p>And finally it all seems to be working. I hope that helps someone else, it certainly wasn't a particularly pleasant intro to a framework. I've reordered the commands I actually entered to avoid double handling for anyone following along.</p>

    2. COTried this on ubuntu 10.04. I did: `rvm install 1.8.7`, then `rvm use --default 1.8.7`, then `rvm rubygems current`, and finally: `gem install rails`. It installed a bunch of stuff, but I then got: ERROR: While generating documentation for builder-2.1.2 ... MESSAGE: Unhandled special: Special: type=17, text="<!-- HI -->" ... RDOC args: --ri --op /opt/standingcloud/.rvm/gems/ruby-1.8.7-p334/doc/builder-2.1.2/ri --title Builder -- Easy XML Building --main README --line-numbers lib CHANGES Rakefile README doc/releases/builder-1.2.4.rdoc doc/releases/builder-2.0.0.rdoc [...]

    3. CO@TrinitronX - i think it should be `rvm --default use 1.8.7`. Without that you're probably using the built in ruby and getting the same error as when i tried to install rails without rvm.

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).
