    <p><strong>Edit</strong></p> <p>The original question was somewhat confusing and seemed to conflate Github with Rails. My answer below aimed to clarify the difference. The changes/clarifications made to the question later (after I posted my answer) have lead to the answer below to no longer respond to the question as (now) posted, but I cannot delete the answer as it has been marked as accepted...</p> <p>==================================</p> <p>It's hard to tell from the wording, but I think you're confused about several languages/tools that are found in Rails. Maybe this will help:</p> <ul> <li>Git (<a href="http://gitscm.org/)is" rel="nofollow noreferrer">http://gitscm.org/)is</a> a version control tool (<a href="http://en.wikipedia.org/wiki/Revision_control" rel="nofollow noreferrer">http://en.wikipedia.org/wiki/Revision_control</a>) used frequently in Rails projects. It's used to manage the source code in your projects (versions, branches with different functions, etc.)</li> <li>Github (<a href="https://github.com" rel="nofollow noreferrer">https://github.com</a>) is a place you can store source code that is managed with Git</li> <li>the default language used in Rails views is called ERB (introduction example here: <a href="http://thinkvitamin.com/code/rails-views-erb-part-1/" rel="nofollow noreferrer">http://thinkvitamin.com/code/rails-views-erb-part-1/</a>)</li> <li>rails 3.1 uses Sass to create CSS files by default (<a href="http://sass-lang.com/" rel="nofollow noreferrer">http://sass-lang.com/</a>)</li> </ul> <p>Those are the languages you've mentioned having trouble with, and they're a portion of the languages you'll need to familiarize yourself with if you want to use Rails to its full extent.</p> <p>You can learn more about Rails online (for example: <a href="http://ruby.railstutorial.org/" rel="nofollow noreferrer">http://ruby.railstutorial.org/</a>, <a href="http://railscasts.com/" rel="nofollow noreferrer">http://railscasts.com/</a>), or with books (<a href="http://pragprog.com/book/rails4/agile-web-development-with-rails" rel="nofollow noreferrer">http://pragprog.com/book/rails4/agile-web-development-with-rails</a> and <a href="http://www.manning.com/katz/" rel="nofollow noreferrer">http://www.manning.com/katz/</a> are 2 good books. The first one is easier for beginners, the second one goes into more detail and is for more advanced readers).</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.

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