    <p>I've been wondering this for a while now, but what is the best way to ensure that in a web app (RoR, Sinatra, PHP, anything) that when you are creating links (either generating with a method, or writing in by hand) that they go to the proper place whether you are on the root of a domain or not: <a href="http://www.example.com/" rel="nofollow noreferrer">http://www.example.com/</a> or <a href="http://www.example.com/this/is/where/the/app/is/" rel="nofollow noreferrer">http://www.example.com/this/is/where/the/app/is/</a></p> <p>My thoughts are get the end-user to specify a document root somewhere in the config of your app, and use that, however I'm trying to think of a nice way to do it without the end-user having to configure anything.</p> <p>Edit: By end-user, I mean the person setting up the application on a server.</p> <p>Edit: I can use the beginning '/' to always get the link relative to the domain, but the problem is what if the app itself is not at the root, but some place like <a href="http://www.example.com/this/is/where/the/app/is/" rel="nofollow noreferrer">http://www.example.com/this/is/where/the/app/is/</a> so i want to say <code>gen_link('/')</code> and have it return <code>/this/is/where/the/app/is/</code> or <code>gen_link('/some/thing')</code> and return <code>/this/is/where/the/app/is/some/thing</code></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.
