    1. COYou have your ajax call outside of the scope of your ready function. So the ajax call attempts to execute before the document is ready, rendering the `url` variable as undefined, being that it is compiled at the execution of the document ready state.

    2. CO`url` is **local** to the `ready` callback. Why don't you put all your code inside the callback? And additionally, at the moment you execute `$.ajax`, the `ready` callback wasn't called yet.

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.
