    1. COYou're not sending anything named "users", so I'm not sure why you'd expect it to be anything other than null. Did you try sending an object with a `users` key with a collection of users?

    3. CO... Why would you want to send the JSON you show? It would be better to send something named "users" with an array of users; e.g. something like `{ "users": [{"userName": "xxx", etc.}, {"userName": "yyy", etc.}]}` or something similar (untested).

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.
