    2. COI got the feeling that you confuse get and post in rest declaration. I don't know rest much (please provide a good link, I would appreciate) but you are describing your params as part of the uri (as in a get method) and you want to use post. I am pretty sure your service would work with id passed in the url.

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.
