    1. COIt'd be a lot easier to answer if you printed the output from `Dumper($item->{author})` - matter of fact, doing so might tell you what the problem is in the first place.

    2. COSince the answer didn't state this outright - any time when you print the expression's value in Perl and you get `HASH(address)`, it means that whatever you had was a hashref.

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.
