26 C<maybe_link_view> takes something returned from the database - either
27 some ordinary data, or an object in a related class expanded by a
28 has-a relationship. If it is an object, it constructs a link to the view
29 command for that object. Otherwise, it just displays the data.

35 IF object.table; # It's an object, i.e. a has-a
36 link(object.table, "view", object.id, object);
47 C<display_line> is used in the list template to display a row from the
48 database, by iterating over the columns and displaying the data for each
49 column. It misses out the C<id> column by default, and magically
50 URLifies columns called C<url>. This may be considered too much magic

89 This takes an object, and looks up the C<related_accessors>; this should
90 give a list of accessors that can be called to get a list of related
91 objects. It then displays a title for that accessor, (i.e. "Beers" for a
92 brewery) calls the accesor, and displays a list of the results.
