Show pages

The show page renders one record from its declared attributes. Each attribute is a detail row, using the same formatters as the index, so a value renders the same way in both places.

attribute('title');
attribute('published', :format<boolean>);
attribute('body',      :display({ .body.substr(0, 200) }));
attribute('author');     # an association

A :display block computes the row value; otherwise the value is read from the column and run through the named :format.

An attribute value is HTML-escaped by default. Declare an attribute :html to render its value as trusted markup instead, bypassing escaping and any :format (see raw markup):

attribute('preview', :html, :display({ .rendered-html }));

Action panel#

A sidebar panel holds the per-record actions: Edit (links to the edit form), Delete (a destroying form with a confirmation), and any custom member actions declared for the resource. Each control is hidden when the authorization policy forbids it. See Destroy, batch, and custom actions.

Associations#

When an attribute names an association, the show page renders it from the relationship rather than as a column:

• A belongs-to (or has-one) attribute renders as a link to the associated record's admin show page, when that model is itself a registered resource. A missing association renders a dash, never a broken link.
• A has-many (or has-and-belongs-to-many) attribute renders as a compact sub-table, each row linking into the associated resource, capped with an "and N more" line. A :display block overrides this, summarising the collection however you like (for example a comma-joined string) in place of the per-record links. The summary is HTML-escaped unless the attribute is declared :html.

Association kind and target are detected through the ORM's reflection, so the link targets are resolved from the registry by model.
