Using attribute_filter on related object attributes

Tuesday 25 May 2004 12:04:22 am

Hi everyone,

Some background: A Gig is an event where a Band plays at a Venue. When looking at the details of a Gig, I want to be able to display a short list of all other Gigs at the same Venue, and all other Gigs featuring the same Band.

The Venue and Band are both objects, and are stored as related object attributes of a Gig.

To display a list of Gigs at the same Venue I'm using this code:

    {let venue=fetch( 'content', 'object', hash( 'object_id', $node.object.data_map.venue.data_int ) )}

    <b>More events at the {$venue.name}</b><br>
    {section loop=fetch( 'content', 'tree',
        hash(	'parent_node_id',	'46',
            'class_filter_type',	'include',
            'class_filter_array',	array( 'gig' ),
            'attribute_filter',	array( 'or', array( 'gig/venue', '=', '$venue.id' ))
    ) )}

This gives me nothing. If I remove the attribute filter I get all the gigs. What I really need to do is filter based on the object id, so using something like "gig/venue.id" in the filter, but this doesn't seem to work.

Does anyone have any ideas how I can do this?

It looks as if the class filtering and the attribute filtering are mutually exclusive (class filtering is implied by the attribute filter) so removing this should work.

{let venue=fetch( 'content', 'object', hash( 'object_id', $node.object.data_map.venue.data_int ) )}

<b>More events at the {$venue.name}</b><br>
{section loop=fetch( 'content', 'tree',
hash( 'parent_node_id', '46',
      'attribute_filter', array(array( 'gig/venue', '=', $venue.id ))
) )}

Should do the trick.
