Control output of object relations

Monday 03 March 2008 3:35:53 pm

New user question. I've created a class called "animal" and am using a object relations to store images associated with the animal.

Using the code below I can output the photos, however, I'd like to output just the first photo instead of all of them. I've searched the forum carefully but cannot find a proper solution. Please advise. Thanks!

		{def $nodes=fetch( 'content', 'list',
        hash( 'parent_node_id', 59,
              'depth', 1 ) )}
 		{foreach $nodes as $node}
			<div id="animal-listing">
				<div id="animal-head">
					<h1>{$node.name|wash} {attribute_view_gui attribute=$node.object.data_map.genestar_rating}/{attribute_view_gui attribute=$node.object.data_map.genestar_rating_max} <img style="vertical-align:middle" src={'genestar-logo.gif'|ezimage()} alt="GeneStar Logo" /></h1>
					<div id="price">{attribute_view_gui attribute=$node.object.data_map.price}</div> {* price *}
				</div> {* animal-head *}
				<div id="animal-photo">
					{attribute_view_gui attribute=$node.object.data_map.photography}
				</div> {* animal-photo *}
			</div> {* animal-listing *}
		{/foreach}

Felix,

Thanks for your answer. It wasn't quite was I was looking for. Adding the limit does return one record, however, I'm looking to return the first image of an object relation. So, if I put the limit of 1 in there, I get just one record returned whereas I'd like all records (animals) displayed with the first related photo.

$node.object.data_map.photography is an object relations that contains multiple photos. I need a way to get just the first image out of it.

Hopefully that is clearer.

Thanks!

Xavier,

Thanks for the reply. That tip helped me figure it out. Don't know if this is the most efficient solution, but this is the code:

{foreach $node.data_map.photography.content.relation_list as $relation}
     {def $obj=fetch('content', 'object',
			hash('object_id', $relation.contentobject_id))}
			{attribute_view_gui attribute=$obj.data_map.image image_class='medium'}		
	{undef $obj}
	{break}
{/foreach}
