The ezobjectrelation datatype (Object relation) #

Class eZObjectRelationType in kernel/classes/datatypes/ezobjectrelation/ezobjectrelationtype.php; identifier ezobjectrelation, listed in settings/content.ini [DataTypeSettings] AvailableDataTypes[].

What it stores #

The columns of the attribute tables its class reads or writes: data_int, data_int1, data_int2, data_int3, data_text, data_text5 (data_text, data_int, data_float and sort_key_* are the object attribute's; data_text1 ... data_int4 the class attribute's settings). Found by reading the class: a heuristic. Sorting: sortKeyType() returns int. It is indexed by the search.

In templates #

my_attribute stands for the identifier of an attribute of this type in your class:

{def $attribute = $node.data_map.my_attribute}
{if $attribute.has_content}
    {attribute_view_gui attribute=$attribute}
{/if}
{* the value as the datatype returns it (objectAttributeContent()) *}
{$attribute.content|attribute( show, 1 )}

The shipped template that shows it (attribute_view_gui), design/standard/templates/content/datatype/view/ezobjectrelation.tpl:

{* DO NOT EDIT THIS FILE! Use an override template instead. *}
{if and( $attribute.content, or( $attribute.content.can_read, $attribute.content.can_view_embed ), $attribute.content.has_visible_node )}
    {content_view_gui view=text_linked content_object=$attribute.content}
{else}
   {'No relation'|i18n( 'design/standard/content/datatype' )}
{/if}

The shipped template that edits it (attribute_edit_gui), design/standard/templates/content/datatype/edit/ezobjectrelation.tpl (first 25 lines):

{* DO NOT EDIT THIS FILE! Use an override template instead. *}
{default attribute_base=ContentObjectAttribute}
{let class_content=$attribute.contentclass_attribute.content}

{switch match=$class_content.selection_type}

{* Browse. *}
{case match=0}
<div class="block" id="ezobjectrelation_browse_{$attribute.id}">

<table class="list{if $attribute.content|not} hide{/if}" cellspacing="0">
<thead>
<tr>
    <th>{'Name'|i18n( 'design/standard/content/datatype' )}</th>
    <th>{'Type'|i18n( 'design/standard/content/datatype' )}</th>
    <th>{'Section'|i18n( 'design/standard/content/datatype' )}</th>
    <th>{'Published'|i18n( 'design/standard/content/datatype' )}</th>
</tr>
</thead>
<tbody>
<tr class="bglight">
{if and( $attribute.content, or( $attribute.content.can_read, $attribute.content.can_view_embed ) )}

    {* Name *}
    <td>{$attribute.content.name|wash()}</td>

Override them for one class attribute in an override.ini.append.php with Source=content/datatype/view/ezobjectrelation.tpl and a match on attribute_identifier (see A template override).
