GridFieldRelationHandler
This module provides two GridField
components
that aid in managing relationships within SilverStripe. The
GridFieldHasOneRelationHandler
component allows a SS_List
to be used to select the value of a has_one
relation and the GridFieldManyRelationHandler
component manages a RelationList
., (*1)
Installation
If the version of SilverStripe you are running is earlier than 3.0.3, first apply this patch to GridFieldPaginator
., (*2)
Download this module and extract it into your site's root folder. Flush your site's manifest by visiting
http://yoursite.com/?flush=1. These components are now ready for use., (*3)
GridFieldHasOneRelationHandler
, (*4)
The GridFieldHasOneRelationHandler
component provides radio buttons for selecting the object that the
has_one points to. Its constructor takes the object the relation exists on, the name of the relation and
an optional target fragment which describes the position of the save relation button., (*5)
Example
:::php
$config->addComponent(new GridFieldHasOneRelationHandler($this, 'MainImage'));
GridFieldManyRelationHandler
, (*6)
The GridFieldManyRelationHandler
component provides check boxes for selecting the objects that a
has_many or many_many point to. Its constructor takes an optional target fragment which describes
the position of the save relation button., (*7)
If your GridField
also has a GridFieldPaginator
component, this component must be inserted before
it for the pagination to work properly., (*8)
Example
:::php
// The second argument here ensures that this component is placed before any GridFieldPaginator
$config->addComponent(new GridFieldManyRelationHandler(), 'GridFieldPaginator');
