README

此模块提供了两个GridField组件，有助于在SilverStripe中管理关系。 GridFieldHasOneRelationHandler组件允许使用SS_List选择has_one关系的值，而GridFieldManyRelationHandler组件管理RelationList。

安装

如果您运行的SilverStripe版本早于3.0.3，首先将此补丁应用到GridFieldPaginator。

下载此模块并将其解压到您的站点根目录中。通过访问http://yoursite.com/?flush=1刷新您站点的清单。这些组件现在可用于使用。

GridFieldHasOneRelationHandler

GridFieldHasOneRelationHandler组件提供单选按钮以选择has_one指向的对象。其构造函数接受关系存在的对象、关系的名称以及一个可选的目标片段，该片段描述了保存关系按钮的位置。

示例

:::php
$config->addComponent(new GridFieldHasOneRelationHandler($this, 'MainImage'));

GridFieldManyRelationHandler

GridFieldManyRelationHandler组件提供复选框以选择has_many或many_many指向的对象。其构造函数接受一个可选的目标片段，该片段描述了保存关系按钮的位置。

如果您的GridField也具有GridFieldPaginator组件，则此组件必须在其之前插入，以便正确工作分页。

示例

:::php
// The second argument here ensures that this component is placed before any GridFieldPaginator
$config->addComponent(new GridFieldManyRelationHandler(), 'GridFieldPaginator');
