README

本模块提供了两个 GridField 组件，有助于管理 SilverStripe 内部的关系。 GridFieldHasOneRelationHandler 组件允许使用 SS_List 来选择 has_one 关系的值，而 GridFieldManyRelationHandler 组件则管理 RelationList。

安装

如果您正在运行的 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网站的根目录中。通过访问 http://yoursite.com/?flush=1 来刷新您网站的清单。这些组件现在可以使用了。

GridFieldHasOneRelationHandler

GridFieldHasOneRelationHandler 组件提供单选按钮以选择 has_one 指向的对象。其构造函数接收存在关系的对象、关系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。其构造函数接收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 也包含 GridFieldPaginator 组件，则此组件必须插入到它之前，以便正确地进行分页。

示例

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