自动生成SilverStripe管理链接

问题描述 投票：0回答：2

所以我有一个 DataObject，我通过模型管理通过标准网格字段（使用 Silverstripe 4）进行管理

我希望能够生成一个链接来直接由管理员编辑此对象。如果我手动输入 ModelAdmin URL，我可以做到这一点，但这似乎不是很动态（如果我们将来更改管理 URL，那么该方法将被破坏）。

我尝试实现以下内容：

class MyObject extends DataObject
{
    public function EditLink()
    {
        $classname = str_replace('\\', '-', $this->owner->ClassName);
        $admin = OrderAdmin::singleton();
        $fields = $admin->getEditForm()->Fields();
        $grid = $fields
            ->fieldByName($classsname);

        return Controller::join_links(
            $grid->Link("item"),
            $this->owner->ID,
            "edit"
        );
    }
}

但这会输出此错误和堆栈跟踪：

[Emergency] Uncaught InvalidArgumentException: SilverStripe\ORM\DataObject is not a subclass of DataObject

我假设这是因为我在创建 ModelAdmin 时没有将正确的响应对象传递给 ModelAdmin，所以不确定要使用什么 ModelClass？

有人对实现这一点的首选方式有任何想法吗？

这应该适用于 SilverStripe 3 和 4（在 3.6 和 4.0 上测试）

class MyObject extends DataObject
{
    public function EditLink()
    {
        $classname = str_replace('\\', '-', singleton($this->owner->ClassName)->i18n_plural_name());
        $admin = OrderAdmin::singleton();
        $fields = $admin->getEditForm()->Fields();
        $grid = $fields->dataFieldByName($classname);

        return Controller::join_links(
            $grid->Link("item"),
            $this->owner->ID,
            "edit"
        );
    }
}

对原始内容所做的更改包括

  • 使用复数版本的ClassName
  • 修复请求网格时
    $classname
    的拼写错误
  • 使用 
    ->dataFieldByName()
    而不是 
    ->fieldByName()

注意：SilverStripe 4.0 使用正确的命名空间，因此您还需要确保为 DataObject 使用正确的命名空间。

例如

namespace MySite;

use SilverStripe\ORM\DataObject;

class MyObject extends DataObject
{

对于 SilverStripe 5，有一个新的 

CMSEditLinkExtension
可以涵盖此用例。它还处理通过相关对象的链接。

https://docs.silverstripe.org/en/5/developer_guides/model/managing_records/#getting-an-edit-link/

// app/src/Model/MyModel.php
namespace App\Model;

use SilverStripe\Admin\CMSEditLinkExtension;
use SilverStripe\ORM\DataObject;

class MyModel extends DataObject
{
    private static string $cms_edit_owner = 'Parent';

    private static $has_one = [
        'Parent' => MyParentModel::class,
    ];

    private static $extensions = [
        CMSEditLinkExtension::class,
    ];
}

// app/src/Model/MyParentModel.php
namespace App\Model;

use App\Admin\MyModelAdmin;
use SilverStripe\Admin\CMSEditLinkExtension;
use SilverStripe\ORM\DataObject;

class MyParentModel extends DataObject
{
    private static string $cms_edit_owner = MyModelAdmin::class;

    private static $has_many = [
        'Children' => MyModel::class,
    ];

    private static $extensions = [
        CMSEditLinkExtension::class,
    ];
}

然后您可以简单地在任何 

CMSEditLink()
或 
MyModel
上使用 
MyParentModel
。
