admin - 自动生成 SilverStripe 管理链接

标签 admin silverstripe silverstripe-4

所以我有一个数据对象，我通过标准网格字段(使用 Silverstripe 4)通过模型管理管理

我希望能够生成一个链接以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，但这看起来不是很动态(如果我们将来更改管理 URL，那么该方法就会中断)。

我已尝试实现以下内容:

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它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？

有没有人对实现这个的首选方式有任何想法？

最佳答案

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"
        );
    }
}

对原件所做的更改包括

  • 使用类名的复数形式
  • 修复请求网格时的 $classname 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
{
