所以我有一个DataObject，我通过模型管理通过标准的网格(使用Silverstripe4)来管理它

我希望能够生成一个链接，直接在管理员编辑此对象。如果我手动输入admin，我可以做到这一点，但这似乎不是很动态(如果我们在将来更改ModelAdmin的URL，那么这种方法将会中断)。

我已经尝试实现了以下几点：

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"
        );
    }
}

但是这会输出这个错误& stacktrace：

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

POST /as-plumbing-app-v2/admin/jobs/Job/EditForm/field/Job/item/1/ItemEditForm/

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

有没有人对实现这一功能的首选方法有什么想法？

silverstripe-4

admin

silverstripe

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"
        );
    }
}

对原始文件所做的更改包括

当使用ClassName

Fixing而不是->fieldByName()

请求网格

时，使用多个版本的网格拼写错误的网格

$classname

注意: SilverStripe 4.0使用了正确的名称空间，因此您还需要确保为DataObject使用正确的名称空间。

例如。

namespace MySite;

use SilverStripe\ORM\DataObject;

class MyObject extends DataObject
{
...
