php - 将自定义操作的按钮添加到 ModelAdmin

Question

在 Silverstripe 3 中使用 ModelAdmin 管理 Dataobject 时，我想知道如何将自定义操作的按钮添加到 ListView 和编辑页面.

通过在 ModelAdmin 的 GridField 类上设置 ItemRequest，我已经成功地为编辑页面添加了一个操作按钮使用以下代码:

class MyModelAdmin extends ModelAdmin
{
    //...

    public function getEditForm($id = null, $fields = null)
    {
        $form = parent::getEditForm($id, $fields);
        $form
            ->Fields()
            ->fieldByName($this->sanitiseClassName($this->modelClass))
            ->getConfig()
            ->getComponentByType('GridFieldDetailForm')
            ->setItemRequestClass('MyModelGridFieldDetailForm_ItemRequest');

        return $form;
    }

}

MyModelGridFieldDetailForm_ItemRequest.php

class MyModelGridFieldDetailForm_ItemRequest extends GridFieldDetailForm_ItemRequest
{
    function ItemEditForm()
    {
        $form = parent::ItemEditForm();
        $formActions = $form->Actions();

        $button = FormAction::create('myAction');
        $button->setTitle('My Custom Action');
        $button->addExtraClass('ss-ui-action-constructive');
        $formActions->push($button);

        $form->setActions($formActions);
        return $form;
    }


    function myAction($data, $form)
    {

        //do things

        $form->sessionMessage('My Action has been successful', 'good');

        if ($this->gridField->getList()->byId($this->record->ID)) {
            return $this->edit(Controller::curr()->getRequest());
        } else {
            $noActionURL = Controller::curr()->removeAction($data['url']);
            Controller::curr()->getRequest()->addHeader('X-Pjax', 'Content');
            return Controller::curr()->redirect($noActionURL, 302);
        }
    }

}

那么问题是:

我可以在 ModelAdmin GridField ListView 中为相同的操作设置一个按钮吗？使其出现在编辑和删除按钮旁边:

Answer 1

您可以通过创建自己的 GridFieldComponent 实现 GridField_ColumnProvider 和 GridField_ActionProvider 来做到这一点。

在您的情况下，您几乎可以复制 GridFieldDeleteAction 类并使用您自己的 GridField_FormAction 编辑 getColumnContent() 并编辑 handleAction () 施展你的魔法。
