小编tho*_*son的帖子

我正在尝试在我的 Ubuntu 20.04.3 LTS 桌面上使用最新版本的 laravel sail 设置 xdebug，

即
PHP 8.1
Laravel 9

.env 文件包含以下提到的详细信息

SAIL_XDEBUG_MODE=develop,debug
SAIL_XDEBUG_CONFIG="client_host=172.23.0.1"

但当我跑步时sail debug migrate，返回

Xdebug: [Step Debug] Time-out connecting to debugging client, waited: 200 ms. Tried: 172.23.0.1:9003 (through xdebug.client_host/xdebug.client_port)

当我尝试查找 IP 时，每次
docker inspect -f {{range.NetworkSettings.Networks}}{{.Gateway}}{{end}} <container-name> 返回不同的 IP（例如 172.25.0.1）时它都会发生变化

我Customer DataObject通过扩展创建了一个Member. 与 aCustomer有many_many数据关系Package DataObject。

我想Credits在基于表中的字段通过 CMS 链接/取消链接Customer DataObjecta 时增加/减少一个字段。PackageLimitPackage

顾客

class Customer extends Member {

    private static $db = array(
        'Gender' => 'Varchar(2)',
        'DateOfBirth' => 'Date',
        'Featured' => 'Boolean',
        'Credits' => 'Int'
    );

    private static $many_many = array(
        'Packages' => 'Package'
    );

    public function getCMSFields() {

        $fields = new FieldList();

        $config = GridFieldConfig_RelationEditor::create();
        $config->removeComponentsByType('GridFieldAddNewButton');

        $packageField = new GridField(
            'Packages',
            'Package',
            $this->Packages(),
            $config …

我有'Resouce'数据对象如下所示,附件为has_one关系.我想在删除'resource'对象时删除附件.

但我得到的是致命错误:在非对象上调用成员函数delete()

<?php 
class Resource extends DataObject
{ 
private static $db = array (
    'Name' => 'Varchar(200)',
    'Description' => 'Text',
    'Category' => "Enum('Data, Drafts, Drawings, Reports, Images, Other')",
    'SortOrder' => 'Int'
);

private static $has_one = array (
    'Attachment' => 'File',
    'ResourcePage' => 'ResourcePage'
);


public function onBeforeDelete()
{
    $myAttachment = $this->Attachment();
    $file = DataObject::get_by_id('File', $myAttachment->ID); //we have to make sure it is a Dataobject object      
    $file->delete();
    $file->destroy();       
    return parent::onBeforeDelete();                    
}

}
