Question

我正在尝试更改account对象的某些属性值。我正在尝试在domain和password

上设置一个值

当我在将对象发送到前端（使用vue）之前记录其对象时，该对象似乎已根据我的需要进行了修改，但是当我在浏览器中console.log()将其属性值设置为null时。

我正在使用Laravel Excel创建帐户。创建帐户后，我将事件与侦听器一起使用，以通过pusher将帐户对象发送到视图。

如何正确执行此操作？

帐户导入

class AccountsImport implements ToCollection, withHeadingRow
{
    use Importable;

    private $data;

    public function __construct(array $data = [])
    {
        $this->data = $data;
    }

    public function collection(Collection $rows)
    {
        $rows->each(function ($row, $key) {
           $account = Account::create(array_merge([
                'name' => mb_convert_encoding($row['student'], "UTF-8", mb_detect_encoding($row['student'], "UTF-8, ISO-8859-1, ISO-8859-15", true)),
                'email' => $row['school_e_mailadres'],
            ], $this->data));
            event(new AccountCreation($account));
        });
    }
}

AccountCreation事件被触发并且SetHostingAccount侦听器将运行

public function handle(AccountCreation $event) 
{
    $generator = new ComputerPasswordGenerator();
    $generator->setUppercase()->setLowercase()->setNumbers()->setSymbols(false)->setLength(20);
    $password = $generator->generatePassword();

    $domain = preg_replace('/\s+/', '.', mb_strtolower($event->account->name . ' mtantwerp.eu'));
    $event->account->{"domain"} = $domain;
    $event->account->{"password"} = $password;

    \Log::debug($event->account);

    return $event->account; 
}

Vue

 created() {
    Echo.channel("account-channel").listen("AccountCreation", e => {
      console.log(e.account);
      this.accounts.unshift(e.account);
    });      
  }

记录结果

\Log::debug($event->account)

的示例结果

{"name":"John Doe","email":"john.doe@student.kdg.be","package":"KDG student","id":577,"domain":"john.doe.mtantwerp.eu","password":"r5RSEvQBYnTF7RkPtL8Y"}

Console.log(e.account)在视图中

Object
domain: null
email: "john.doe@student.kdg.be"
id: 703
name: "Doe John"
package: "KDG student"
password: null
status: "created"

似乎您没有将数据持久保存到模型中。

public function handle(AccountCreation $event) 
{
    $generator = new ComputerPasswordGenerator();
    $generator->setUppercase()->setLowercase()->setNumbers()->setSymbols(false)->setLength(20);
    $password = $generator->generatePassword();

    $domain = preg_replace('/\s+/', '.', mb_strtolower($event->account->name . ' mtantwerp.eu'));
    $event->account->{"domain"} = $domain;
    $event->account->{"password"} = $password;

    // persist 
    $event->account->save();

    return $event->account; 
}

编辑：我认为您可以通过两种方式来处理此问题。

您可以在更新帐户详细信息后重新广播该活动：

public function handle(AccountCreation $event) 
{
    $generator = new ComputerPasswordGenerator();
    $generator->setUppercase()->setLowercase()->setNumbers()->setSymbols(false)->setLength(20);
    $password = $generator->generatePassword();

    $domain = preg_replace('/\s+/', '.', mb_strtolower($event->account->name . ' mtantwerp.eu'));
    $event->account->{"domain"} = $domain;
    $event->account->{"password"} = $password;

    // persist 
    $event->account->save();

    // broadcast will have updated account details 
    // after it was persisted
    broadcast($event);

    return $event->account; 
}

在这种情况下，您还需要检查帐户是否在Vue组件上具有域。

if(e.account.domain) {
    this.accounts.unshift(e.account);
}

这应该有效。但是，我希望您考虑创建一个新事件，以更好地描述您打算做的事情。在这种情况下，正在更新帐户。因此，您将创建一个新的AccountWasUpdated事件，而您将让Echo听它。

public function handle(AccountCreation $event) 
{
    $generator = new ComputerPasswordGenerator();
    $generator->setUppercase()->setLowercase()->setNumbers()->setSymbols(false)->setLength(20);
    $password = $generator->generatePassword();

    $domain = preg_replace('/\s+/', '.', mb_strtolower($event->account->name . ' mtantwerp.eu'));
    $event->account->{"domain"} = $domain;
    $event->account->{"password"} = $password;

    // persist 
    $event->account->save();

    event(new AccountWasUpdated($event->account)); 

    return $event->account; 
}

它不是让Echo监听AccountCreation事件，而是监听AccountWasUpdated事件，它将包含新的Account Object。

更改对象属性值在视图中返回null
