无法将变量从组件控制器传递给邮件- Laravel

Question

当我试图创建一个邀请并通过邮件发送链接给用户时，我收到了一个错误。我能够成功地发送邮件，成功的创建邀请。但是，当我试图将变量$invitation传递给App\Mail\InvitationCreated时，即使在可邮件(例如__construct(Invitation $invitation) )中初始化变量之后，也会出现错误。

请帮助我理解这里的问题。

App\Models\Invitation

class Invitation extends Model
{
    use HasFactory;

    protected $fillable = [
        'email', 'invitation_token', 'registered_at',
    ];

    public function generateInvitationToken() {
        $this->invitation_token = substr(md5(rand(0, 9) . $this->email . time()), 0, 32);
    }

    public function getLink() {
        return urldecode(route('register') . '?invitation_token=' . $this->invitation_token);
    }
}

App\Http\Livewire\InvitationController

use Illuminate\Support\Facades\Mail;

use App\Models\Invitation;
use App\Mail\InvitationCreated;

class InvitationController extends Component
{
    use WithPagination;

    public $showEditModal = false;
    public Invitation $invitation;

    protected $rules = [
        'invitation.email' => 'required | email | max:255 | unique:users,email',
    ];

    public function mount()
    {
        $this->invitation = new Invitation();
    }

    public function save()
    {
        $this->validate();
        $this->invitation->generateInvitationToken();
        $invitation = $this->invitation->save();
        $this->showEditModal = false;

        Mail::to($this->invitation->email)->send(new InvitationCreated($invitation));
    }
}

App\Http\Mail\InvitationCreated

use App\Models\Invitation;

class InvitationCreated extends Mailable
{
    use Queueable, SerializesModels;

    public function __construct(Invitation $invitation)
    {
        $this->invitation = $invitation;
    }

    public function build()
    {
        return $this->from('server@localhost.com')->view('emails.invite-created');
    }
}

resources\views\emails\invite-created

<p>Hi,</p>
<p>Someone has invited you to access their account.</p>
 
<a href="{{ $invitation->getLink() }}">Click here</a> to activate!

错误，我得到的是

Argument 1 passed to App\Mail\InvitationCreated::__construct() must be an instance of App\Models\Invitation, bool given, called in C:\xampp\htdocs\2020\app\Http\Livewire\Backend\UserManagement\InvitationController.php on line 54

Answer 1

尝尝这个

Mail::to($this->invitation->email)->send(new InvitationCreated($this->invitation));

$invitation到$this->invitation

在$invitation = $this->invitation->save();中，此代码返回真或假数据是否保存。

因此，您可以从公共属性instance of App\Models\Invitation $this->invitation中获取

为了将数据发送到邮件视图，您需要创建公共程序。

use App\Models\Invitation;

class InvitationCreated extends Mailable
{
    use Queueable, SerializesModels;

    public $invitation;

    public function __construct(Invitation $invitation)
    {
        $this->invitation = $invitation;
    }

    public function build()
    {
        return $this->from('server@localhost.com')->view('emails.invite-created');
    }
}
