Laravel 9.x 联系表无法连接到 class

Question

我正在尝试制作联系表。主要思想是用户发送数据，我将数据保存到数据库，我从数据库中获取数据，我将数据作为电子邮件发送。

我正在学习教程 -> https://www.positronx.io/laravel-contact-form-example-tutorial/

当我试图访问我的控制器上的 classes 时，它找不到它。

Controller says this

But I have the file here

当我运行我有这个代码时 -> Cannot instantiate abstract class Illuminate\Database\Eloquent\Model

ContactUsFormController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use app\Models\Contact;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Mail;

class ContactUsFormController extends Controller
{
    //create contact form
    public function createForm(Request $req){
        return view('contact');
    }
    //store contact form data
    public function ContactUsForm(Request $req){
        //form validation 
        $this->validate($req,[
            'name' => 'required',
            'email' => 'required | email',
            'subject' => 'required',
            'message' => 'required'
        ]);
        //store data in database
        Model::create($req->All());
        //send mail to admin
        Mail::send('mail',array(
            'name' => $req->get('name'),
            'email' => $req->get('email'),
            'subject' => $req->get('subject'),
            'message' => $req->get('message')
        ),function($message) use ($req){
            $message->from($req->email);
            $message->to('MyMail@example.com','admin')->subject($req->get('subject'));
        });
        return back()->with('success', 'We have recieved your message');
    }
}

这个让我思考。在教程中，他没有将任何代码写入此文件，但仍然从那里调用 class。 app\Mails\contact.php

<?php
namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
class contact extends Mailable
{
    use Queueable, SerializesModels;
    public function __construct()
    {
        //
    }
  public function build()
    {
        return $this->view('view.name');
    }
}

app\Models\Contact.php

namespace App\Mail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Contact extends Model
{
    use HasFactory;
    public $fillable = ['name', 'email', 'subject', 'message'];

}

我有错字吗？我缺少什么？对不起，我是初学者

Answer 1

你称之为Model::create();模型的问题只是一个抽象class，而不是你的具体模型

替换

Model::create($req->All());

和

Contact::create($req->All());

同时将联系人模型中的 namespace App\Mail; 更改为命名空间 App\Models;

要了解有关 Mail facade 的更多信息，请查看此
