Php 为什么在插入数据库时，Eloquent没有看到模型中的所有字段

我是Laravel开发的新手，正在尝试创建一个由SQLite数据库支持的雄辩模型。我的本地开发服务器上有以下代码，它正确地接受请求，构建模型，并将该模型保存为callback_requests表中的一行

下面是模型定义文件和数据库迁移文件。我已经使用

php artisan migrate:reset --force
php artisan migrate 

CallbackRequest.php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class CallbackRequest extends Model
{
    public $name;
    public $phone;
    public $email;
    public $preferredTime;
}

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateCallbackRequestsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('callback_requests', function (Blueprint $table) {
            $table->increments('id');
            $table->timestamps();
            $table->string('phone');
            $table->string('email');
            $table->string('preferredTime');
            $table->string('name');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('callback_requests');
    }
}

namespace App\Http\Controllers;

use App\Models\CallbackRequest;
use App\Mail\CallbackRequestMailable;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Mail\Mailable;
use Illuminate\Support\Facades\Mail;

class MailController extends Controller
{
    public function send(Request $request) 
    {
        $cbReq = new CallbackRequest();
        $cbReq->name = $request->get('name');
        $cbReq->email = $request->get('email');
        $cbReq->phone = $request->get('phone');
        $cbReq->preferredTime = $request->get('preferredTime');
        var_dump($cbReq);
        // save the entity to the database in case mail gets lost in transit
        $cbReq->save();
        // send an email to the address configured in the .env file
        $result = Mail::to(env("MAIL_CALLBACK_DELIVERY_ADDRESS"))->send(new CallbackRequestMailable($cbReq));
    }
}

创建回调请求表（迁移）。php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class CallbackRequest extends Model
{
    public $name;
    public $phone;
    public $email;
    public $preferredTime;
}

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateCallbackRequestsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('callback_requests', function (Blueprint $table) {
            $table->increments('id');
            $table->timestamps();
            $table->string('phone');
            $table->string('email');
            $table->string('preferredTime');
            $table->string('name');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('callback_requests');
    }
}

namespace App\Http\Controllers;

use App\Models\CallbackRequest;
use App\Mail\CallbackRequestMailable;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Mail\Mailable;
use Illuminate\Support\Facades\Mail;

class MailController extends Controller
{
    public function send(Request $request) 
    {
        $cbReq = new CallbackRequest();
        $cbReq->name = $request->get('name');
        $cbReq->email = $request->get('email');
        $cbReq->phone = $request->get('phone');
        $cbReq->preferredTime = $request->get('preferredTime');
        var_dump($cbReq);
        // save the entity to the database in case mail gets lost in transit
        $cbReq->save();
        // send an email to the address configured in the .env file
        $result = Mail::to(env("MAIL_CALLBACK_DELIVERY_ADDRESS"))->send(new CallbackRequestMailable($cbReq));
    }
}

这是控制器文件，我在其中创建模型的新实例，用传入请求中的值填充它，并将其保存到DB

MailController.php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class CallbackRequest extends Model
{
    public $name;
    public $phone;
    public $email;
    public $preferredTime;
}

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateCallbackRequestsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('callback_requests', function (Blueprint $table) {
            $table->increments('id');
            $table->timestamps();
            $table->string('phone');
            $table->string('email');
            $table->string('preferredTime');
            $table->string('name');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('callback_requests');
    }
}

namespace App\Http\Controllers;

use App\Models\CallbackRequest;
use App\Mail\CallbackRequestMailable;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Mail\Mailable;
use Illuminate\Support\Facades\Mail;

class MailController extends Controller
{
    public function send(Request $request) 
    {
        $cbReq = new CallbackRequest();
        $cbReq->name = $request->get('name');
        $cbReq->email = $request->get('email');
        $cbReq->phone = $request->get('phone');
        $cbReq->preferredTime = $request->get('preferredTime');
        var_dump($cbReq);
        // save the entity to the database in case mail gets lost in transit
        $cbReq->save();
        // send an email to the address configured in the .env file
        $result = Mail::to(env("MAIL_CALLBACK_DELIVERY_ADDRESS"))->send(new CallbackRequestMailable($cbReq));
    }
}

我已经转储了$cbReq变量的内容，以确保正确添加了值，我得到的输出（如下所示）表明它们已经添加了

object(App\Models\CallbackRequest)#222 (30) {
  ["name"]=>
  string(13) "Customer Name"
  ["phone"]=>
  string(9) "012345678"
  ["email"]=>
  string(14) "cust@email.com"
  ["preferredTime"]=>
  string(7) "morning"
  ["connection":protected]=>
  NULL
  ["table":protected]=>
  NULL
  ["primaryKey":protected]=>
  string(2) "id"
  ["keyType":protected]=>
  string(3) "int"
  ["incrementing"]=>
  bool(true)
  ["with":protected]=>
  array(0) {
  }
  ["withCount":protected]=>
  array(0) {
  }
  ["perPage":protected]=>
  int(15)
  ["exists"]=>
  bool(false)
  ["wasRecentlyCreated"]=>
  bool(false)
  ["attributes":protected]=>
  array(0) {
  }
  ["original":protected]=>
  array(0) {
  }
  ["changes":protected]=>
  array(0) {
  }
  ["casts":protected]=>
  array(0) {
  }
  ["dates":protected]=>
  array(0) {
  }
  ["dateFormat":protected]=>
  NULL
  ["appends":protected]=>
  array(0) {
  }
  ["dispatchesEvents":protected]=>
  array(0) {
  }
  ["observables":protected]=>
  array(0) {
  }
  ["relations":protected]=>
  array(0) {
  }
  ["touches":protected]=>
  array(0) {
  }
  ["timestamps"]=>
  bool(true)
  ["hidden":protected]=>
  array(0) {
  }
  ["visible":protected]=>
  array(0) {
  }
  ["fillable":protected]=>
  array(0) {
  }
  ["guarded":protected]=>
  array(1) {
    [0]=>
    string(1) "*"
  }
}

但是，当应用程序在保存时遇到错误时，会显示以下消息

{
    "message": "SQLSTATE[HY000]: General error: 1364 Field 'phone' doesn't have a default value (SQL: insert into     `callback_requests` (`updated_at`, `created_at`) values (2019-03-11 10:19:24, 2019-03-11 10:19:24))",
    "exception": "Illuminate\\Database\\QueryException",
    ...
}

它从错误消息中看起来好像Eloquent不知道自定义列，并且试图只填充自动递增ID和时间戳。奇怪的是，当我在本地服务器上运行相同的代码时，一切正常，只有当代码部署到测试服务器时，我才会遇到错误

对于这个冗长的问题我深表歉意，我已经尽量少提了，但没有遗漏任何相关的内容。如果您有任何建议，我们将不胜感激。

您需要从模型中删除您的属性。因此，删除所有这些：

public $name;
public $phone;
public $email;
public $preferredTime;

否则，当您设置

$model->phone=$request->phone

时，它会在对象上设置此属性，而不是在模型的

$attributes

数组中设置键，该数组将保存到数据库中

这是由于Laravel钩住PHP magic方法来设置模型的属性。这是基本模型类中的内容：

/**
 * Dynamically set attributes on the model.
 *
 * @param  string  $key
 * @param  mixed  $value
 * @return void
 */
public function __set($key, $value)
{
    $this->setAttribute($key, $value);
}

如果IDE的IntelliSense（自动完成）具有这些属性，则仍然可以使用docblock提示动态属性：

/**
 * Class CallbackRequest
 *
 * @property-read string name
 * @property-read string phone
 * @property-read string email
 * @property-read string preferredTime
 */
class CallbackRequest extends Model {}

或者使用类似于自动化此步骤的软件包。

感谢您的快速响应，特别是解释了问题的根本原因！那很有魅力。
