Question

我正在尝试播种数据库，但cmd仅返回此FatalThrowableError错误：“找不到类应用程序\产品”

这是我的迁移文件

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $fillable = ['imagepath','title','description','price'];
}

这是我的提供商文件

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $fillable = ['imagepath','title','description','price'];
}

这是我的种子文件

<?php

use Illuminate\Support\Facades\Product;
use Illuminate\Database\Seeder;

class ProductTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $product=new \app\Product([
            'imagepath' =>'https://cdn.djcity.com.au/wp-content/uploads/2016/07/14082413/launchkey-mini-elevated_0.jpg',
            'title' =>'Novation LaunchKey Mini mk2 MIDI',
            'description' =>'issa book',
            'price' =>'125'
        ]);
        $product ->save();

cmd仅返回未找到$product=new \app\Product类的信息

这是我的SQLSTATE [42S22]的迁移文件，尝试播种时出现问题

<?php
use Illuminate\Support\Facades\Product;
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateProductsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('product', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->timestamps();
            $table->string('imagePath');
            $table->string('title');  
            $table->text('description');
            $table->integer('price');    
        });
    }

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

这就是cmd返回的内容 cmd 由于我无法再发布90分钟，并且我需要相对快地解决此问题，因此我将对此帖子进行编辑。

Answer 1

名称空间区分大小写\app\Product应该为\App\Product

也可能有用的是使用命令composer dumpautoload

Answer 2

您定义了错误的名称空间。将代码更改为此：

public function run()
{
    $product=new \App\Product([
        'imagepath' =>'https://cdn.djcity.com.au/wp-content/uploads/2016/07/14082413/launchkey-mini-elevated_0.jpg',
        'title' =>'Novation LaunchKey Mini mk2 MIDI',
        'description' =>'issa book',
        'price' =>'125'
    ]);
    $product ->save();
}

为什么db：seed返回的类app / Product不存在？
