php artisan migrate:fresh --seed 不能将表种入MySQL中

问题描述 投票:0回答:1

我刚刚开始学习PHP和Laravel 7,之前没有任何经验。我想我和Artisan之间有一些信任的问题, 我不知道为什么. :) 我到了播种步骤, 我面临一个错误, 我需要你的专业知识来解决. 以下是我在面临这个问题之前的步骤。

我创建产品控制器&模型

php artisan make:model Product -m -c -resource

数据库

class CreateProductsTable extends Migration
{
    public function up()
    {
        Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->string('name', 100);
            $table->string('image')->nullable();
            $table->string('type');
            $table->decimal('price', 2);
            $table->text('description')->nullable();
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('products');
    }
}

型号

class Product extends Model
{
    protected $table = 'product';
    protected $fillable = ['name', 'image', 'type', 'price', 'description'];
}

控制器

class ProductController extends Controller
{

    public function __construct()
    {
       $this->middleware('auth');
    }

    public function index()
    {
        $product = DB::table('products')->get();
    }
}

AppServiceProvider

class AppServiceProvider extends ServiceProvider
{
    public function register()
    {
        Schema::defaultStringLength(191);
    }
}

之后,我创建了 产品表播种机

php artisan make:播种机 ProductTableSeeder

class ProductTableSeeder extends Seeder
{
    public function run()
    {
        Product::insert([
            'name' => 'iphone',
            'type' => 'smart phone',
            'price' => 1000.98,
            'description' => 'Cillum sint dolore sint labori',
        ]);

        Product::insert([
            'name' => 'Galaxy',
            'type' => 'tablets',
            'price' => 2000.50,
            'description' => 'Cillum sint dolore sint labori',
        ]);

        Product::insert([
            'name' => 'Sony',
            'type' => 'TV',
            'price' => 3000,
            'description' => 'Cillum sint dolore sint labori',
        ]);
    }
}

那时,叫播种机

class DatabaseSeeder extends Seeder
{
    public function run()
    {
        // $this->call(UserSeeder::class);
        $this->call(ProductTableSeeder::class);
    }
}

那么 composer dump-autoload

最后,在输入播种命令

php artisan migrate:fresh --seed

我一直得到以下错误。

@KHA你要么把 $table

属性,或像修改

protected $table = 'products';

帮我解决了这个问题,下面是解决方案。

在模型中,我在表名的末尾添加's'(忘了把它变成复数)。

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $table = 'products'; //(forgot to make it plural)

    protected $fillable = ['name','image','type','price','description',
                          ];
}

控制器。

<?php

namespace App\Http\Controllers;

use App\Product;
use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;

class ProductController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
       //$this->middleware('auth');
    }

    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
         $prod = Product::paginate(20);
         return view('allproducts');

    // $products = [0=>['name'=>'iphone','category'=>'smart phone', 'price'=>1000,],
    //              1=>['name'=>'Galaxy','category'=>'tablets', 'price'=>2000],
    //              2=>['name'=>'Sony','category'=>'TV', 'price'=>3000]];
    // return $products;

     //return view('allproducts',compact('product'));
}

把价格的变量从十进制改为双数

public function up()
{
    Schema::create('products', function (Blueprint $table) {
        $table->id();

        $table->string('name', 100);
        $table->string('image')->nullable();
        $table->string('type');
        $table->double('price', 2);//change the variable
        $table->text('description')->nullable();

        $table->timestamps();
    });
}

然后运行命令

php artisan migrate:refresh --seed
