Laravel 8 播种时日期时间无效

Question

我是 laravel 的新手，我在尝试播种数据时收到错误，我已经在两个不同的表中成功完成了，但我被困在这个表中：型号

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Project extends Model
{
    use HasFactory;

    public $timestamps = false;

    protected $fillable = [
        'Pmid',
        'Ministry',
        'P_name',
        'Budget',
    ];

    protected $casts = [
        'Registered_at' => 'datetime',
    ];
}

工厂

<?php

namespace Database\Factories;

use App\Models\Project;
use Illuminate\Database\Eloquent\Factories\Factory;

class ProjectFactory extends Factory
{
    protected $model = Project::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'Pmid'          => $this->faker->unique()->name(),
            'Ministry'      => $this->faker->name(),
            'P_name'        => $this->faker->name(),
            'Budget'        => $this->faker->name(),
            'Registered_at' => now(),
        ];
    }
}

播种机

<?php

namespace Database\Seeders;

use App\Models\Project;
use Illuminate\Database\Seeder;

class ProjectTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Project::factory()->count(20)->create();
    }
}

迁移

<?php

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

class CreateProjectsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('projects', function (Blueprint $table) {
            $table->increments('id');
            $table->string('Pmid')->unique();
            $table->string('Ministry');
            $table->string('P_name');
            $table->integer('Budget');
            $table->timestamp('Registered_at');
        });
    }

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

错误

Illuminate\Database\QueryException SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect integer value: 'Mathias Kuhlman' for column laravel.projects.Budget at row 1 (SQL: insert into projects (Pmid, Ministry, P_name, Budget, Registered_at) values (Nicholas Mayer, Ms. Donna Strosin, Hermann Bins, Mathias Kuhlman, 2021-12-05 08:36:39))

Answer 1

您正在使用

'Budget'        => $this->faker->name(),

创建数据，但您的迁移显示该列应该是一个整数：

$table->integer('Budget');

我怀疑您只是复制并粘贴了伪造的行，而没有更改被伪造的值的类型。
