Question

我想运行迁移以将设施列添加到我的图像表中，但它会带来此错误

这是移民文件

<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class AddFacilitiesToImagesNewTable extends Migration
{
/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::table('images_new', function (Blueprint $table) {
        $table->string('facilities');
    });
}
/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::table('images_new', function (Blueprint $table) {
        $table->dropColumn('facilities');
    });
}
}

请问导致错误的是什么

Answer 1

按照这种思路，Class AddFacilitiesToImagesNew无法解决。

在错误回溯中，打印了一个从文件名确定类名的行。

$class = Str::studly(implode('_', array_slice(explode('_', $file), 4)));

严格来说，您的类必须在迁移文件中命名为AddFacilitiesToImagesNew。

检查2018_05_26_085447_add_facilities_to_images_new.php中的迁移类是否正确命名为AddFacilitiesToImagesNew。

编辑：还有一件事，迁移无需命名空间。如果这个因为某种原因需要，请确保它已添加到您的作曲家并且您确实转储了自动加载文件。

Laravel - 运行迁移时未找到类
