<?php

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

class UpdateRelationshipsForEmployee extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        //
        Schema::table('employee',function ($table){
            $table->integer('retail_id')->unsigned()->index()->change();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::table('employee', function ($table){
            $table->integer('retail_id')->change();
        });
        //

    }
}

Answer 1

只需删除整个数据库并运行命令 php artisan migrate:refresh --seed

您还可以维护您的数据库。 只需复制您的模型和迁移信息。 然后删除。 删除后重新创建模型和表。

现在。转到您的数据库迁移表。删除员工行。 现在。删除您的员工表。

现在只需终端命令 php artisan migrate

Answer 2

检查您的操作系统语言环境或 php 语言环境，

无法在 laravel 使用的依赖库中正确转换大写，因为您的语言环境与 en_us.UTF8 不同

试试

setlocale(LC_CTYPE, 'en_US.UTF8');

使用 en_us.UTF8 进行大小写转换，无论活动区域设置如何。
