Question

我正在 Laravel 创建迁移，当我运行命令php artisan migrate时，该命令会给我以下错误

重复列名'user_id'（'id'int unsigned not null auto_increment主键，'user_id'int unsigned not null，'user_id'int not null，'order_id_'int unsigned not null，'order_id'int not null ）默认字符集utf8 collate utf8_unicode_ci）

这是我的迁移：

<?php

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

class CreateUserOrrderTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
         Schema::create('user_orrder', function (Blueprint $table) {

            $table->increments('id');

            $table->integer('user_id')->unsigned();
            $table->integer('user_id')->references('id')->on('users');

            $table->integer('order_id')->unsigned();
            $table->integer('order_id')->references('id')->on('orders');
        });
    }

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

您的代码应为：

$table->foreign('user_id')->references('id')->on('users');

而不是$table->integer('user_id')->references('id')->on('users');
