Question

迁移会在 Laravel 5.3 的数据透视迁移后生成异常。

schema1 : software_houses
schema2 : skill_domains

我生成了命令make:migration:pivot skill_domains software_houses

并且迁移是通过 skill_domain_software_house

的名称创建的

但是当我执行php artisan migrate

时

发生以下错误：

 [Symfony\Component\Debug\Exception\FatalThrowableError]      
 Class 'CreateSkillDomainSoftwareHousePivotTable' not found

See this Image

SKILL Domain

<?php

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

class CreateSkillDomainsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {

        Schema::create('skill_domains', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name')->unique();
            $table->timestamps();
        });


    }

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

软件公司

<?php

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

class CreateSoftwareHousesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('software_houses', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name',100)->unique();
            $table->string('desc',500);
            $table->string('url',100);
            $table->string('rating')->default('3');
            $table->string('logo')->nullable();
            $table->string('city')->nullable();

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

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

运行make：migration :: pivot命令后创建的数据透视表

<?php

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

class CreateSkill_domainSoftware_housePivotTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('skill_domain_software_house', function (Blueprint $table) {
            $table->integer('skill_domain_id')->unsigned()->index();
            $table->foreign('skill_domain_id')->references('id')->on('skill_domains')->onDelete('cascade');
            $table->integer('software_house_id')->unsigned()->index();
            $table->foreign('software_house_id')->references('id')->on('software_houses')->onDelete('cascade');
            $table->primary(['skill_domain_id', 'software_house_id']);
        });
    }

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

Answer 1

尝试使用以下类名称行： class SkillDomainsSoftwareHouses extends Migration

确保文件名应与班级名称Documentation匹配。

我想你应该试试这个：

首先删除上面的software_houses，从迁移文件夹中的skill_domains也从数据库中的迁移表中删除，然后按照以下步骤操作：

1) php artisan make:migration skilldomain
2) php artisan make:migration softwarehouses
3) php artisan make:migration:pivot skilldomains softwarehouses
4) php artisan migrate

在Laravel 5.3的数据透视迁移后迁移不起作用
