Laravel 4迁移 - 没有找到类

Question

这个问题现在解决了 - 我使用了以下内容:

并且,IRC解决了问题.有人告诉我跑

php composer.phar dump-autoload

这解决了我的问题.这可能与我奇怪的Composer设置有关.

---

我刚刚开始使用Laravel 4进行未来可能的项目,来自Laravel 3.我开始创建一个新的迁移,使用artisan创建create_blogs_table:

php artisan migrate:make create_blogs_table --table=blogs --create

这生成了基本的迁移文件结构,然后我填写了一些:

<?php

use Illuminate\Database\Migrations\Migration;

class CreateBlogsTable extends Migration
{

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('blogs', function($table)
        {
            $table->increments('id');
            $table->string('title');
            $table->text('description')->nullable();
            $table->integer('user_id')->unsigned();
            $table->timestamps();
        });
    }

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

我现在尝试再次使用工匠运行此迁移:

php artisan migrate --env=local

*注意我为扩展名为.dev的域设置了本地数据库连接

以前这可以正常工作(在Laravel 3中)但是使用Illuminate我会收到此错误:

我已经检查过,数据库/迁移/文件夹肯定是自动加载的.我不知道这个问题的原因是什么.在询问IRC并用Google搜索后,我仍然完全无能为力,所以希望有人可以帮助我.

提前致谢!

Answer 1

我在xubuntu上有这个错误并用sudo composer dump-autoload修复它

Answer 2

在Laravel 4(照亮)中,迁移类不需要您设置无符号方法.你可以试试这个.

  class CreateBlogsTable extends Migration
{

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('blogs', function($table)
        {
            $table->increments('id');
            $table->string('title');
            $table->text('description')->nullable();
            $table->integer('user_id');
            $table->timestamps();
        });
    }

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

在与你聊天之后,我知道了两个问题,一个是上面已经提到的问题,另一个问题是由于这个类没有注册到composer autoload中.你必须手动运行:php composer.phar dump-autoload

Answer 3

工匠做同样的工作:

php artisan dump-autoload

只是提醒那些不熟悉的人composer.
