Laravel 4 迁移 - 找不到类

Laravel 4 migrations - class not found

提问by Euan T

This question is now solved - I used the below:

这个问题现在解决了 - 我使用了以下内容：

And, problem solved thanks to IRC. I was told to run

并且，由于 IRC，问题解决了。我被告知要跑

php composer.phar dump-autoload

This fixes the problem for me. It's likely related to my strange Composer setup.

这为我解决了问题。这可能与我奇怪的 Composer 设置有关。

I've just started playing with Laravel 4 for a possible future project, having come from Laravel 3. I have started off by creating a new migration, create_blogs_table using artisan:

我刚开始在 Laravel 4 中使用 Laravel 4 用于未来可能的项目，来自 Laravel 3。我已经开始使用 artisan 创建一个新的迁移，create_blogs_table：

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

This generated the basic migration file structure which I then filled out a little more:

这生成了基本的迁移文件结构，然后我再填写了一点：

<?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');
    }
}

I now try to run this migration using artisan once again:

我现在尝试再次使用 artisan 运行此迁移：

php artisan migrate --env=local

*note I have a local database connection set up for domains with the .dev extension

*注意我为带有 .dev 扩展名的域设置了本地数据库连接

Previously this would work just fine (in Laravel 3) but with Illuminate I then receive this error:

以前这可以正常工作（在 Laravel 3 中）但使用 Illuminate 我然后收到此错误：

I've checked and the database/migrations/ folder is certainly being autoloaded. I have no idea what the cause for this problem may be. Having asked on IRC and googled I'm still completely clueless so hopefully somebody can help me out here.

我已经检查过，数据库/迁移/文件夹肯定正在自动加载。我不知道这个问题的原因可能是什么。在 IRC 上询问并用谷歌搜索后，我仍然完全一无所知，所以希望有人能在这里帮助我。

Thanks in advance!

提前致谢！

In Laravel 4 (illuminate) migration class do not require you to set unsigned method. You can try this.

在 Laravel 4 (illuminate) 迁移类中不需要你设置 unsigned 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');
    }
}

After having the chat with you, I knew two problems, one is that already mentioned above and the other problem is due to the class not been registered into composer autoload. You will have to run manually : php composer.phar dump-autoload

和你聊天后，我知道了两个问题，一个是上面已经提到的，另一个是因为这个类没有注册到composer autoload中。您必须手动运行：php composer.phar dump-autoload

Artisan do the same work:

工匠做同样的工作：

php artisan dump-autoload

Just a reminder for those who are not familiar with composer.

只是给不熟悉的人提个醒composer。

Update your composer (composer self-update), then run your composer functions.
