Laravel 4迁移-找不到类 [英] Laravel 4 migrations - class not found
问题描述
此问题现已解决-我使用了以下内容:
而且，由于有了IRC，问题得以解决.我被告知要跑步
And, problem solved thanks to IRC. I was told to run
php composer.phar dump-autoload
这为我解决了问题.这可能与我奇怪的Composer设置有关.
This fixes the problem for me. It's likely related to my strange Composer setup.
从Laravel 3开始，我刚刚开始与Laravel 4一起玩一个未来的项目.我开始使用工匠创建了一个新的迁移create_blogs_table:
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:
php artisan migrate:make create_blogs_table --table=blogs --create
这生成了基本的迁移文件结构，然后我又填写了一些内容:
This generated the basic migration file structure which I then filled out a little more:
<?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artisan运行此迁移:
I now try to run this migration using artisan once again:
php artisan migrate --env=local
*请注意，我为具有.dev扩展名的域建立了本地数据库连接
*note I have a local database connection set up for domains with the .dev extension
以前，这可以很好地工作(在Laravel 3中)，但是使用Illuminate时，我会收到此错误:
Previously this would work just fine (in Laravel 3) but with Illuminate I then receive this error:

我已经检查过了，数据库/migrations/文件夹肯定正在自动加载.我不知道造成这个问题的原因是什么.在IRC上询问并通过Google搜索后，我还是一无所知，希望有人可以在这里为我提供帮助.
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.
提前谢谢！
推荐答案
在Laravel 4中(照亮)迁移类不需要您设置未签名的方法.你可以试试看.
In Laravel 4 (illuminate) migration class do not require you to set unsigned method. You can try this.
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');
}
}
与您聊天之后，我知道了两个问题，一个是上面已经提到的问题，另一个是由于该类未注册到作曲家自动加载中.您将必须手动运行:php composer.phar dump-autoload
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
