Laravel seeder gives error. Class not found
提问by samhu kiklsk
I'm a newbie in Laravel and and I'm teaching myself how to authenticate from a login table. I have migrated and created the table. Now, I'm trying to seed the data into the login table, but the command prompt is continuously giving me error, which says Fatal Error, class login not foundand I have no idea what i have missed. So can anyone please help me. Here is the code that i have, and yes I'm using Laravel 4.3
我是 Laravel 的新手，我正在自学如何从登录表进行身份验证。我已经迁移并创建了表。现在，我正在尝试将数据播种到登录表中，但命令提示符不断给我错误，这说明Fatal Error, class login not found我不知道我错过了什么。所以任何人都可以请帮助我。这是我拥有的代码，是的，我使用的是 Laravel 4.3
<?php
class loginTableSeeder extends Seeder
{
public function run()
{
DB::table('login')->delete();
login::create(array(
'username' => 'sanju',
'password' => Hash::make('sanju')
));
}
}
?>

You need to create an Eloquent model for that table in order to use Login::create(). You can do that with a simple artisan command:
您需要为该表创建一个 Eloquent 模型才能使用Login::create(). 你可以用一个简单的 artisan 命令来做到这一点：
$ php artisan generate:model Login
$ php artisan generate:model Login
This will generate a new Eloquent model in app/modelsdirectory which should look like this.
这将在app/models目录中生成一个新的 Eloquent 模型，它应该如下所示。
class Login extends Eloquent {
protected $fillable = [];
protected $table = 'login';
}
Your code should work after that. If it still doesn't make sure you run composer dump-autoload.
您的代码应该在那之后工作。如果它仍然不能确保您运行composer dump-autoload.

Now I see, the problem is with your loginclass (with earlier question formatting the exact error was illegible). You should look again what's the name of file where you have loginclass and what's the name of class. The convention is that the file should have name Login.php(with capital letter) and the name of class also should be Login(with capital letter). You should also check in what namespace is your Loginclass. If it is defined in in Appnamespace, you should add to your LoginTableSeeder:
现在我明白了，问题出在你的login班级上（前面的问题格式化了确切的错误是难以辨认的）。您应该再次查看您拥有login类的文件的名称是什么以及类的名称是什么。约定是文件应该有名字Login.php（大写字母），类的名字也应该是Login（大写字母）。您还应该检查您的Login类是什么命名空间。如果它在App命名空间中定义，您应该添加到您的LoginTableSeeder：
use App\Login;
in the next line after <?php
在下一行之后 <?php
so basically the beginning of your file should look like this:
所以基本上你的文件的开头应该是这样的：
<?php
use App\Login;
use Illuminate\Database\Seeder;
EARLIER ANSWER
较早的回答
You didn't explained what the exact error is (probably the error is for Seederclass) but:
您没有解释确切的错误是什么（可能是Seeder类的错误）但是：
In database/seeds/DatabaseSeeder.phpyou should run Login seeder like this:
在database/seeds/DatabaseSeeder.php你应该像这样运行登录播种机：
$this->call('LoginTableSeeder');
You should put into database/seedsfile LoginTableSeeder.phpwith capital letter at the beginning.
您应该以大写字母开头database/seeds归档LoginTableSeeder.php。
Now, your file LoginTableSeeder.phpfile should look like this:
现在，您的文件LoginTableSeeder.php文件应如下所示：
<?php
use Illuminate\Database\Seeder;
class LoginTableSeeder extends Seeder
{
public function run()
{
// your code goes here
}
}
you need to import Seederwith useat the beginning of file and again class name should start with capital letter.
你需要在文件的开头导入Seeder，use并且类名应该以大写字母开头。
Now you should run composer dump-autoloadand now when you run php artisan db:seedit will work fine.
现在你应该运行composer dump-autoload，现在当你运行php artisan db:seed它会正常工作。

Just run
composer dump-autoload -ofor the autoloader to pick up the newly classes because the database folder is not automatically autoloaded with PSR-4.
只需运行
composer dump-autoload -o自动加载器以获取新类，因为数据库文件夹不会自动使用 PSR-4 自动加载。

This worked for me
这对我有用
composer dump-autoload -o

I have the same problem but you can solve it by adding your namespace:
我有同样的问题，但您可以通过添加命名空间来解决它：
namespace yournamespace;
use App\Login;
use Illuminate\Database\Seeder;

I've experienced the same problem. In my case, the composer was extremely old and after it's update everything runs Ok.
我也遇到过同样的问题。就我而言，作曲家非常老，更新后一切正常。
Update composer with the command:
使用以下命令更新作曲家：
$ composer self-update
$ composer 自我更新
Hope it can help others.
希望它可以帮助其他人。
