Php Laravel 4数据库种子不'；行不通

我将遵循以下教程：

本教程：

但是，当我尝试运行php artisan db:seed时，什么都没有发生

我试试这个：

<?php
    // app/database/seeds/groups.php
    return array(
        'table' => 'groups',
        array(
            'name' => 'Administrador',
            'description' => '<p>Permissão total no sistema</p>',
            'created_at' => new DateTime,   
            'updated_at' => new DateTime
        ),
        array(
            'name' => 'Moderadores',
            'description' => '<p>Podem apenas postar e moderar comentários</p>',
            'created_at' => new DateTime,   
            'updated_at' => new DateTime
        )
    );

但是：

---

本教程中的示例是错误的-因为种子在Beta 1和Beta 2之间的工作方式发生了变化

将您的

DatabaseSeeder.php

文件更改为以下格式-它将适用于本教程：

<?php

class DatabaseSeeder extends Seeder {

    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $this->call('UserTableSeeder');
    }

}

class UserTableSeeder extends Seeder {

    public function run()
    {
        DB::table('users')->delete();
        User::create(array(
                'id' => 1,
                'username' => 'firstuser',
                'password' => Hash::make('first_password'),
                'created_at' => new DateTime,
                'updated_at' => new DateTime
        ));
        User::create(array(
                'id' => 2,
                'username' => 'seconduser',
                'password' => Hash::make('second_password'),
                'created_at' => new DateTime,
                'updated_at' => new DateTime
        ));    
    }
}

如果@Shift Exchange返回一些错误，如“未找到类用户”，您可以尝试

DB::table('users')->insert(array(...)) 

// DatabaseSeeder.php
class DatabaseSeeder extends Seeder {

    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        ...
        $this->call('NoticesTableSeeder');
        $this->command->info('Notices table seeded!');
        ...
    }

}

而不是

User::create(array(...))

创建您的播种机：

<?php

// NoticesTableSeeder.php    
class NoticesTableSeeder extends Seeder {

    public function run()
    {
        DB::table('notices')->truncate();

        $notices = [
            ['title' => 'Our Web Page Is Back Online!', 'body' => 'Our web site is online again. Thanks for visiting.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 1', 'body' => 'Sample new notice content.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 2', 'body' => 'Sample new notice content.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 3', 'body' => 'Sample new notice content.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 4', 'body' => 'Sample new notice content.', 'created_at' => new DateTime]
        ];
        DB::table('notices')->insert($notices);
    }

}

// DatabaseSeeder.php
class DatabaseSeeder extends Seeder {

    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        ...
        $this->call('NoticesTableSeeder');
        $this->command->info('Notices table seeded!');
        ...
    }

}

composer dump-autoload

php artisan db:seed

更换自动加载器：

<?php

// NoticesTableSeeder.php    
class NoticesTableSeeder extends Seeder {

    public function run()
    {
        DB::table('notices')->truncate();

        $notices = [
            ['title' => 'Our Web Page Is Back Online!', 'body' => 'Our web site is online again. Thanks for visiting.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 1', 'body' => 'Sample new notice content.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 2', 'body' => 'Sample new notice content.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 3', 'body' => 'Sample new notice content.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 4', 'body' => 'Sample new notice content.', 'created_at' => new DateTime]
        ];
        DB::table('notices')->insert($notices);
    }

}

// DatabaseSeeder.php
class DatabaseSeeder extends Seeder {

    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        ...
        $this->call('NoticesTableSeeder');
        $this->command->info('Notices table seeded!');
        ...
    }

}

composer dump-autoload

php artisan db:seed

为数据库设置种子：

<?php

// NoticesTableSeeder.php    
class NoticesTableSeeder extends Seeder {

    public function run()
    {
        DB::table('notices')->truncate();

        $notices = [
            ['title' => 'Our Web Page Is Back Online!', 'body' => 'Our web site is online again. Thanks for visiting.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 1', 'body' => 'Sample new notice content.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 2', 'body' => 'Sample new notice content.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 3', 'body' => 'Sample new notice content.', 'created_at' => new DateTime],
            ['title' => 'Sample New Notice 4', 'body' => 'Sample new notice content.', 'created_at' => new DateTime]
        ];
        DB::table('notices')->insert($notices);
    }

}

// DatabaseSeeder.php
class DatabaseSeeder extends Seeder {

    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        ...
        $this->call('NoticesTableSeeder');
        $this->command->info('Notices table seeded!');
        ...
    }

}

composer dump-autoload

php artisan db:seed

太好了，你完了
我将测试并给出您的反馈，请稍等。行
DB:：table（'users'）->delete（）是否不受欢迎有没有一种方法可以像迁移文件一样在databaseseeder文件之外填充它？我已经测试了几种方法，但没有一种有效。它只有在我填充databaseseeder.php文件中的数据时才起作用
// DatabaseSeeder.php
class DatabaseSeeder extends Seeder {

    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        ...
        $this->call('NoticesTableSeeder');
        $this->command->info('Notices table seeded!');
        ...
    }

}
