Laravel 4 database seed doesn't work
提问by Patrick Maciel
I follow this tutorial: http://fideloper.com/post/41750468389/laravel-4-uber-quick-start-with-auth-guide?utm_source=nettuts&utm_medium=article&utm_content=api&utm_campaign=guest_author
我遵循本教程：http: //fideloper.com/post/41750468389/laravel-4-uber-quick-start-with-auth-guide?utm_source=nettuts&utm_medium=article&utm_content=api&utm_campaign=guest_author
And this tutorial: http://laravelbook.com/laravel-database-seeding/
而本教程：http: //laravelbook.com/laravel-database-seeding/
But, when I try run php artisan db:seed, nothing happens.
但是，当我尝试 run 时php artisan db:seed，没有任何反应。
I try this:
我试试这个：
<?php
// app/database/seeds/groups.php
return array(
'table' => 'groups',
array(
'name' => 'Administrador',
'description' => '<p>Permiss?o 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
)
);
And next: php artisan db:seed.
接下来：php artisan db:seed。
php artisan db:seed --env=local
Database seeded!
But:
但：
mysql> select * from groups;
Empty set (0.00 sec)

The example in the tutorial is wrong - because there was a change to the way seeds work between Beta 1 and Beta 2.
教程中的示例是错误的 - 因为 Beta 1 和 Beta 2 之间的种子工作方式发生了变化。
Change your DatabaseSeeder.phpfile to this - and it will work for the tutorial:
将您的DatabaseSeeder.php文件更改为此 - 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
));
}
}
Now run php artisan db:seed- and it will work.
现在运行php artisan db:seed- 它会起作用。

If @The Shift Exchange return some error like "Class User not found"you could try
如果@The Shift Exchange 返回诸如“未找到类用户”之类的错误，您可以尝试
DB::table('users')->insert(array(...))
instead of
代替
User::create(array(...))

Create your seeder:
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);
}
}
Add it to the DatabaseSeeder.php
将它添加到 DatabaseSeeder.php
// DatabaseSeeder.php
class DatabaseSeeder extends Seeder {
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
...
$this->call('NoticesTableSeeder');
$this->command->info('Notices table seeded!');
...
}
}
Renew your autoloader:
更新您的自动加载器：
composer dump-autoload
Seed the database:
种子数据库：
php artisan db:seed
Great, you are done!
太好了，你完成了！
