我是laravel的新人。 我希望通过这个命令运行种子：php artisan db：seed，我收到此错误：
[Symfony \ Component \ Debug \ Exception \ FatalThrowableError]调用 未定义的函数表（）
我的两个播种者课程：
1- GroupTableSeeder
<?php
use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
class GroupTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
DB::statement('SET FOREIGN_KEY_CHECKS=0');
DB::table('groups')->truncate();
$groups = [
['id' => 1, 'name' => 'Family', 'created_at' => new DateTime, 'updated_at' => new DateTime ],
['id' => 2, 'name' => 'Friends', 'created_at' => new DateTime, 'updated_at' => new DateTime ],
['id' => 3, 'name' => 'Customers', 'created_at' => new DateTime, 'updated_at' => new DateTime ],
['id' => 4, 'name' => 'CoWorkers', 'created_at' => new DateTime, 'updated_at' => new DateTime ],
['id' => 5, 'name' => 'Teachers', 'created_at' => new DateTime, 'updated_at' => new DateTime ]
];
DB:table('groups')->insert($groups);
}
}
2- ContactsTableSeeder
<?php
use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
use Faker\Factory as Faker;
class ContactsTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run() {
DB::table( 'contacts' )->truncate();
$faker = Faker::create();
$contacts = [];
foreach ( range( 1, 20 ) as $index ) {
$contacts[] = [
'name' => $faker->name,
'email' => $faker->email,
'phone' => $faker->phoneNumber,
'address' => "{$faker->streetName} {$faker->postcode} {$faker->city}",
'company' => $faker->company,
'created_at' => new DateTime,
'updated_at' => new DateTime,
];
}
DB::table( 'contacts' )->insert( $contacts );
}
}
以及我的DatabaseSeeder类：
<?php
use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
class DatabaseSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
$this->call(GroupTableSeeder::class);
$this->call(ContactsTableSeeder::class);
}
}
请帮我解决一下。
感谢。

将此设置为测试时，我注意到语法错误：
DB:table('contacts')->insert($contacts);
在那里调用::时应该有两个DB::table。这可能是对SO错误的复制/粘贴，但我认为这是问题的原因。我添加了正确的::和我的播种机（我复制/粘贴你）运行正常。我将其更改为单个:并再次尝试，我收到错误：
[Symfony\Component\Debug\Exception\FatalErrorException]
Call to undefined function table()
仔细检查您的语法是否正确，它可以解决您的问题。

使用前需要使用DB类。添加此完全限定的命名空间：

到您使用use Illuminate\Support\Facades\DB;

您必须导入数据库：
use DB;
或添加斜杠
\DB::table(...)
