        public function run() {

          DB::table( 'contacts' )->truncate();

          $faker = Faker::create();

          $contacts = [];

          foreach ( range( 1, 20 ) as $index ) {

            $contacts[] = [
              'name'       => $faker->name,

              'company'    => $faker->company,
              'created_at' => new DateTime,
              'updated_at' => new DateTime,
            ];
          }

          DB::table( 'contacts' )->insert( $contacts );
        }
    }

and also my DatabaseSeeder class:

    <?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);
        }
    }

please help me to solve it.

Thanks.

Answer 1

When setting this up to test, I noticed that there's a syntax error:

DB:table('contacts')->insert($contacts);

There should be two :: when calling DB::table there. This may be a copy/paste to SO error, but I think it's the cause of the problem. I added the correct :: and my seeders (which i copy/pasted from you) ran fine. I changed it to a single : and tried again, and I got the error:

[Symfony\Component\Debug\Exception\FatalErrorException]  
Call to undefined function table()

Double check that you have the correct syntax there, and it may fix your problem.

Answer 3

You need to use DB class before using. Add this fully qualified namespace:

use Illuminate\Support\Facades\DB;

to all your files wherever you use DB

Answer 4

You have to import DB:

use DB;

Or add the slash

\DB::table(...)

Answer 5

use Illuminate\Support\Facades\DB;

在行动中： DB::table('')
