Seed multiple rows at once laravel 5

问题:

I'm currently trying to seed my users table. If I try it like this with 2 rows, it fails. It works fine if I just use a single array instead of the 2 arrays inside the $users array to create some fake data.

What am I doing wrong, what is the proper way to do this?

class UserTableSeeder extends Seeder {

    public function run()
    {
        DB::table('users')->delete();

        $users = [
            ['id' => 1, 'name' => 'Stephan de Vries', 'username' => 'stephan', 'email' => '[e-mail]', 'password' => bcrypt('carrotz124')],
            ['id' => 2, 'name' => 'John doe', 'username' => 'johnny', 'email' => '[e-mail]', 'password' => bcrypt('carrotz1243')],
        ];

        User::create($users);
    }

}

回答1:

If you have to use the model you need a loop:

foreach($users as $user){
    User::create($user);
}

Otherwise you can just use DB::table() and insert:

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

Actually you can also call insert() on the model (the resulting query is the same)

User::insert($users);

Note if you choose the insert method you loose special Eloquent functionality such as timestamps and model events.

This works, even for Laravel 5.3

<?php

use Illuminate\Database\Seeder;

class UsersTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */

    public function run()
    {
        // check if table users is empty
        if(DB::table('users')->get()->count() == 0){

            DB::table('users')->insert([

                [
                    'name' => 'Administrator',
                    'email' => '[e-mail]',
                    'password' => bcrypt('password'),
                    'created_at' => date('Y-m-d H:i:s'),
                    'updated_at' => date('Y-m-d H:i:s'),
                ],
                [
                    'name' => 'Agency',
                    'email' => '[e-mail]',
                    'password' => bcrypt('password'),
                    'created_at' => date('Y-m-d H:i:s'),
                    'updated_at' => date('Y-m-d H:i:s'),
                ],
                [
                    'name' => 'End',
                    'email' => '[e-mail]',
                    'password' => bcrypt('password'),
                    'created_at' => date('Y-m-d H:i:s'),
                    'updated_at' => date('Y-m-d H:i:s'),
                ]

            ]);

        } else { echo "\e[31mTable is not empty, therefore NOT "; }

    }
}

public function run()
{
    //
    for ($i=0; $i < 1000; $i++) { 
         DB::table('seo_contents')->insert([
            'title' => str_random(10),
            'content' => str_random(100),
            'created_at'=>date('Y-m-d H:i:s'),
            'updated_at'=>date('Y-m-d H:i:s'),

        ]);
    }

}

You should use insert instead of create. So the code will look like this:

class UserTableSeeder extends Seeder {

  public function run()
  {
    DB::table('users')->delete();

    $users = [
        ['id' => 1, 'name' => 'Stephan de Vries', 'username' => 'stephan', 'email' => '[e-mail]', 'password' => bcrypt('carrotz124')],
        ['id' => 2, 'name' => 'John doe', 'username' => 'johnny', 'email' => '[e-mail]', 'password' => bcrypt('carrotz1243')],
    ];

    User::insert($users);
  }

}

If anyone is struggling with this, I have been using the following since Laravel 5 and can confirm is still working in Laravel 7+...

class UserTableSeeder extends Seeder {

public function run()
{
    \DB::table('users')->delete();

    \DB::table('users')->insert(array (
        0 => 
          array (
                 'id' => 1,
                 'name' => 'Stephan de Vries',
                 'username' => 'stephan',
                 'email' => '[e-mail]',
                 'password' => bcrypt('carrotz124'
         ),
        1 => 
          array (
                 'id' => 2,
                 'name' => 'John doe',
                 'username' => 'johnny',
                 'email' => '[e-mail]',
                 'password' => bcrypt('carrotz1243'
         ),
     ));

}}
