Data filling in laravel framework

In order to make it easier to fill in data into the database, Laravel specifically defines a filling class that can fill in test data for your database. All filling classes are placed in the database/seeds directory. Next, this article will take you to take a look.

1. Write Seeders and fill in data

• ##Use Artisan command make:seeder to generate Seeder
  

php artisan make:seeder UserSeeder

Copy after login

• Generate UserSeeder class

<?php
namespace Database\Seeders;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;
class UserSeeder extends Seeder
{
    public function run()
    {
        
    }
}

Copy after login

• Use the query constructor in Insert data into the run method

DB::table('users')->insert(
  [
  
   ['name' => '321250887','email' => '321250887@qq.com','password' => bcrypt('321250887')],
   ['name' => '321250888','email' => '321250888@qq.com','password' => bcrypt('321250888')],
   ['name' => '321250889','email' => '321250889@qq.com','password' => bcrypt('321250889')],
   ['name' => '3212508810','email' => '3212508810@qq.com','password' => bcrypt('3212508810')],
   ['name' => '3212508811','email' => '3212508811@qq.com','password' => bcrypt('3212508811')],
   ['name' => '3212508812','email' => '3212508812@qq.com','password' => bcrypt('3212508812')],
   ['name' => '3212508813','email' => '3212508813@qq.com','password' => bcrypt('3212508813')],
   ['name' => '3212508814','email' => '3212508814@qq.com','password' => bcrypt('3212508814')],
  ]);
//相应的类已经在上方导入

Copy after login

• Use the Artisan command db:seed --class option to specify a specific seeder class:

php artisan db:seed --class=UserSeeder

Copy after login

2. Use the default DatabaseSeeder class and fill in the data

• Use the query constructor to insert data in the run method

<?php
namespace Database\Seeders;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;
class DatabaseSeeder extends Seeder
{
    public function run()
    {
        DB::table(&#39;users&#39;)->insert([
            &#39;name&#39; => &#39;3212508814&#39;,
            &#39;password&#39; => bcrypt(&#39;3212508814&#39;)],
        ]);
    }
}

Copy after login

• Use the call method to run other seed classes

public function run()
{
    $this->call([
        UserSeeder::class,
        CategorySeeder::class,
    ]);
}

Copy after login

• Use Artisan command db :seed to fill the database

php artisan db:seed

Copy after login
