Laravel5.1 Framework ModelFactory Usage Example Analysis

This article describes the usage of ModelFactory in Laravel5.1 framework model factory. Share it for your reference, as follows:

Today I want to talk about the model factory, which can quickly generate some test data. We have introduced Seeder before. When we use the model to access data, we can use the model factory with Seeder.

1 Write a ModelFactory

The path to ModelFactory is under database/factories/:

// This is the factory that comes with the system$factory->define(App\User::class, function ($faker) {
  return [
    'name' => $faker->name,
    'email' => $faker->email,
    'password' => str_random(10),
    'remember_token' => str_random(10),
  ];
});

// This is the factory we wrote$factory->define(App\Article::class, function (Faker\Generator $faker) {
  return [
    'title' => $faker->sentence,
    'body' => $faker->paragraph,
    'comment_count' => rand(1,50),
  ];
});

2 Use in seeder

After writing the model factory, you can use it in the seeder:

class ArticlesSeeder extends Seeder
{
  /**
   * Run the database seeds.
   *
   * @return void
   */
  public function run()
  {
    factory(\App\Article::class, 10)->create();
  }
}

class DatabaseSeeder extends Seeder
{
  /**
   * Run the database seeds.
   *
   * @return void
   */
  public function run()
  {
    Model::unguard();
    $this->call('ArticlesSeeder');
    Model::reguard();
  }
}
