laravel 模拟数据 seed

1. 生成model和migration

   php artisan make:model Model/Lesson -m

   2.建表结构和模型

    public function up()

   {

    Schema::create('lessons', function (Blueprint $table) {
   
        $table->increments('id');
   
        $table->string('title');
   
        $table->text('body');
   
        $table->boolean('free');
   
        $table->timestamps();
   
    });

   }

   php artisan migrate

   3.在 database\factories\CommonFactory.php中书写

   // Lesson

$factory->define(App\Model\Lesson::class, function (Faker $faker) {

return [

    'title' => $faker->sentence,

    'body' => $faker->paragraph,

    'free' => $faker->boolean()

];

});

4.新建 database\seeds\LessonTableSeeder.php

run方法中书写

factory('App\Model\Lesson', 50)->create();

php artisan make:seeder LessonTableSeeder

5.执行

php artisan db:seed --class=LessonTableSeeder

6.同5选其1

在 database\seeds\DatabaseSeeder.php 中 run方法下新增

$this->call(LessonTableSeeder::class);

执行

php artisan db:seed
