laravel 社区 使用ModelFactory 生产测试数据 artisan 建表

php artisan make:migration create_discussions_table –create=discussions

public function up()
{
Schema::create(‘discussions’, function (Blueprint table) {table->increments(‘id’);
table−>string(‘title′); table->text(‘body’);
table−>integer(‘userid′)−>unsigned(); table->integer(‘last_user_id’)->unsigned();
table−>foreign(‘userid′)−>references(‘id′)−>on(‘users′)−>onDelete(‘cascade′); table->timestamps();
});
}

public function up()
{
Schema::create(‘users’, function (Blueprint table) {table->increments(‘id’);
table−>string(‘name′); table->string(‘avatar’); //添加头像
table−>string(‘email′)−>unique(); table->string(‘password’,60);
table−>rememberToken(); table->timestamps();
});
}

迁移表
php artisan migtate

在 User.php
protected $fillable = [‘name’, ‘email’, ‘password’,’avatar’];

在Discussion.php
protected $fillable = [‘title’, ‘body’, ‘user_id’,’last_user_id’];

在Model Factories

/*
|————————————————————————–

Model Factories
Here you may define all of your model factories. Model factories give
you a convenient way to create models for testing and seeding your
database. Just tell the factory how a default model should look.

*/

factory−>define(App\User::class,function(Faker\Generator faker) {
return [
‘name’ => faker−>name,‘email′=> faker->email,
‘avatar’ => $faker->imageUrl(256,256),
‘password’ => str_random(10),
‘remember_token’ => str_random(10),
];
});

通过使用 Laravel artisan 内建的 php artisan tinker , 我们可以很方便的看到数据库中的数据并且执行各种想要的操作。

创建30个user
D:\xampp\htdocs\laravelB\laravel>php artisan tinker
Psy Shell v0.7.2 (PHP 5.6.15 鈥?cli) by Justin Hileman

namespace App;
=> null
factory(User::class,30)->create();
得到等等 => Illuminate\Database\Eloquent\Collection {#699
all: [
App\User {#708
name: “Mrs. Cathy Gibson II”,
email: “[email protected]”,
avatar: “http://lorempixel.com/256/256/?79243“,
updated_at: “2016-08-07 13:08:29”,
created_at: “2016-08-07 13:08:29”,
id: 1,
},
App\User {#707
name: “Angela Wilderman”,
email: “[email protected]”,
avatar: “http://lorempixel.com/256/256/?12201“,
updated_at: “2016-08-07 13:08:29”,
created_at: “2016-08-07 13:08:29”,
id: 2,
},

在Model Factories
factory−>define(App\Discussion::class,function(Faker\Generator faker) {
$user_ids = \App\User::lists(‘id’)->toArray(); /获得user_id 并转为 array/
return [
‘title’ => faker−>sentence,‘body′=> faker->paragraph,
‘user_id’ => faker−>randomElement( user_ids),
‘last_user_id’ => faker−>randomElement( user_ids),
];
});
