DEPRECATED

This package is deprecated and will no longer be maintained, I recommend using Factory Muffin instead

Fakable

Allows the creation and seeding of fake Eloquent models. This is a PHP 5.4+ package.

Can be used in tests or to generate batch of fake entries in the seeds.

Installation

$ composer require anahkiasen/fakable:dev-master

Usage

Basic usage

Simply add the trait to a model like this :

use Fakable\FakableModel;

class MyModel extends Eloquent
{
  use FakableModel;
}

A lot of defaults are built-in to configure what gets assigned to what attribute, but you can override or add to this by modifing the $fakable property on your model :

class User extends Eloquent
{
  /**
   * The fakable attributes
   *
   * @var array
   */
  protected $fakables = array(
    'nationality' => 'countryCode',
    'timzeone'    => ['numberBetween', [1, 415]],
  );
}

Fakable uses Faker underneath so you can call any of Faker's methods by either simply passing a method name, or an array of ['method', [argument, argument]] as seen above.

From then on you can call multiple methods on the model to generate fake instances :

> User::fake()->toArray();
array(
  'id'          => 28,
  'name'        => 'Tempore ipsa aut dolorum sit quod.',
  'slug'        => 'tempore-ipsa-aut-dolorum-sit-quod',
  'age'         => 23,
  'biography'   => 'Culpa debitis dolorem quidem eius. Quis et voluptatibus est. Quia nulla rerum expedita magnam.',
  'email'       => '[email protected]',
  'website'     => 'http://www.weissnat.com/',
  'address'     => '91274 Schmitt Light Suite 378',
  'country'     => 'Sudan',
  'city'        => 'North Twila',
  'private'     => false,
  'nationality' => 'RU'
)

You can also generate multiple models by calling fakeMultiple(attributes, min, max) :

User::fakeMultiple(array(
  'name' => 'foobar',
), 5, 10);

User::count() // 7

Advanced usage

To get more control over the flow of your generated fake models you can do this :

User::fakable()

This will return a Fakable instance from which you can set various options :

User::fakable()
  ->setPool(10, 20) // Will generate 10 to 20 entries
  ->setPoolFromModel('Discussion', 2) // Will generate 2 users for every discussion
  ->setSaved(false) // Won't save anything to the database
  ->fakeModel() // Generated a single fake model, that's what ::fake() calls
  ->fakeMultiple() // Generate multiple models from the pool set previously

Setting attributes on fake models

You can also set attributes on generated fake models that may not be random :

User::fakable()->fakeMultiple(array(
  'gender' => 'Male',
));

Attributes fixtures

Instead of setting all your attributes on your models you can also create an attributes fixture to hold them all. This file can be anywhere and can be either a PHP, YAML or JSON file. You tell Fakable where to find it by setting the Fakable\Fakable::$baseFixture variable to its path, in the setup of your seeding per example, or the start of your application.

Fakable\Fakable::$baseFixture = app_path().'/tests/fixtures/fakable.yml';

You can also set a different file for a specific Fakable instance, like this per example:

User::fakable()->setFixture(__DIR__.'/fixtures/user.json')->fakeModel()

The file is a simple array [class => attributes] like this:

User:
  name: 'name'
  age: ['numberBetween', [0, 20]]

Relationships

Fakable will also seed relationships when possible. Most of the time this is a completely automatic process, you simply add the name of the relationship to the fakable attributes and pass it an empty signature :

protected $fakables = array(
  'discussions' => [],
);

Optionally you can pass a number of generated relations to generate by passing a min and/or max :

protected $fakables = array(
  'discussions' => [10, 20],
);

Do note, this currently doesn't work for Has-type relations : Fakable can only seed from the point of the receiver (ie Belongs-type relations).

The only relation you really need to configure are morphTo relations because, well, it's a pain to guess their behavior :

class Image extends Eloquent
{
  protected $fakables = array(
    'illustrable' => [
      'relationType' => 'MorphTo',
      'forModels'    => ['User', 'Discussion']
    ],
  );
}

Here, relationType will tell Fakable this is a MorphTo relationship, and forModels will indicate it what kind of models Image may be a polymorphic relation of.

By default Fakable will use the attribute name as the foreign key (so illustrable would look for illustrable_type and illustrable_id) but you can also pass a foreignKey to the signature to specify that :

class Image extends Eloquent
{
  protected $fakables = array(
    'illustrable' => [
      'foreignKey'   => 'imageable',
      'relationType' => 'MorphTo',
      'forModels'    => ['User', 'Discussion']
    ],
  );
}
