About

Library extends Laravel's Eloquent ORM with pretty full support of composite keys

Usage

Laravel 5.5

composer require maksimru/composite-primary-keys ~0.14

Laravel 5.6+

composer require maksimru/composite-primary-keys ~1.0

Simply add \MaksimM\CompositePrimaryKeys\Http\Traits\HasCompositePrimaryKey trait into required models

Features Support

• increment and decrement

• update and save query

• binary columns

  class BinaryKeyUser extends Model
  {
      use \MaksimM\CompositePrimaryKeys\Http\Traits\HasCompositePrimaryKey;
  
      protected $binaryColumns = [
          'user_id'
      ];
  
      protected $primaryKey = 'user_id';
  }

  With $hexBinaryColumns = false or omitted, $binaryKeyUser->user_id will return binary value. BinaryKeyUser::find('BINARY_VALUE') and BinaryKeyUser::create(['id' => 'BINARY_VALUE']) should be used in this case

  Optional ability to automatically encode binary values to their hex representation:

  class BinaryKeyUser extends Model
  {
    use \MaksimM\CompositePrimaryKeys\Http\Traits\HasCompositePrimaryKey;
  
    protected $binaryColumns = [
        'user_id'
    ];
  
    protected $primaryKey = 'user_id';
  
    protected $hexBinaryColumns = true;
  }

  With $hexBinaryColumns = true, $binaryKeyUser->user_id will return hex value. BinaryKeyUser::find('HEX_VALUE') and BinaryKeyUser::create(['id' => 'HEX_VALUE']) should be used in this case

  JSON output will contain hex values in both cases

• model serialization in queues (with Illuminate\Queue\SerializesModels trait)

  Job:

  class TestJob implements ShouldQueue
  {
      use Queueable, SerializesModels;
  
      private $model;
  
      /**
       * Create a new job instance.
       */
      public function __construct(TestUser $testUser)
      {
          $this->model = $testUser;
      }
  
      /**
       * Execute the job.
       */
      public function handle()
      {
          $this->model->update(['counter' => 3333]);
      }
  }

  Dispatch:

  $model = TestUser::find([
      'user_id' => 1,
      'organization_id' => 100,
  ]);
  $this->dispatch(new TestJob($model));

• route implicit model binding support

  Model:

  class TestBinaryUser extends Model
  {
      use \MaksimM\CompositePrimaryKeys\Http\Traits\HasCompositePrimaryKey;
      
      protected $table = 'binary_users';
      
      public $timestamps = false;
      
      protected $binaryColumns = [
        'user_id'
      ];
      
      protected $primaryKey = [
        'user_id',
        'organization_id',
      ];
  }

  routes.php:

  $router->get('binary-users/{binaryUser}', function (BinaryUser $binaryUser) {
      return $binaryUser->toJson();
  })->middleware('bindings')

  request:

  GET /binary-users/D9798CDF31C02D86B8B81CC119D94836___100

  response:

  {"user_id":"D9798CDF31C02D86B8B81CC119D94836","organization_id":"100","name":"Foo","user_id___organization_id":"D9798CDF31C02D86B8B81CC119D94836___100"}

• relations (only belongsTo relation is supported in this version)

  class TestUser extends Model
  {
      use \MaksimM\CompositePrimaryKeys\Http\Traits\HasCompositePrimaryKey;
  
      protected $table = 'users';
  
      protected $primaryKey = [
          'user_id',
          'organization_id',
      ];
  
      public function referrer()
      {
          return $this->belongsTo(TestUser::class, [
              'referred_by_user_id',
              'referred_by_organization_id'
          ], [
              'user_id',
              'organization_id',
          ]);
      }
  }
  
  $referrer_user = $testUser->referrer()->first();

  will call

  select * from "users" where (("user_id" = ? and "organization_id" = ?)) limit 1

  with bindings [ $testUser->referred_by_user_id, $testUser->referred_by_organization_id ]
