Enjoin ORM

Getting Started

Introduction

Enjoin is an active-record ORM for PHP. Enjoin built on Laravel Components and inspired by Sequelize for Node.js. It supports MySQL and PostgreSQL dialects. Unlike Eloquent, Enjoin features eager loading, built-in validation and more.

Installation

Enjoin is available via Composer:

$ composer require mightydes/enjoin

If you need language locales, then require laravel-lang package:

$ composer require caouecs/laravel-lang

Then add Models autoload entry to your composer.json file:

  "autoload": {
    "psr-4": {
      "Models\\": [
        "app/Models"
      ]
    }
  }

Stand-alone bootstrap

<?php

require_once __DIR__ . '/vendor/autoload.php';

use Enjoin\Factory;

Factory::bootstrap([
    'database' => [
        'default' => 'acme',
        'connections' => [
            'acme' => [
                'driver' => 'mysql',
                'host' => 'localhost',
                'database' => 'acme',
                'username' => 'acme',
                'password' => 'acme',
                'charset' => 'utf8',
                'collation' => 'utf8_unicode_ci',
                'prefix' => ''
            ]
        ],
        'redis' => [
            'cluster' => false,
            'default' => [
                'host' => '127.0.0.1',
                'port' => 6379,
                'database' => 0,
            ]
        ]
    ],
    'enjoin' => [
        'lang_dir' => 'vendor/caouecs/laravel-lang'
    ],
    'cache' => [
        'default' => 'redis',
        'stores' => [
            'redis' => [
                'driver' => 'redis',
                'connection' => 'default'
            ]
        ],
        'prefix' => 'enjoin_'
    ]
]);

Laravel bootstrap

First add Enjoin\EnjoinServiceProvider to providers list, and 'Enjoin' => 'Enjoin\EnjoinFacade' to aliases list in config/app.php.

Then register config in app/Providers/ConfigServiceProvider.php:

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class ConfigServiceProvider extends ServiceProvider
{

    public function register()
    {
        config([
            'enjoin' => [
                'lang_dir' => 'vendor/caouecs/laravel-lang'
            ]
        ]);
    }

}

Model Definition

You need to define mapping between tables and models. For example, table books with columns:

id (int, primary, auto-increment)
authors_id (int, foreign-key)
title (varchar)
year (int)

Has definition:

<?php namespace Models;

use Enjoin\Model\Definition;
use Enjoin\Enjoin;

class Books extends Definition
{

    public function getAttributes()
    {
        return [
            'id' => ['type' => Enjoin::Integer()],
            'authors_id' => ['type' => Enjoin::Integer()],
            'title' => ['type' => Enjoin::String()],
            'year' => ['type' => Enjoin::Integer(), 'validate' => 'integer|max:2020']
        ];
    }

    public function getRelations()
    {
        return [
            Enjoin::belongsTo(Enjoin::get('Authors'), ['foreignKey' => 'authors_id'])
        ];
    }

}

connection

Connection to use. Equals to default connection by default. Example:

<?php namespace Models;

use Enjoin\Model\Definition;
use Enjoin\Enjoin;

class Books extends Definition
{

    public $connection = 'acme';

}

table

Table name. Equals to Inflector::tableize(<ModelClassName>) by default. Example:

<?php namespace Models;

use Enjoin\Model\Definition;
use Enjoin\Enjoin;

class Books extends Definition
{

    public $table = 'books';

}

timestamps

Enables or disables timestamps (ie created_at, updated_at). Equals to true by default. Example:

<?php namespace Models;

use Enjoin\Model\Definition;
use Enjoin\Enjoin;

class Books extends Definition
{

    public $timestamps = false;

}

createdAt

CreatedAt column name. Equals to created_at by default. Example:

<?php namespace Models;

use Enjoin\Model\Definition;
use Enjoin\Enjoin;

class Books extends Definition
{

    public $createdAt = 'createdAt';

}

updatedAt

UpdatedAt column name. Equals to updated_at by default. Example:

<?php namespace Models;

use Enjoin\Model\Definition;
use Enjoin\Enjoin;

class Books extends Definition
{

    public $updatedAt = 'updatedAt';

}

cache

Enables or disables cache. Equals to false by default. Example:

<?php namespace Models;

use Enjoin\Model\Definition;
use Enjoin\Enjoin;

class Books extends Definition
{

    public $cache = true;

}

expanseModel

Class name to extend generic model class. It is useful, if you want to define custom model methods. Example:

<?php namespace Models;

use Enjoin\Model\Definition;
use Enjoin\Enjoin;

class Books extends Definition
{

    public $expanseModel = Expanse\BooksModel::class;

}

expanseRecord

Class name to extend generic record class. It is useful, if you want to define custom record methods. Example:

<?php namespace Models;

use Enjoin\Model\Definition;
use Enjoin\Enjoin;

class Books extends Definition
{

    public $expanseRecord = Expanse\BooksRecord::class;

}

getAttributes()

Returns associative array, where each key is a table column.

getAttributes().type

Enjoin::Integer()
Enjoin::Boolean()
Enjoin::String()
Enjoin::Text()
Enjoin::Float()
Enjoin::Date()
Enjoin::Enum()

getAttributes().allowNull

Indicates is NULL allowed on field. By default is true.

getAttributes().validate

Validation rules for field. You can read more about validation here.

getAttributes().get

You can define custom getter closure for field:

    'fullname' => [
        'type' => Enjoin::String(),
        'get' => function ($attr, Closure $getValue) {
            $v = $getValue($attr);
            if (is_string($v) && strlen($v) > 0) {
                $r = explode(' ', $v);
                return [
                    'name' => $r[0],
                    'surname' => $r[1]
                ];
            }
            return null;
        }
    ]

getAttributes().set

You can define custom setter closure for field:

    'fullname' => [
        'type' => Enjoin::String(),
        'set' => function ($attr, Closure $getValue) {
            $v = $getValue($attr);
            if (is_array($v)) {
                return join(' ', $v);
            }
            return $v;
        }
    ]

getRelations()

    public function getRelations()
    {
        return [
            Enjoin::belongsTo(Enjoin::get('Authors')),
            Enjoin::belongsTo(Enjoin::get('Languages')),
            Enjoin::hasMany(Enjoin::get('Reviews')),
            Enjoin::hasMany(Enjoin::get('PublishersBooks'))
        ];
    }

getRelations().foreignKey

Foreign key column name. Example:

    public function getRelations()
    {
        return [
            Enjoin::belongsTo(Enjoin::get('Authors'), ['foreignKey' => 'authors_id'])
        ];
    }

getRelations().as

Foreign key column as alias. Example:

    public function getRelations()
    {
