Contribution And Tests

git clone https://github.com/bahadirbirsoz/bb-orm

I have tested with php 7.2.2 and 7.4. You can run tests in your environment.

Getting Started

Installation

composer require bahadirbirsoz/bb-orm

Configuration

$_ENV['BBORM_USERNAME'] = 'root';
$_ENV['BBORM_PASSWORD'] = 'password';
$_ENV['BBORM_DATABASE'] = 'test';
$_ENV['BBORM_HOSTNAME'] = '127.0.0.1';

Writing Your First Model

class Category extends \BbOrm\Model
{
    public $id;
    public $name;
    public $sorting;
}

• Models are supposed to be extended from \BbOrm\Model class.
• snake_case representation of PascalCaseModelName is assumed to be table name. Can be overwritten via ::getTable method.
• $id is assumed to be the primary key in each table. Can be overwritten via ::getPK method.
• Every table must have one and only one primary key.
• Composite primary keys are not supported

class Category extends \BbOrm\Model
{
    public $category_id;
    public $name;
    public $sorting;

    public static function getTable(){
        return "table_name_in_database"; 
        //by default it was category, overwritten to table_name_in_database 
    }

    public static function getPK(){
        return "category_id";
        //by default it was id, overwritten to category_id
    }
}

Access Layeres

Getter and Setters methods will be called by magic ::__get and ::__set methods if exists. Otherview will throw \BbOrm\Exceptions\AccessViolationException

class Post extends Model
{
    protected $id;
    protected $title;
    protected $url;

    public function getId()
    {
        return $this->id;
    }

    public function setTitle($title)
    {
        $this->title = $title;
        $url = preg_replace('/[^\w\-]+/u', '-', $title);
        $this->url = mb_strtolower(preg_replace('/--+/u', '-', $url), 'UTF-8');
    }

    public function getTitle()
    {
        return $this->title;
    }

    public function getUrl()
    {
        return $this->url;
    }
}

Usage

    $postObj = new Post();
    $postObj->title = "Set title will be called by magic ::__set"

Custom Event Handlers

There are custom events hooks that bind functions to custom events. Following interfaces can be implemented for event hooks.

• \BbOrm\EventHandlers\BeforeCreate
• \BbOrm\EventHandlers\BeforeUpdate
• \BbOrm\EventHandlers\BeforeSave
• \BbOrm\EventHandlers\AfterCreate
• \BbOrm\EventHandlers\AfterUpdate
• \BbOrm\EventHandlers\AfterSave

use BbOrm\EventHandlers\BeforeCreate;
use BbOrm\EventHandlers\BeforeUpdate;
use BbOrm\Model;
class Post extends Model implements BeforeCreate, BeforeUpdate
{
    public $id;
    public $created_at;
    public $updated_at;
    
    public function beforeCreate()
    {
        $this->created_at = date("Y-m-d H:i:s");
    }

    public function beforeUpdate()
    {
        $this->updated_at = date("Y-m-d H:i:s");
    }
}    

Transaction begins with entity save method gets called. If an event hook fails, transaction rollbacks implicitly.

class Tag extends Model implements AfterCreate, AfterSave, AfterUpdate, BeforeSave
{
    public $id;
    public $tag;
    public $saved_at;

    public function beforeSave()
    {
        $this->saved_at = date("Y-m-d H:i:s");
    }

    public function afterCreate()
    {
        $event = new TagEventLog();
        $event->tag_id = $this->id;
        $event->event = 'afterCreate';
        $event->save();
    }

    public function afterUpdate()
    {
        $event = new TagEventLog();
        $event->tag_id = $this->id;
        $event->event = 'afterUpdate';
        $event->save();
    }

    public function afterSave()
    {
        $event = new TagEventLog();
        $event->tag_id = $this->id;
        $event->event = 'afterSave';
        $event->save();
    }

}

Finding All Rows

public static function find($where = [], $order = [], $group = [], $limit = [], $fetchMethod = \PDO::FETCH_CLASS);

$posts = Post::find();

$posts = Post::find([
    "category_id" => $category->id
]);

$posts = Post::find([
    "conditions" => "created_at > ? AND category_id = ?",
    "bind" => [
        date('Y-m-d H:i:s' , strtotime('-7 days') ),
        $category->id
    ]
]);

Finding One Row

public static function findOne($data = [], $order = []);

$category = Category::findOne();

$category = Category::findOne([
    'category_id' => '17'
]);

$category = Category::findOneById(17);

when an integer argument is provided as first argument to find method, find method works as findOneById

$category = Category::find(17);

$lastCategory = Category::findOne([],['id desc']);

$posts = Post::find([
    "category_id" => $category->id
]);

Magic Find Methods

::findOneByPropertyName and ::findByPropertyName magic methods exists and.

$posts = Post::findByCategoryId($category->id);

$categoryId = 17; //Sanitized argument
$post = Post::findByCategoryId($categoryId);

if(!$post){
    //404, returns false if not found
}else{
    // ...
}

$url = 'parsed-url';
$post = Post::findOneByUrl($url);

if(!$post){
    //404, returns false if not found
}else{
    // ...
}

Phalcon-Style Find Calls

$posts = Post::find([
    "conditions" => "category_id = ?",
    "bind" => [
        $category->id
    ]
]);

$posts = Post::find([
    "conditions" => "created_at > ? AND category_id = ?",
    "bind" => [
        date('Y-m-d H:i:s' , strtotime('-7 days') ),
        $category->id
    ]
]);

Saving Entities

$post = new Post();
$post->title = 'title';
$post->save();

$category = Category::find();
$category->name = 'New cateogry name';
$category->save();

Deleting Rows

You can remove an entity, or call static ::delete method for custom delete queries.

$category = Category::find();
$category->name = 'New cateogry name';
$category->remove();

Post::delete([
    'category_id' => $category->id
])

Custom Queries

You can run custom queries.

$query = "select
    tag.*,
	count(distinct(post.id)) as postCount,
    count(distinct(category.id)) as categoryCount
from
    tag
left join post_tag
    on post_tag.tag_id = tag.id
left join post
    on  post.id = post_tag.post_id
left join category
    on category.id = post.category_id
";
    $items = DataRow::select($query, [], [], ['tag.id']);

You can also define query classes for representation.

Fore more information, you can read the unit tests (for now).
