Doctrine ORM integration for the Codeigniter framework

View source code on Github

Credo is a special library that easily integrates Doctrine ORM into the Codeigniter framework. It is also based on Doctrine's official integration for Codeigniter.

Installation

Install Credo through Composer:

$ composer require rougin/credo

Basic Usage

// application/models/User.php

/**
 * @Entity
 * @Table(name="user")
 */
class User extends CI_Model
{
    /**
     * @Id @GeneratedValue
     * @Column(name="id", type="integer", length=10, nullable=FALSE, unique=FALSE)
     * @var integer
     */
    protected $_id;

    // ...
}

// application/controllers/Welcome.php

$this->load->model('user');

$this->load->database();

$credo = new Rougin\Credo\Credo($this->db);

$repository = $credo->get_repository('User');

$user = $repository->findBy(array());

Using Rougin\Credo\Repository

Extend Rougin\Credo\Loader to MY_Loader:

// application/core/MY_Loader.php

class MY_Loader extends \Rougin\Credo\Loader
{
}

Kindly also use the suffix _repository for creating repositories. (e.g. User_repository)

// application/repositories/User_repository.php

use Rougin\Credo\Repository;

class User_repository extends Repository
{
    public function find_by_something()
    {
        // ...
    }
}

Then load the repository using $this->load->repository($repositoryName).

// application/controllers/Welcome.php

$this->load->model('user');

// Loads the customized repository
$this->load->repository('user');

$this->load->database();

$credo = new Rougin\Credo\Credo($this->db);

$repository = $credo->get_repository('User');

$users = $repository->find_by_something();

For more information about repositories in Doctrine, please check its documentation.

Using Rougin\Credo\Model

// application/models/User.php

/**
 * @Entity
 * @Table(name="user")
 */
class User extends \Rougin\Credo\Model
{
    /**
     * @Id @GeneratedValue
     * @Column(name="id", type="integer", length=10, nullable=FALSE, unique=FALSE)
     * @var integer
     */
    protected $_id;

    // ...
}

// application/controllers/Welcome.php

$this->load->model('user', '', TRUE);

$this->user->credo(new Rougin\Credo\Credo($this->db));

$users = $this->user->get();

Migrating to the v0.5.0 release

The new release for v0.5.0 will be having a backward compatibility break (BC break). So some functionalities on the earlier versions might not be working after updating. This was done to increase the maintainability of the project while also adhering to the functionalities for both Codeigniter and Doctrine ORM. To check the documentation for the last release (v0.4.0), kindly click here.

Change the CodeigniterModel class to Model class

Before

class User extends \Rougin\Credo\CodeigniterModel {}

After

class User extends \Rougin\Credo\Model {}

Change the EntityRepository class to Repository class

Before

class User extends \Rougin\Credo\EntityRepository {}

After

class User extends \Rougin\Credo\Repository {}

Set Credo instance manually to Model

Before

$this->load->model('user');

After

$this->load->model('user');

$credo = new Rougin\Credo\Credo($this->db);

$this->user->credo($credo);

All Credo functionalities are now moved to CredoTrait which is can be added on existing models.

Change the arguments for PaginateTrait::paginate

Before

// PaginateTrait::paginate($perPage, $config = array())
list($result, $links) = $this->user->paginate(5, $config);

After

$total = $this->db->count_all_results('users');

// PaginateTrait::paginate($perPage, $total, $config = array())
list($offset, $links) = $this->user->paginate(5, $total, $config);

The total count must be passed in the second parameter.

Remove Model::countAll

Before

$total = $this->user->countAll();

After

$total = $this->db->count_all_results('users');

This is being used only in PaginateTrait::paginate.

Change the method ValidateTrait::validationErrors to ValidateTrait::errors

Before

ValidateTrait::validationErrors()

After

ValidateTrait::errors()

Change the property ValidateTrait::validation_rules to ValidateTrait::rules

Before

// application/models/User.php

protected $validation_rules = array();

After

// application/models/User.php

protected $rules = array();

Change the method Model::all to Model::get

Before

$users = $this->user->all();

After

$users = $this->user->get();
