Laravel Repositories is a package for Laravel 5 which is used to abstract the database layer. This makes applications much easier to maintain.
Run the following command from you terminal:
composer require "bosnadev/repositories: 0.*"
or add this to require section in your composer.json file:
"bosnadev/repositories": "0.*"
then run composer update
First, create your repository class. Note that your repository class MUST extend Bosnadev\Repositories\Eloquent\Repository
and implement model() method
<?php namespace App\Repositories;
use Bosnadev\Repositories\Contracts\RepositoryInterface;
use Bosnadev\Repositories\Eloquent\Repository;
class FilmsRepository extends Repository {
public function model() {
return 'App\Film';
}
}
By implementing model()
method you telling repository what model class you want to use. Now, create App\Film
model:
<?php namespace App;
use Illuminate\Database\Eloquent\Model;
class Film extends Model {
protected $primaryKey = 'film_id';
protected $table = 'film';
protected $casts = [
"rental_rate" => 'float'
];
}
And finally, use the repository in the controller:
<?php namespace App\Http\Controllers;
use App\Repositories\FilmsRepository as Film;
class FilmsController extends Controller {
private $film;
public function __construct(Film $film) {
$this->film = $film;
}
public function index() {
return \Response::json($this->film->all());
}
}
The following methods are available:
public function all($columns = array('*'))
public function lists($value, $key = null)
public function paginate($perPage = 1, $columns = array('*'));
public function create(array $data)
// if you use mongodb then you'll need to specify primary key $attribute
public function update(array $data, $id, $attribute = "id")
public function delete($id)
public function find($id, $columns = array('*'))
public function findBy($field, $value, $columns = array('*'))
public function findAllBy($field, $value, $columns = array('*'))
public function findWhere($where, $columns = array('*'))
public function apply($model, Repository $repository)
Create a new film in repository:
$this->film->create(Input::all());
Update existing film:
$this->film->update(Input::all(), $film_id);
Delete film:
$this->film->delete($id);
Find film by film_id;
$this->film->find($id);
you can also chose what columns to fetch:
$this->film->find($id, ['title', 'description', 'release_date']);
Get a single row by a single column criteria.
$this->film->findBy('title', $title);
Or you can get all rows by a single column criteria.
$this->film->findAllBy('author_id', $author_id);
Get all results by multiple fields
$this->film->findWhere([
'author_id' => $author_id,
['year','>',$year]
]);
Criteria is a simple way to apply specific condition, or set of conditions to the repository query. Your criteria class MUST extend the abstract Bosnadev\Repositories\Criteria\Criteria
class.
Here is a simple criteria:
<?php namespace App\Repositories\Criteria\Films;
use Bosnadev\Repositories\Criteria\Criteria;
use Bosnadev\Repositories\Contracts\RepositoryInterface as Repository;
class LengthOverTwoHours extends Criteria {
/**
* @param $model
* @param RepositoryInterface $repository
* @return mixed
*/
public function apply($model, Repository $repository)
{
$model = $model->where('length', '>', 120);
return $model;
}
}
Now, inside you controller class you call pushCriteria method:
<?php namespace App\Http\Controllers;
use App\Repositories\Criteria\Films\LengthOverTwoHours;
use App\Repositories\FilmsRepository as Film;
class FilmsController extends Controller {
/**
* @var Film
*/
private $film;
public function __construct(Film $film) {
$this->film = $film;
}
public function index() {
$this->film->pushCriteria(new LengthOverTwoHours());
return \Response::json($this->film->all());
}
}
This package is largely inspired by this great package by @andersao. Here is another package I used as reference.
