Laravel 5 Repositories is used to abstract the data layer, making our application more flexible to maintain.
You want to know a little more about the Repository pattern? Read this great article.
Execute the following command to get the latest version of the package:

Create your model normally, but it is important to define the attributes that can be filled from the input form data.
namespace App;
class Post extends Eloquent { // or Ardent, Or any other Model Class
protected $fillable = [
'title',
'author',
...
];
...
}namespace App;
use Prettus\Repository\Eloquent\BaseRepository;
class PostRepository extends BaseRepository {
/**
* Specify Model class name
*
* @return string
*/
function model()
{
return "App\\Post";
}
}Create your repositories easily through the generator.
You must first configure the storage location of the repository files. By default is the "app" folder and the namespace "App". Please note that, values in the paths array are acutally used as both namespace and file paths. Relax though, both foreward and backward slashes are taken care of during generation.
...
'generator'=>[
'basePath'=>app()->path(),
'rootNamespace'=>'App\\',
'paths'=>[
'models' => 'Entities',
'repositories' => 'Repositories',
'interfaces' => 'Repositories',
'transformers' => 'Transformers',
'presenters' => 'Presenters',
'validators' => 'Validators',
'controllers' => 'Http/Controllers',
'provider' => 'RepositoryServiceProvider',
'criteria' => 'Criteria',
]
]You may want to save the root of your project folder out of the app and add another namespace, for example
...
'generator'=>[
'basePath' => base_path('src/Lorem'),
'rootNamespace' => 'Lorem\\'
]Additionally, you may wish to customize where your generated classes end up being saved. That can be accomplished by editing the paths node to your liking. For example:
'generator'=>[
'basePath'=>app()->path(),
'rootNamespace'=>'App\\',
'paths'=>[
'models'=>'Models',
'repositories'=>'Repositories\\Eloquent',
'interfaces'=>'Contracts\\Repositories',
'transformers'=>'Transformers',
'presenters'=>'Presenters'
'validators' => 'Validators',
'controllers' => 'Http/Controllers',
'provider' => 'RepositoryServiceProvider',
'criteria' => 'Criteria',
]
]To generate everything you need for your Model, run this command:
php artisan make:entity Post
This will create the Controller, the Validator, the Model, the Repository, the Presenter and the Transformer classes. It will also create a new service provider that will be used to bind the Eloquent Repository with its corresponding Repository Interface. To load it, just add this to your AppServiceProvider@register method:
$this->app->register(RepositoryServiceProvider::class);You can also pass the options from the repository command, since this command is just a wrapper.
To generate a repository for your Post model, use the following command
php artisan make:repository Post
To generate a repository for your Post model with Blog namespace, use the following command
php artisan make:repository "Blog\Post"
Added fields that are fillable
php artisan make:repository "Blog\Post" --fillable="title,content"
To add validations rules directly with your command you need to pass the --rules option and create migrations as well:
php artisan make:entity Cat --fillable="title:string,content:text" --rules="title=>required|min:2, content=>sometimes|min:10"
The command will also create your basic RESTfull controller so just add this line into your routes.php file and you will have a basic CRUD:
Route::resource('cats', CatsController::class);When running the command, you will be creating the "Entities" folder and "Repositories" inside the folder that you set as the default.
Now that is done, you still need to bind its interface for your real repository, for example in your own Repositories Service Provider.
App::bind('{YOUR_NAMESPACE}Repositories\PostRepository', '{YOUR_NAMESPACE}Repositories\PostRepositoryEloquent');And use
public function __construct({YOUR_NAMESPACE}Repositories\PostRepository $repository){
$this->repository = $repository;
}Alternatively, you could use the artisan command to do the binding for you.
php artisan make:bindings Catsnamespace App\Http\Controllers;
use App\PostRepository;
class PostsController extends BaseController {
/**
* @var PostRepository
*/
protected $repository;
public function __construct(PostRepository $repository){
$this->repository = $repository;
}
....
}Find all results in Repository
$posts = $this->repository->all();Find all results in Repository with pagination
$posts = $this->repository->paginate($limit = null, $columns = ['*']);Find by result by id
$post = $this->repository->find($id);Hiding attributes of the model
$post = $this->repository->hidden(['country_id'])->find($id);Showing only specific attributes of the model
$post = $this->repository->visible(['id', 'state_id'])->find($id);Loading the Model relationships
$post = $this->repository->with(['state'])->find($id);Find by result by field name
$posts = $this->repository->findByField('country_id','15');Find by result by multiple fields
$posts = $this->repository->findWhere([
//Default Condition =
'state_id'=>'10',
'country_id'=>'15',
//Custom Condition
['columnName','>','10']
]);Find by result by multiple values in one field
$posts = $this->repository->findWhereIn('id', [1,2,3,4,5]);Find by result by excluding multiple values in one field
$posts = $this->repository->findWhereNotIn('id', [6,7,8,9,10]);Find all using custom scope
$posts = $this->repository->scopeQuery(function($query){
return $query->orderBy('sort_order','asc');
})->all();Create new entry in Repository
$post = $this->repository->create( Input::all() );Update entry in Repository
$post = $this->repository->update( Input::all(), $id );Delete entry in Repository
$this->repository->delete($id)Delete entry in Repository by multiple fields
$this->repository->deleteWhere([
//Default Condition =
'state_id'=>'10',
'country_id'=>'15',
])php artisan make:criteria MyCriteria
Criteria are a way to change the repository of the query by applying specific conditions according to your needs. You can add multiple Criteria in your repository.
use Prettus\Repository\Contracts\RepositoryInterface;
use Prettus\Repository\Contracts\CriteriaInterface;
class MyCriteria implements CriteriaInterface {
public function apply($model, RepositoryInterface $repository)
{
$model = $model->where('user_id','=', Auth::user()->id );
return $model;
}
}namespace App\Http\Controllers;
use App\PostRepository;
class PostsController extends BaseController {
/**
* @var PostRepository
*/
protected $repository;
public function __construct(PostRepository $repository){
$this->repository = $repository;
}
public function index()
{
$this->repository->pushCriteria(new MyCriteria1());
$this->repository->pushCriteria(MyCriteria2::class);
$posts = $this->repository->all();
...
}
}Getting results from Criteria
$posts = $this->repository->getByCriteria(new MyCriteria());Setting the default Criteria in Repository
use Prettus\Repository\Eloquent\BaseRepository;
class PostRepository extends BaseRepository {
public function boot(){
$this->pushCriteria(new MyCriteria());
// or
$this->pushCriteria(AnotherCriteria::class);
...
}
function model(){
return "App\\Post";
}
}Use skipCriteria before any other chaining method
$posts = $this->repository->skipCriteria()->all();Use popCriteria to remove a criteria
$this->repository->popCriteria(new Criteria1());
// or
$this->repository->popCriteria(Criteria1::class);RequestCriteria is a standard Criteria implementation. It enables filters to perform in the repository from parameters sent in the request.
You can perform a dynamic search, filter the data and customize the queries.
To use the Criteria in your repository, you can add a new criteria in the boot method of your repository, or directly use in your controller, in order to filter out only a few requests.
use Prettus\Repository\Eloquent\BaseRepository;
use Prettus\Repository\Criteria\RequestCriteria;
class PostRepository extends BaseRepository {
/**
* @var array
*/
protected $fieldSearchable = [
'name',
'email'
];
public function boot(){
$this->pushCriteria(app('Prettus\Repository\Criteria\RequestCriteria'));
...
}
function model(){
return "App\\Post";
}
}Remember, you need to define which fields from the model can be searchable.
In your repository set $fieldSearchable with the name of the fields to be searchable or a relation to fields.
protected $fieldSearchable = [
'name',
'email',
'product.name'
];You can set the type of condition which will be used to perform the query, the default condition is "="
protected $fieldSearchable = [
'name'=>'like',
'email', // Default Condition "="
'your_field'=>'condition'
]; public function index()
{
$this->repository->pushCriteria(app('Prettus\Repository\Criteria\RequestCriteria'));
$posts = $this->repository->all();
...
}Request all data without filter by request

]By default RequestCriteria makes its queries using the OR comparison operator for each query parameter.
http://prettus.local/users?search=age:17;email:john@gmail.com
The above example will execute the following query:
SELECT * FROM users WHERE age = 17 OR email = 'john@gmail.com';In order for it to query using the AND, pass the searchJoin parameter as shown below:
http://prettus.local/users?search=age:17;email:john@gmail.com&searchJoin=and

]You can change the name of the parameters in the configuration file config/repository.php
Add a layer of cache easily to your repository
Implements the interface CacheableInterface and use CacheableRepository Trait.
use Prettus\Repository\Eloquent\BaseRepository;
use Prettus\Repository\Contracts\CacheableInterface;
use Prettus\Repository\Traits\CacheableRepository;
class PostRepository extends BaseRepository implements CacheableInterface {
use CacheableRepository;
...
}Done , done that your repository will be cached , and the repository cache is cleared whenever an item is created, modified or deleted.
You can change the cache settings in the file config/repository.php and also directly on your repository.
config/repository.php
'cache'=>[
//Enable or disable cache repositories
'enabled' => true,
//Lifetime of cache
'minutes' => 30,
//Repository Cache, implementation Illuminate\Contracts\Cache\Repository
'repository'=> 'cache',
//Sets clearing the cache
'clean' => [
//Enable, disable clearing the cache on changes
'enabled' => true,
'on' => [
//Enable, disable clearing the cache when you create an item
'create'=>true,
//Enable, disable clearing the cache when upgrading an item
'update'=>true,
//Enable, disable clearing the cache when you delete an item
'delete'=>true,
]
],
'params' => [
//Request parameter that will be used to bypass the cache repository
'skipCache'=>'skipCache'
],
'allowed'=>[
//Allow caching only for some methods
'only' =>null,
//Allow caching for all available methods, except
'except'=>null
],
],It is possible to override these settings directly in the repository.
use Prettus\Repository\Eloquent\BaseRepository;
use Prettus\Repository\Contracts\CacheableInterface;
use Prettus\Repository\Traits\CacheableRepository;
class PostRepository extends BaseRepository implements CacheableInterface {
// Setting the lifetime of the cache to a repository specifically
protected $cacheMinutes = 90;
protected $cacheOnly = ['all', ...];
//or
protected $cacheExcept = ['find', ...];
use CacheableRepository;
...
}The cacheable methods are : all, paginate, find, findByField, findWhere, getByCriteria
Requires prettus/laravel-validator. composer require prettus/laravel-validator
Easy validation with prettus/laravel-validator
In the example below, we define some rules for both creation and edition
use \Prettus\Validator\LaravelValidator;
class PostValidator extends LaravelValidator {
protected $rules = [
'title' => 'required',
'text' => 'min:3',
'author'=> 'required'
];
}To define specific rules, proceed as shown below:
use \Prettus\Validator\Contracts\ValidatorInterface;
use \Prettus\Validator\LaravelValidator;
class PostValidator extends LaravelValidator {
protected $rules = [
ValidatorInterface::RULE_CREATE => [
'title' => 'required',
'text' => 'min:3',
'author'=> 'required'
],
ValidatorInterface::RULE_UPDATE => [
'title' => 'required'
]
];
}use Prettus\Repository\Eloquent\BaseRepository;
use Prettus\Repository\Criteria\RequestCriteria;
class PostRepository extends BaseRepository {
/**
* Specify Model class name
*
* @return mixed
*/
function model(){
return "App\\Post";
}
/**
* Specify Validator class name
*
* @return mixed
*/
public function validator()
{
return "App\\PostValidator";
}
}Alternatively, instead of using a class to define its validation rules, you can set your rules directly into the rules repository property, it will have the same effect as a Validation class.
use Prettus\Repository\Eloquent\BaseRepository;
use Prettus\Repository\Criteria\RequestCriteria;
use Prettus\Validator\Contracts\ValidatorInterface;
class PostRepository extends BaseRepository {
/**
* Specify Validator Rules
* @var array
*/
protected $rules = [
ValidatorInterface::RULE_CREATE => [
'title' => 'required',
'text' => 'min:3',
'author'=> 'required'
],
ValidatorInterface::RULE_UPDATE => [
'title' => 'required'
]
];
/**
* Specify Model class name
*
* @return mixed
*/
function model(){
return "App\\Post";
}
}Validation is now ready. In case of a failure an exception will be given of the type: Prettus\Validator\Exceptions\ValidatorException
Presenters function as a wrapper and renderer for objects.
Requires Fractal. composer require league/fractal
There are two ways to implement the Presenter, the first is creating a TransformerAbstract and set it using your Presenter class as described in the Create a Transformer Class.
The second way is to make your model implement the Transformable interface, and use the default Presenter ModelFractarPresenter, this will have the same effect.
php artisan make:transformer Post
This will generate the class beneath.
use League\Fractal\TransformerAbstract;
class PostTransformer extends TransformerAbstract
{
public function transform(\Post $post)
{
return [
'id' => (int) $post->id,
'title' => $post->title,
'content' => $post->content
];
}
}php artisan make:presenter Post
The command will prompt you for creating a Transformer too if you haven't already.
use Prettus\Repository\Presenter\FractalPresenter;
class PostPresenter extends FractalPresenter {
/**
* Prepare data to present
*
* @return \League\Fractal\TransformerAbstract
*/
public function getTransformer()
{
return new PostTransformer();
}
}use Prettus\Repository\Eloquent\BaseRepository;
class PostRepository extends BaseRepository {
...
public function presenter()
{
return "App\\Presenter\\PostPresenter";
}
}Or enable it in your controller with
$this->repository->setPresenter("App\\Presenter\\PostPresenter");If you recorded a presenter and sometime used the skipPresenter() method or simply you do not want your result is not changed automatically by the presenter.
You can implement Presentable interface on your model so you will be able to present your model at any time. See below:
In your model, implement the interface Prettus\Repository\Contracts\Presentable and Prettus\Repository\Traits\PresentableTrait
namespace App;
use Prettus\Repository\Contracts\Presentable;
use Prettus\Repository\Traits\PresentableTrait;
class Post extends Eloquent implements Presentable {
use PresentableTrait;
protected $fillable = [
'title',
'author',
...
];
...
}There, now you can submit your Model individually, See an example:
$repository = app('App\PostRepository');
$repository->setPresenter("Prettus\\Repository\\Presenter\\ModelFractalPresenter");
//Getting the result transformed by the presenter directly in the search
$post = $repository->find(1);
print_r( $post ); //It produces an output as array
...
//Skip presenter and bringing the original result of the Model
$post = $repository->skipPresenter()->find(1);
print_r( $post ); //It produces an output as a Model object
print_r( $post->presenter() ); //It produces an output as arrayYou can skip the presenter at every visit and use it on demand directly into the model, for it set the $skipPresenter attribute to true in your repository:
use Prettus\Repository\Eloquent\BaseRepository;
class PostRepository extends BaseRepository {
/**
* @var bool
*/
protected $skipPresenter = true;
public function presenter()
{
return "App\\Presenter\\PostPresenter";
}
}namespace App;
use Prettus\Repository\Contracts\Transformable;
class Post extends Eloquent implements Transformable {
...
/**
* @return array
*/
public function transform()
{
return [
'id' => (int) $this->id,
'title' => $this->title,
'content' => $this->content
];
}
}Prettus\Repository\Presenter\ModelFractalPresenter is a Presenter default for Models implementing Transformable
use Prettus\Repository\Eloquent\BaseRepository;
class PostRepository extends BaseRepository {
...
public function presenter()
{
return "Prettus\\Repository\\Presenter\\ModelFractalPresenter";
}
}Or enable it in your controller with
$this->repository->setPresenter("Prettus\\Repository\\Presenter\\ModelFractalPresenter");Use skipPresenter before any other chaining method
$posts = $this->repository->skipPresenter()->all();or
$this->repository->skipPresenter();
$posts = $this->repository->all();
