install

composer require dezsidog/laravel-repository

usage

create model

namespace App;

class Post extends Eloquent {

    protected $fillable = [
        'title',
        'author',
        ...
     ];

     ...
}

create repository

namespace App\Repository;

use Dezsidog\Repository;
use App\Post;

class PostRepository extends Repository {
    protected $model = Post::class;
}

add repository to controller

namespace App\Http\Controllers;

use App\Repository\PostRepository;

class PostsController extends BaseController {

    /**
     * @var PostRepository
     */
    protected $posts;

    public function __construct(PostRepository $repository){
        $this->posts = $repository;
    }
}

then you can

public function someMethod(){
    $this->posts->find(...);
    $this->posts->findBy(...);
    $this->posts->all();
    $this->posts->paginate(...); // deprecated
    $this->posts->create(...);
    $this->posts->update(...);
    $this->posts->delete(...);
}

expands

if model has relations.

namespace App;

use App\User;
use App\Type;

class Post extends Eloquent {

    protected $fillable = [
        'title',
        'author',
        'user_id',
        'type_id',
        ...
     ];

    public function user(){
        return $this->belongTo(User::class);
    }
    
    public function type(){
        return $this->belongTo(Type::class);
    }
     ...
}

you can

just append expands field to url:

https://www.xxxx.com/path/to/post-list?expands=user,type

or make expands auto

namespace App\Repository;

use Dezsidog\Repository;
use App\Post;

class PostRepository extends Repository {
    protected $model = Post::class;
    protected $expands = [
        'user',
        'type',
    ];
}

filters

to search something by

https://www.xxxx.com/path/to/post-list?filters[type_id]=3&filters[user_id]=1

you can use relations

https://www.xxxx.com/path/to/post-list?filters[type.id]=3&filters[user.id]=1

custom filters

add method named filterBy + key name, to custom filters.

namespace App\Repository;

use Dezsidog\Repository;
use App\Post;
use Illuminate\Database\Eloquent\Builder;

class PostRepository extends Repository {
    protected $model = Post::class;
    
    public function filterByNameOrTypeName(Builder $query, $value){
        $query->leftJoin('users', 'users.id', '=', 'posts.user_id')
            ->leftJoin('types', 'type.id', '=', 'posts.type_id')
            ->where(function(Builder $query) use ($value) {
                $query->where('users.username', 'like', '%'.$value.'%')
                    ->orWhere('types.name', 'like', '%'.$value.'%')
            });
    }
}

then make url:

https://www.xxxx.com/path/to/post-list?filters[name-or-type-name]=x

you can just cover the exists field

namespace App\Repository;

use Dezsidog\Repository;
use App\Post;
use Illuminate\Database\Eloquent\Builder;

class PostRepository extends Repository {
    protected $model = Post::class;
    
    public function filterByTitle(Builder $query, $value){
        $query->where('posts.title', '=', $value);
    }
}

sort

to sort something by

https://www.xxxx.com/path/to/post-list?sorts[type_id]=asc&sorts[user_id]=desc

you can not use relations

custom sorts

add method named sortBy + key name, to custom sorts.

namespace App\Repository;

use Dezsidog\Repository;
use App\Post;
use Illuminate\Database\Eloquent\Builder;

class PostRepository extends Repository {
    protected $model = Post::class;
    
    public function sortByName(Builder $query, $value){
        $query->orderby('name',$value);
    }
}
