Repository Pattern in Laravel. The package allows to filter by request out-of-the-box, as well as to integrate customized criteria and any kind of filters.
Via Composer
$ composer require awes-io/repositoryThe package will automatically register itself.
First publish config:
php artisan vendor:publish --provider="AwesIO\Repository\RepositoryServiceProvider" --tag="config"// $repository->smartPaginate() related parameters
'smart_paginate' => [
// name of request parameter to take paginate by value from
'request_parameter' => 'limit',
// default paginate by value
'default_limit' => 15,
// max paginate by value
'max_limit' => 100,
]https://example.com/news?title=Title&custom=value&orderBy=name_desc
It will automatically apply built-in constraints onto the query as well as any custom scopes and criteria you need:
protected $searchable = [
// where 'title' equals 'Title'
'title',
];
protected $scopes = [
// and custom parameter used in your scope
'custom' => MyScope::class,
];class MyScope extends ScopeAbstract
{
public function scope($builder, $value, $scope)
{
return $builder->where($scope, $value)->orWhere(...);
}
}Ordering by any field is available:
protected $scopes = [
// orderBy field
'orderBy' => OrderByScope::class,
];Package can also apply any custom criteria:
return $this->news->withCriteria([
new MyCriteria([
'category_id' => '1', 'name' => 'Name'
])
...
])->get();Create your model:
namespace App;
use Illuminate\Database\Eloquent\Model;
class News extends Model
{
...
}Extend it from AwesIO\Repository\Eloquent\BaseRepository and provide entity() method to return full model class name:
namespace App;
use AwesIO\Repository\Eloquent\BaseRepository;
class NewsRepository extends BaseRepository
{
public function entity()
{
return News::class;
}
}use App\NewsRepository;
class NewsController extends BaseController
{
protected $news;
public function __construct(NewsRepository $news)
{
$this->news = $news;
}
....
}Execute the query as a "select" statement or get all results:
$news = $this->news->get();Execute the query and get the first result:
$news = $this->news->first();Find a model by its primary key:
$news = $this->news->find(1);Add basic where clauses and execute the query:
$news = $this->news->->findWhere([
// where id equals 1
'id' => '1',
// other "where" operations
['news_category_id', '<', '3'],
...
]);Paginate the given query:
$news = $this->news->paginate(15);Paginate the given query into a simple paginator:
$news = $this->news->simplePaginate(15);Paginate the given query by 'limit' request parameter:
$news = $this->news->smartPaginate();Add an "order by" clause to the query:
$news = $this->news->orderBy('title', 'desc')->get();Save a new model and return the instance:
$news = $this->news->create($request->all());Update a record:
$this->news->update($request->all(), $id);Delete a record by id:
$this->news->destroy($id);Attach models to the parent:
$this->news->attach($parentId, $relationship, $idsToAttach);Detach models from the relationship:
$this->news->detach($parentId, $relationship, $idsToDetach);Find model or throw an exception if not found:
$this->news->findOrFail($id);Execute the query and get the first result or throw an exception:
$this->news->firstOrFail();Criteria are a way to build up specific query conditions.
use AwesIO\Repository\Contracts\CriterionInterface;
class MyCriteria implements CriterionInterface {
protected $conditions;
public function __construct(array $conditions)
{
$this->conditions = $conditions;
}
public function apply($entity)
{
foreach ($this->conditions as $field => $value) {
$entity = $entity->where($field, '=', $value);
}
return $entity;
}
}Multiple Criteria can be applied:
use App\NewsRepository;
class NewsController extends BaseController
{
protected $news;
public function __construct(NewsRepository $news)
{
$this->news = $news;
}
public function index()
{
return $this->news->withCriteria([
new MyCriteria([
'category_id' => '1', 'name' => 'Name'
]),
new WhereAdmin(),
...
])->get();
}
}In your repository define which fields can be used to scope your queries by setting $searchable property.
protected $searchable = [
// where 'title' equals parameter value
'title',
// orWhere equals
'body' => 'or',
// where like
'author' => 'like',
// orWhere like
'email' => 'orLike',
];Search by searchables:
public function index($request)
{
return $this->news->scope($request)->get();
}https://example.com/news?title=Title&body=Text&author=&email=gmail
Also several serchables enabled by default:
protected $scopes = [
// orderBy field
'orderBy' => OrderByScope::class,
// where created_at date is after
'begin' => WhereDateGreaterScope::class,
// where created_at date is before
'end' => WhereDateLessScope::class,
];$this->news->scope($request)->get();Enable ordering for specific fields by adding $orderable property to your model class:
public $orderable = ['email'];https://example.com/news?orderBy=email_desc&begin=2019-01-24&end=2019-01-26
orderBy=email_desc will order by email in descending order, orderBy=email - in ascending
You can also build your own custom scopes. In your repository override scope() method:
public function scope($request)
{
// apply build-in scopes
parent::scope($request);
// apply custom scopes
$this->entity = (new NewsScopes($request))->scope($this->entity);
return $this;
}Create your scopes class and extend ScopesAbstract
use AwesIO\Repository\Scopes\ScopesAbstract;
class NewsScopes extends ScopesAbstract
{
protected $scopes = [
// here you can add field-scope mappings
'field' => MyScope::class,
];
}Now you can build any scopes you need:
use AwesIO\Repository\Scopes\ScopeAbstract;
class MyScope extends ScopeAbstract
{
public function scope($builder, $value, $scope)
{
return $builder->where($scope, $value);
}
}Package provides useful artisan command:
php artisan repository:generate Models/Order --scope=SearchMain repository: App\Repositories\Orders\OrdersRepository
Main scopes class: App\Repositories\Orders\Scopes\OrdersScopes
Individual search scope class: App\Repositories\Orders\Scopes\SearchOrdersScope
