Installation

Via Composer

$ composer require awes-io/repository

The package will automatically register itself.

Configuration

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' => 10,
    // max paginate by value
    'max_limit' => 100,
]

Overview

Package allows you to filter data based on incoming request parameters:
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();

Usage

Create a Model

Create your model:

namespace App;

use Illuminate\Database\Eloquent\Model;

class News extends Model 
{
    ...
}

Create a Repository

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 built-in methods

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();

Create a Criteria

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();
    }
}

Scope, Filter and Order

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);
    }
}
