Features

Quick Example (TL;DR)

The Rinvex\Repository\Repositories\BaseRepository is an abstract class with bare minimum that concrete implementations must extend.

The Rinvex\Repository\Repositories\EloquentRepository is currently the only available repository implementation (more to come in the future and you can develop your own), it makes it easy to create new eloquent model instances and to manipulate them easily. To use EloquentRepository your repository MUST extend it first:

namespace App\Repositories;

use Rinvex\Repository\Repositories\EloquentRepository;

class FooRepository extends EloquentRepository
{
    protected $repositoryId = 'rinvex.repository.uniqueid';

    protected $model = 'App\Models\User';
}

That's it, you're done! Yes, it's that simple.

But if you'd like more control over the container instance, or would like to pass model name dynamically you can alternatively do as follow:

namespace App\Repositories;

use Illuminate\Contracts\Container\Container;
use Rinvex\Repository\Repositories\EloquentRepository;

class FooRepository extends EloquentRepository
{
    // Instantiate repository object with required data
    public function __construct(Container $container)
    {
        $this->setContainer($container)
             ->setModel(\App\Models\User::class)
             ->setRepositoryId('rinvex.repository.uniqueid');

    }
}

Now inside your controller, you can either instantiate the repository traditionally through $repository = new \App\Repositories\FooRepository(); or to use Laravel's awesome dependency injection and let the IoC do the magic:

namespace App\Http\Controllers;

use App\Repositories\FooRepository;

class BarController
{
    // Inject `FooRepository` from the IoC
    public function baz(FooRepository $repository)
    {
        // Find entity by primary key
        $repository->find(1);

        // Find all entities
        $repository->findAll();

        // Create a new entity
        $repository->create(['name' => 'Example']);
    }
}

You are good to go. Integration is done and you can now use all the available methods, proceed to the Usage section for an example.

Configuration

If you followed the previous integration steps, then your published config file reside at config/rinvex.repository.php.

Config options are very expressive and self explanatory, as follows:

return [

// Disable repository cache clear
$repository->enableCacheClear(false);

// Determine if repository cache clear is enabled
$cacheClearStatus = $repository->isCacheClearEnabled();

createModel()

$repositoryModelInstance = $repository->createModel();

forgetCache()

The forgetCache() method forgets the repository cache:

$repository->forgetCache();

with()

The with method sets the relationships that should be eager loaded:

// Pass a string
$repository->with('relationship');

// Or an array
$repository->with(['relationship1', 'relationship2']);

where()

The where method adds a basic where clause to the query:

$repository->where('slug', '=', 'example');

whereIn()

The whereIn method adds a "where in" clause to the query:

$repository->whereIn('id', [1, 2, 5, 8]);

use Illuminate\Database\Eloquent\Builder;

$repository->whereHas('attachments', function (Builder $builder) use ($attachment) {
    $builder->where('attachment_id', $attachment->id);
});

Note: All of the where* methods are chainable & could be called multiple times in a single request. It will hold all where clauses in an array internally and apply them all before executing the query.

offset()

The offset method sets the "offset" value of the query:

$repository->offset(5);

limit()

The limit method sets the "limit" value of the query:

$repository->limit(9);

The findOrFail() method finds an entity by its primary key or throw an exception:

$entity = $repository->findOrFail(1);

findOrNew()

The findOrNew() method finds an entity by its primary key or return fresh entity instance:

$entity = $repository->findOrNew(1);

findBy()

The findBy method finds an entity by one of it's attributes:

$entity = $repository->findBy('id', 1);

findFirst()

The findFirst method finds first entity:

$firstEntity = $repository->findFirst();

findAll()

The findAll method finds all entities:

$allEntities = $repository->findAll();

paginate()

The paginate method paginates all entities:

$entitiesPagination = $repository->paginate(15, ['*'], 'page', 2);

As you can guess, this query the first 15 records, in the second page.

simplePaginate()

The simplePaginate method paginates all entities into a simple paginator:

$entitiesSimplePagination = $repository->simplePaginate(15);

$includedEntities = $repository->findwhereIn(['id', [1, 2, 5, 8]]);

findWhereNotIn()

The findWhereNotIn method finds all entities matching whereNotIn conditions:

$excludedEntities = $repository->findWhereNotIn(['id', [1, 2, 5, 8]]);

findWhereHas()

The findWhereHas method finds all entities matching whereHas conditions:

use Illuminate\Database\Eloquent\Builder;

$entities = $repository->findWhereHas(['attachments', function (Builder $builder) use ($attachment) {
    $builder->where('attachment_id', $attachment->id);
}]);

Notes:

Example of filtered findAll method:

$allFilteredEntities = $repository->where('slug', '=', 'example')->findAll();

Another example of filtered findFirst method with chained clauses:

$allFilteredEntities = $repository->where('name', 'LIKE', '%TEST%')->where('slug', '=', 'example')->findFirst();

$updatedEntity = $repository->update(1, ['name' => 'Example2']);

store()

The store method stores the entity with the given attributes:

// Existing Entity
$storedEntity = $repository->store(1, ['name' => 'Example2']);

// New Entity
$storedEntity = $repository->store(null, ['name' => 'Example2']);

Note: This method is just an alias for both create & update methods. It's useful in case where single form is used for both create & update processes.

delete()

The delete method deletes an entity with the given id:

$deletedEntity = $repository->delete(1);

beginTransaction()

The beginTransaction method starts a database transaction:

$repository->beginTransaction();

commit()

The commit method commits a database transaction:

$repository->commit();

rollBack()

The rollback method rollbacks a database transaction:

$repository->rollBack();

Notes:

Code To An Interface

As a best practice, it's recommended to code for an interface, specifically for scalable projects. The following example explains how to do so.

First, create an interface (abstract) for every entity you've:

use Rinvex\Repository\Contracts\CacheableContract;
use Rinvex\Repository\Contracts\RepositoryContract;

interface UserRepositoryContract extends RepositoryContract, CacheableContract
{
    //
}

Second, create a repository (concrete implementation) for every entity you've:

use Rinvex\Repository\Repositories\EloquentRepository;

class UserEloquentRepository extends EloquentRepository implements UserRepositoryContract
{
    //
}

Now in a Laravel Service Provider bind both to the IoC (inside the register method):

$this->app->bind(UserRepositoryContract::class, UserEloquentRepository::class)

This way we don't have to instantiate the repository manually, and it's easy to switch between multiple implementations. The IoC Container will take care of the required dependencies.

Note: Checkout Laravel's Service Providers and Service Container documentation for further details.

Add Custom Implementation

Since we're focusing on abstracting the data layer, and we're separating the abstract interface from the concrete implementation, it's easy to add your own implementation.

Say your domain model uses a web service, or a filesystem data store as it's data source, all you need to do is just extend the BaseRepository class, that's it. See:

class FilesystemRepository extends BaseRepository
{
    // Implement here all `RepositoryContract` methods that query/persist data to & from filesystem or whatever datastore
}

EloquentRepository Fired Events

Repositories fire events at every action, like create, update, delete. All fired events are prefixed with repository's identifier (you set before in your repository's constructor) like the following example:

For your convenience, the events suffixed with .entity.created, .entity.updated, or .entity.deleted have listeners that take actions accordingly. Usually we need to flush cache -if enabled & exists- upon every success action.

There's one more event rinvex.repository.uniqueid.entity.cache.flushed that's fired on cache flush. It has no listeners by default, but you may need to listen to it if you've model relations for further actions.

Note: Rinvex Repository adheres to PSR-4: Autoloader and expects other packages that uses it to adhere to the same standard as well. It's required for Automatic Guessing, such as when repository model is missing, it will be guessed automatically and resolved accordingly, and while that full directory structure might not required, it's the standard for all Rinvex packages.

Automatic Guessing

While it's recommended to explicitly set IoC container, repository identifier, and repository model; This package is smart enough to guess any of these required data whenever missing.

Flexible & Granular Caching

Rinvex Repository has a powerful, yet simple and granular caching system, that handles almost every edge case. While you can enable/disable your application's cache as a whole, you have the flexibility to enable/disable cache granularly for every individual query! That gives you the ability to except certain queries from being cached even if the method is normally cached by default or otherwise.

Let's see what caching levels we can control:

Whole Application Cache

Checkout Laravel's Cache documentation for more details.

Individual Query Cache

Change cache per query or disable it:

// Set cache lifetime for this individual query to 123 seconds
$repository->setCacheLifetime(123);

// Set cache lifetime for this individual query to forever
$repository->setCacheLifetime(-1);

// Disable cache for this individual query
$repository->setCacheLifetime(0);

Change cache driver per query:

// Set cache driver for this individual query to redis
$repository->setCacheDriver('redis');

Both setCacheLifetime & setCacheDriver methods are chainable:

// Change cache lifetime & driver on runtime
$repository->setCacheLifetime(123)->setCacheDriver('redis')->findAll();

// Use default cache lifetime & driver
$repository->findAll();

Unless disabled explicitly, cache is enabled for all repositories by default, and kept for as long as your rinvex.repository.cache.lifetime config value, using default application's cache driver cache.default (which could be changed per query as well).

Caching results is totally up to you, while all retrieval find* methods have cache enabled by default, you can enable/disable cache for individual queries or control how it's being cached, for how long, and using which driver as you wish.

Temporary Skip Individual HTTP Request Cache

Lastly, you can skip cache for an individual request by passing the following query string in your URL skipCache=true. You can modify this parameter to whatever name you may need through the rinvex.repository.cache.skip_uri config option.
