README

Extension bundle for Symfony's KnpPaginatorBundle that allows to paginate DoctrineMongoDBBundle Doctrine\ODM\MongoDB\Aggregation\Builder.

Requirements

Bundle uses MongoDB $facet operator which is available since MongoDB 3.4.

Installation with Symfony Flex

Open a command console, enter your project directory and execute:

$ composer require ludo444/aggregation-builder-pagination-bundle

Installation without Symfony Flex

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require ludo444/aggregation-builder-pagination-bundle

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

// config/bundles.php

return [
    // ...
    Ludo\Bundle\AggregationBuilderPaginationBundle\LudoAggregationBuilderPaginationBundle::class => ['all' => true],
];

Usage

Doctrine\ODM\MongoDB\Aggregation\Builder needs to be passed into paginate() method. Be aware that most of the Builder methods are returning Doctrine\ODM\MongoDB\Aggregation\Stage. So you need to do eg.:

// src/Repository/ExampleRepository.php
use Doctrine\ODM\MongoDB\Aggregation\Builder as AggregationBuilder;
// ...

class ExampleRepository extends Repository
{
    public function getExamples(): AggregationBuilder
    {
        $ab = $this->createAggregationBuilder();
        
        $ab->hydrate(Example::class)
            ->match()
                ->field('field')
                ->equals('value');
        
        return $ab;
    }
}

As ->equals('value') would not return AggregationBuilder, the code would throw an Exception if you return the result of that method directly. Now to paginate the example repository method, you can just do:

// src/Subfolder/ExamplePagination.php
// ...

class ExamplePagination
{
    // ...

    public function __construct(DocumentManager $manager, PaginatorInterface $paginator)
    {
        $this->manager = $manager;
        $this->paginator = $paginator;
    }

    public function getPaginatedExamples(): PaginationInterface
    {
        return $this->paginator->paginate(
            $this->manager->getRepository(ExampleRepository::class)->getExamples()
        );
    }
}
