QBJSParserBundle

This is a Symfony bundle, which can be used with jQuery QueryBuilder.
- It will parse JSON coming from the frontend, and let you execute it as a Doctrine ORM query.
- It will give you JSON to generate the frontend, based on your Doctrine ORM entities and configuration.
- It is based on QBJSParser, which can be used without Symfony.

It has two useful services:

• fl_qbjs_parser.json_query_parser.doctrine_orm_parser based on class FL\QBJSParserBundle\Service\JsonQueryParser\DoctrineORMParser
  • This will parse a $jsonString coming from JQuery QueryBuilder, and a $className, into a FL\QBJSParser\Parsed\Doctrine\ParsedRuleGroup.
  • The ParsedRuleGroup has two properties, $dqlString and $parameters, accessible via getters.
  • Use the ParsedRuleGroup properties, to create a Doctrine Query.
  • This service is to be used with DoctrineORM.
  • This service implements JsonQueryParserInterface. More parsers could exist for other ORMs / ODMs.
• fl_qbjs_parser.builders based on class FL\QBJSParserBundle\Service\JavascriptBuilders
  • Use the service's getBuilders(), to fetch an array of FL\QBJSParserBundle\Model\Builder\Builder instances.
  • Each Builder comes with five properties, accessible via getters, $className, $jsonString, $humanReadableName, $builderId, and $resultColumns.
  • Use the properties of a Builder, to instantiate a JQuery Query Builder in your front-end.

Installation

• composer require fourlabs/qbjs-parser-bundle
• Add the Bundle to app/AppKernel.php

<?php

    //...
    $bundles = [
        //...
        new FL\QBJSParserBundle\FLQBJSParserBundle(),
    ];

• Set up configuration, as detailed below.

Configuration Example

fl_qbjs_parser:
    builders: # these are used for service fl_qbjs_parser.builders
        product_report_builder:
            class: AppBundle\Entity\Product # this class must exist in doctrine_class_and_mappings
            human_readable_name: 'Product Report Builder'
            # result_columns
            # Not being used inside the bundle, but you can use them in your own way 
            # Make sure not to use OnetoMany or ManyToMany properties here. That makes no sense!
            # I.e. You can use direct properties of the class, ManyToOne, and OneToOne properties.
            result_columns: 
                -
                    column_machine_name: id

Usage Example

fl_qbjs_parser.json_query_parser.doctrine_orm_parser

<?php
    namespace App\Controller;

    //...
    use Symfony\Component\HttpFoundation\Request;
    use Symfony\Bundle\FrameworkBundle\Controller\Controller;
    use AppBundle\Entity\Product;

    class ProductController extends Controller
    {
        public function reportsAction(Request $request, string $jsonString)
        {
             $parsedRuleGroup = $this->get('fl_qbjs_parser.json_query_parser.doctrine_orm_parser')->parseJsonString($jsonString, Product::class);

             $query = $this->get('doctrine.orm.entity_manager')->createQuery($parsedRuleGroup->getQueryString());
             $query->setParameters($parsedRuleGroup->getParameters());
             $results = $query->execute();

             //...
        }
    } 

fl_qbjs_parser.builders

<?php
    namespace App\Controller;

    //...
    use Symfony\Component\HttpFoundation\Request;
    use Symfony\Bundle\FrameworkBundle\Controller\Controller;

    class ReportController extends Controller
    {
        public function reportBuilderAction(Request $request)
        {
             $builders = $this->get('fl_qbjs_parser.builders')->getBuilders();

             return $this->render('default/index.html.twig', [
                 'builders' => $builders,
             ]);

             //...
        }
    } 

Events

The bundle also comes with an event, that allows you to override fl_qbjs_parser.builders. You can currently override values, the input type, and operators.

Here's an example of the configuration for a listener, for such an event.

services:
    app.listener.override_builders:
        class: AppBundle\EventListener\OverrideBuildersListener
        arguments:
        tags:
            - { name: kernel.event_listener, event: fl_qbjs_parser.filter_set_event, method: onFilterSet }
