README

This library extends the functionalities of "rebing/graphql-laravel," providing a comprehensive solution for managing pagination and applying advanced filters to GraphQL queries in Laravel applications.

Installation

Use Composer to install the library:

composer require kevinoo/graphql-laravel-filters

Usage

To utilize pagination in GraphQL queries, simply extend the AbstractPaginateQuery class provided by this library and use it in query resolvers.

use kevinoo\GraphQL\Queries;

class MyCustomModelQuery extends AbstractPaginateQuery 
{
// public const GENERIC_FILTERS = true;
// public const TRASHED_FILTER = true;
// public const MAX_LIMIT_RESULTS = 1000;

 protected $attributes = [
 'name' => 'Name of Query',
 ];

 public function getGraphQLType(): string
 {
 return 'Your GraphQL Type';
 }

 public function args(): array
 {
 return parent::args() + [
 'filters' => [
 'type' => GraphQL::type('Your GraphQL FilterInput'),
 ],
 ];
 }

 protected function resolveModelBuilder( array $args ): Builder
 {
 $builder = YourModel::query();

 $order_by = ($args['orders'] ?? []) ?: ['domain'=>'ASC'];
 foreach( $order_by as $column => $direction ){
 $builder->orderBy($column,$direction);
 }

 return $builder;
 }

 protected function getGenericFiltersKeys(): array
 {
 return [
 'your_input_key_1' => 'model_attribute_1', // Input value can be string, int, boolean or array
 'your_input_key_2' => new AdvancedSearch('model_attribute_to_apply_advanced_search'),
 'your_input_key_3_array' => 'model_attribute_2',
 ];
 }

 protected function getPipelineFiltersSteps(): array
 {
 return parent::getPipelineFiltersSteps() + [
 // Add your other custom filters class
 ];
 }
}
