Introduction

Queryable gives you query builder helpers such as Filter and OrderBy to make APIs easier to create.

Requirements

The following is required to use Queryable

Laravel 
PHP 7

Installation

To get started, install Queryable via the Composer package manager:

composer require hasnath/queryable

Add the QueryableServiceProvider to your providers in config/app.php

HasnatH\Queryable\Providers\QueryableServiceProvider::class

Publish the configuration file

php artisan vendor:publish --provider="HasnatH\Queryable\Providers\QueryableServiceProvider"

Configuration

The configuration file will be published config/queryable.php

<?php

return [
    'filter' => [
        'separator' => env('QUERYABLE_FILTER_SEPARATOR', ',')
    ],

    'orderBy' => [
        'separator' => env('QUERYABLE_ORDER_BY_SEPARATOR', ',')
    ],
];

Usage

Instantiate a new Queryable and pass in the Model to be used

Use the available Queryable methods

<?php

use App\User;
use HasnatH\Queryable\Queryable;

class UserService 
{    
    protected $queryable;

    public function index() 
    {
        $queryable = new Queryable(User::class);

        $query = User::query();
        
        $query = $queryable->filter($query, request()->get('filter'));
        $query = $queryable->orderBy($query, request()->get('orderBy'));
    
        return $query->get();
    }

}

Filter

Queryable gives you the ability to easily filter database queries

Configuration

Specific configuration for the filter method can be found in the filter array inconfig/queryable.php

As default, all fields in a model can be filtered

To override which fields you want to filter by add the following in to your model

public static $filterable = [
    'first_name',
    'last_name'
];

Any filters that contain a field that is not present in the model/filterable will be ignored.

Format

To apply filters, call the filter method on your Queryable instance. The filter method accepts two parameters: $query, $filters

The $query parameter is an instance of your query builder

$query = User::query();

$query = auth()->user();

The $filter parameter is an array of your filters in the following format

[
    "FIELD,VALUE,OPERATOR",
]

The FIELD and VALUE fields are required for each filter.

The OPERATOR field is optional and will default to =

The following OPERATORS can be used

= 
< 
> 
<= 
>=
<>
!=
LIKE
NOT LIKE
BETWEEN
ILIKE

You can apply as many filters as you would like.

For example, to apply filters for first_name and last_name:

[
    ["first_name,John"],
    ["last_name,Smith"]   
]

The default separator for the filter method is ,

This value is retrieved from config/queryable.php filter.separator

To change the separator, update the filter.separator value in the config or add an .env variable

QUERYABLE_FILTER_SEPARATOR=|

You will then need to pass filters in the following format

[
    ["first_name|John"],
    ["last_name|Smith"]   
]

Usage Example

The following will pass any filters passed via the request and apply them

public function index() 
{
    $queryable = new Queryable(User::class);
    
    $filters = request()->get('filter');

    $query = User::query();
    
    $query = $queryable->filter($query, $filters);

    return $query->get();
}

To get the users that have the first_name John and id greater than 3

GET /users?filter[]=first_name,John&filter[]=id,3,>

OrderBy

Queryable gives you the ability to easily order database queries

Configuration

Specific configuration for the orderBy method can be found in the orderBy array inconfig/queryable.php

As default, you can apply an order on all fields in a model

To override which fields you want to order by add the following in to your model

public static $orderable = [
    'first_name',
    'last_name'
];

Any orders that contain a field that is not present in the model/orderable will be ignored.

Format

To apply ordering, call the orderBy method on your Queryable instance. The orderBy method accepts two parameters: $query, $fields

The $query parameter is an instance of your query builder

$query = User::query();

$query = auth()->user();

The $fields parameter is an array of your order fields in the following format

[
    "FIELD,ORDER",
]

The FIELD field is required for each order.

The ORDER field is optional and will default to ASC

The following ORDER values can be used

ASC
DESC

You can apply as many orders as you would like.

For example, to order by first_name and then last_name

[
    ["first_name"],
    ["last_name,DESC"]   
]

The default separator for the orderBy method is ,

This value is retrieved from config/queryable.php orderBy.separator

To change the separator, update the orderBy.separator value in the config or add an .env variable

QUERYABLE_ORDER_BY_SEPARATOR=|

You will then need to pass filters in the following format

[
    ["first_name"],
    ["last_name|DESC"]   
]

Usage Example

The following will pass any orders passed via the request and apply them

public function index() 
{
    $queryable = new Queryable(User::class);
    
    $filters = request()->get('filter');

    $query = User::query();
    
    $query = $queryable->orderBy($query, $filters);

    return $query->get();
}

To order by the first_name in ascending order and then the id in descending order

GET /users?orderBy[]=first_name&orderBy[]=id,DESC
