Overview

The Filterable trait is designed to be used within Eloquent models in a Laravel application. It provides a convenient way to apply filters to Eloquent queries based on HTTP request parameters. This trait supports filtering by model attributes as well as by related models.

Installation

Add the package to your project using Composer:

composer require usermp/laravel-filter

Add the Filterable trait to your Eloquent model:

use Usermp\LaravelFilter\Traits\Filterable;

class YourModel extends Model
{
    use Filterable;

    // Define the attributes that can be filtered
    protected $filterable = [
        'attribute1',
        'attribute2',
        // Add other filterable attributes
    ];

    // Define the relationships that can be filtered
    protected $filterableRelations = [
        'relation1',
        'relation2',
        // Add other filterable relations
    ];
}

Usage

To use the Filterable trait, simply call the filter scope on your model query and pass the HTTP request parameters.

use App\Models\YourModel;

$filteredResults = YourModel::filter()->get();

The trait will automatically process the request parameters, apply the relevant filters to the query, and return the filtered results.

Examples

Single Select Filtering

Assume you have a Post model with title and content as filterable attributes, and a User relation as a filterable relation.

use Usermp\LaravelFilter\Traits\Filterable;

class Post extends Model
{
    use Filterable;

    protected $filterable = ['title', 'content'];
    protected $filterableRelations = ['user'];
}

You can filter posts by title, content, or user attributes using the following HTTP request parameters:

GET /posts?title=example&user.name=john

This request will filter posts with a title containing "example" and related user names containing "john".

Multi-Select Filtering

Assume you want to filter posts by multiple categories. The categories attribute is an array of category IDs.

use Usermp\LaravelFilter\Traits\Filterable;

class Post extends Model
{
    use Filterable;

    protected $filterable = ['title', 'content', 'categories'];
    protected $filterableRelations = ['user'];
}

You can filter posts by multiple categories using the following HTTP request parameters:

GET /posts?categories[]=1&categories[]=2&categories[]=3

This request will filter posts that belong to categories with IDs 1, 2, and 3.

Filtering by Related Models with Multi-Select

You can also filter related models using multi-select. For instance, filtering posts by multiple user roles:

use Usermp\LaravelFilter\Traits\Filterable;

class Post extends Model
{
    use Filterable;

    protected $filterable = ['title', 'content'];
    protected $filterableRelations = ['user'];
}

Filter posts by users with multiple roles:

GET /posts?user---role['equal']=admin

This request will filter posts authored by users who have either the "admin".
