Provides a Eloquent query builder for Laravel or Lumen

This package allows you to build eloquent queries, based on request parameters. It greatly reduces the complexity of the queries and conditions, which will make your code cleaner.

Basic Usage

Suppose we want to get the list of the users with the requested parameters as follows:

//Get api/user/search?age_more_than=25&gender=male&has_published_post=true
[
    'age_more_than'  => '25',
    'gender'         => 'male',
    'has_published_post' => 'true',
]

In the legacy code the method written below was followed:

<?php

namespace App\Http\Controllers;

use App\User;
use Illuminate\Http\Request;

class UserController extends Controller
{
    public function index(Request $request)
    {
        $users = User::where('is_active', true);

        if ($request->has('age_more_than')) {
            $users->where('age', '>', $request->age_more_than);
        }

        if ($request->has('gender')) {
            $users->where('gender', $request->gender);
        }

        if ($request->has('has_published_post')) {
            $users->where(function ($query) use ($request) {
                $query->whereHas('posts', function ($query) use ($request) {
                    $query->where('is_published', $request->has_published_post);
                });
            });
        }

        return $users->get();
    }
}

But the new method with EloquentBuilder follows the steps below:

<?php

namespace App\Http\Controllers;

use App\User;
use EloquentBuilder;
use Illuminate\Http\Request;

class UserController extends Controller
{
    public function index(Request $request)
    {
        $users = EloquentBuilder::to(User::class, $request->all());

        return $users->get();
    }
}

Note: It's recommended validates the incoming requests before sending to filters.

Installation

• Laravel
• Lumen

Laravel

You can install the package via composer:

composer require mohammad-fouladgar/eloquent-builder

Laravel 5.5 uses Package Auto-Discovery, so you are not required to add ServiceProvider manually.

Laravel <= 5.4.x

If you don't use Auto-Discovery, add the ServiceProvider to the providers array in config/app.php file

'providers' => [
  /*
   * Package Service Providers...
   */
  Fouladgar\EloquentBuilder\ServiceProvider::class,
],

And add the facade to your config/app.php file

/*
|--------------------------------------------------------------------------
| Class Aliases
|--------------------------------------------------------------------------
*/
'aliases' => [
    "EloquentBuilder" => Fouladgar\EloquentBuilder\Facade::class,
]

Lumen

You can install the package via composer:

composer require mohammad-fouladgar/eloquent-builder

For Lumen, add the LumenServiceProvider to the bootstrap/app.php file

/*
|--------------------------------------------------------------------------
| Register Service Providers...
|--------------------------------------------------------------------------
*/

$app->register(\Fouladgar\EloquentBuilder\LumenServiceProvider::class);

For using the facade you have to uncomment the line $app->withFacades(); in the bootstrap/app.php file

After uncommenting this line you have the EloquentBuilder facade enabled

$app->withFacades();

Publish the configuration file

php artisan eloquent-builder:publish

and add the configuration to the bootstrap/app.php file

$app->configure('eloquent-builder');
...
$app->register(\Fouladgar\EloquentBuilder\LumenServiceProvider::class);

Important : this needs to be before the registration of the service provider.

Default Filters Namespace

The default namespace for all filters is App\EloquentFilters\ with the base name of the Model.

For example:

Suppose we have a User model with an AgeMoreThan filter.As a result, the namespace filter must be as follows:

App\EloquentFilters\User\AgeMoreThanFilter

With Config file

You can optionally publish the config file with:

php artisan vendor:publish --provider="Fouladgar\EloquentBuilder\ServiceProvider" --tag="config"

And set the namespace for your model filters which will reside in:

return [
    /*
     |--------------------------------------------------------------------------
     | Eloquent Filter Settings
     |--------------------------------------------------------------------------
     |
     | This is the namespace all you Eloquent Model Filters will reside
     |
     */
    'namespace' => 'App\\EloquentFilters\\',
];

Define a Filter

Writing a filter is simple. Define a class that implements the Fouladgar\EloquentBuilder\Support\Foundation\Contracts\IFilter interface. This interface requires you to implement one method: apply. The apply method may add where constraints to the query as needed:

<?php

namespace App\EloquentFilters\User;

use Fouladgar\EloquentBuilder\Support\Foundation\Contracts\IFilter as Filter;
use Illuminate\Database\Eloquent\Builder;

class AgeMoreThanFilter implements Filter
{
    /**
     * Apply the age condition to the query.
     *
     * @param Builder $builder
     * @param mixed   $value
     *
     * @return Builder
     */
    public function apply(Builder $builder, $value): Builder
    {
        return $builder->where('age', '>', $value);
    }
}

Ignore Filters on null value

Filter parameters are ignored if contain empty values or null.

Suppose we have a request something like:

//Get api/user/search?name&gender=null&age_more_than=''&published_post=true

// Request result will be:
$filters = [
    'published_post'  => true
];

Only the "published_post" filter will be applied on your query.

Work with existing queries

You may also want to work with existing queries. For example, consider the following code:

<?php

namespace App\Http\Controllers;

use App\User;
use EloquentBuilder;
use Illuminate\Http\Request;

class UserController extends Controller
{
    public function index(Request $request)
    {
        $query = User::where('is_active', true);
        $users = EloquentBuilder::to($query, $request->all())
            ->where('city', 'london')
            ->paginate();

        return $users;
    }
}

Use as Dependency Injection

Suppose you want use the EloquentBuilder as DependencyInjection in a Repository.

Let's have an example.We have a sample UserRepository as follows:

<?php

namespace App\Repositories;

use App\User;
use Fouladgar\EloquentBuilder\EloquentBuilder;

class UserRepository extends BaseRepository
{
    
    public function __construct(EloquentBuilder $eloquentBuilder)
    {
        $this->eloquentBuilder = $eloquentBuilder;
        $this->makeModel();
    }

    public function makeModel()
    {
        return $this->setModel($this->model());
    }
    
    public function setModel($model)
    {
        $this->model = app()->make($model);

        return $this;
    }
    
    public function model()
    {
        return User::class;
    }
    
    public function all($columns = ['*'])
    {
        return $this->model->get($columns);
    }

    // other methods ...

    public function filters(array $filters)
    {
        $this->model = $this->eloquentBuilder->to($this->model(), $filters);

        return $this;
    }
}

The filters method applies the requested filters to the query by using EloquentBuilder injected.

Injecting The Repository

Now,we can simply "type-hint" it in the constructor of our UserController:

<?php

namespace App\Http\Controllers;

use App\Repositories\UserRepository;
use Illuminate\Http\Request;

class UserController extends Controller
{

    protected $users;

    public function __construct(UserRepository $users)
    {
        $this->users = $users;
    }

    public function index(Request $request)
    {
        return $this->users->filters($request->all())->get();
    }
}
