Hi All,

We will look at example of laravel with max eloquent. So, let's follow few step to create example of laravel withmin.

Here i will give you very simple example of how to use withMin(), withMax() and withAvg() with laravel relationship eloquent. we will create Category and Product and how you can add relationship and get it.

you can easily use withMin(), withMax() and withAvg() with laravel 6, laravel 7 and laravel 8 version.

Let's see example with output:

Category Model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Category extends Model

{

use HasFactory;

/**

* Get the comments for the blog post.

*/

public function products()

{

return $this->hasMany(Product::class);

}

}

Product Model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Product extends Model

{

use HasFactory;

protected $fillable = [

'name', 'price'

];

}

withMin() Example:

<?php

namespace App\Http\Controllers;

use App\Models\Category;

class SignaturePadController extends Controller

{

/**

* Write code on Method

*

* @return response()

*/

public function index()

{

$categories = Category::select("id", "name")

->withMin('products', 'price')

->get()

->toArray();

dd($categories);

}

}

Output:

Array

(

[0] => Array

(

[id] => 1

[name] => Mobile

[products_min_price] => 100

)

[1] => Array

(

[id] => 2

[name] => Laptop

[products_min_price] => 200

)

withMax() Example:

<?php

namespace App\Http\Controllers;

use App\Models\Category;

class SignaturePadController extends Controller

{

/**

* Write code on Method

*

* @return response()

*/

public function index()

{

$categories = Category::select("id", "name")

->withMax('products', 'price')

->get()

->toArray();

dd($categories);

}

}

Output:

Array

(

[0] => Array

(

[id] => 1

[name] => Mobile

[products_max_price] => 120

)

[1] => Array

(

[id] => 2

[name] => Laptop

[products_max_price] => 210

)

)

withAvg() Example:

<?php

namespace App\Http\Controllers;

use App\Models\Category;

class SignaturePadController extends Controller

{

/**

* Write code on Method

*

* @return response()

*/

public function index()

{

$categories = Category::select("id", "name")

->withAvg('products', 'price')

->get()

->toArray();

dd($categories);

}

}

Output:

Array

[0] => Array

(

[id] => 1

[name] => Mobile

[products_avg_price] => 110.0000

)

[1] => Array
