I have currently studying the eloquent orm relationship in laravel, right now I just reading the documentation of laravel how to differentiate the One to One, One to Many and Many to Many. Today I create products and product categories. however I have a single question why does the product categories column in the table is not included to the output: I will share to you guys the sample model that I created today.

I have here product categories model:

    <?php



namespace App;



use Illuminate\Database\Eloquent\Model;



class product_category extends Model

{

    //

    // protected $table = 'product_categories';

    public function getProductsRelation() {

        return $this->hasMany(product::class,'product_categorie_id','id');

    }

}

For my product model:

    <?php



namespace App;



use Illuminate\Database\Eloquent\Model;



class product extends Model

{

    //

    protected $table = 'products';

}

My Output:

Why this column not included to the output:

---

My Answer:
php

namespace App;

use Illuminate\Database\Eloquent\Model;

class ProductCategory extends Model
{
protected $table = 'product_categories';

public function products()
{
return $this->hasMany('App\Product');
}
}


In the above code, you have defined a `ProductCategory` model with a `hasMany` relationship to the `Product` model. This means that a product category can have multiple products associated with it.

If you are not seeing the product categories column in the output, it could be due to how you are retrieving the data. Make sure that you are eager loading the product categories when querying the products. Here is an example of how you can do this:

php
$products = Product::with('productCategory')->get();

foreach ($products as $product) {
echo $product->name . ' - ' . $product->productCategory->name . '
';
}


In the above code, we are eager loading the `productCategory` relationship when querying the products. This will ensure that the product categories are included in the output.

If you are still facing issues with the output, please provide more details on how you are querying the data and we can help you further.
