Create Migrations:

Now we have to create migration of "portfolios" and "portfolioCategories" table. so let's create like as below:

portfolios table migration:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreatePortfoliosTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('portfolios', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->string('sub_title');
            $table->integer('portfolio_category_id');
            $table->text('description');
            $table->string('image');
            $table->string('client');
            $table->date('date');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('portfolios');
    }
}
?>

portfolioCategories table migration:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreatePortfolioCategoriesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('portfolio_categories', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('portfolio_categories');
    }
}
?>
Create Models:

Here, we will create Portfolio and PortfolioCategory table model. we will also use "hasOne()" for relationship of both model.

Portfolio Model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Portfolio extends Model
{
    use HasFactory;

    public $table = 'portfolios';
   
	public $fillable = ['title','sub_title','portfolio_category_id','description'];

	/**
	    * Write code on Method
	    *
	    * @return response()
	*/
	public function PortfolioCategory(){
        return $this->hasOne(PortfolioCategory::class, 'id', 'portfolio_category_id');
	}
}
?>

PortfolioCategory Model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Portfolio_Category extends Model
{
    use HasFactory;

    public $table = 'portfolio_categories';
   
	public $fillable = ['name'];
}
?>

Retrieve Records:

$portfolioCategory = Portfolio::find(1)->portfolioCategory;
dd($portfolioCategory);
$portfolio = PortfolioCategory::find(1)->portfolio;
dd($portfolio);

Create Records:

$portfolio = Portfolio::find(1);
 
$portfolioCategory = new PortfolioCategory;
$portfolioCategory->portfolioCategory = '9429343852';
 
$portfolio->portfolioCategory()->save($portfolioCategory);
$portfolioCategory = PortfolioCategory::find(1);
 
$portfolio = Portfolio::find(10);
 
$portfolioCategory->portfolio()->associate($portfolio)->save();

It will help you....
