Read One-to-Many basics & try with this code as you want

Go throw laravel documentation to read about it & many more blog

First you need to clone this and save .env.example as .env and setup your environment or just change the database configure

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your-database-name
DB_USERNAME=your-database-user-name
DB_PASSWORD=your-database-password(if have)

Now just run some command on terminal one by one

composer install
php artisan migrate
php artisan serve

As I have said this is One to Many relationship. // Imagine part

• Example1: A User can have many posts
• Example2: Student can have many Books
• Example3: Office can have many employees
• Example3: Owner can have many cars

So I have just created Two model

• User
• Post

User Model are relation with hasOne

    public function posts()
    {
        return $this->hasMany(Post::class);
    }

Posts Model are relation with belongsTo

    public function user()
    {
        return $this->belongsTo(User::class);
    }

    // You can save return $this->belongsTo(User::class, 'user_id'); relation column name if you didn't follow the naming convention 

And controller code are depend's on condition what I need. So you can got throw the controllers method.

if you have Postman/any software like that please import One-to-Many.postman_collection.json file either call
