Can you list the existing types of relationships between models in Laravel?

In Laravel, the following are the main types of relationships between models:

• One to One — one record in a table is related to one record in another.
• One to Many — one record is related to many records in another table.
• Many to Many — many records are related to many records in another table through a pivot table.
• Polymorphic Relations — allow a model to belong to more than one other model on a single association.

Example of a "One to Many" relationship:

class Post extends Model {
    public function comments() {
        return $this->hasMany(Comment::class);
    }
}

class Comment extends Model {
    public function post() {
        return $this->belongsTo(Post::class);
    }
}

These relationships make it convenient to work with data and build complex queries using Eloquent ORM.
