How to make correctly polymorphic connections and relationships?

Question

Laravel

There are 3 models: Document, Status, ApprovalAttempt.

documents
    id - integer
    name - string

statuses
    id - integer
    approval_attempt_id - integer (foreign key)

approval_attempts
    id - integer
    approvable_type - string
    approvable_id - integer

In approval_attempts I use the fields to create a Laravel polymorphic relationship.

How to make it possible to call a property in the Document model ->statusesand get all document statuses (document ID in approval_attempts, ID ApprovalAttempt in the statuses table).

Like this:

public function statuses()
{
    return $this->approvalAttempts()->statuses();
}

But it's probably too sugary and doesn't work. How to be?

Look towards hasMany and belongsTo. Well, the documentation in general https://laravel.com/docs/7.x/eloquent-relationships
