use scope method in blade

I have two tables: revisions_intervals and revisions. Revisions_intervals has many revisions and one revision belongs to one revisions_intervals. So, i my revision model:

public function revision_interval() {
    return $this->belongsTo('App\Revision_interval');
}

and in my revision_interval model:

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

I have view "index" for revisions intervals, where for each one I want to show how many relations are related to specified revision interval. In my "index" blade:

@foreach($revision_intervals as $interval)
                <tr>
                    <td> 
                         /
                         
                    </td>
                </tr>
@endforeach

This "past()" method should be "scope" method for revision model, but this doesnt work. How to do it? ( Select specified revisions for collection )

I have "scopePast" method in my revision model:

public function scopePast($query) {
    $date = \Carbon\Carbon::now()->format('Y-m-d');
    $query->where('date_of_revision', '>', $date);
}
