Laravel collection filter using scopes - laravel

Question

I have the following table:
Active
id
starts_at
ends_at
I would like to get all the actives daily, comparing the two dates starts_at and ends_at and get the diff in days, like this example:
Route::get('test', function(){
$dailyActives = \App\Models\Active::all()->filter(function ($active) {
return $active->starts_at->diffInDays($active->ends_at) >= 1 && $active->starts_at->diffInDays($active->ends_at) <= 3;
});
dd($dailyActives);
});
it works 100%.
But I would like to reuse this code as I have more modes like Daily, Weekly, Month.
My idea was creating a scope in the model but I can't use filter as $query is not a collection.
I tried the following code:
/**
* Scope a query to only include daily actives.
*
* #param \Illuminate\Database\Eloquent\Builder $query
* #return \Illuminate\Database\Eloquent\Builder
*/
public function scopeDaily($query)
{
$query->filter(function ($active) {
if($active->starts_at->diffInDays($active->ends_at) >= 1 && $active->starts_at->diffInDays($active->ends_at) <=3) {
return true;
}
});
}
So can someone recommend me the best way to do that? Maybe using scope and how? or creating a reusable class, where just calling the Active::daily()->get() I get all the actives daily, for example.
Many thanks in advance!

You do not need to use a filter. Use scop like this $dailyActives = \App\Models\Active::interval('weekly')->get();
public function scopeInterval($query, $interval = 'daily')
{
// daily
$dateBetween = [now()->startOfDay(), now()->endOfDay()];
if($interval === 'weekly'){
$dateBetween = [now()->startOfWeek(), now()->endOfWeek()];
}
elseif($interval === 'month'){
$dateBetween = [now()->startOfMonth(), now()->endOfMonth()];
}
$query->whereBetween('created_at', $dateBetween);
return $query;
}
