Locate function call in laravel 5.8 - php

Question

Hello I'm new to laravel but not php. I was tasked to optimized some backend query and needed some help on locating where the model function "getPackagesSoldAttribute" is being called here. I don't see in the controller that this function is being called like ProEvent::getPackagesSoldAttribute for example.
So my view is showing the return of the function. Any idea how did laravel called this function? I also did check PHP DebugBar and I saw the query the getPackagesSoldAttribute function used.
I also created a script that would locate the string "getPackagesSoldAttribute" but could only find one and that is in the model.
Route::get('{organiser_id}/pro_events/{filter?}', [
'as' => 'showOrganiserProEvents',
'uses' => 'OrganiserProEventsController#showOrganiserProEvents',
]);
This is the controller function called by route.
public function showOrganiserProEvents(Request $request, $organiser_id, $filter = null, $listView = null)
{
$add_on_check = \App\Models\OrganisationAddon::where('org_id', $organiser_id)->first();
$edit_create_enable = "";
$delete_enable = "";
if( !empty($add_on_check) ){
$add_ons = json_decode($add_on_check->add_ons);
$edit_create_enable = !empty($add_ons->enable_create_edit_event)?"1":"";
$delete_enable = !empty($add_ons->enable_delete_event)?"1":"";
}
$organiser = Organiser::find($organiser_id);
$allowed_sorts = ['created_at', 'event_date', 'title'];
$searchQuery = $request->get('q');
$sort_by = (in_array($request->get('sort_by'), $allowed_sorts) ? $request->get('sort_by') : 'event_date');
$eventListView = empty($request->get('view_list_by')) ? 'grid' : $request->get('view_list_by');
if($listView){
$eventListView = $listView;
}
if($filter == null){
$filter = "live";
}
if( $searchQuery ){
$the_event = ProEvent::where('title', 'like', '%' . $searchQuery . '%');
if($sort_by == 'event_date'){
$the_event->orderBy($sort_by, 'asc');
} else {
$the_event->orderBy($sort_by, 'desc');
}
$the_event->where('organiser_id', '=', $organiser_id);
if( $filter == "templates"){
$the_event->where(function($query){
$query->where('event_status', 'template');
$query->orWhere('is_master', 1);
});
}else if( $filter == "live" ){
$the_event->where('event_status', "live");
}else if( $filter == "past" ){
$the_event->where(function($query){
$query->where('event_status', 'past');
$query->orWhere('event_date', '<', Carbon::now());
});
}else if( $filter == "testing" ){
$the_event->where(function($query){
$query->where('event_status', 'testing');
$query->orWhere('event_status', 'pos_testing');
});
}else if( $filter == "abandoned" ){
$the_event->where('event_status', "abandoned");
}
$events = $the_event->get();
}else{

See Eloquent: Mutators. getPackagesSoldAttribute is an "Accessor" method. Basically, you wont see getPackagesSoldAttribute called directly, instead, when the code calls $model->packages_sold, in the background, laravel will actually call $model->getPackagesSoldAttribute dynamically and return its response as that value.
For example, if you wanted to debug or test this method, you might do something like:
$event = ProEvent::find($someId);
$packagesSold = $event->packages_sold; // this line will call the `getPackagesSoldAttribute` and set `$packagesSold` to the value it returns.
Also of note:
The model here also defines an appends property with packages_sold
protected $appends = array('packages_sold', 'bundles_sold');
This will cause the packages_sold property to be automatically filled by the method in question any time the model is represented as an array or serialized. see also
