nested query with laravel model - laravel

Question

I am writing a nested query with Laravel.
Namely First, the Truck information is drawn, then I list the data of the vehicle with "truck_history", there is no problem until here, but I want to show the information of the invoice belonging to the "invoice_id" in truck_history. but I couldn't understand how to query, I want to do it in the model, is this possible? If possible, how will it be done?
"ID" COLUMN IN INVOICE TABLE AND "invoice_id" in "InvoiceDetail" match.
TruckController
public function getTruck($id)
{
$truck = Truck::with(['truckHistory'])->find($id);
return $truck;
}
Truck Model
protected $appends = ['company_name'];
public function companys()
{
return $this->belongsTo(Contact::class, 'company_id', 'id');
}
public function getCompanyNameAttribute()
{
return $this->companys()->first()->name;
}
public function truckHistory(){
return $this->hasMany(InvoiceDetail::class,'plate_no','plate');
}

Answer 1

So you can add another relationship in the InvoiceDetail::class and add in the truck history.
try something like this:
public function truckHistory(){
return $this->hasMany(InvoiceDetail::class,'plate_no','plate')->with('Invoice');
}

Answer 2

Simply add the following relations (if you don't already have them):
Invoice model :
public function truckHistory()
{
return $this->hasOne(InvoiceDetail::class);
}
InvoiceDetail model :
public function invoice()
{
return $this->belongsTo(Invoice::class);
}
And you can get the relation invoice of the relation truckHistory adding a point as separator :
public function getTruck($id)
{
$truck = Truck::with(['truckHistory.invoice'])->find($id);
return $truck;
}
