Laravel: how to write query without a target - php

Question

Is it possible to create a query first and then assign it to a select?
For Example
$queryWithoutTarget = new Builder();
$queryWithoutTarget->where('x','y')->whereNull('z');
$workersQuery = Worker::select();
// I know this is Totally wrong, because queryWithoutTarget is not a parameter of $workersQuery
$workersQuery = $workersQuery->queryWithoutTarget;
I'm trying to encapsulate the query in functions and then execute them to any model or table

Answer 1

No, first you use $queryWithoutTarget as a variable (at the first and third row), then you use it as a function (at the 8th row ({...}->queryWithoutTarget)
Edit: If you override the Builder class then it may be possible. Open has maybe endless possibilities. But it's up to you to make overrides instead of additional lines in the controller

Answer 2

Use a scope. Scope is just a convenience method you can add to your model which encapsulates the syntax used to execute a query
Create your scope trait
namespace App\Models\Worker\Traits;
/**
* Class WorkerScope.
*/
trait WorkerScope
{
/**
* #param $query
*
* #return mixed
*/
public function scopeActive($query)
{
return $query->where('x','y')->whereNull('z');
}
}
Implement your scope on model
use App\Models\Worker\Traits\WorkerScope;
/**
* Class Worker.
*/
class Worker extends Model
{
use WorkerScope;
...
}
With the scope defined, you can execute it like
$workersQuery = Worker::active()->get();
