WhereBetween not found on eloquent hasmany - laravel

Question

Using Laravel 5. I have a model Property, that has many Weeks available to it. This is the Property Model.
<?php namespace App\Models;
use Illuminate\Database\Eloquent\Model;
/**
* #property mixed week
*/
class Property extends Model
{
public function week()
{
return $this->hasMany('App\Models\Week', 'PropertyID', 'PropertyID');
}
}
I am trying to use WhereBetween on a hasMany relation of an object using the WhereBetween method. This is the error I get though.
Method 'WhereBetween' not found in class 'illumainate\Database\Eloquent\Relations\HasMany.
list($from, $to) = $params->get('range');
$week = $property->week()
->whereBetween('WeekDate', array($from, $to))
->get();
The same error occurs if I try WhereRaw instead of WhereBetween. hasMany class doesn't have WhereRaw or WhereBetween. Is there a way around this?

I had a similar issue in Laravel 5.2 with the following code:
$events = Events::whereBetween('start', array($start, $end))
->whereBetween('end', array($start, $end))
->get();
This throws an error like:
Call to undefined method App\Events::whereBetween()
Somehow in Laravel 5.0+ I could not use whereBeetween directly on the model. But in the API documentation whereBetween is still listed as function of the DB class (see here). By replacing the model with the DB class we can fix it:
use DB;
...
$events = DB::table('events')
->whereBetween('start', array($start, $end))
->whereBetween('end', array($start, $end))
->get();
