Call to undefined method error

Get the following error. Not sure how to fix it. I may have things in the wrong areas as this is my first laravel project so I am not sure if I am doing it correctly.

BadMethodCallException in Builder.php line 1994:
Call to undefined method Illuminate\Database\Query\Builder::getLewpByName()
