# Introduction

This analyzer scans your application code to ensure that your code does not refer to model relations that do not exist.

If your code refers to any relations that do not exist, then it may result in runtime exceptions.

As an example, consider the following code:

class BookController extends Controller
    public function getBooks($title)
        return Book::where('title', $title)->whereHas('author')->get();

class Book extends Model
    public function authors(): HasMany
        return $this->hasMany(BananaModel::class);

The above code refers to the author relation in the Book model, however, the model contains the authors relation instead.
