Answer 1

Try this one. It works. Add this to your model.

Library model

public function store()
    {
        return $this->belongsTo(Store::class, 'store_id', 'id');
    }

Store model

 public function libraries()
    {
        return $this->hasMany(Library::class);
    }

example code.

 $store = Store::find(1);
 dd($store->libraries);

Because in this case a store has many libraries, the Store model has a libraries() function. Refer to last line of James' answer for more information on this standard.
