    public function store(StoreRequest $request)

The parameter $request is not used and could be removed.

    {
        return parent::storeCrud();

It seems like you call parent on a different method (storeCrud() instead of store()). Are you sure this is correct? If so, you might want to change this to $this->storeCrud().

    }

    public function update(UpdateRequest $request)

The parameter $request is not used and could be removed.

    {
        return parent::updateCrud();
    }
}
