How to validate a unique field in Larvel 5?

Question

Laravel

Hello! there is the following record update code

public function update(Request $request, $id)
    {
        $page = Page::findOrFail($id);
        $this->validate($request, [
            'title' => 'required',
            'description' => 'required',
            'slug' => 'required|unique:pages',
            'status' => 'required',
            'type' => 'required',
        ]);
        $input = $request->all();
        $page->fill($input)->save();
        \Session::flash('page_updated', 'Страница обновлена!');

        return redirect()->route('adminPages');
    }

It turns out that when a record is created, a slug is formed, and when the same record is updated, it says that such a slug is already used, although it is the same and there are no identical ones in the database. How to be?

We read here laravel.com/docs/5.1/validation#rule-unique
Specifically, the section " Forcing A Unique Rule To Ignore A Given ID "
That is, in this case it will be like this:

'slug' => 'required|unique:pages,slug,' . $page->id,
