Как обновить уникальное поле?

Здравствуйте, в контроллере при редактировании продукта делаю так

public function editRequestProduct(Request $request, int $id){
        $validator = Validator::make($request->all(), [
            'title' => 'required|string|min:4|max:25',
            'slug' => array(
                'required',
                'string',
                'min:4',
                'max:25',
                'unique:products',
                'regex:/^[a-z0-9а-яё-]+$/u',
            ),
            'excerpt' => 'required|string|min:4|max:100',
            'content' => 'required|string|min:4|max:300',
            'descrtitle' => 'required|string|min:4|max:100',
            'descrtext' => 'required|string|min:4|max:300',
            'descr' => 'required|string|min:4|max:300',
            'regular_price' => array(
                'required',
                'regex:/\d+/',
            ),
            'discount' => array(
                'required',
                'min:0',
                'max:100',
                'regex:/^\d+(\.\d{1,2})?$/',
            ),
            'image' => 'mimes:jpeg,jpg,png,gif|max:10000',
            'tab_bg' => 'mimes:jpeg,jpg,png,gif|max:10000',
        ]);

        if($validator->fails()){
            return back()->withErrors($validator)->withInput();
        }

        $objProducts = Products::find($id);
        if(!$objProducts){
            return abort('404');
        }

        $is_reccomended = $request->has('is_reccomended') ? true : false;

        $image = ImageDNK::save($request, 'image');
        $tab_bg = ImageDNK::save($request, 'tab_bg');


        $objProducts->title = $request->input('title');
        $objProducts->slug = $request->input('slug');
        $objProducts->excerpt = $request->input('excerpt');
        $objProducts->content = $request->input('content');
        $objProducts->descrtitle = $request->input('descrtitle');
        $objProducts->descrtext = $request->input('descrtext');
        $objProducts->descr = $request->input('descr');
        $objProducts->regular_price = $request->input('regular_price');
        $objProducts->sale_price = $request->input('sale_price');
        $objProducts->discount = $request->input('discount');
        $objProducts->currency = $request->input('currency');
        $objProducts->image = $image;
        $objProducts->is_reccomended = $is_reccomended;
        $objProducts->product_description_tab_content = $request->input('product_description_tab_content');
        $objProducts->product_ingredients_tab_content = $request->input('product_ingredients_tab_content');
        $objProducts->product_usage_tab_content = $request->input('product_usage_tab_content');
        $objProducts->tab_bg = $tab_bg;

        if(!$objProducts->save()){
            return back()->with('error', 'Товар не изменен. Попробуйте ещё раз');
        }

        $hasCategory = $request->input('product_category') != 0;

        if($hasCategory){
            $objCatsRels = new CategoriesRelationship();
            $objCatsRels = $objCatsRels->create([
                'object_id' => $id,
                'category_id' => $request->input('product_category'),
            ]);
        }

        if($objProducts && (!$hasCategory || $objCatsRels)){
            return back()->with('success', trans('messages.products.successUpdated'));
        }

    }

Если не убрать проверку на уникальность slug то существующий slug не пройдет проверку. Как поменять slug но при этом проверить что у других товаров нет такого slug?

Спасибо.
