强制唯一规则忽略给定ID

Question

In my controller i was trying to update my product, product name here is unique and here i wanted to update only price. so name will be as it but as i defined name as a unique field though i haven't changed the name it throws me unique name validation error as this name already exist. How do i ignore that validation request when i don't update the unique value?

public function update(Request $request, $id)
        {
           $this->validate($request, [              
            'name'=> 'required|unique:products,'.$id,
            ]);        
            $product= Product::find($id);
            $product->name = Input::get('name');
            $product->price = Input::get('price'); 
            $product->save();
       }

Change it to:

'name'=> 'required|unique:products,name' . $id,
