How to generate destroy path for delete method when there's no destroy path on rails

I was trying to build a simple rails app with create, edit, delete method in, but when I checked on the routes the destroy method seems to missing as below;

DELETE /products/:id(.:format)  products#destroy``` 
where the delete path is missing whereas my routes file has contains . 
```  resources :products, only: [:index, :show, :new, :create, :destroy, :edit] ```

my question is:
I was wondering how do I do to create the missing destroy path and why is the reason even if i did resources on products i have still not get product delete path.

thank you so much!
