How to add selected items in a list to a database?

Question

Python

Hey!
There is a table of product names that can be ticked off for the order. How can I immediately send a request in a batch and process it?

| + | 1 | Bread |
| - | 2 | Sausage |
| - | 3 | Potato |
| + | 4 | cabbage |

After clicking on the "add" button, I need to send an Ajax request to add "Bread" and "Cabbage" to the database table
