In products table I have fields like

```
id   product_name   product_value   quantity    status
1     abc             10000           50        received
2     efg             5000            15        shipment
3     hij             850             100       received
4     klm             7000            20        shipment
5     nop             350             50        received

```

I can select multiple rows at a time. And here I selected `id=2,4` and need to change the `status='received'`. How to do multiple update at single time in rails?
