Nested Editor

Hello,

I built a nested editor one for products and another one for prices. the relationship is one-to-many. 1 product can have multiple prices. everything is working fine but when selecting the product and editor open I need to get the prices for the selected products.

When I replace this one for example

$q->where('prices.product_id','products.id');

with

$q->where('prices.product_id','1');

I got the correct prices but this is a fixed value. How can I assign products.id in a dynamic when the row is selected and the editor is open?

and also, when I edit the price row in the nested editor, the new editor opens but it's empty. it should have the values of the selected price.

**prices.php controller. **
