How can i save fields from M:N relation? about directus-extension-computed-interface HOT 3 CLOSED

Hello @hermesalvesbr ,
For now, the template cannot parse relational fields but we can see this is an important feature. If I'm not mistaken, you want to aggregate the total price of all products. So I imagine the template can be as follow:

{{ SUM(DOT_PRODUCT(products.price, products.quantity)) }}

OR in each product, you can create a field (let's call it amount) that calculates {{ MULTIPLY(price, quantity) }} first, then sum them up in the total field with {{ SUM(products.amount) }}.

In either case, we would need to update our extension to parse relational fields. Although we cannot assure about the timeline, we are thinking about it so let's wait for our news.

Thanks @Guiqft for this partnership! Maybe i found a bug, when use with readonly input fields.
