Filtering child listView based on information from parent

💬 Queries and Resources

Imagine I have database tables:

customers, with columns customerId, firstName, lastName
products, with columns productId, name, description
orders, with columns customerId, productId, quantity

Now I have a listView of customers (customerListView), and within that a nested listView (orderListView) with information about the products ordered by that customer.

Based on the section on nesting in Build custom views using repeatable components | Retool Docs I thought I'd be able to write backing queries:

select * from customers

and

select p.productId, p.name, p.description, o.quantity 
from orders o 
inner join products p
on o.productId = p.productId
where o.customerId = {{ customerListView.item.customerId }}

However this doesn't seem to work. The autocomplete doesn't even suggest customerListView.item . Am I doing something wrong? Is there some other way to achieve this?

Hello @Stereotomy

access customer data within a nested listView in Retool, use {{ customerListView.data.item.customerId }} in the inner listView's backing query. This will correctly fetch orders for the selected customer.

yes, .item will reference the current element from the parent listView so you should be able to filter by that value properly
