cascade filter

[Ari Sobel]

Hi to all,

In jam-py - edit form, can I make like a cascade filter ?

For example, when I filter one field, to get other filed (lookup field) to be filtered with a specific parameter?

thanks and regards

If you c/p this code into Demo/Invoices:
https://jampy-docs-v7.readthedocs.io/en/latest/refs/client/item/at_filters.html
like:

function on_view_form_created(item) {
    invoices_filters(item);   

....

you'll be able to see in the console which one is active!

So, if you add this code:

function on_view_form_created(item) {

item.invoice_table.master_applies = true;

set_paid_btn(item);

var date_today = new Date(new Date().setYear(new Date().getFullYear()));

item.filters.invoicedate2.value = date_today;

if (date_today) {

item.filters.paid.value = false;

}

invoices_filters(item);

console.log(item.filters.invoicedate2.value)

}

The console will tell:
From null 
to 2025-09-08 
Customer null
Paid 0
2025-09-08

See how to do it?
