Why frappe.get_prev_route()
client-side method just work on browser console and on an app that returns null?
Can you post an example of where this might be useful. I am currently trying to write a custom script that has to take values from the previous DocType and this might be useful. Were you able to get it to work?
I was doing it wrong, if someone need an example how to do it, here is:
frappe.ui.form.on('DocType', {
trigger: function (frm) {
// Get document previous route
prev_route = frappe.get_prev_route();
prev_doctype = prev_route[1];
prev_docname = prev_route[2];
prev_doc = frappe.get_doc(prev_doctype, prev_docname);
},
});
