Child doctype field problem

i need how to change a filed type on child doctype to mandatory based on selection or check box and also how to change it to read only on save

You can use these function for your purpose:

to make field mandatory: frm.toggle_reqd(fnames, mandatory)
to make field read only : frm.toggle_enable(fnames, enable)

it does not work :frowning:

could you share your code

Dear @Mohammed_Redha

i use this script to make field margin mandatory when select Final LG from filed type but it’s not working

ur_frm.cscript.custom_mandatory_filed = function(doc){
cur_frm.set_df_property(“margin”, “reqd”, doc.type==“LG Final”);}

could you please post the correct code

@Alaa_Badri colud you share complete code to help you

Thanks Mohamed For your quick response

this below script is working fine but only make margin filed mandatory when click save not immediate change filed color to red like for example in payment entry with payment mode cheque

cur_frm.cscript.custom_validate= function(doc){
cur_frm.set_df_property(“margin”, “reqd”,doc.type==“LG Final”);}


frappe.ui.form.on([DocType], {
[trigger]: function(frm) {

in your case

frappe.ui.form.on(‘Payment Entry’, {
custom_mandatory_filed: function(frm) {
frm.set_df_propertyset_df_property(“margin”, “reqd”,frm.doc.type==“LG Final”);

please look at this link :

SyntaxError: Invalid or unexpected token

sorry, try agin

frappe.ui.form.on('Payment Entry', {
	custom_mandatory_filed: function(frm) {
		frm.set_df_propertyset_df_property('margin', 'reqd',frm.doc.type=='LG Final');

Thanks Mohamed
