Problem fetching values to child table after update

1

Hi ,

I was using the below code to fetch values into a child table , it was working perfectly but after the update the below code is not working , please help

cur_frm.add_fetch('grade','percnt_carbon_min','percnt_carbon_min');
{
cur_frm.add_fetch('percnt_carbon_min','percnt_carbon_min');

frappe.ui.form.on("Customer TDC", "refresh", function(frm, doctype, name) 
	{
		cur_frm.get_field("percnt_carbon_min").get_query = function(doc, cdt, cdn) 
		{
			var item = frappe.get_doc(cdt, cdn);
			var c = " ";
            if (item.grade) c=item.grade ;
            return { filters: {'grade': c}} 
		}
	}
);		
}

Is any function depreciated in the update ?

Thank you @makarand_b for responding , I am not getting any error in the console log ?

check the add_fetch method syntax, You are missing target_fieldname

add_fetch(link_fieldname, source_fieldname, target_fieldname)

Thanks, Makarand

frappe.ui.form.on('Purchase Order Item', 'grade', function(frm, cdt, cdn){
    frappe.call({
        'method': 'frappe.client.get_value',
        'args': {
            'doctype': 'Grade',
            'filters': [
                ['Grade', 'grade', '=', locals[cdt][cdn].grade]
            ],
           'fieldname':'percnt_carbon_min'
        },
        'callback': function(r){
            frappe.mode.set_value(cdt, cdn, 'percnt_carbon_min', r.message.percnt_carbon_min);
        }
refresh_field("percnt_carbon_min");
    });
});

Hi @Muthu,

it should be frappe.model.set_value(doctype, docname, fieldname, value)
