Make Read Only After Saving
Use the method cur_frm.set_df_property
to update the field's display.
In this script we also use the __islocal
property of the DocType to check if the
document has been saved at least once or is never saved. If __islocal
is 1
,
then the document has never been saved.
frappe.ui.form.on("MyDocType", "refresh", function(frm) {
// use the is_new method of frm, to check if the doc is saved or not
frm.set_df_property("myfield", "read_only", frm.is_new() ? 0 : 1);
}
