Whitelisting Document methods

If you were accessing any document methods using one of the following constructs, the method needs to be whitelisted in the doctype class. Additionally, if you were setting document methods as options for Button fields, those will need to be whitelisted as well.

frm.call("my_method")
// or
frappe.call({
    doc: frm.doc,
    method: "my_method"
})

class ToDo:
+   frappe.whitelist()
    def my_method(self):
        pass
