How to Automatically Check "Public" Checkbox in Event When Created from Opportunity?

Hi everyone,

I’m working on customizing the
Event creation flow inside the Opportunity doctype. Under the Activities tab, when I click “New Event”, I want the “Public” checkbox to be automatically checked.

My use case:

  • The Event is being created from inside the Opportunity screen (reference_type = “Opportunity”)
  • I want the “Public” checkbox to be checks Always

Is there a clean way to achieve this using Client Script?

I’ve tried the following script on the Event doctype:

frappe.ui.form.on('Event', {
    onload: function(frm) {
        if (frm.is_new() && frm.doc.reference_type === 'Opportunity') {
            frm.set_value('public', 1);
        }
    }
});

Is this the correct approach? Or is there a better hook I should use?

Thanks in advance!
