How to make attachment 'read-only' on Service Portal ("g_form.disableAttachments" not working)?

Aki18 · ‎11-16-2022

I created the following Client Script to make attachment 'read-only' when "u_state" is NOT "2".

function onLoad() {
	var state = g_form.getValue('u_state');
	if (state != '2')  {
		g_form.disableAttachments();
	}
}

It works properly for Classic (Platform) UI, but NOT for Service Portal...

Is this method NOT compatible with SP? If so, is there any alternative way to make attachment 'read-only' based on the condition above?

Best Regards,

Aki

@Aki18 TRY THIS

if (current.table_name == "custom_table_name") {
    var gr = new GlideRecord('custom_table_name');
    gr.addQuery('sys_id', current.table_sys_id);
    gr.addEncodedQuery('u_state!=2');
    gr.query();
    if (gr.next()) {
        answer = false;
    } else {
        answer = true;
    }
}

Also try to put some logs in if loop to check if its going inside for loop

Thanks

@Aki18

why not use ACL on sys_attachment?

disableAttachments() hides the attachment and doesn't make it readonly

Hi @Ankur Bawiskar ,

Thank you for your reply, but setting write ACL on sys_attachment affects al the tables, correct?

I would like to make attachment read-only in a specific table only. What kind of ACL script meets this requirement?

@Aki18

in the ACL of sys_attachment you can give condition for table name so that ACL will only evaluate for your table
