Question

I am using Muk Documents plugin inside Odoo ERP. However I want to make my pdf documents non-printable & non-downloadable. The code snippet:

updateActions: function () {
this.$actions.empty();
if (this.activePreview) {
if (this.activePreview.downloadable) {
this.$actions.append($("<a>", {
'class': "mk_preview_download",
'html': '<i class="fa fa-download" />',
'title': _t("Download"),
'href': this.activeFile.url,
                }));
            }
            if (this.activePreview.printable) {
                this.$actions.append($("<a>", {
                    'class': "mk_preview_print",
                    'html': '<i class="fa fa-print" />',
                    'title': _t("Print"),
                    'href': '#',
                }));
            }
            _.each(this.activePreview.contentActions(), function(action) {
                this.$actions.append(action);
            }, this);
