I've added the summernote text editor to a textarea. And when I'm logged in as admin it works, but any other user gets just a normal textarea. In the console there is:

error: Some modules could not be started

Failed modules: ["tabla_project_ticket_web.web_editor"]

The js code:

odoo.define('tabla_project_ticket_web.web_editor', function (require) {
'use strict';

var website = require('website.website');


    $('textarea.load_editor').each(function () {
        var $textarea = $(this);
        if (!$textarea.val().match(/\S/)) {
            $textarea.val("<p><br/></p>");
        }
        var $form = $textarea.closest('form');
        var toolbar = [
                ['style', ['style']],
                ['font', ['bold', 'italic', 'underline', 'clear']],
                ['para', ['ul', 'ol', 'paragraph']],
                ['color', ['color']],
                ['history', ['undo', 'redo']],
                ['insert', ['link', 'picture']],
            ];

        $textarea.summernote({
                height: 300,
                toolbar: toolbar,
                styleWithSpan: false

            });

    });

});

Does any one know what could be the problem? In the odoo documentation Failed modules means that a javascript error is detected, but why does it run ok when logged in as admin? 

EDIT:

The summernote editor is shown only when the user has some website rights, editor or restricted editor. But I need to work this with only the Portal group rights. I've tried with the code from website_forum, but it doesn't work.
