If you need a simple content refresh system, let me show you an example of a simple (yet powerful) implementation.

Step 1
Download a the lightweight ajax library from ImpliedByDesign, and copy it to a directory called “ajax” in your module directory.

Step 2
Add the following two functions to your drupal module

function printAjaxJs() {
   drupal_add_js(drupal_get_path('module', 'myModule').'/ajax/ajax.js');
}
function printAjaxFunction($function,$page) {
  $output.='function '.$function.'(div_id,content_id) {';
  $output.='subject_id = div_id;';
  $output.='content = document.getElementById(content_id).value;';
  $output.='http.open("GET", "'.$page.'" + content, true);';
  $output.='http.onreadystatechange = handleHttpResponse;';
  $output.='http.send(null);';  $output.='}';
  drupal_add_js($output,'inline');
}

Step 3
Ajaxfy your forms/pages

  printAjaxJs();
  $function="showContent";
  printAjaxFunction($function,"/show/content/");
  $script=$function."('updated-field','edit-myselect')";
  $form['myForm']['mySelect'] = array(
  '#type' => 'select',
  '#title' => t('Formation Select'),
  '#default_value' => $fdefault,
  '#options' => $foptions,
  '#prefix' => '
',
  '#suffix' => '
The output of /show/content/*value* will be updated here.

',
);

Below you can find a ‘howto’ on setting up an automated update system for your ubuntu system. In essence we’ll be setting up the whole aptitude mechanism thru cron.

WARNING : This may cause unexpected results due to unknown updates.

Open up the crontab as root

kvaes@ubuntu:~$ sudo crontab -e

Add the following line to your crontab

0 0 * * * aptitude -y update && aptitude -y upgrade && aptitude -y dist-upgrade && aptitude -y autoclean

Sidenote: If you prefer the gui, check the following article. It won’t do exactly the same, but it might give you a better feeling…

For some odd reason, after testing out some modules I was given an access denied on all content for non-admin users. If you would get such a thing, and are at the end of the road with your options, try the following commands:

INSERT INTO users (uid, name, mail) VALUES (‘0′, ”, ”);
INSERT INTO users_roles (uid, rid) VALUES (0, 1);
INSERT INTO node_access VALUES (0, 0, ‘all’, 1, 0, 0);

It will either return ‘duplicate entry’ warning (ignore this) or -maybe- fix your problem…

There are two simple ways:

Fast, but less verbose

kvaes@ubuntu:~$ cat /etc/issue
Ubuntu 7.04 \n \l

Verbose, but a tad slower

kvaes@ubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 7.04
Release: 7.04

I hope this helps…

This version contains a bugfix and the new “PostOnly”-feature. By selecting this feature, you won’t be pestered by non-posts in your listing. Examples here are the “Flavicon” & the “Homepage”.

Have fun with the release. Suggestions are always welcome!
