Meta course

2006-01-01T19:41:59Z

Neverhood:

'''Metacourses''' are courses which take their enrolments from courses i.e. for every course 'enrolled' on the metacourse, all students in the course are enrolled in the metacourse.

Each time a student enrols on (or unenrols from) a course, s/he is enrolled/unenrolled from the metacourse(s) (although it doesn't happen immediately - it may take an hour to show up).

Please note that metacourse enrolments do not preserve groups.

==Metacourse setup==
Teachers are able to choose whether a course is a metacourse via the "Is this a metacourse?" (yes/no) checkbox in the [[course/edit|course settings]]. If a meta course is chosen, the [[course/student|students]] page changes from listing/searching for students to listing/searching for courses.

==Metacourse usage==
Metacourses may be used in a variety of ways. For example, consider a course C with units C1, C2, C3 and C4.

*Scenario 1: C is a metacourse with C1, C2, C3 and C4 as normal courses. Students enrolling on C1 or C2 or C3 or C4 are automatically enrolled on C.

*Scenario 2: C1, C2, C3 and C4 are metacourses with C as a normal course. Students enrolling on C are automatically enrolled on C1, C2, C3 and C4.

In both diagrams the arrows denote the direction in which the enrolments are fed.

Backup and restore FAQ

2006-01-01T19:41:57Z

Neverhood:

;Site backups
:Site backups, as explained in [[Upgrading_Moodle#Backup_important_data|upgrading Moodle]], are recommended in order to have all data saved with the best confidence and the shorter recovery time.

;Course backups
:Course backups, configured on the [[admin/backup|backup]] page, are more expensive in terms of time and CPU usage. The recovery time to have your site running again is longer. Course backups are useful for obtaining "fresh" copies of courses to be re-used or distributed individually, however they should never be used as a primary backup system (unless your hosting doesn't allow the preferred site backups).

===How do I backup my whole Moodle site?===

There are two main things you need to make a copy of - the database and the uploaded files. The Moodle scripts themselves are less important, since you can always download a fresh copy if you have to.

There are many ways to do such backups. Here is an outline of a little script you can run on Unix to backup the database (it works well to have such a script run daily via a cron task):

cd /my/backup/directory
mv moodle-database.sql.gz moodle-database-old.sql.gz
mysqldump -h example.com -u myusername --password=mypassword -C -Q -e -a mydatabasename > moodle-database.sql
gzip moodle-database.sql

For the files, you can use rsync regularly to copy only the changed files to another host:

rsync -auvtz --delete -e ssh mysshusername@example.com:/my/server/directory /my/backup/directory/

===Error: An error occurred deleting old backup data===

This part of the backup (or restore) procedure tries to delete old info, used in previous executions, performing the following tasks:

* Delete old records from "backup_ids" table: Check the table exists, repair it and try again.

* Delete old records from "backup_files" table: Check the table exists, repair it and try again.

* Delete old files from "moodledata/temp/backup": Delete the dir completely and try again.

There are various ways of repairing tables, including using MySQL Admin.

===XML error: not well-formed (invalid token) at line YYYY===

This problem can appear at any point in the restore process. It's caused when the XML parser detects something incorrect in the backup file that prevent correct operation. Usually, it's caused by some "illegal" characters added in the original course due to some copy/paste of text containing them (control characters, or invalid sequences...).

The best method to handle this issue is:

* Unzip the problematic backup file under one empty folder.

* Open the moodle.xml with Firefox. It will show you where (exact char) the problem is happening.

* Edit the moodle.xml file with some UTF8-compatible editor and delete such characters. Save changes.

* Test the moodle.xml file again with Firefox until no error was displayed.

* Zip everything again (all the folder contents but the folder itself!).

* Restore the course. It should work now.

Also, if possible, it's highly recommended to solve those problems in the original course too from Moodle itself. Once "repaired" there, problems will be out if you create new backup files in the future.

=== Some of your courses weren't saved!! ===

There are two possible causes of this problem:

1. Error - this happens when the backup procedure has found an error and so hasn't finished the backup of a particular course. These are "controlled" errors and the scheduled backup continues with the next course.

2. Unfinished - this happens when the backup procedure dies without knowing why. When the cron is next executed it detects that the last execution went wrong, and continues skipping the problematic course. A possible solution would be to raise the PHP/Apache limit in your installation (memory, time of execution...). By taking a look to your log tables you should be able to see if the "crash" is happening at exact time intervals (usually a problem with the max_execution_time php's variable), or if there is some exact point were all the courses are breaking (generally internal zip libraries, try to switch to external executables instead).

MoodleDocs:Guidelines for contributors

2006-01-01T19:41:21Z

Neverhood:

You are welcome to contribute to MoodleDocs :-) Find something that can be improved, either in content, grammar or formatting, and fix it.

== Contributing to MoodleDocs ==

* Although it is possible to edit the documentation as an anonymous user, please [[Special:Userlogin|create an account or login]].
* Please note that all contributions are released here under [http://www.gnu.org/copyleft/fdl.html GNU Free Documentation License 1.2].

== Documentation for every page ==

* Moodle 1.6 will have a button in the header that links to pages in the wiki with the same path as the pages in Moodle. For example, the documentation page "Viewing and grading submissions" explains what can be seen on the page in Moodle where the teacher can view and grade assignment submissions. The URL of that page is something like <code>yourmoodlesite.org/mod/assignment/submissions.php</code>. When contributing to the documentation, if it contains part of a URL, say <code>mod/assignment/submissions</code>, it means that this documentation page refers to that page.
* Please note that the [http://moodle.org/help.php?file=index.html Moodle help files] will remain in each language pack and so their text need not be included in this documentation.

== Additional documentation ==

You are welcome to create pages for additional documentation. Simply type <code><nowiki>[[newpagename]]</nowiki></code> and follow the link to start editing the new page. Please choose a short name (just one or two words) and capitalize the first word only.

1.5 theme upgrade

2006-01-01T19:41:13Z

Neverhood:

{{Themes}}
From Moodle version 1.5 and higher CSS support is extended throughout Moodle to remove hardcoded styles e.g. fonts or colours, from the HTML code. As a result, Moodle themes are a lot more flexible and accessible, but this also means that custom themes written for Moodle version 1.4.x and earlier may no longer work well.

The best approach when upgrading is to reconstruct your theme again from scratch, borrowing graphics and styles from your old theme as necessary. This approach will result in a more robust theme that will survive future upgrades of Moodle.

The instructions below therefore apply whether you are upgrading or not.

== Upgrade or install Moodle 1.5 or higher ==

Install Moodle as normal. If you are upgrading, your old theme directory will remain, but the installation process will set the theme to the new default ''standardwhite''.

== Create a new theme directory ==

Themes are all stored in the ''theme'' directory of Moodle.

To create a new theme directory, make a copy of the ''standardwhite'' directory (or any other theme) and name it appropriately.

Inside this new directory you will see the following files.

:''config.php'' - edit this to change parameters for your theme
:''favicon.ico'' - the site icon that shows in the browser location bar or bookmarks
:''header.html'' - a fragment of HTML that defines the top of your pages
:''footer.html'' - a fragment of HTML that defines the bottom of your pages
:''gradients.css'' - an actual stylesheet containing styles to add to your theme
:''gradient.jpg'' - an image file, you can add as many as you want
:''styles.php'' - the actual script that Moodle calls, there is no need to change this

== Create a new CSS file ==

Your theme can have as many CSS files as you like. Create a new one, e.g. ''mystyles.css'', and include it in your theme by editing ''config.php'' and changing <code>$THEME->stylesheets</code>. You may remove ''gradients.css'' if you don't want it.

This new CSS file is where you will be adding styles that override ones from the standard stylesheet or set new ones.

While you're looking in ''config.php'', read through it to get an idea of the other things that you can do.

== Make your theme the active one ==

Choose your new theme from the list on Administration >> Configuration >> Themes. (Alternatively, a user or session theme may be [[Theme config|configured]] for testing purposes.)

== Changing the header and footer files ==

The header and footer files define the layout for the top and bottom of pages.

The first thing most people want to do is to add a logo to the front page. The easiest way to do this is to edit the header file. Look closely at the code in header.html and you'll see there is different code for different parts of Moodle. [[Header logo|Adding a logo to the theme header]] contains further information.

Warning: If upgrading from 1.4, don't just copy your old header and footer files over as they have changed substantially.

== Start adding new CSS styles ==

Start adding classes to your CSS file, one by one. The best way to find out what styles you want to change is by using one of the following tools:

* Andrew Walker's [http://www.moddular.org/log/css-inspector/ CSS Inspector] - this enables you to easily view details of an element, including its ancestors and any class and id attributes
* [http://chrispederick.com/work/firefox/webdeveloper/ Web Developer Extension for Firefox]

== Clear your browser cache==

Please remember that browsers usually cache CSS files, so a forced refresh (Ctrl+F5) is required in order to see any changes.
