The data is stored in an SQL dump file, in ``examples/db/sample.sql``.
37
You must import this data into a **fresh** IVLE database. If you already have
38
a working IVLE install, it will have to be erased. A script is provided
39
which performs the following tasks:
41
* Unmounts all users with accounts in the current database,
42
* Drops the IVLE database if it already exists (prompting first),
43
* Creates and initialises a new IVLE database, as per :ref:`database-setup`,
44
* Populates the database with the sample data,
45
* Creates data directories and subversion repositories for all users, backing
46
up directories for any existing users.
48
The script is executed with the following command from the IVLE source
51
sudo ivle-loadsampledata examples/db/sample.sql
53
.. warning:: This script essentially destroys all contents in an existing IVLE
54
installation. Be sure you wish to do this.
56
.. note:: The script may fail at the "dropping database" phase if Apache or
57
another process are using the database. It is best to *restart* (not stop)
58
Apache before executing the script (``sudo /etc/init.d/apache2 restart``).
60
If the database exists, but is not properly initialised, then the script
61
may fail. In this case, you should manually run ``ivle-mountallusers -u``,
62
then drop the database, to ensure a clean build.
64
If there are any existing users (including sample users from previous runs
65
of the script), their files and subversion repos will be moved out of the
66
way to a backup location, ``/var/lib/ivle/jails-removed-<date>/``.
67
If you run this script regularly, your ``/var/lib/ivle/`` will become full
68
of these backups, so you may wish to remove them often. However, they are
69
typically fairly small (a few hundred kilobytes each), because they only
70
contain user content, not the full jail image.
35
You must import this data into a **fresh** IVLE database. You can
36
re-initialise your database by running ``sudo -u postgres dropdb ivle``, and
37
then following the database setup instructions, in the section
38
:ref:`database-setup`.
40
The data may be imported by running the following command::
42
sudo -u postgres psql ivle < examples/db/sample.sql

The repository for user "studenta" has a few sample files. All of the
137
directories must be checked out (using the Checkout button) before the files
138
can be seen from the IVLE application.
140
* :file:`stuff/Welcome to IVLE.html`: A simple web page, which can be
141
displayed with the "Serve" command.
142
* :file:`stuff/hello.py`: A simple Python script, which can be executed with
143
the "Serve" command. This file has a few edits in its revision history.
144
* :file:`ivle-102/mywork/phase1.html`: A file for a student's project
146
* :file:`group1/phase2.html`: A file for a group project submission. This
147
contains edits by both studenta and studentb, and is also accessible if
148
logged in as studentb.

The subject ivle-102 (2009 semester 2) has two project sets and three
154
projects. This demonstrates the relationship between project sets and
157
The first project set is a solo project set (every student works by
158
themselves on all projects). It has one project in it.
160
The second project set is a group project set, for groups of 3. That means
161
students work in the *same* group of 3 for every project in the set. It has
162
two projects in it, demonstrating that the students get to keep their group
163
(including all of the group files) across the two projects in this set.
165
Projects 1 and 2 have their due date set in the year 3009, so they will always
166
be submittable. Project 3 was due in 2009, so it has already closed.
168
Finally, there is a single group for projects 2 and 3, which has the students
169
studenta and studentb enlisted.
174
There is currently a single exercise, ``factorial``, which prompts the user to
175
write a factorial function and tests its correctness.
180
There is currently a single worksheet in the subject ivle-102 (2009 semester
181
2). It embeds the exercise ``factorial``.
