SchoolBell
==========
SchoolBell is a free and open source application to allow groups and
organizations to coordinate schedules and timetables. Users may manage their
personal calendars, group calendars and calendars for resources, e.g., rooms,
projectors, etc, via a web interface, or using an iCalendar compliant client
such as Mozilla calendar or iCal.
SchoolBell is written in Python, and is a Zope 3 component as well as a
standalone calendaring server. It is part of the SchoolTool project, funded
by the Shuttleworth Foundation.

System requirements
-------------------
- Python 2.3 (http://www.python.org/)
(Debian users will need both python2.3 and python2.3-xml packages)
- Zope X3 (http://www.zope.org/)
(Users will require Zope X3 development trunk revision,
Zope libraries of this revision are included with the distribution)
- libxml2 Python bindings (http://xmlsoft.org/). Windows users can download libxml2 binaries here: http://users.skynet.be/sbi/libxml-python/
- Development environment and a C compiler
(pre-compiled binaries are available for Windows users at the SchoolBell website)
Building SchoolBell
-------------------
Run 'make build update-translations' to build the necessary extension modules
and translations.
It is a good idea to run 'make test' and 'make ftest' to check if all the
essential unit and functional tests pass.
Installing and Configuring with Distutils (optional)
----------------------------------------------------
It is possible to install SchoolBell using python distutils. To do this, you
have to use one of the distributed tarballs/zipfiles, which you unpack in a
directory with the tools appropriate to your OS. First, it is necessary to
install the version of Zope included with the tarballs, this can be done by
running
python setup.py install
from the Zope3/ directory included with the SchoolBell distribution. From the
top level directory of an unpacked SchoolBell tarball/zipfile SchoolBell can be
installed with:
python setup.py install
Finally, to setup a SchoolBell instance, copy the installed script into a
separate directory and create a config file with the name of the script and an
extension .conf. A good template can be found in the top level of the tarball
(.conf.in). Running this script will then run an instance in that directory.
Those interested in installing into a non-standard location should investigate
the --paths and --default-config option for the install distutils commands.
NOTE: If you are using a Linux distribution for which packages exist, you
should consider using those packages instead of this procedure.
Running SchoolBell
------------------
The top-level project directory contains the following executable Python
scripts:
schoolbell-server.py starts the SchoolBell server
The SchoolBell server automatically creates an empty database if it cannot find
an existing one. You can customize the location of the database and a few
other parameters in a configuration file called schoolbell.conf. There's
an example file called schoolbell.conf.in, you can simply rename it and modify
to suit your needs.
By default a user with manager privileges is created in the new database.
The username is 'manager', and the password is 'schoolbell'.
The default web application port is 7080. Once the server is running, you can
connect to it with a web browser.
The Makefile also contains several shortcuts, which are kept mainly for
backwards-compatibility:
make run starts the SchoolBell server
make build build SchoolBell and the included Zope 3 libraries
make test run the unit test suite on SchoolBell
make ftest run the functional test suite on SchoolBell
These commands are superseded by executable Python scripts in the top-level
directory.

Testing
-------
There are two sets of automated tests: unit tests and functional tests.
Unit tests (sometimes also called programmer tests) test individual components
of the system. Functional tests (also called customer or acceptance tests)
test only externally visible behaviour of the whole system.
Tests themselves are scattered through the whole source tree. Subdirectories
named 'tests' contain unit tests, while subdirectories named 'ftests' contain
functional tests.
To run all unit tests, do
python2.3 test.py -pv
To run all functional tests, do
python2.3 test.py -fpv
The test runner has more options and features. To find out about them, do
python2.3 test.py -h
Functional tests are are not completely isolated. Some functional tests
create named database state snapshots, while other tests reuse those snapshots
of known database state. The test runner does not know which tests create
which snapshots, so if you want to run just one (or a couple) of functional
tests in isolation, it is likely that you will have first run the full suite
to create the necessary snapshots. Do not restart the test server, or all
saved snapshots will be gone.
Virtual hosting
---------------
SchoolBell provides support for virtual hosting with Apache's mod_rewrite and
libproxy. For example, let's say you have two SchoolBell instances running on
ports 7001 and 7002, and you want to make them available as school1.example.org
and school2.example.org, both on port 80. In order to do that, add the
following to your Apache configuration file:
NameVirtualHost *:80
ServerName school1.example.org
RewriteEngine On
RewriteRule ^/(.*) http://localhost:7001/++vh++http:school1.example.org:80/++/$1 [P]
ServerName school2.example.org
RewriteEngine On
RewriteRule ^/(.*) http://localhost:7002/++vh++http:school2.example.org:80/++/$1 [P]
Also, enable mod_proxy and mod_rewrite.
You can also get SSL support in the same way, as an alternative to the build-in
SSL support:
NameVirtualHost *:443
ServerName school1.example.org
SSLEnable # Apache 1.3
# SSLEngine On # Apache 2.0
RewriteEngine On
RewriteRule ^/(.*) http://localhost:7001/++vh++https:school1.example.org:443/++/$1 [P]
The web application interface also supports virtual hosting in this manner,
the only differing thing would be the local port number.
