SchoolTool
==========

SchoolTool: the Global Student Information System

| Website: http://www.schooltool.org/
| Documentation: http://book.schooltool.org/
| Mailing list: https://launchpad.net/~schooltoolers
| Bug tracker: http://bugs.launchpad.net/schooltool


Overview
--------

SchoolTool is an open source, web based student information system designed for
schools in the developing world, with strong support for translation,
localization and automated deployment and updates on Ubuntu.


System requirements
-------------------

- Python (http://www.python.org/)

- libicu-dev: International Components for Unicode libraries (http://icu.sourceforge.net/download/)

- the Python Imaging Library (PIL) (http://www.pythonware.com/products/pil/)

- (optional) the ReportLab Toolkit (http://www.reportlab.org), and
  Liberation TrueType fonts.  ReportLab is only needed if you want to
  generate PDF reports and calendars.  To enable PDF support you will
  need to specify the path to fonts in the configuration file.

On Ubuntu (or Debian), you can install the needed tools and libraries by::

  $ make ubuntu-environment

If that suceeded, you can skip to `Building SchoolTool from Source`_.

What is being installed, is detailed below.

Basic C development tools::

  $ sudo apt-get install build-essential

Python development libraries and virtualenv::

  $ sudo apt-get install python-dev python-virtualenv

Unicode library::

  $ sudo apt-get install libicu-dev

Python Imaging Library, to build it you need freetype and jpeg development libraries::

  $ sudo apt-get install libfreetype6-dev libjpeg62-dev

gettext, needed to compile translations::

  $ sudo apt-get install gettext

For PDF generation to work need fonts::

  $ sudo apt-get install ttf-liberation

Other tools::

  $ sudo apt-get install libxslt1-dev enscript


Building SchoolTool from source
-------------------------------

Run ``make`` to download and install all the required zope packages into
the eggs folder::

  $ make

It is a good idea to run tests to check the installation::

  $ make test ftest

If you are running from a bzr checkout, you need to compile translation
catalogs::

  $ make compile-translations


Creating a SchoolTool Instance
------------------------------

An "instance" is a set of configuration files and data directories, that contain
everything needed to run a server for one school.

Let's create one::

  $ make instance

An instance of SchoolTool is created in the ``instance`` directory.

Database is ZODB_, in a single file ``instance/Data.fs``.

Location of the database, logs, and a few other options can be changed in a
configuration file ``instance/schooltool.conf``.

One of the options is developer mode, that allows you to add sample data,
introspect the database, and other useful things. Uncomment a
line that says ``devmode on``. You don't want to leave this on for a production
server, however.

.. _ZODB: http://zodb.org


Running SchoolTool
------------------

To start::

  $ make run

Once the server is running, go to http://127.0.0.1:7080 in the browser.

Server is started on local port 7080. You can change the port in the file
``instance/paste.ini``.

You will most likely want to make SchoolTool available on port 80. But this port
is reserved for the web the server. You will have to configure a virtual host or
a path in web server configuration. See `Virtual Hosting`_.


Securing SchoolTool
-------------------

Beware that the file which contains the database, `Data.fs`, is not given any
special permissions to prevent it from being read by other users by default.
You will have to change the umask or the permissions of the file manually to
prevent unauthorized access.

By default a user with administrator privileges is created in the new database.

| Username: manager
| Password: schooltool

You SHOULD change the password after your first login by clicking on `SchoolTool
Administrator` in the top right and then `Change password` in the left sidebar.

    schooltool/         Python package 'schooltool'


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::

  $ bin/test -u

To run all functional tests::

  $ bin/test -f

The test runner has more options and features.  To find out about them::

  $ bin/test -h


Unit test coverage
------------------

All code should be covered by unit tests.  The test runner can help you look
for untested code by producing code coverage reports.

To generate unit test coverage reports, run::

  $ make coverage

This command will run the full SchoolTool unit test suite and produce a
number of files (one for each Python module) in `./coverage/`.  Every
report file contains the source of the corresponding Python module.
Each source line is annotated with a number that shows how many times
this line was reached during testing.  Watch out for lines marked with
``>>>>>>`` as they indicate code that is not unit tested.

A prettier HTML version of the coverage reports can be generated with::

  $ make coverage-reports-html

Look at HTML files in `./coverage/reports/`.  You should have enscript installed
for syntax highlighting source files.

The HTML version of coverage reports is published nightly at
http://source.schooltool.org/coverage/


Translation
-----------

Translation template is `src/schooltool/locales/schooltool.pot`, there are
translatable strings extracted from source. Translation templates are used
to update translations and create new ones. To regenerate the template::

  $ make extract-translations

Translation files live in `src/schooltool/locales`.  There is a
directory for each language that contains a subdirectory
`LC_MESSAGES` that contains the compiled `.mo` files.
The `.mo` files must be present if schooltool is to use them and are
built by the command::

  $ make compile-translations

To start a new translation, use `src/schooltool/locales/schooltool.pot` as a
template (copy it to YOUR_LANG.po).  Generate `.mo` files with ``msgfmt`` (or
``make compile-translations``).


Virtual hosting
---------------

SchoolTool provides support for virtual hosting with Apache's mod_proxy_. The
standard instance is running on port 7080.  You want to make it available on
``school1.example.org`` port 80.  Add the following to your Apache configuration,
best place it in a separate file ``/etc/apache/sites-available/school1.example.org``::

  <VirtualHost *:80>
    ServerName school1.example.org

    <Proxy *>
        order allow,deny
        allow from all
        deny from none
    </Proxy>

    ProxyPass / http://127.0.0.1:7080/++vh++http:school1.example.org:80/++/

  </VirtualHost>

You need to enable Apache modules ``mod_proxy`` and ``mod_proxy_http``::

  $ sudo a2enmod proxy_http

Then enable the site and restart apache::

  $ sudo a2ensite school1.example.org
  $ sudo service apache reload

If you cannot, or don't want to, setup a subdomain for schooltool, you can make
it available at a custom path on another site, e.g. ``example.org/schooltool``.
Place the path before the last ``++`` in the URL, and put it somewhere in
the configuration of that site::

    ProxyPass /schooltool http://127.0.0.1:7080/++vh++http:example.org:80/schooltool/++/

For more information, see `Setting Up Virtual Hosting`_ in Zope documentation.

.. _mod_proxy: http://httpd.apache.org/docs/current/mod/mod_proxy.html
.. _Setting Up Virtual Hosting: http://wiki.zope.org/zope3/virtualhosting.html


HTTPS
-----

It is recommmended to use HTTPS/SSL to best protect your users. The
configuration is similar, just use port 443 and https instead of http::

  <VirtualHost *:443>
    ServerName school1.example.org

    SSLEngine On
    SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
    SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.pem

    <Proxy *>
            order allow,deny
            allow from all
            deny from none
    </Proxy>

    ProxyPass / http://localhost:7080/++vh++https:school1.example.org:443/++/

  </VirtualHost>

For SSL to work, you need a SSL certificate. Read Ubuntu documentation on
OpenSSL_ about creating one.

.. _OpenSSL: https://help.ubuntu.com/community/OpenSSL#SSL_Certificates

The ``mod_ssl`` module has to be enabled::

  $ sudo a2enmod ssl

When you get this working, you may want to redirect users that connect through
regular HTTP to the secure site.  Remove the ``ProxyPass`` for port 80 and
replace it with a ``Redirect``::

  <VirtualHost *:80>
    ServerName school1.example.org
    Redirect / https://school1.example.org/
  </VirtualHost>
