Blueprint for the Messaging Module

Current design is here:

• ​http://wiki.sahana.lk/doku.php?id=dev:msg_archi

User Guide:

• ​http://wiki.sahana.lk/doku.php?id=doc:message:english

What we need is:

• Contacts List
• Admin UI for:
  • Email Settings
  • SMS Settings
• CAP alerts: ​http://talksahana.com/2009/03/04/firefox-browser-cap-alerting-plugin-sahana-idea-for-gsoc2009/
• SMS alerts
• SMS login / data entry / reports
• J2ME client

Email

tools.py has mail settings:

mail=MailS3()
# These settings should be made configurable as part of the Messaging Module
mail.settings.server='mail:25'
mail.sender='sahana@sahanapy.org'

& a function:

mail.send(to, subject='None', message='None')

Can use this to send emails with dynamic data inserted into templates (like HTML pages):

• ​http://groups.google.com/group/web2py/browse_thread/thread/f6c903f9c67cfe2e

smtplib is required for sending HTML mails (MIME encoded):

• ​http://groups.google.com/group/web2py/browse_thread/thread/3d8ed693dd2f29bc
• Simple app for sending mails from a form (using smtplib): ​http://mdp.cti.depaul.edu/appliances/default/show/10

There is a Cron job to check the contents of the OutBox & send pending messages. On Success it moves the message to the 'Sent' table:

• ​http://web2py.com/examples/default/cron

SMS

The SMS Daemon to handle Inbound messages is a separate Python script.

It can distinguish between simple messages (added to the InBox of the Messaging Module) & those which are encoded in Binary XML (the output of XForms from the J2ME client).

Q: Do we use Cron to check OutBox & signal the daemon to send Pending messages? (as for email)

Toolkits we can base on:

• RapidSMS (Python-based): ​http://rapidsms.org
• PySerial: ​http://pyserial.wiki.sourceforge.net/pySerial
• Gammu: ​http://www.gammu.org (Python-gammu: ​http://www.gammu.org/wiki/index.php?title=Gammu:Python-gammu)
• Gnokii: ​http://www.gnokii.org (PyGnokii: ​http://mobilehacking.org/index.php/PyGnokii)
• Kannel: ​http://kannel.org (PyKannel: ​http://mobilehacking.org/index.php/PyKannel)
• SMSTools: ​http://smstools3.kekekasvi.com
