User Interface requirements

Blueprint for the Messaging Module

Current design is here:

User Guide:

What we need is:

User Interface

The 'Send Message/Alert' screen should have a small box to enter the Plain-text message which is sent to all recipients (using all available SMS/Email addresses in the Group specified).

There should be a 2nd box to create a Rich-text message, with the option of adding attachments. This content just gets sent to those members of the group with an Email address specified.

We don't need the option of having Email or SMS groups - all groups are 'Both'.

If a user is added to a group we warn about any missing details, but still allow addition (the ref is by so addresses can eb added/changed later anyway).

When sending we need to provide warning messages about users for whom details weren't available.

Email has mail settings:

# These settings should be made configurable as part of the Messaging Module

& a function:

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

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

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:

Rich Text

We'd like to be able to send HTML mails for rich-text support (including attachments) This requires the use of smtplib to send MIME-encoded files:


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).

Implementation details are here:

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

Toolkits we can base on:

Hardware compatibility databases:


Adding support for sending out/receiving alerts via Twitter would be nice. This is easy to do within base Web2Py, so this just needs a little UI work to integrate.
