SahanaPy Workout @ FOSS.in/2009

SahanaPy is having a week-long workout at FOSS.in 2009

Description

SahanaPy is an example of HFOSS (Humanitarian FOSS). It is a RAD framework for developing Emergency Management applications. Sahana has been used to help support most major disasters since the Indian Ocean Tsunami including localised versions for floods in India (Bihar 2008 & Andhra Pradesh/Karnataka 2009). You can check Sahana's History here & here.

The core team will all be physically together in in one place for the week to really push our framework to the next level. We'll be extending a warm welcome to any Python/JavaScript programmers who wish to join in throughout the week. We will be polishing up our back-end REST/XSLT-driven XML/JSON controller & developing new front-end UI tools - flexible layouts with advanced widgets (based on ExtJS &/or jQuery dataTables/jEditable) & Growl-like notifications generated programmatically by the easy to use, lightweight & powerful Web2Py. We'll also be looking at improving our GIS functionality using Javascript toolkits like OpenLayers & GeoExt/MapFish. We'll also be fixing our Testing framework, based on Selenium.

How will people benefit from attending?

  • Get acquainted with a new python web framework Web2Py
  • Use advanced JavaScript functionality
  • Get a sense of fulfilment from contributing to HFOSS

What are we going to do?

Fran

  1. Ext
  • We're starting by hand-crafting Ext pages which interact properly with the back-end.
  • Later we are looking to generate these programmatically to restore RAD.
  • Trying different approaches:
    1. Add a new format=ext representation to the REST controller which uses ext versions of the default layouts which inherit from layout_ext.html
      • This seems very slow to load the different components (header, footer, content) into the Ext Viewport
      • Have optimised the model to reduce overheads here, but it still doesn't seem to be an optimal approach
    2. Ext forms embedded inside the standard layout
      • Making a start with the login form
      • Need to get the Web2Py form.custom to integrate with Ext
      • Can then add the Ext.ux.PasswordMeter to the register form :)
  • Other streams which can be worked on:
    1. Convert hyperlink buttons to Ext style
    2. Ext menus
    3. Ext popups
  1. GIS
  • Export Features as GeoJSON (using S3XRC with an XSLT)
  • Display Feature Details in Popups
  • Make Features Editable from the Map

Newcomers

Whilst any BluePrint is fine, suggestions for areas suitable for a newcomer:

  1. Volunteer Management Module
  2. Backups
  3. Appliance
  4. JS: Finish integrating the GPS coordinate converter into the GIS Location input form:
  • Convert JS to jQuery style
  • Get it working as a Popup
  1. CSS:
  • Provide a layout which allows tables to be scrolled when they exceed the width of the display
  • Provide an Ext theme
