ExtJS based UI for Eden

S3XRC being a powerful backend that serves XML and JSON in a RESTful manner has now got a front-end framework that can exploit its positives. S3UI - the new ExtJS based front-end help us not only utilize S3XRC but also save a lot of bandwidth by exchanging information in JSON instead of full page reloads. This in turn aims to create an easy and quick workflow for different tasks that a user does with Sahana Eden.

Architecture

S3UI Framework is has 4 major components

• Custom views - these views contain appropriate javascript and html required to render the S3UI widgets, however they are minimal and look almost similar to old views for matter of simplicity and similarity.
• Javascript -
  • _s3ui_list.js - generates the grid view, included by _s3ui_list and _s3ui_list_create views -
    • Setting up metadata
    • fetching column model
    • Parsing json data from s3xrc into an Ext Datastore
    • Configuring and rendering a Grid widget on desired DOM element
  • core.js -
    • Provides S3UI objects and S3UI_Elements list
    • Manages creation of different widgets - used in custom views
    • Naming convention -
      • data_FunctionName - any function pertaining to parsing, formatting or manipulating data, nothing that affects UI
      • tools_FunctionName - various helpers that aid larger widgets - Eg. plugin implementors, micro-widget generators (date picker, checkbox, combo box)
      • widget_FunctionName - Larger widgets that can be used directly to create new visible UI elements
  • plugins - various ExtJS based plugins used by core.js
