Webware Scripts

Organization & Script Location

Each of the three web servers - WebProd, WebModel, and WebDevelop - has dedicated programs for running each individual web system. These programs are contained in the Context/ directory for each web server, /WebApp/webserver/Context/. Development is done in /WebApp/WebDevelop/Context/; model testing is done in /WebApp/WebModel/Context/; and production is in /WebApp/WebProd/Context/. Only WebDevelop is accessible by all programmers.

Each web system - eg, Agency, WebBill, etc - is contained in a sub-directory of Context/. The name of the sub-directory identifies which web system's files it contains; for example, /WebApp/webserver/Context/Agency/ contains all the files specifically for running the Agent Support pages. These directories also contain the .pyc file(s) which are created when a Python program is executed.

The Context/ directory itself contains files related to ALL web systems. Changes made to files there affect every web system. Because of this, files in the Context/ directory may not be modified by regular programmers. ANY changes to those files must be approved in advance and installed by the web system manager.

The Context/ Directory

This directory contains a number of files, some currently in use, others not. The two files of overriding importance to the web systems are TLPageV2.py and BuildV2.py.

TLPageV2.py

TLPageV2.py is the customized Page object used by our web systems. It is the super-class for all web pages and should only contain classes and functions needed by more than one of our web systems. Its ancestor is the Webware Page object.
