Report Generation Module

PollyReports.py provides a set of classes for database report writing. It assumes that you are using Reportlab to do PDF generation, but can work with any “canvas-like” object as desired.

PollyReports provides a framework for report generation. The developer instantiates a Report object, passing it a data source and passing or assigning one or more Band objects. A Band, in turn, will contain a list of Elements representing data items, labels, or system variables which will be printed. When the Report object is fully populated, its generate() method is called, passing in a Reportlab Canvas object (or any object providing a similar interface); the Report object then consumes the data source and renders the various Bands of Elements into the Canvas object.

The data source must be an iterator that produces objects that can be accessed via [] operations, meaning mainly dict, list, and tuple types, i.e. the most common types of records returned by standard database modules.

This version is written for Python 2.7, but should be easily adapted to Python 3.
