Project Description

Introduction provides the dynamic property infrastructure used by the client, project, milestone and ticket content objects of the horae.ticketing.


The package builds up on three main classes:

Container for persistent properties
A property providing one or more fields
An object based on the fields provided by the properties which are defined by the corresponding property containers

Objects using the property architecture have to subclass the mix in class and their add, edit and display forms have to subclass the corresponding base classes PropertiedAddForm, PropertiedEditForm and PropertiedDisplayForm defined in The properties for a propertied object are collected from all named adapters implementing and adapting the object. Sample implementations may be found in the horae.ticketing package.

There are five property containers implemented by which there are:

Global properties
Properties available for all propertied objects
Client properties
Properties available for clients
Project properties
Properties available for projects
Milestone properties
Properties available for milestones
Ticket properties
Properties available for tickets

Properties may be created or customized persistently using the GUI provided by Another way to define properties is by defining them as default properties which is done by registering a named global utility implementing Examples of such default properties may be found in the horae.ticketing package.

Property types

The package provides the following Property implementations defined in

A boolean property
A textline property
A text property
A rich text property
A choice property
A multiple choice property
A choice property having weighted options
A float property
A price property
A user property
A user role property
A group property
A group role property
A date time property

A Propertied object stores changes in a list of PropertyChange objects to preserve a changelog of the lifecycle. A view of the whole history may be provided by sub-classing the base class.
