Provides the dynamic property infrastructure used by the Horae resource planning system
Project description
Introduction
horae.properties provides the dynamic property infrastructure used by the client, project, milestone and ticket content objects of the horae.ticketing.
Usage
The package builds up on three main classes:
- Properties
Container for persistent properties
- Property
A property providing one or more fields
- Propertied
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 horae.properties.propertied.PropertiedMixin mix in class and their add, edit and display forms have to subclass the corresponding base classes PropertiedAddForm, PropertiedEditForm and PropertiedDisplayForm defined in horae.properties.views. The properties for a propertied object are collected from all named adapters implementing horae.properties.interfaces.IProperties and adapting the object. Sample implementations may be found in the horae.ticketing package.
There are five property containers implemented by horae.properties 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 horae.properties. Another way to define properties is by defining them as default properties which is done by registering a named global utility implementing horae.properties.interfaces.IDefaultProperty. Examples of such default properties may be found in the horae.ticketing package.
