How to debug product development

Abstract

Simple Python classes do amazing things once they inherit Zope machinery classes such as Acquisition, Persistent, Access control.

Testing your products without restarting the server is possible if you knew how.

Steps

These worked for me in Windows, ymmv.

1. CD "\Program files\website\lib\python"
2. "\Program files\website\bin\python.exe"
3. >>> import Zope, ZPublisher
4. >>> from Products import ZGDChart
5. >>> shortcut= ZGDChart.ZGDChart.ZGDChart

   Just a comment about the long incantation.

   ZGDChart is Products/__init__.py

   ZGDChart.ZGDChart is Products/ZGDChart.py

   ZGDChart.ZGDChart.ZGDChart is Products/ZGDChart.py/ZGDChart class

6. >>> c = shortcut(id=newid)
7. Test a method on the new instance:

   >>> c.version()

8. do some changes in ZGDChart.py
9. >>> reload (ZGDChart.ZGDChart)
10. repeat steps 5 - 6 until product works.
