py4web gives error importing pydal due to FancyUrlOpener using python 3.14

[Davidiam]

One of our developers got an error starting py4web when it hit the import pydal statement in core.py :

Cannot import name 'FancyUrlOpener' from urllib.request

I found this article:

FancyURLopener and URLopener have been removed from Python 3.14 · Issue #58740 · nodejs/node

It seems that FancyUrlOpener no longer exists in python 3.14 and therefore py4web gives an error if you are using python 3.14 or higher in your environment.

Thanks for brining this up. 

FancyUrlOpener was in fact recently removed from py4web and pydal. Make sure you upgraded to the latest.
