[TurboGears] Re: TurboCheetah template access to widgets and a "Thank You" to Christopher Arndt

Thanks again Chris! I confirmed that the getVar() method works for me.
As for the getattr(), the following error is thrown:
Page handler: <bound method Root.index of <useplex.controllers.Root

It's nice to hear that somebody found this useful :-)

Normally ${aWidget.render()} should work, but the autocalling feature of
the Cheetah namemapper seems to get in the way here. I think this is a
bug and have brought it up on the Cheetah mailing list*, but did not get
a reply yet.

You can work around it using either of the two following syntax forms:

${getattr(aWidget, 'render')()}

or

${getVar('aWidget.render', autoCall=False)()}
