I've posted a patch at the trac which would allow you to access the
template string.
This would work:
class MyTable(W.TableForm):
def __init__(self, name=None, **kw):
super(MyTable, self).__init__(name, **kw)
template = self.template
# modify template as you feel ...
self.template = template
I know it's not exactly the use case you described (modify the template
at class declaration), but I just noticed that when I was writing this
message :/
It's at:
http://trac.turbogears.org/turbogears/attachment/ticket/536/template_as_a_string.patch
It passes all unittests but some more (real-world and unit) testing
should be needed. Give it a try see if it helps
Regards, Alberto
