I have some code where I try to get a named template and render it and if it fails I render a default template instead. But this fails, presumably because the __call__ method of NamedTemplate does not return anything. From zope/formlib/namedtemplate.py (Zope 2.10):
class NamedTemplate(object):
def __init__(self, name): self.__name__ = name
def __get__(self, instance, type=None): if instance is None: return self return component.getAdapter(instance, INamedTemplate, self.__name__)
def __call__(self, instance, *args, **kw): self.__get__(instance)(*args, **kw)
I seems strange to me that __call__ does not actually return anything. Is it just me?
It returns only if you use "return" (otherwise, it returns "None"). Thus, try "return self.__get__(....)". -- Dieter
