getattr not working on Namespace

[sqlalchemy-bot]

Migrated issue, originally created by Anonymous

The method runtime.py:Namespace:__getattr__ raises RuntimeException when I think it should raise AttributeError.

This comes up when you try to do this in your template:

my_attr = getattr(my_namespace, my_attrname, None)

and there is no match for my_attrname. The expected behavior would be for None to be returned but instead RuntimeException does not get caught by getattr.

The use of AttributeError is mentioned here:
http://docs.python.org/reference/datamodel.html#object.__getattr__
