New description:
If you try to access an object property in a django template, and this
property raises a TypeError, then nothing will be raised. If it raises,
let's say, a ZeroDivisionError, then the exception is raised.
{{{#!python
from django.template import Context, Template
class FooClassTypeError:
@property
def fooproperty(self):
raise TypeError
return "somevalue"
class FooClass:
@property
def fooproperty(self):
return 1/0
t = Template("{{ obj.fooproperty }}")
# This call does not raise anything
t.render(Context(dict(obj=FooClassTypeError())))
# This call raises an exception
t.render(Context(dict(obj=FooClass())))
}}}
I think the expected behavior is that both exceptions should be raised.
What do you think?
