Is it possible to access the key_name of an object from inside a jinja2 template?

I'm using python google app engine with the webapp framework, substituting jinja2 templates for django templates.

I know you can get the key_name of an object from inside a handler method by calling it like so:

goody = object.key().name()

But is it possible to access the key_name from within the template logic? Something like this?

{% for object in objectList %}
{{object|key_name}}
{% endfor %}

Obviously that doesn't work, but is there some filter or hidden attribute I can use to get at the app engine key_name an object is stored with from inside the template without extra fiddling inside the handler method?

You can do object.key.name inside django template to access appengine datastore object's key name

Normally, you access key name in python code through object.key().name()

Django template automatically tries a few possible ways to interpret object.key.name to give you the value.

Jinja2 allows you to execute callables, just by using () according to the documentation here: http://jinja.pocoo.org/docs/templates/#other-operators

So, this should work:

{% for instance in instance_list %}
   {{ instance.key().name() }}
{% endfor %}
