firstof as

[mail....@gmail.com]

What I'm after is something like {% with firstof obj.thing
obj.get_something as thing %}

Is there any way to do this short of writing my own template tag and
figuring out which exists first? Seems like it would be a fairly
common need.

Assuming obj is iterable, you can do: {% with
obj.0.thingobj.get_something as thing %}

...is that what you mean?

Not exactly, no. In my particular case, it's more of a check to see if
it's available, and if not, do a bit more work to get something that
will fill the current need. Or, in other words, maybe I'm storing it
locally, or maybe I'm not.

Another example:

{% with firstof obj.votes obj.get_votes as votes %}
Which would then let me do something with votes: "There have been
{{ votes }} vote{{ votes|pluralize }}.

Ah, ok; I see what you want to do. I'm not aware of any way to do this,
other than as you mentioned a custom template tag.

Instead of adding a template tag, you could handle this in the class for
obj. Just have get_votes() cache its result and use the cached value
after the first time get_votes() is called. In the template, always call
get_votes().
