Hi,
I'm doing a lot of this type of looping in my templates (from the docs:
https://docs.djangoproject.com/en/1.9/ref/templates/builtins/#for):
<ul>
{% for athlete in athlete_list %}
<li>{{ athlete.name }}</li>
{% endfor %}
</ul>
In this context, I find myself occasionally wanting to refer to data of the
previous athlete (if the instance exists) while working on the current athlete.
The way I do this right now is within a custom template tag. I copy the data of
interest into a session variable for use next time the custom template tag is
called. This works, but I'm wondering if there is a better way?
My thought was the following: what if there existed a .previous property
attached to the current instance that contains the previous instance for this
purpose?
IE:
<ul>
{% for athlete in athlete_list %}
<li>This time: {{ athlete.name }}, last time: {{ athlete.previous.name
}}</li>
{% endfor %}
</ul>
athlete.previous would obviously be None the first time round the loop.
