Hear me out. :) My use case is this: I have a large table, I have already
ordered the objects that will make up each row according to a certain key
attribute. What I would like to do is use the 'cycle' tag together with
the 'ifchanged' tag to change the bg-color of the rows only when this key
attribute has changed. E.g.:
{{{
(blue) New Mexico John ...
(blue) New Mexico Jill ...
(blue) New Mexico Jeff ...
(green) Texas Jack ...
(green) Texas Jane ...
(blue) Arizona James ...
...
}}}
But, it just can't be done (in the template) as things stand. Every access
of the 'cycle' tag (whether named or not) gives the next value in the
cycle. I propose an alternate tag that picks up the cycle variable without
changing it from its last appearance. Then code like this ought to be able
to accomplish the task:
{{{
{% ifchanged state %}
<tr style="background:{% cycle 'blue' 'green' as rowbg %};">
{% else %}
<tr style="background:{% dontcycle rowbg %};">
{% endifchanged %}
}}}
I really believe this is a legitimate presentation task. Thanks for your
consideration. K.C.S.
