Thanks, Roseman. I was hoping I wouldn't have to resort to custom
filters or tags, because it obfuscates template code that should be
really simple. Also, I don't think filters can be applied to this
slightly modified example:
{% for person in people %}
<tr>
{% for col in columns %}
<td{% if person.get(col) > too_large %} class="too-large"{% endif
%}>
{{ person.get(col) }}
</td>
{% endfor %}
{% endfor %}
I know Django templates were intentionally designed to disallow
passing arguments to methods; therefore, I'm assuming there must be a
clean way of implementing this example that I'm just not aware of.
