Iterating Dictionaries in Django Templates
January 17, 2010
You can access both the key and value parts of a python dictionary directly from django templates.
Create Dictionary
This code builds up a dictionary of contest names to number of events.
for row in rows: lContestName = row[2] try: lCountAlready = lResults[lContestName] lCountAlready += 1 except KeyError: lCountAlready = 1 lResults[lContestName] = lCountAlready
Django Template
The django template then displays this in a table.
{% for contestname, eventcount in Venue.contests.items %} <tr> <td class="contest"><a href="/contests/{{contest.slug}}/">{{contestname}}</a></td> <td>{{eventcount}}</td> </tr> {% endfor %}
