It's considered 'poor form' by django devs - too much work in the
template. If you want the data in that order, arrange it so in the
view.
If you don't agree, add this 5 line template tag:
from django import template
register = template.Library()
@register.filter
def dict_get(hash, key):
return hash[key]
It should go in <some_app>/templatetags/dict_get.py
You can then do:
{% load dict_get %}
{% for dict in list_of_dicts %}
<tr>
{% for title in titles %}
<td>{{ dict|dict_get:title }}</td>
{% endfor %}
</tr>
{% endfor %}
Cheers
