Well, the problem is not really with the template code - mostly
trivial FWIW, but mostly : how do you decide which attributes you want
to display for a given object ? Once you have this sorted, you can
preprocess the objects list in the view code as Steve suggested:
# views.py
def view(request, ...):
objects = however_you_get_your_objects()
attributes = however_you_get_the_attribute_names()
data = []
for obj in objects:
data.append(tuple(getattr(obj, attr) for attr in attributes))
context = {
attributes=attributes,
data=data
}
return render_to_response("template.html", context)
# template.html
<table>
<tr>
{% for name in attributes %}
<th>{{ name }}</th>
</tr>
{% endfor %}
{% for row in data %}
<tr>
{% for field in row %}
<td>{{ field }}</td>
{% endfor %}
</tr>
{% endfor %}
</table>
This of course imply that your objects list is homomgenous...
