Thanks Mike,
I do not know if this will work.
I want to change the field in the template as I read each row.
I do this in PHP rather easy, but am confused on how to do this using
django.
I haven't done much php (only emergency repairs to stuff written by
others after they have disappeared!) so I don't know how easy that might be.
In Django templates you can use HTML and for-loops to do most things.
You just write a class in your view to get the data from a query_set and
construct a list of objects (in your case, each row and a list of all of
its individual choices as found - foreign key or many-to-many - in the
database) and render it in your template. There is plenty of template
power available ...
https://docs.djangoproject.com/en/1.4/ref/templates/builtins/
It might look like this ...
{% if list_of_row_objects %}
<ul>
{% for row_object in list_of_row_objects %}
<li>{{ row_object.field_name }}
<p>There are {{ row_object.choices|length }} choices
<ol>
{% for choice in row_object.choices %}
<li>{{ choice.name }}</li>
{% empty %}
<li>There are no choices for this row</li>
{% endfor %}
</ol>
</li>
{% endfor %}
</ul>
{% else %}
<p>Sorry, no list of row objects today!</p>
{% endif %}

I'm likely to want something similar soon so I googled "how do I
dynamically modify a django choice field" and got at least a page of
results. Here is one which I looked at and found interesting. It may
suit your needs ...

Good luck
