The only piece of data that is passed back is the 'value' - this is
standard HTML and Django doesn't do any different. You will have to
map the values back to choices when checking the GET/POST data.
The clever thing to do, to obey DRY, is something like this:
view module:
------------
CHOICES = {
1: 'Choice 1',
2: 'Choice 2',
}
view code (for creating the form):
----------------------------------
context['choices'] = CHOICES.items()
# render_to_response stuff etc.
template code:
--------------
<select name="userchoice" size="1">
{% for choice in choices %}
<option value="{{ choice.0 }}">{{ choice.1|escape }}</option>
{% endfor %}
</select>
view code (for parsing input):
------------------------------
try:
choice = CHOICES[request.GET['userchoice']]
except AttributeError:
# handle invalid input
