Access a list within a dict in request.POST - django

Question

In my html I am dynamically generating drop-down options with the same name
<form action="{% url manageCsv %}" method="post">
{% csrf_token %}
<p>
<input type="hidden" name="doc_id" value="{{ doc_id }}">
{% for column in file_columns %}
Column {{ forloop.counter0|add:1 }}
<select name="columns">
<option value="blank"></option>
{% for column_value in file_columns %}
<option value="{{ column_value }}">{{ column_value }}</option>
{% endfor %}
</select>
{% endfor %}
</p>
<p>
<input type="submit" value="Submit" />
</p>
</form>
UPDATE:
My Views.py :
def manageCsv(request):
if request.method == 'POST':
file_id = request.POST['doc_id']
csvColumns = request.POST['columns']
print >> sys.stderr, csvColumns['columns']
return HttpResponseRedirect(reverse('index'))
In my view when I print my request.POST I get everythin I need :
<QueryDict: {u'csrfmiddlewaretoken': [u'lGlxVmiYI9xFb5bV7cJPrP9GR0t0LYTi'], u'doc_id': [u'14'], u'columns': [u'Organisation', u'Sum of products']}>
But the problem I am facing is that when I assign csvColumns = request.POST['columns'] , csvColumns prints out only Sum of products from the list and not the entire List [u'Organisation', u'Sum of products']
How can I get the entire list ? What have I missed ?
Any help on this would be great
Thanks in advance

Try to do it like this as explained in the docs:
csvColumns = request.POST.getlist('columns',None)
Hope this helps!
