data_domain requests with GET parameters always result in a 500 error

[kourylape]

An example of what I mean can be viewed here

The indicators variable is commented out, but still being used in the if else statement of data_domain and none of the GET parameters are actually being used.

Is it necessary to continue to use the if/else statement? Could something like this work instead?

def data_domain(request, geo_level_slug, geo_record_slug, data_domain_slug):
    """ Overview of a data domain for a geo record """
    level = get_object_or_404(GeoLevel, slug=geo_level_slug)

    try:
        record = GeoRecord.objects.defer('mappings', 'components', 'parent').get(level=level, slug=geo_record_slug)
    except GeoRecord.DoesNotExist:
        raise Http404

    filter_key = ''
    if level.related_within:
        geoids = json.loads(record.geo_id_segments)
        sum_lev = level.related_within.summary_level
        filter_key = geoids[sum_lev]

    domain = get_object_or_404(DataDomain, slug=data_domain_slug)
    levels = get_levels_as_list()

    return render_to_response('profiles/data_domain.html',
        {
            'geo_level': level,
