How to add custom range of date in django?

Using Django
1

I want to add custom range of date like, in my start date I don’t want to select future date it should be less than or equal to today.

    class PartLogFilter(django_filters.FilterSet):
        transaction_time = django_filters.DateRangeFilter(
            label='Transaction Time', widget=forms.RadioSelect, null_value=None
        )
        date_range = django_filters.DateFromToRangeFilter(
            label='By Date Range',
            method='filter_by_range',
            widget=RangeWidget(attrs={'class': 'datepicker', 'type': 'date'})
        )

        class Meta:
            model = PartLog
            fields = ['transaction_time', 'date_range']

        def filter_by_range(self, queryset, name, value):
            start = value.start
            end = value.stop
            return queryset.filter(transaction_time__gte=start, transaction_time__lte=end)

My front end:

<div class="filters-div parts-report-filter">
    <form method="get" style="border:1px solid black">
        <p class="filters-header">FILTER</p>
        {{ filter.form.as_p }}
        <button type="submit" id="submit-filter" style="visibility: hidden; height: 1px">Filter</button>
    </form>
</div>

{% block js_load %}
{{ block.super }}
{% endblock %}
{% block js_ready %}
{{ block.super }}

$('#id_time_0').attr("text", "From");
$('#id_time_1').attr("text", "To");

$('.datepicker').first().on("change", function (e) {
if($('.datepicker').last().val()) {
    $('#submit-filter').click();
}
});

$('.datepicker').last().on("change", function (e) {
if($('.datepicker').first().val()) {
    $('#submit-filter').click();
}
});

{% endblock %}

My Views.py:

class LogPartExport(AjaxView):
    model = PartLog

    def get(self, request, *args, **kwargs):

        export_format = request.GET.get('format', 'xls').lower()

        if export_format not in GetExportFormats():
            export_format = 'xls'

        filename = 'InvenTree_part_reports_{date}.{fmt}'.format(
            date=datetime.now(),
            fmt=export_format
        )

        transaction_time = request.GET.get('transaction_time')
        date_range_start = request.GET.get('date_range_min')
        date_range_end = request.GET.get('date_range_max')

        filters = {
            'today': {
                'transaction_time__year': now().year,
                'transaction_time__month': now().month,
                'transaction_time__day': now().day
            },
            'yesterday': {
                'transaction_time__year': (now() - timedelta(days=1)).year,
                'transaction_time__month': (now() - timedelta(days=1)).month,
                'transaction_time__day': (now() - timedelta(days=1)).day,
            },
            'week': {
                'transaction_time__gte': _truncate(now() - timedelta(days=7)),
                'transaction_time__lt': _truncate(now() + timedelta(days=1)),
            },
            'month': {
                'transaction_time__year': now().year,
                'transaction_time__month': now().month
            },
            'year': {
                'transaction_time__year': now().year,
            },
        }

        part_logs = PartLog.objects.all()

        if transaction_time:
            part_logs = part_logs.filter(**filters[transaction_time])
        if date_range_start and date_range_end:
            part_logs = part_logs.filter(transaction_time__gte=date_range_start,
                                         transaction_time__lte=date_range_end)

        dataset = PartLogResource().export(queryset=part_logs)

        filedata = dataset.export(export_format)

        ReportHistory.submit(user=request.user, report_name=filename)

        return DownloadFile(filedata, filename)
