Individual start date (via get_initial()) for report not honored in dashboard widget

[wherget]

I have this sort of report:

class SampleYearlyReport(ReportView):
    report_title = "Example"
    report_model = Example
    date_field = "start_date"
    time_series_pattern = "annually"
    time_series_columns = [
        ComputationField.create(Count, "id", "count", "Count")
    ]

    columns = [
        "__time_series__",
    ]

    chart_settings = [
        Chart(
            "Count",
            Chart.BAR,
            data_source=["count"],
            title_source=["count"],
        )
    ]

    def get_initial(self):
        default = super().get_initial()
        default["start_date"] = datetime.datetime(
            datetime.date.today().year - 3, 1, 1, 0, 0, 0
        )
        return default

Where since this is a yearly report, I obviously want it to start a good deal earlier than the default "1st January of this year" (which is fine for other reports). This works fine in a plain old report view, but breaks in a dashboard.

AFAICS, this is due to

django-slick-reporting/slick_reporting/forms.py

Lines 152 to 156 in a303284

	def get_start_date(self):
	return self.cleaned_data.get("start_date")
	def get_end_date(self):
	return self.cleaned_data.get("end_date")

As for a dashboard widget, there will be no cleaned_data, since it doesn't take a round trip via the rendered form. Should the ReportForm be trying to get the start_date from initial_data if there is none in cleaned data?

Do you (again) have a good idea where to monkey-patch this in? I'm not yet ready to write a complete custom form (although that will happen in the future, especially to integrate a date picker, but for now...), so ideally I could keep using report_form_factory.

Well, thanks for rubber ducking, GitHub. My current workaround is this:

    def get_form_class(self):
        base_form_class = super().get_form_class()  # uses report_form_factory
        class PatchedDates(base_form_class):
            def get_start_date(self):
                return self.cleaned_data.get("start_date") or self.initial.get("start_date")

            def get_end_date(self):
                return self.cleaned_data.get("end_date") or self.initial.get("end_date")

        return PatchedDates
