しばらく壁に頭をぶつけていましたが、誰かが助けてくれるかもしれません。これは、Django フォームと日時形式に関するものです。

そのため、日時要素を含むユーザーから情報を取得するフォーム ビューを作成しようとしています。私の見解は次のとおりです。

def index(request):
un = request.user.username
plot, created = PreciseRequest.objects.get_or_create( user_name=un )
if request.method == 'POST':
  form = PreciseForm(request.POST)
    if form.is_valid():
        plot.user_name = form.cleaned_data['user_name'],
        plot.analyte_choice = form.cleaned_data['analyte_choice'],
        plot.plot_format = form.cleaned_data['plot_format'],
        plot.start_datetime = form.cleaned_data['start_datetime'],
        plot.end_datetime = form.cleaned_data['end_datetime'],
        plot.inoculation_start = form.cleaned_data['inoculation_start'],
        plot.inoculation_end = form.cleaned_data['inoculation_end'],
        plot.time_interval_value = form.cleaned_data['time_interval_value'],
        plot.time_interval_type = form.cleaned_data['time_interval_type'],
        plot.auto_glycerol = form.cleaned_data['auto_glycerol'],
        plot.min_glycerol = form.cleaned_data['min_glycerol'],
        plot.max_glycerol = form.cleaned_data['max_glycerol'],
        plot.auto_methanol = form.cleaned_data['auto_methanol'],
        plot.min_methanol = form.cleaned_data['min_methanol'],
        plot.max_methanol = form.cleaned_data['max_methanol'],
        plot.auto_od = form.cleaned_data['auto_od'],
        plot.min_od = form.cleaned_data['min_od'],
        plot.max_od = form.cleaned_data['max_od']
        plot.save( )
    else:
      plot_data = {
        'user_name': plot.user_name,
        'analyte_choice': plot.analyte_choice,
        'plot_format': plot.plot_format,
        'start_datetime': plot.start_datetime,
        'end_datetime': plot.end_datetime,
        'inoculation_start': plot.inoculation_start,
        'inoculation_end': plot.inoculation_end,
        'time_interval_value': plot.time_interval_value,
        'time_interval_type': plot.time_interval_type,
        'auto_glycerol': plot.auto_glycerol,
        'min_glycerol': plot.min_glycerol,
        'max_glycerol': plot.max_glycerol,
        'auto_methanol': plot.auto_methanol,
        'min_methanol': plot.min_methanol,
        'max_methanol': plot.max_methanol,
        'auto_od': plot.auto_od,
        'min_od': plot.min_od,
        'max_od': plot.max_od
    }
    form = PreciseForm( initial=plot_data )
context = Context({ 'title':'Create a Precise Plot', 'form':form })
return render_to_response('PrecisePlot/index.html',context)

        return HttpResponseRedirect( 'ViewPlot/%s/' % plot.id )

次のエラーが表示されます。datetime オブジェクトを間違って渡しているようです。

[u"'(datetime.datetime(2013, 1, 1, 14, 44, 27),)' 値の形式が無効です。YYYY-MM-DD HH:MM[:ss[.uuuuuu]] でなければなりません[TZ] 形式。"]

どんな助けでも大歓迎です、ありがとう！
