Question

views.py

def when(request):
    user = request.user
    report = Report.objects.get(user=request.user)
    reportform = ReportForm(instance=report)   
    settings = Settings.objects.get(user=request.user)
    settingsForm = SettingsForm(instance=settings) 
    settings=Settings.objects.get(user=2)
    if settings.date_format == '0':
        date_filter = 'd/m/Y'
    else:
        date_filter = 'm/d/Y'
    if settings.time_format == '0':
        time_filter = 'I:Mp'
    else:
        time_filter = 'H:M'
    if request.method == 'POST':            
        reportform = ReportForm(instance=report,data=request.POST)
        if reportform.is_valid():
            report = reportform.save(commit=False) 
            report.user = request.user
            report.save()
            return redirect('/member/media/')

    return render_to_response('incident/when.html',{
                  'newreport_menu': True, 
                  'form': reportform,
                  },
                   context_instance=RequestContext(request))

模板是

{{ form.manual_time|date:time_filter }}
{{ form.manual_date|date:date_filter }}

在模板中的date_filter和time_filter中给出错误，错误是“在渲染时捕获VariableDoesNotExist：在['{}}中找到关键[time_filter]的失败，

Answer 1

您尚未在传递给time_filter的上下文词典中添加date_filter或render_to_response。

渲染时捕获VariableDoesNotExist：在u [[{}中查找键[time_filter]失败，
