如何将转换后的日期和时间格式(即日期和时间变量)传递到窗体。我在窗体中指定的格式现在正在显示，但取决于视图的条件，时间和日期格式应在窗体域中更改。

谢谢

尝试用此行创建表单：

1	reportform = ReportForm(instance=report,initial={'manual_date':date, 'manual_time':time})

其中，date变量是日期格式。您将不得不向下移动表单的实例化。这是您的代码：

def when(request):
user = request.user
report = Report.objects.get(user=request.user)

settings = Settings.objects.get(user=request.user)
settingsForm = SettingsForm(instance=settings)
# settings=Settings.objects.get(user=2)
if settings.date_format == '0':
date = report.manual_date.strftime('%d/%m/%Y')
else:
date = report.manual_date.strftime('%m/%d/%Y')
if settings.time_format == '0':
time = report.manual_time.strftime('%I:%M%p')
else:
time = report.manual_time.strftime('%H:%M')
if request.method == 'POST':
reportform = ReportForm(instance=report,data=request.POST,initial={'manual_date': date,'manual_time': time})
if reportform.is_valid():
report = reportform.save(commit=False)
report.user = request.user
report.save()
return redirect('/member/media/')

reportform = ReportForm(instance=report,initial={'manual_date':date, 'manual_time':time})
return render_to_response('incident/when.html',{
'newreport_menu': True,
'form': reportform,
'date':date,
'time':time,
},
context_instance=RequestContext(request))

。

它试图手动设置在实例化表单时已经格式化的表单的初始值。

希望有帮助！

您可以使用模板标记/筛选日期。在视图级别定义它并传递到模板：

1
2
3
4

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'

在模板中：

1 2	{{ form.manual_date\|date:date_filter }} {{ form.manual_time\|date:time_filter }}

我不确定当前的格式，但您可以随时检查引用以获得所需的内容。

也许视图不是放置此代码的最佳位置。最好创建单独的函数来处理这个问题。
