如何传递django forms.SplitDateTimeField的值？

from django import forms

class MyForm(forms.Form):
    my_datetime = forms.SplitDateTimeField()

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            # 处理有效的表单数据
            my_datetime_value = form.cleaned_data['my_datetime']
            # 其他操作...
    else:
        form = MyForm()
    return render(request, 'my_template.html', {'form': form})

<form method="post">
    {% csrf_token %}
    {{ form.my_datetime.label_tag }}: {{ form.my_datetime }}
    <input type="submit" value="Submit">
</form>
