优雅地从Django中的URL生成日期时间？

from django.shortcuts import render
from datetime import datetime

def my_view(request):
    current_datetime = datetime.now()
    return render(request, 'my_template.html', {'current_datetime': current_datetime})

<p>当前日期时间：{{ current_datetime|date:"Y-m-d H:i:s" }}</p>

<a href="{% url 'my_view' %}?datetime={{ current_datetime|date:"Y-m-d+H:i:s" }}">生成日期时间</a>

from django.shortcuts import render
from datetime import datetime

def my_view(request):
    datetime_str = request.GET.get('datetime', None)
    if datetime_str:
        datetime_obj = datetime.strptime(datetime_str, '%Y-%m-%d+%H:%M:%S')
    else:
        datetime_obj = datetime.now()
    return render(request, 'my_template.html', {'current_datetime': datetime_obj})
