Django:如何重定向到表单来源的页面

from django.http import HttpResponseRedirect

def your_view(request):
    if request.method == 'POST':
        # 处理表单数据
        form = YourForm(request.POST)
        if form.is_valid():
            # 保存表单数据
            form.save()
            # 获取表单来源的页面 URL
            redirect_url = request.POST.get('next', '/default_redirect_url/')
            # 重定向到表单来源的页面
            return HttpResponseRedirect(redirect_url)
    else:
        form = YourForm()
    return render(request, 'your_template.html', {'form': form})
