如何在Django中获取UpdateView (创建视图)中的文件名

from django.urls import reverse_lazy
from django.views.generic.edit import UpdateView
from .models import YourModel
from .forms import YourModelForm

class YourModelUpdateView(UpdateView):
    model = YourModel
    form_class = YourModelForm
    template_name = 'your_template.html'
    success_url = reverse_lazy('success_url_name')

    def form_valid(self, form):
        # 获取上传文件的文件名
        uploaded_file = form.cleaned_data['file_field_name']
        file_name = uploaded_file.name
        print(f"Uploaded file name: {file_name}")

        # 继续处理表单
        return super().form_valid(form)
