使用FileField编辑表单将删除该文件

from django import forms

class MyForm(forms.Form):
    file = forms.FileField()

from django.shortcuts import render
from .forms import MyForm
import os

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST, request.FILES)
        if form.is_valid():
            # 保存表单数据
            form.save()

            # 删除文件
            file_path = form.cleaned_data['file'].path
            os.remove(file_path)

            return render(request, 'success.html')
    else:
        form = MyForm()

    return render(request, 'my_form.html', {'form': form})
