在django change视图中添加下载功能

from django.urls import path
from . import views

urlpatterns = [
    path('download/<int:pk>/', views.download_file, name='download'),
]

from django.http import HttpResponse
from django.shortcuts import get_object_or_404
from django.conf import settings
import os

def download_file(request, pk):
    file_path = get_object_or_404(FileModel, pk=pk).file.path  # 从数据库获取文件路径或文件对象
    file_name = os.path.basename(file_path)  # 获取文件名

    with open(file_path, 'rb') as file:
        response = HttpResponse(file.read(), content_type='application/octet-stream')
        response['Content-Disposition'] = f'attachment; filename="{file_name}"'  # 设置响应头，指定文件名

    return response

<a href="{% url 'download' object.pk %}">下载</a>
