Django下载文件
我是使用Django的新手,我正在尝试开发一个网站,用户可以在其中上传许多excel文件,然后将这些文件存储在媒体文件夹Webproject / project / media中。
def upload(request): if request.POST:
form = FileForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return render_to_response('project/upload_successful.html')
else:
form = FileForm()
args = {}
args.update(csrf(request))
args['form'] = form
return render_to_response('project/create.html', args)
然后,该文档会与它们上载的任何其他文档一起显示在列表中,你可以单击这些文档,它会显示有关它们的基本信息以及他们上载的excelfile的名称。从这里,我希望能够使用链接再次下载相同的excel文件:
<a href="/project/download"> Download Document </a>
我的网址是
urlpatterns = [ url(r'^$', ListView.as_view(queryset=Post.objects.all().order_by("-date")[:25],
template_name="project/project.html")),
url(r'^(?P<pk>\d+)$', DetailView.as_view(model=Post, template_name="project/post.html")),
url(r'^upload/$', upload),
url(r'^download/(?P<path>.*)$', serve, {'document root': settings.MEDIA_ROOT}),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
但我得到了错误,serve()得到了一个意外的关键字参数’document root’。谁能解释如何解决此问题?
要么
解释如何获取上传的文件以进行选择和使用
def download(request): file_name = #get the filename of desired excel file
path_to_file = #get the path of desired excel file
response = HttpResponse(mimetype='application/force-download')
response['Content-Disposition'] = 'attachment; filename=%s' % smart_str(file_name)
response['X-Sendfile'] = smart_str(path_to_file)
return response
回答:
你错过了参数文档_ root 下划线。但是serve
在生产中使用它是个坏主意。使用类似这样的东西:
import osfrom django.conf import settings
from django.http import HttpResponse, Http404
def download(request, path):
file_path = os.path.join(settings.MEDIA_ROOT, path)
if os.path.exists(file_path):
with open(file_path, 'rb') as fh:
response = HttpResponse(fh.read(), content_type="application/vnd.ms-excel")
response['Content-Disposition'] = 'inline; filename=' + os.path.basename(file_path)
return response
raise Http404
