python - 在Django中上传图片

Question

我正在为网站编写一个简单的文件上传器。用户看到一个表格:

<form action="/user_profileform/" method="POST" enctype="multipart/form-data" name="uform" id="userform">{% csrf_token %}
{{form}}

<input type="submit" value="submit" name="usubmit">
</form>

提交后，我重定向到此函数:

@csrf_exempt
def upload_file(request):
    if request.method == 'POST':
    print "arun";
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            handle_uploaded_file(request.FILES['file'])
            return HttpResponseRedirect('/user_profileform/')
    else:
    print "ranjeet"
        form = UploadFileForm()
    return render_to_response('user_profile.html', {'form': form })

def handle_uploaded_file(f):
    destination = open(settings.MEDIA_ROOT, 'wb+')
    for chunk in f.chunks(): 
        destination.write(chunk)
    destination.close()

当我尝试此功能时，总是会遇到异常:

IOError位于/user_profileform/

[Errno 21]是目录:“/home/ghrix/ghrixbidding/media/images/”

Answer 1

您正在尝试打开目录的settings.MEDIA_ROOT。
