我的Django模型中有filefield:

I have filefield in my django model:

file=models.FileField(verbose_name=u'附件',upload_to='attachment/%Y/%m/%d',max_length=480)

此文件将显示在网页中，链接为"test/home/projects/89/attachment/2012/02/24/sscsx.txt"

This file will display in the web page with link "test/home/projects/89/attachment/2012/02/24/sscsx.txt"

我想要做的是当用户单击文件链接时，它将自动下载文件； 谁能告诉我该怎么做?

What I want to do is when user click the file link, it will download the file automatically; Can anyone tell me how to do this in the view?

提前谢谢！

推荐答案

您可以尝试以下代码，假设object_name是该模型的对象:

You can try the following code, assuming that object_name is an object of that model:

filename = object_name.file.name.split('/')[-1] response = HttpResponse(object_name.file, content_type='text/plain') response['Content-Disposition'] = 'attachment; filename=%s' % filename return response

有关直接发送文件的信息，请参阅Django文档的以下部分: docs.djangoproject/en/dev/ref/request-response/#telling-the-browser-to-treat将响应作为文件附件

See the following part of the Django documentation on sending files directly: docs.djangoproject/en/dev/ref/request-response/#telling-the-browser-to-treat-the-response-as-a-file-attachment
