how to download a filefield file in django view

I have filefield in my django model:

class MyModel(Model):
    file = models.FileField(upload_to='attachment/%Y/%m/%d',max_length=480)

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

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?

Thanks in advance!

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

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