如何在 Django 视图中下载文件字段文件 [英] how to download a filefield file in django view

问题描述

我的 Django 模型中有文件字段:

I have filefield in my django model:

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

该文件将显示在带有链接http://test.com.cn/home/projects/89/attachment/2012/02/24/sscsx.txt"的网页中

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

我想要做的是当用户点击文件链接时，它会自动下载文件；谁能告诉我如何在视图中执行此操作?

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?

提前致谢！

推荐答案

你可以试试下面的代码，假设 object_name 是那个模型的对象:

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内容，请参阅 Django 文档的以下部分:https://docs.djangoproject.com/en/dev/ref/request-response/#telling-the-browser-to-treat-响应作为文件附件

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
