如何在 Django Admin 的 FileField 中显示附件的下载链接? [英] How to show download link for attached file in FileField in Django Admin?

问题描述

我的 django 模型中有 FileField:

I have FileField in my django model:

file = models.FileField(upload_to=FOLDER_FILES_PATH)

在用于更改此模型的 Django 管理部分中，我有此文件的完整路径(默认情况下):

In Django admin section for changing this model I have full path to this file (by default):

Currently: /home/skyfox/Projects/fast_on_line/order_processor/orders_files/mydog2_2.jpg 

如何为我的管理面板用户显示下载此文件的链接?

How can I show link for downloading this file for my admin panel users?

推荐答案

例如，如果你有一个模型案例"，你可以在你的类中添加一个方法来创建"上传文件的链接:

If you have a model "Case" for example, you could add a method to your class which "creates" the link to the uploaded file :

class Case(models.Model)
    ...
    file = models.FileField(upload_to=FOLDER_FILES_PATH)
    ...

    def file_link(self):
        if self.file:
            return "<a href='%s'>download</a>" % (self.file.url,)
        else:
            return "No attachment"

    file_link.allow_tags = True

然后，在你的 admin.py 中

then, in your admin.py

list_display = [..., file_link, ...]
