管理员FileField当前网址不正确 [英] Admin FileField current url incorrect

问题描述

在Django管理员中，无论我有一个FileField，在编辑页面上都有一个当前"框，其中包含指向当前文件的超链接.但是，此链接被附加到当前页面的URL，因此由于没有这样的页面，因此将导致404，例如: http://127.0.0.1:8000/admin/Tank/asset/17/media/datasheet/13/09/05/copyright.html/
作为参考，文件的正确网址是: http://127.0.0.1:8000/media/datasheet/13/09/05/copyright.html

In the Django admin, wherever I have a FileField, there is a "currently" box on the edit page, with a hyperlink to the current file. However, this link is appended to the current page url, and therefore results in a 404 as there is no such page as, for example: http://127.0.0.1:8000/admin/Tank/asset/17/media/datasheet/13/09/05/copyright.html/
For reference, the correct url of the file is: http://127.0.0.1:8000/media/datasheet/13/09/05/copyright.html

有没有办法解决默认管理员布局中的此问题?它会影响数据库中的每个FileField，在我看来，这就像一个错误.我只是用错了吗?

Is there any way to fix this problem in the default admin layout? It affects every FileField in my database, and seems to me like a bug. Am I just using it wrong?

推荐答案

settings.py

添加行:

import os
BASE_DIR = os.path.realpath(os.path.dirname(__file__))

替换行:

MEDIA_ROOT = ''
MEDIA_URL = ''

使用

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR,os.pardir,'media')

这应该设置您的项目以呈现文件夹/your project directory/media/

this should setup your project to render your media content from the folder /your project directory/media/

还添加以下行:

import settings

在您的网址格式中添加以下行:

add the following line in your url patterns:

url(r'^media/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT, 'show_indexes': False}),

models.py

在模型内部添加以下行:

models.py

inside your model add the following line:

File = models.FileField('File',upload_to='./')

定义模型中的方法

def fileLink(self):
    if self.File:
        return '<a href="' + str(self.File.url) + '">' + 'NameOfFileGoesHere' + '</a>'
    else:
        return '<a href="''"></a>'
fileLink.allow_tags = True
fileLink.short_description = "File Link"

admin.py

使用字段 fileLink 作为只读字段，您也可以将其添加到 list_display

admin.py

use the field fileLink as a read only field, you can also add it to your list_display

例如

class FileAdmin(admin.ModelAdmin):
    list_display = ['fileLink']
    readonly_fields = ['fileLink']
