Invalid FileField Admin URL

Question

In the Django admin, wherever I have FileField, the edit page has a “current” window with a hyperlink to the current file. However, this link is added to the current URL of the page and, therefore, leads to 404, since there is no such page, such as: http://127.0.0.1:8000/admin/Tank/asset/17/media/datasheet/13/09/05/copyright.html/
For reference, the correct file URL is: http://127.0.0.1:8000/media/datasheet/13/09/05/copyright.html

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

Answer 1

settings.py

add lines:

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

replace strings:

 MEDIA_ROOT = '' MEDIA_URL = '' 

from

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

this should set up your project to display media content from the folder / of your project directory / media /

urls.py

also add the line:

 import settings 

add the following line to url patterns:

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

models.py

inside your model add the following line:

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

define a method in a model

 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

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

eg,

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

Answer 2

The answer to this question is covered in some detail by this answer . In short, however, the problem is that you probably did not configure your MEDIA_ROOT and MEDIA in settings.py and in urls.py you did not do this so that the media folder is loaded.
