Download uploaded files from Django Admin

Question

I have uploaded some files in django admin using

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

Now I want to download the same file for which I have written the below function within the class :

def file_link(self):
    request = None
    full_url = ''.join(['http://', get_current_site(request).domain, self.cvFile.url])
    if self.cvFile:
        return "<a href='%s'>download</a>" % (full_url)
    else:
        return "No attachment"

file_link.allow_tags = True

However when I click on the link, it redirects to a page with the link appended to the present url. And since the url doesn't exist, it is showing error.

you can simply do this

Click to get the code

from django.contrib import admin
from app.models import *

class AppAdmin(admin.ModelAdmin):
    list_display = ('author','title','file_link')
    def file_link(self, obj):
        if obj.file:
            return "<a href='%s' download>Download</a>" % (obj.file.url,)
        else:
            return "No attachment"
    file_link.allow_tags = True
    file_link.short_description = 'File Download'

admin.site.register(AppModel , AppAdmin)

You need an absolute url inside href, whereas self.cvFile.url will return a relative url. So unless you are on the home page, the link will simply append on to whatever url you are currently on. Simply add the domain url to self.cvFile.url and it should work.

Hi. Thanks for the reply. Now I declared a new url : full_url = ''.join(['http://', get_current_site(request).domain, self.cvFile.url]). However its still redirecting to the same url as before. – harsh sahay Dec 28 '15 at 07:36
And what is that url? – TheGeorgeous Dec 28 '15 at 07:40
The link to the file appended with the current url. – harsh sahay Dec 28 '15 at 07:46
Seeing the actual url would be helpful – TheGeorgeous Dec 28 '15 at 07:47
http://127.0.0.1:8000/admin/app1/resourcestatic/ is the current url. When I click on the link to the uploaded file the link simply gets appended to it i.e. http://127.0.0.1:8000/admin/app1/resourcestatic/cv/ – harsh sahay Dec 28 '15 at 07:48
Can you update the code in the question to what you are using now? – TheGeorgeous Dec 28 '15 at 07:50
Use `pdb` to make sure the `domain` url and `self.cvFile.url` you get are as intended – TheGeorgeous Dec 28 '15 at 08:13
