Serve media files with Django on production server - django

I know you're not technically supposed to do this, but I have no choice, I need to launch my site today. And since this is my first Django app, I just realized that setting DEBUG=False causes media files to no longer be served by Django in production.
What is the quickest and dirtiest way to get Django to serve my media files? Any help is infinitely appreciated!

Here's what I ended up doing. I just added the below to my apache2.conf file and it worked great:
Alias /media/ /home/Mysite/mediaroot/
<Directory /home/Mysite/media>
Order deny,allow
Allow from all
</Directory>
Apache serves my media now :)

There is no quick and dirty way. There is only the way to actually do it: point Apache to the media folder and set STATIC_URL to the URL that Apache is using.

I think I'm confused,
Normally in a production environment I set my static url and media_url to the designated folders on my server.
Then my templates reference,
<img src="{{ MEDIA_URL }}images/image1.jpg" />
My settings file would look like this,
MEDIA_URL = "http://www.noobmovies.com/static/"
and it serves CSS, JavaScript etc...
I'm not sure there is anything dirty or inappropriate about it.

Mapping two MEDIA_URLs to the same MEDIA_ROOT

I’m migrating a website from WordPress to Django/Wagtail. I have all the old WP content in my media directory & it’s all being served appropriately.
It would be convenient to map other URLs (specifically /wp-content/) to MEDIA_ROOT, for the sake of old media URLs that were hardcoded in the content.
So for example a migrated asset now available at //example.com/media/uploads/2017/12/IMG_2120.jpg can also be served from //example.com/wp-content/uploads/2017/12/IMG_2120.jpg
I’m sure there’s some obvious way to do this (in urls.py?) but totally drawing a blank.
I'm sure you already know that static/media files should be served using a frontend server (like Nginx), because it's been mentioned at so many places in the docs.
So, if Django doesn't serve the files, why does it need the MEDIA_ROOT and MEDIA_URL settings?
MEDIA_ROOT is the place where Django stores the images/files you upload.
MEDIA_URL is used by Django to generate file urls. For example, if MEDIA_URL = '/media/', then if you do {{ image.url }}, Django will generate a url like this - /media/image.jpg.
But Django doesn't serve the files. Your frontend server does. So, what you do is, you configure your frontend server like this:
if request path starts with /media/:
map it to <media directory>
Basically, you're telling your frontend server to serve content from the <media directory> for every request that starts with /media/. This way, a request starting with /media/ never actually reaches your Django app, because your server is taking care of them.
What I mean by all this is that you can configure your frontend server to map /wp-content/uploads/ to your <media directory> and it will serve the files.

django 1.6 serving static admin files using alias with apache

So I am converting the Django tutorial to fully work with Apache instead of using the built-in "runserver" command. I got step one working; getting Apache to serve the static files (css). Now I need to get it to serve the static files for the admin.
My code so far in the httpd.conf file for Apache 2.4.
#static files for site
Alias /static/ "C:/mysite/polls/static/"
<Directory "C:/mysite/polls/static">
Require all granted
</Directory>
#static files for admin
Alias /static/ "C:/Python27/Lib/site-packages/django/contrib/admin/static/"
<Directory "C:/Python27/Lib/site-packages/django/contrib/admin/static">
Require all granted
</Directory>
Obviously having the same alias for the 2nd block does not work and the CSS will not load for the admin. The site (1st block) loads fine. Now this page in the Django tutorial details the entire process on how to make it work. I just cannot figure it out. Maybe I am doing a syntax error and I have read countless posts about this both here and elsewhere.
The doc mentions 3 ways to do it. I want to do it the 2nd way; by way of using the alias directive: "Use an Alias directive, as demonstrated above, to alias the appropriate URL (probably STATIC_URL + admin/) to the actual location of the admin files."
Now I don't understand the exact part where it says "STATIC_URL + admin/). I tried various variations of that but it won't work. My link to the admin page is exactly this:
http://127.0.0.1/admin/
Can we figure this out in specific to WINDOWS and DJANGO 1.6? I know prior to DJANGO 1.4 there was a different way using "ADMIN_MEDIA_PREFIX" in the settings.py file. That way is deprecated now and I want to use the alias. And bonus. How do aliases exactly work?
Thanks all.
EDIT:
Link that mentions how to do it. Under "Serving the admin files" I need to figure out the 2nd way using alias.
https://docs.djangoproject.com/en/1.6/howto/deployment/wsgi/modwsgi/
This is what the "static" app is for. You should do manage.py collectstatic on deployment, and this collects all your static content - both for your apps and for the built-in/contrib ones - into one place, which is where you point your Apache alias to.
But if you really want to hard code it, STATIC_URL + admin just means exactly that: the value of STATIC_URL, suffixed with "admin", so Alias /static/admin.
This is the code that finally works:
Alias /static/admin "C:/Python27/Lib/site-packages/django/contrib/admin/static/admin/"
<Directory "C:/Python27/Lib/site-packages/django/contrib/admin/static/admin">
Require all granted
</Directory>
Alias /static/ "C:/mysite/polls/static/"
<Directory "C:/mysite/polls/static">
Require all granted
</Directory>
Note that ORDER matters greatly. I have to Alias the admin static BEFORE aliasing the site static. Sounds like a cascading type issue and makes sense the more specific gets precedent.
Also I had my link incorrect for the admin. It was ending in ../admin/static/. It should go deeper into ../admin/static/admin/.
Finally 2 areas working to serve static files. The admin comes first and then the site static 2nd.
Thanks to all and this should be really documented and might be a pitfall for some.

Django - admin_media_prefix access from javascript

In the admin, I would like the admin media url to be accessible from any javascript.
I already have it included in the request context.
But in order to be able to access it from an included javascript,
<script type="text/javascript">
window.__admin_media_prefix__ = "{{ ADMIN_MEDIA_URL }}";
</script>
Do I have to put something like that in a base template or is there a cleaner way to do that ?
Media (static) files are not interpreted by django in any way. On a production site python code might not even have an access to that files, as they are probably served by the frontend webserever. So you have a crazy option: use something like server side includes (SSI) to embed the variable content into choosen media files by somehow parsing the config file.
Better idea would be to have same admin media prefix scheme for every site, flexible per-site config file for your webserver of choice, where admin media files would be served from some known location:
location ^~ /media/ {
root /.../django-$django_ver/contrib/admin/;
}
I can provide a somewhat "evil" solution: since Django 1.4 django.contrib.admin is using django.contrib.staticfiles for everything static. Since Admin's Javascript is using missing-admin-media-prefix if it's not found, we can do a redirect, e.g. in Apache:
RewriteRule ^/missing-admin-media-prefix/(.*)$ /static/admin/$1 [L,R=301]
(if your STATIC_URL is set to /static, of course)
This method is especially nice if you hack around stuff in Admin a lot and also don't want to clutter your templates with global Javascript variable declarations.

Django moving from Development server to Deployment Server

Regarding this documentation page from the Django website,
https://docs.djangoproject.com/en/1.2/howto/static-files/
where it says for development "With that said, Django does support static files during development. You can use the django.views.static.serve() view to serve media files."
So my question is, if I use this method, How much work is required to move to apache.
Currently I have a symbolic link to my image folder in the /var/www folder, and in the Django settings I have set the media url to :
MEDIA_URL = 'http://127.0.0.1:80/Images/'
This seems like a fairly easy hack but my project is going to get very big (with lots of css, js and pdfs) and I doubt if this method is good.
My approach was to have apache itself intercept the static files urls and serve them directly without invoking django at all. So my apache config looked something like this:
<VirtualHost *:80>
ServerName www.myproject.com
Alias /static /docs/my_website/static
<Directory /docs/my_website/static>
Order allow,deny
Allow from all
</Directory>
Alias /favicon.ico /docs/my_website/static/images/icons/favicon.ico
Include "/13parsecs/conf/django.conf"
</VirtualHost>
Then you can just keep doing whatever you're doing in the dev environment, and when you get to apache it won't invoke django at all for static content, which is what you want.
This is a perfectly good way of doing things. The only change you'll need to make is to put the actual URL of your site, rather than the localhost IP.
Don't "move to Apache", start using it in the first place. None of the software needed has licensing fees and runs on almost any platform, so the only excuse you could have is "I'm too lazy".

Serving static media in django application

I notice that when I reference my java scripts and static image files from my templates, they show up in development, but not from the production server. From development, I access them as such:
<img src="/my_proj/media/css/images/collapsed.png" />
but from production, I have to remove the project directory:
<img src="/media/css/images/collapsed.png" />
I'm assuming I'm doing something wrong with regard to serving static media.
I'm caught between a number of seemingly different options for serving static media in Django. On one hand, it's been recommended that I use django-staticfiles to serve media. On the other I see reference to STATIC_ROOT and STATIC_URL in the documentation (with caveats about use in production).
I have small .png files of "plus" and "minus" symbols for use in some of my jQuery scripts. In addition, the scripts themselves need to be referenced.
1) Am I correctly categorizing scripts and site images as static media?
2) What is the best method to access this media (from production)?
You shouldn't keep the URLs hardcoded that way.
If you're running thedev version of Django, you should check this doc.
If you're not, for simplicity, you can use {{ MEDIA_URL }} and configure that variable in your settings for dev and for production.
<img src="{{ MEDIA_URL }}/media/css..." />
Keep in mind that you'll have to use RequestContext, see more here on docs here and here.
Also, you should server all your static files directly trough a proper webserver. You can configure apache or nginx to do that.
Sigh. There is only one way to serve static media in production, and that is to get the webserver - eg Apache - to do it. Django-staticfiles is for development only, and this is clearly stated throughout the documentation.
