How to use Django to get the name for the host server?

Question

I need the name of the hosting server instead of the client name?

I can't believe this process is so convoluted in Dj. – zallarak Dec 17 '14 at 01:29 — zallarak, Dec 17 '14 at 01:29

I generally put something like this in settings.py:

import socket

try:
    HOSTNAME = socket.gethostname()
except:
    HOSTNAME = 'localhost'

Your solution does not work, if you use Docker. It will show the container ID instead of the URL. – Özer Nov 18 '16 at 09:57

His solution was written before docker existed. Sorry. – antony.trupe Nov 02 '20 at 18:05

If you have a request (e.g., this is inside a view), you can look at request.get_host() which gets you a complete locname (host and port), taking into account reverse proxy headers if any. If you don't have a request, you should configure the hostname somewhere in your settings. Just looking at the system hostname can be ambiguous in a lot of cases, virtual hosts being the most common.

In case i don't have a request, I need to hard-code domain name in settings variable? – Yukulélé Nov 26 '18 at 09:48
for me `request.get_raw_uri()` did the job, as it also provided the protocol http(s). This is in Django 3 though, not sure when this was introduced. – Donald Mar 29 '20 at 19:56

Just add to @Tobu's answer. If you have a request object, and you would like to know the protocol (i.e. http / https), you can use request.scheme (as suggested by @RyneEverett's comment).

Alternatively, you can do (original answer below):

if request.is_secure():
    protocol = 'https'
else:
    protocol = 'http'

Because is_secure() returns True if request was made with HTTPS.

Couldn't you just use [request.scheme](https://docs.djangoproject.com/en/dev/ref/request-response/#django.http.HttpRequest.scheme)? – Ryne Everett Jul 21 '15 at 20:28

If you need to get http(s)://hostname/ you can use the following:

request.build_absolute_uri('/')

When using this, be aware that some distro's only set HOST, while others only set HOSTNAME, and that many *export* neither by default. – BrtH Apr 21 '21 at 23:59

Basically, You can take with request.get_host() in your view/viewset. It returns <ip:port>

If you have a request object, you can use this function:

def get_current_host(self, request: Request) -> str:
    scheme = request.is_secure() and "https" or "http"
    return f'{scheme}://{request.get_host()}/'

Is there any reason not to simplify this into `f"{request.scheme}://{request.get_host()}/"`? – trpropst Mar 10 '21 at 22:06
From docs: A string representing the scheme of the request (http or https usually). So this might be even easier. – Tobias Ernst Mar 11 '21 at 09:56

While this code may solve the question, [including an explanation](//meta.stackexchange.com/q/114762) of how and why this solves the problem would really help to improve the quality of your post, and probably result in more up-votes. Remember that you are answering the question for readers in the future, not just the person asking now. Please [edit] your answer to add explanations and give an indication of what limitations and assumptions apply. – Suraj Rao Sep 30 '21 at 08:32

`REMOTE_ADDR` is usually the IP address of the client. The only time that is going to be the host server is if the request is made from localhost. – Stephen Ostermiller Nov 01 '21 at 07:35
