I need to have multiple sub domains for my project. Each sub domain represents some company. For example: company1.myproject.io, company2.myproject.io. I used django-hosts library to set up sub domains.
hosts file:
127.0.0.1 localhost 127.0.0.1 myproject.io 127.0.0.1 www.myproject.io 127.0.0.1 company1.myproject.io 127.0.0.1 company2.myproject.io
settings.py:
ROOT_URLCONF = 'core.urls' ROOT_HOSTCONF = 'core.hosts' DEFAULT_HOST = 'www' DEFAULT_REDIRECT_URL = "http://www.myproject.io:8000"
core/hosts.py:
from hostsconf import urls as redirect_urls host_patterns = [ host(r'www', settings.ROOT_URLCONF, name='www'), host(r'(?!www).*', redirect_urls, name='wildcard'), ]
hostsconf/urls.py:
from .views import wildcard_redirect urlpatterns = [ url(r'^(?P<path>.*)', wildcard_redirect) ]
hostsconf/views.py:
DEFAULT_REDIRECT_URL = getattr(settings, "DEFAULT_REDIRECT_URL", "http://www.myproject.io:8000") def wildcard_redirect(request, path=None): new_url = DEFAULT_REDIRECT_URL if path is not None: new_url = DEFAULT_REDIRECT_URL + "/" + path return HttpResponseRedirect(new_url)
I have a few problems now:
- When I go to myproject.io it succesfully redirects me to the www.myproject.io. But when I go to company1.myproject.io I got an
Invalid HTTP_HOST header: 'company1.myproject.io:8000'. You may need to add u'company1.myproject.io' to ALLOWED_HOSTS
Do I really need each time add new host to ALLOWED_HOSTS when I got new sub domain or I am doing something wrong? How to implement a single view for all sub-domains where will be dynamic context for each company. Basically I need to make queries into the db by sub domain name. Example:
def home_page(request): subdomain = 'somehow get sub domain (company1 or company2)' comp = User.objects.get(domain_name=subdomain) return redirect(request, 'tpl.html', {"company": comp})
UPDATE: Figured out how to handle ALLOWED_HOSTS and get a subdomain. But I still don’t get how to implement single view for my sub domains. Do I need to create another pattern in hosts.py?

A value beginning with a period can be used as a subdomain wildcard: ‘.example.com’ will match example.com, www.example.com, and any other subdomain of example.com. https://docs.djangoproject.com/en/1.11/ref/settings/#allowed-hosts
For security purposes you must add your domains to allowed_hosts list. Just use wildcard like this:
ALLOWED_HOSTS = ['.myproject.io']
2) Try HttpRequest.META[“HTTP_HOST”]
https://docs.djangoproject.com/en/1.11/ref/request-response/#django.http.HttpRequest.META
or request.get_host()
UPDATE: If you want operate with multiple sites in single django application, you should use Django Sites framework. You don’t need django-hosts library.
