I am really getting to the end of my tether with `django-hosts` I want to redirect [cerulix.com/blog](http://cerulix.com/blog) → [blog.cerulix.com](http://blog.cerulix.com). But apparently that’s way too much of an ask. **Here’s my MRE:** I install the `django-hosts` module in my `.venv` by running the following command: `pip install django-hosts` ```auto #settings.py MIDDLEWARE = [ 'django_hosts.middleware.HostsRequestMiddleware', 'django_hosts.middleware.HostsResponseMiddleware', ] INSTALLED_APPS = [ 'blog', 'django_hosts' ] ALLOWED_HOSTS = [ '127.0.0.1', 'cerulix.com', 'www.cerulix.com', 'blog.cerulix.com', ] ROOT_HOSTCONF = "cerulix.hosts" DEFAULT_HOST = "www" PARENT_HOST = 'cerulix.com' ``` ```auto #cerulix.hosts from django_hosts import patterns, host from django.conf import settings from django.urls import path, include host_patterns = patterns('', host(r'www', settings.ROOT_URLCONF, name='www'), host(r'blog', 'blog.urls', name='blog') ) ``` ```auto #cerulix.urls from . import views from django.conf import settings from django.conf.urls.static import static from django.views.static import serve urlpatterns = [ path('', views.index), path('blog', include('blog.urls'), name='blog'), ] ``` ```auto #blog.urls from django.urls import path from. import views urlpatterns = [ path('', views.blog, name='blog'), path('', views.blog__details), ] ``` ```auto #index.html {% load hosts %} Blog ``` As you can see, everything is set up correctly. Guess what? - You type `blog..com` into the URL, → `index.html` - You go to the `blog` ` ### Author: ![philgyford](https://sea2.discourse-cdn.com/flex026/user_avatar/forum.djangoproject.com/philgyford/32/14295_2.png) [@philgyford](https://forum.djangoproject.com/u/philgyford) #### Post date: [August 6, 2025, 7:53am UTC](https://forum.djangoproject.com/t/django-hosts-not-routing-subdomains-correctly-despite-correct-configurations/42255/2 "2025-08-06T07:53:52Z") > [@BlauweStadTechnologi](#): > > I want to convert [cerulix.com/blog](http://cerulix.com/blog) → [blog.cerulix.com](http://blog.cerulix.com). What do you mean by “convert”? Do you mean redirect? If so, that doesn’t appear to be what django -hosts is for. It allows you to route requests for different hosts to different urlconf files. That’s it. > [@BlauweStadTechnologi](#): > > You go to the `blog` `Blog` You’re generating a link to the “blog” page on the host “blog”.

Yup, by “convert" I mean, redirect. I will reword. > It allows you to route requests for different hosts to different urlconf files. That’s it. That’s exactly what `django-hosts` are used for. It says in the official documentation, & it’s not doing what I have told it to do, I have told it go to the blog section & display `blog.cerulix.com` in the URL bar in the browser, just like every other website in the world that uses subdomains. The other links I am clicking on AFTER I have visited the blog page, which django clearly seems to have an identity crisis over, are not hosted by the `host_url` tag - because they are hosted by the `urls` tag. It’s how it worked before `django-hosts` because the insanity of my life and now the browser is having a hissy fit over it. Is this thing a django module or a baby? Just every little thing, there’s an issue with it. Issue after error after issue after error after issue. I am so sick and tired of it. Why can’t something just do what I tell it to without arguing with me? Why do I have to waste my time, scream, rip my hair out just because this module decides when it is going to do as it’d told? ---

> [@BlauweStadTechnologi](#): > > Yup, by “convert" I mean, redirect. I will reword. Then django-hosts is not what you need. It doesn’t redirect a request for one URL to another URL. It routes requests to urlconf files (and so URLs) based on the domain name. Without redirecting the browser to a new URL. > [@BlauweStadTechnologi](#): > > Yup, by “convert" I mean, redirect.

It looks at what is in the URL bar and serves a view depending on which domain is in that URL bar. That’s it. > [@BlauweStadTechnologi](#): > > The other links I am clicking on AFTER I have visited the blog page, which django clearly seems to have an identity crisis over, are not hosted by the `host_url` tag - because they are hosted by the `urls` tag. So, if you look at the source of the page in your browser, you’ll see that those links are like `/blog/foo/`. i.e. they do not have `https://` at the start. Therefore they will go to that URL on the same domain as the current page. If you want them to go to a different domain, you’ll have to use the `host_url` tag. > [@BlauweStadTechnologi](#): > > The other links I am clicking on AFTER I have visited the blog page, which django clearly seems to have an identity crisis over, are not hosted by the `host_url` tag - because they are hosted by the `urls` tag. You need to take a step back, understand how browsers, URLs and redirections work, understand the documentation for the tools you’re using, and quit blaming everything else for things not working when you haven’t set them up properly, or are using the wrong tools. ---

You’ve “told it” to do something it wasn’t designed to do.
