hello I want to use slug of object as a subdomain for DetailView like in this site https://install-download.net/ (choose one item and see url path) How can I do it?

Try this for url: path('<slug:slug>', views.xyz.as_view(), name='abc'), In models.py, use get_absolute_url() method and render it in your template navigation.

Hi All Im beginner, from where I should start Django.

Hi All Im beginner, from where I should start Django.

I need that slug is not in example.com/first, but first.example.com

Is it deployment or development server? Your question is not detailed enough

I have a simple site with some pages I want to create subdomains in Django admin and depend on subdomains change info on site. For example, in url example.com/page1 title is "Title 1", while in url floor.example.com/page1 title is "Title 2" so I think that I should create subdomain model and page model, connect them by Foreign Key and depend on subdomain show necessary page now I'm working locally

You can talk about subdomain during deployment depending on the hosting platform you choose. Work on your slug at the development environment with urls.py e.g path(''/<slug:slug>, .....)

so in localhost it will show example.com/floor but in production it will show floor.example.com?

Hello everyone, I’m facing an issue which I just can’t get over. Everything is fine on my local, now I’m deploying the app but when I want to run the initial migrations I get this : return self.cursor.execute(sql, params) django.db.utils.ProgrammingError: relation "dashboard_acceptedcurrencies" does not exist LINE 1: ...d", "dashboard_acceptedcurrencies"."updated" FROM "dashboard... ^ Your help is much appreciated! Regards, Dominik

let me know if this helps https://stackoverflow.com/questions/43698979/django-app-deploy-on-aws-elastic-beanstalk-error-relation-django-site-does-no if you deploy on heroku, try to recreate youe full database if there is no data present

I’m not sure since my error is not related to the site model.

Exactly. But floor will carry platform username in production e.g username.example.com/floor

but it is not what I'm looking for it should be like floor.example.com/page

What does floor represent in that url?

well the issue is "relation doesnt exist" so focus on that

it's just example of subdomain

What you will have is: username.example.com/page/floor floor=slug

I think that I got a solution thank you very much

well the issue is "relation doesnt exist" so focus on that

Please advise: I create a new user, everything is fine. But when I go into the admin and enter data, it displays that the data are incorrect. 3 users have already been created Code in models.py (overriding the base user) - https://www.toptal.com/developers/hastebin/iqehipibem.py

Do you enter all the required fields on the admin page? Username and date of birth is required in your code.

On the admin page i have only mail and password fields

Was able to fix my issue. The problem was that I had a form in my forms.py which was depending on DB data and that has caused the error. Although a little strange for me that this causes problems in the migration creation process.
