I already have an existing website running and want to transfer just the users (usernames, passwords and emails) to another database for a separate Django website as I am rebuilding it.
You can configure both databases in your django configuration file. select the user data from one database and then put the records in the other.

I built a Django project with a few models. Now I created a second server with the same setup. This one is meant to be the deployment server. Databases are separate from the dev-server.
However can you tell me if I can simply copy the databases from the dev server to the deploy or will the Django logic, since I also mean the user models and permissions etc.
The tables which I created myself are no problem to transfer to the new server. However I am wondering If Django gets confused when I also transfer something like the auth_user Model.
Should this work since I also just copied the backend logic as well?
I'm new to Django.
My project database architecture is like
Having 'Auth_DB' contains all the users login details.
Once user logged in, then in need to fetch the details from the other DB. Here i have databases for each user individually, like:
user_0001
user_0002
user_0003
user_0004
user_0005
Can any one please help how can i achieve this.
Thanks in Advance.
Followed Django multiple and dynamic databases
In summary, this is the process:
Add the new database to settings (at runtime)
Create a file to store these settings for reloading when the server is restarted (at runtime)
Run a script which loads the saved settings files (whenever the server is restarted)
In my Django project, I would like two databases but only one model.
For example, an expert database and an exploit database. The router allows me to write in the exploit database or the expert database according to the users groups and permissions.
But how to duplicate the project model (described in model.py) in both bases?
You need to run migrate on each database. Use this switch to specify the database:
--database DATABASE Nominates a database to synchronize. Defaults to the
"default" database.
DATABASE in this case is the settings key that you are using in your settings.py field to configure each database.
I set up a simple django site using django-allauth.
I created some oauth providers in the database.
Everything is fine and working on my laptop now.
I would like to store the created database tables somehow.
Use case: I want to set up a new development environments on a different PC painlessly.
How to store the initial data of django_allauth, so that after checking out the app from git the command manage.py migrate is all I need to have the relevant database tables filled?
Django_allauth already save those data to the database, you will find them in a table *_SocialApp, here is the model code from django_auth source
I need to connect to a Postgresql server in my Django project. But I'm under strict instructions NOT to make any modifications to the database or tables.
If I'm not wrong, simply adding this DB to settings.py and running syncdb would create and add some django specific tables to the database.
How can I get around this issue? If I add another (local) sqlite DB to settings.py under default and my remote postresql server separately; can I be sure of Django not creating any tables in my server? I couldn't find this info in the documentation.
Thanks
Configure two databases in settings.py, and a create database router to route your queries to the appropriate database.
Route all the Django admin / users stuff to your sqlite database (make it the default database, and make sure that is indeed the one your router returns by default), and single out your application queries that need to go to the Postgres database.
Routers also have a method to locate a DB for writes and one for reads, so you can use this as a failsafe: just make sure db_for_write never returns your Postgres database, and you're good to go.
