yesterday faced an interview where they asked how you configure different db in django and here I am learnt how, now gonna crack the next. Thanks sir... also I am facing below issue ... ''ConnectionDoesNotExist at /admin/blue/blue/''

[@veryacademy]

Hi Rahul, well the very best of luck to you, I am sure you will get that job soon enough. Regarding the error, it is one of those it could be a few things, an incorrect name/typo or migrations out of sync or database config issues.

Hi, a very cool lesson!1 Thank you! Can you tell me, please, the django_migrations file is created in all databases, and it is the same, is it possible to avoid this behavior?7 For example, I have an additional step to change the table, but I don't have access to create a new table, what should I do?

[@veryacademy]

Migrate first and change the migration file before makemigrations

[@narmindm]

Thanks!! I will try to do this

[@gabycarrizal9395]

maybe a dumb question, is mandatory to create multiple applications in order to use multiple connections? or is more like a good practice? sorry I'm new

[@veryacademy]

Never a dumb question. There is no mandatory. If I think I understand, make as many apps as you need. Ideally at least to start with stick with 1 database

[@jairajsahgal7101]

Is there a way to manually select models for saving into different databases?

[@veryacademy]

Hey, models in django refers to tables. Are you asking me how to define which model should be saved in which database?

[@jairajsahgal7101]

@@veryacademy Yes, sorry for poor english. I tried routers method but it would create all the tables inside my default database.

[@jorisjansen2892]

Great tutorial! How would you create relations between models in different databases? Or would you store a reference on a model such as a user_id field, which the user would send with the JWT token, to look for user-specific objects? Cheers

[@ganeshniranjan895]

I am looking for the same ... have you found any solution regarding this

[@jorisjansen2892]

@@ganeshniranjan895 You should store a reference. It's impossible to have relations between different databases. So storing a user_id or user_uuid would be preferred. Good luck!

When creating a custom user model, we must do user.save(using=self._db). Would we do user.save(using=self.users_db) if our custom database's name is users like the case in this video?

Don't need self just the _db

Great question. docs.djangoproject.com/en/3.2/topics/testing/tools/#multi-database-support look for Multi-database support

[@3DGFan9000]

not sure whats going on with mine. I have an AuthRouter, and one called DeliveryRouter. When i migrate database=deliveries_db it brings in all of the auth tables as well, and the other way when i migrate users_db. If I do standard migrate it puts tables from my delivery app on the default database. Looks identical to what you demoed.

[@jaguarnet]

this is unique awesome content, such option drive everyone to think to use django for microservices, if we can split the project in multiple DBs, can we do the same and deploy the Application to multiple servers? if yes this will accomplish the theory of microservice , can we ?

[@veryacademy]

Hi Fahd, yes Django as the framework within microservices setup/architecture - we can do that. As per normal with any suggestion like this we would find 100 people for and and 100 people against doing so. Some would say this would be counter productive, unnecessarily or complicated. There would be some who would suggest with Django sticking with monolithic and deploy to multiple instances with for example a load balancer and hardware tuning. Who needs to learn microservices when we have serverless 😁👍

thanks sir , is it possible to make relations between tables from different databases ? imagine having two dbs : shop_db and auth_db , I created an app called accounts and defined my custom User that inherits from AbstractUser then I migrated it into auth_db , then I created an app called orders and defined an Order model in it , it has a ForeinKey relation to my custom User model , then I migrated Order into shop_db , but when I try to assign a user to an order in admin I get this error : no such table: main.accounts_user

[@veryacademy]

lol Thank you

[@kevinzettel]

the biggest Issue is the admin isn't hooked up to the two remote databases and using the remote databases table it's using it's local table. as such I think this is pointless which you just did and I'm pretty sure after researching for hours that Django can't support the admin table with multiple databases. either don't use the admin table or don't use multiple databases.

[@veryacademy]

Can I just confirm. You would like to see 2 databases used on one admin site. Is that correct.

[@kevinzettel]

​@@veryacademy No I found out that you just have to use the "default". one admin DB and one app db and the admin db must be use the default database. something that took me forever to figure out was the admin.model to connect them. figured it out like 3 hours ago and it's actually really nice with optional admin configurations.
