Django Best Practices 🌟

📁 Organize Django settings with multiple files:

- Create a settings/ directory
- Include separate files for each environment:
- base.py (common settings)
- local.py (local dev settings)
- staging.py (staging version)
- test.py (test settings)
- production.py (live server settings)

Is that true thought or no ?
Please write down your opinions in comment

If you want to use multiple database in django project you can do it, It is just amazing stuff.

First of all you should fill credentials of your second or third database in "DATABASES" key dict which is located in settings.py of django project, They are included ENGINE, NAME, USER, PASSWORD, HOST, PORT and Name of Database which is using by django orm for Queries For example they are may be second_db or third_db or somthing that you want.
So and after you do all things that we said above you can use db you added in your views with using statement to send queries, if you are saving something to db you can do: my_object.save(using="legacy_users")
through thi you can save one data to multiple db with moving like this:

p = Person(name="Fred")
p.save(using="first")  
p.save(using="second")

There is one issue with using Multiple db
Django’s admin doesn’t have any explicit support for multiple databases - more

How to scale a website to support millions of users? We will explain this step-by-step.

The diagram below illustrates the evolution of a simplified eCommerce website. It goes from a monolithic design on one single server, to a service-oriented/microservice architecture.

Suppose we have two services: inventory service (handles product descriptions and inventory management) and user service (handles user information, registration, login, etc.).

Step 1 - With the growth of the user base, one single application server cannot handle the traffic anymore. We put the application server and the database server into two separate servers.

Step 2 - The business continues to grow, and a single application server is no longer enough. So we deploy a cluster of application servers.

Step 3 - Now the incoming requests have to be routed to multiple application servers, how can we ensure each application server gets an even load? The load balancer handles this nicely.

If you are gonna make SearchView for your project you have to search terms in the any of the models in the application and to do this you search objects by term and you had returned all of object types as separately untill now. So now with this method you will have chance to return results of the objects which you have searched as single keyword which is mean {"key": "value"}.
