Thank you for your time and assistance!

1.I think its not using good authenticate, because authenticate is like function which provides authentication to the user by taking username and password and authenticate  is an part of authentication frsmework try to change that names
2.mention custom apps in settings.py file in installed apps
3.try like
from authenticate.models import #modelnames

Ensure models order it was crucial for one by one creation

[Abdul Qoyyuum Haji Abdul Kadir]

Since you made 2 django projects, you should keep them separate as 2 django projects. Don't merge them into one folder. The right way to do this is to package your authentication app and import that into the other project. See this document on making your authentication app as a reusable app:  Advanced tutorial: How to write reusable apps | Django documentation | Django (djangoproject.com)

Once it's installed as a django app into the RepairAnything project, you can then use authentication API into your repairmodule app. And that's how microservices are usually designed.

you cannot import models from another django project.

Hello Sreedhar,

Thank you for your reply and feedback regarding the naming conventions in my Django project.

To clarify, authentication is the name of my Django project, and authenticate is the name of the app within that project. I chose these names to reflect their respective purposes. Are you suggesting that I should change both the project and app names to avoid confusion with the authentication functions in the framework?

I appreciate your suggestions about mentioning custom apps in the settings.py file and adjusting the import statements. I will certainly ensure that the apps are correctly listed in INSTALLED_APPS and will consider your advice on import practices.

Thank you again for your insights!

Hi Shiva,

You can find plenty of examples online like this one diyframework/django-microservice: Designing microservice with Django REST Framework + MongoDB + Docker

The simpler version is to have one core Django project that doesn't have anything. Then create a 2nd Django project with an app (e.g. a Polls app). When the Polls app is done, package it in such a way that it can be installed in another Django project (resource reference here:Advanced tutorial: How to write reusable apps | Django documentation | Django)

Repeat for X number of services/apps that you want to build, package them, then install them into the core Django project.

The more complicated version is to have each service run their own technology stack (doesn't have to be Django). But the end goal is that each service must be able to communicate with each other through a means of API calls, webhook events or even through PubSub.
