I am using Django Rest Framework to create API for this User model. When I try to add the user using this below-mentioned body.

{
    "first_name": "FName",
    "last_name": "LName",
    "role_id": 1,
    "org_id": 1,
    "project_id": [1,2],
    "created_by": 1,
    "modified_by": 1,
    "status": "Active",
    "email": "emailaddress@gmail.com",
    "password": "pass12345"
}

I am getting the output as

{
    "first_name": "FName",
    "last_name": "LName",
    "role_id": 1,
    "org_id": 1,
    "created_by": 1,
    "modified_by": 1,
    "status": "Active",
    "email": "emailaddress@gmail.com",
    "password": "pass12345"
}

project id is not getting added to database, Can Anybody help my with What has gone wrong?

I am using Djoser library for adding user

http://127.0.0.1:8000/auth/users/

This is the endpoint in Djoser for creating the user.

It seems that you are missing project assignment logic in your create_user() method.
