Here's the `user.py` file for the `app/api/v1/models/` directory in the `blog_app_igblf` FastAPI backend:

from sqlalchemy import Column, Integer, String, Boolean
from app.db import Base

class User(Base):
    __tablename__ = "users"

    id = Column(Integer, primary_key=True, index=True)
    username = Column(String, unique=True, index=True)
    email = Column(String, unique=True, index=True)
    hashed_password = Column(String)
    is_active = Column(Boolean, default=True)
    is_superuser = Column(Boolean, default=False)

    def __repr__(self):
        return f"User(id={self.id}, username='{self.username}', email='{self.email}')"

This file defines a SQLAlchemy model named `User` that inherits from the `Base` class (which should be defined in `app/db.py`). The `User` model has the following columns:

- `is_active`: A boolean indicating whether the user is active or not (default is `True`).
- `is_superuser`: A boolean indicating whether the user is a superuser or not (default is `False`).


Make sure to import the necessary modules (`sqlalchemy` and `app.db`) at the top of the file. Also, ensure that the `Base` class is properly defined in `app/db.py` and that the SQLite database is correctly configured and initialized in your FastAPI application.
