Sure, here's the `user.py` file for the `app/api/v1/models/` directory of the `blog_app` FastAPI backend project using SQLAlchemy with SQLite:


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}', is_active={self.is_active}, is_superuser={self.is_superuser})"

Explanation:




4. We define the following columns for the `User` model:
   - `id`: an integer primary key with an index
   - `username`: a string column that is unique and indexed
   - `email`: a string column that is unique and indexed
   - `hashed_password`: a string column to store the hashed password
   - `is_active`: a boolean column to indicate if the user is active or not (default is `True`)
   - `is_superuser`: a boolean column to indicate if the user is a superuser or not (default is `False`)
