DBWarden

A database migration system for Python/SQLAlchemy projects.

Installation

pip install dbwarden

Configuration

⚠️ Warning

This is an experimental package. Your fuckups are not mine to fix. You have been warned.

Even though this is an experimental package, I added lots of failsafes to protect the connected DB as to avoid issues.

Create warden.toml in your project:

sqlalchemy_url = "sqlite:///./development.db"

Basic Commands

Command	Description
dbwarden init	Initialize migrations directory
dbwarden make-migrations "name"	Generate SQL from SQLAlchemy models
dbwarden migrate	Apply pending migrations
dbwarden migrate --verbose	Apply with detailed logging
dbwarden rollback	Revert the last migration
dbwarden history	Show migration history
dbwarden status	Show current status

SQLAlchemy Models

DBWarden automatically detects models in models/:

# models/user.py
from sqlalchemy import Column, Integer, String
from sqlalchemy.orm import declarative_base

Base = declarative_base()

class User(Base):
    __tablename__ = "users"
    id = Column(Integer, primary_key=True)
    name = Column(String(100))
    email = Column(String(255), unique=True)

Complete Example

# 1. Initialize
dbwarden init

# 2. Create models in models/

# 3. Generate migration from models
dbwarden make-migrations "create users table"

# 4. Apply
