🆕 Latest Release: v0.4.0 - Clean Database Schema

What's New in This Release

Database Overhaul ✅

  • ✅ Clean schema design - NO migrations, fresh init creates correct structure
  • ✅ Removed columns: weight, height (never implemented)
  • ✅ Added litter_id column to dogs table with foreign key
  • ✅ Parents table approach - NO sire/dam columns in dogs table
  • ✅ Proper relationships - Sire/dam stored in separate parents table
  • ✅ Database documentation - Comprehensive DATABASE.md file

API Improvements

  • ✅ Fixed parent handling - Properly inserts into parents table
  • ✅ Added logging - See exactly what's happening during dog creation
  • ✅ Error handling - Graceful fallbacks for missing data
  • ✅ Query optimization - Select only existing columns

Server Improvements

  • ✅ Removed migrations - Clean init.js is source of truth
  • ✅ Simplified startup - Just calls initDatabase()
  • ✅ Better logging - Clear console output with checkmarks
  • ✅ No schema detection - Always uses correct structure

Documentation

  • ✅ DATABASE.md - Complete schema reference
  • ✅ Updated README - Current features and setup
  • ✅ Updated ROADMAP - Accurate progress tracking
  • ✅ Troubleshooting guide - Common issues and solutions

Migration Instructions

For fresh installs, the database will initialize correctly automatically.

For existing installations, you need to start fresh:

# Backup your data
cp data/breedr.db data/breedr.db.backup

# Delete old database
rm data/breedr.db

# Pull latest code
git pull origin docs/clean-schema-and-roadmap-update

# Restart application (creates clean database)
docker-compose restart

Note: Parent relationship data cannot be automatically migrated due to schema change from columns to table. You'll need to re-enter parent relationships.
