Issue: Migration doesn't run
Check:
# View server logs
docker-compose logs breedr
# Or if running locally
cat server.log
Manual migration:
# In Docker
docker exec breedr node /app/server/db/migrations.js
# Locally
node server/db/migrations.js
Issue: Still getting "sire column" error
Possible causes:
-
Old frontend code cached in browser
- Fix: Hard refresh (Ctrl+Shift+R or Cmd+Shift+R)
- Fix: Clear browser cache
-
Container not rebuilt
- Fix:
docker-compose down && docker-compose up --build -d
- Fix:
-
Wrong branch
- Fix:
git branchto verify onfeature/enhanced-litters-and-pedigree
- Fix:
Issue: Form shows blank screen
Cause: Frontend build issue
Fix:
cd client
rm -rf dist node_modules
npm install
npm run build
Issue: Database locked error
Cause: Multiple processes accessing database
Fix:
# Stop all instances
docker-compose down
pkill -f "node.*server"
# Restart
docker-compose up -d
📊 Database Schema (Current)
Dogs Table
CREATE TABLE dogs (
id INTEGER PRIMARY KEY AUTOINCREMENT,
name TEXT NOT NULL,
registration_number TEXT,
microchip TEXT,
sex TEXT CHECK(sex IN ('male', 'female')),
birth_date DATE,
breed TEXT,
color TEXT,
weight REAL,
height REAL,
notes TEXT,
litter_id INTEGER, -- ✅ Links to litter
photo_urls TEXT,
is_active INTEGER DEFAULT 1,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
FOREIGN KEY (litter_id) REFERENCES litters(id)
);
-- ❌ NO sire or dam columns!
Parents Table (Relationships)
CREATE TABLE parents (
id INTEGER PRIMARY KEY AUTOINCREMENT,
dog_id INTEGER NOT NULL,
parent_id INTEGER NOT NULL,
parent_type TEXT NOT NULL CHECK(parent_type IN ('sire', 'dam')),
FOREIGN KEY (dog_id) REFERENCES dogs(id) ON DELETE CASCADE,
FOREIGN KEY (parent_id) REFERENCES dogs(id) ON DELETE CASCADE,
UNIQUE(dog_id, parent_type)
);
📈 What Changed
From Old Schema
CREATE TABLE dogs (
...
sire INTEGER, -- ❌ OLD
dam INTEGER, -- ❌ OLD
...
);
To New Schema
CREATE TABLE dogs (
...
litter_id INTEGER, -- ✅ NEW
...
);
CREATE TABLE parents ( -- ✅ NEW
dog_id INTEGER,
parent_id INTEGER,
parent_type TEXT -- 'sire' or 'dam'
);
Why?
- More flexible relationship model
- Easier to query ancestry
- Better data integrity
- Supports future features (multiple parents, etc.)

parentstable
Migration 002: Add litter_id column

Data Preservation
All existing dog data is preserved:

parentstable)
Nothing is lost!
