# 🚀 BREEDR v0.4.0 - Ready to Deploy!
|
||||
|
||||
## ✅ What's Fixed
|
||||
|
||||
### Database Migration System
|
||||
- **Automatic migrations** run on every server startup
|
||||
- Detects and fixes old `sire`/`dam` column schema
|
||||
- Migrates existing data to `parents` table
|
||||
- Adds missing `litter_id` column
|
||||
- Validates schema after migration
|
||||
- **NO MANUAL SQL REQUIRED!**
|
||||
|
||||
### Frontend Form Fix
|
||||
- Updated `DogForm.jsx` to ensure `sire_id` and `dam_id` are sent as `null` instead of empty strings
|
||||
- Improved ID field handling with proper type conversion
|
||||
- Better null value handling throughout the form
|
||||
|
||||
### Features Included
|
||||
- ✅ Interactive pedigree tree with D3 visualization
|
||||
- ✅ Litter management with parent auto-linking
|
||||
- ✅ Dual parent selection mode (litter or manual)
|
||||
- ✅ Enhanced error handling
|
||||
- ✅ Automatic database repairs
|
||||

## 🚀 How to Deploy
|
||||
|
||||
### Step 1: Pull the Branch
|
||||
|
||||
```bash
|
||||
cd /path/to/breedr
|
||||
git fetch origin
|
||||
git checkout feature/enhanced-litters-and-pedigree
|
||||
git pull origin feature/enhanced-litters-and-pedigree
|
||||
```
|
||||
|
||||
### Step 2: Deploy with Docker (Recommended)
|
||||
|
||||
```bash
|
||||
# Stop current containers
|
||||
docker-compose down
|
||||
|
||||
# Rebuild with new code
|
||||
docker-compose build
|
||||
|
||||
# Start containers
|
||||
docker-compose up -d
|
||||
|
||||
# Watch logs to see migration
|
||||
docker-compose logs -f breedr
|
||||
```
|
||||
|
||||
**You should see:**
|
||||
```

|

|
||||
## 🔍 Troubleshooting
|
||||
|
||||
### Issue: Migration doesn't run
|
||||
|
||||
**Check:**
|
||||
```bash
|
||||
# View server logs
|
||||
docker-compose logs breedr
|
||||
|
||||
# Or if running locally
|
||||
cat server.log
|
||||
```
|
||||
|
||||
**Manual migration:**
|
||||
```bash
|
||||
# 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:**
|
||||
1. Old frontend code cached in browser
|
||||
- **Fix:** Hard refresh (Ctrl+Shift+R or Cmd+Shift+R)
|
||||
- **Fix:** Clear browser cache
|
||||
|
||||
2. Container not rebuilt
|
||||
- **Fix:** `docker-compose down && docker-compose up --build -d`
|
||||
|
||||
3. Wrong branch
|
||||
- **Fix:** `git branch` to verify on `feature/enhanced-litters-and-pedigree`
|
||||
|
||||
### Issue: Form shows blank screen
|
||||
|
||||
**Cause:** Frontend build issue
|
||||
|
||||
**Fix:**
|
||||
```bash
|
||||
cd client
|
||||
rm -rf dist node_modules
|
||||
npm install
|
||||
npm run build
|
||||
```
|
||||
|
||||
### Issue: Database locked error
|
||||
|
||||
**Cause:** Multiple processes accessing database
|
||||
|
||||
**Fix:**
|
||||
```bash
|
||||
# Stop all instances
|
||||
docker-compose down
|
||||
pkill -f "node.*server"
|
||||
|
||||
# Restart
|
||||
docker-compose up -d
|
||||
```
|
||||

|
||||
|
||||
## 📊 Database Schema (Current)
|
||||
|
||||
### Dogs Table
|
||||
```sql
|
||||
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)
|
||||
```sql
|
||||
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
|
||||
```sql
|
||||
CREATE TABLE dogs (
|
||||
...
|
||||
sire INTEGER, -- ❌ OLD
|
||||
dam INTEGER, -- ❌ OLD
|
||||
...
|
||||
);
|
||||
```
|
||||
|
||||
### To New Schema
|
||||
```sql
|
||||
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.)

||||
