## 🎬 Your Next Step
|
||||
|
||||
**You need to choose your MongoDB hosting:**
|
||||
|
||||
### Option A: MongoDB Atlas (Recommended)
|
||||
|
||||
**For cross-device access (PC, mobile, tablet)**
|
||||
|
||||
1. **Sign up:** <https://www.mongodb.com/cloud/atlas/register>
|
||||
2. **Create FREE M0 cluster** (5 minutes setup)
|
||||
3. **Get connection string**
|
||||
4. **Update `backend/.env`:**
|
||||
|
||||
```env
|
||||
MONGODB_URI=mongodb+srv://username:password@cluster.mongodb.net/
|
||||
MONGODB_DATABASE=church_songlyric
|
||||
```
|
||||
|
||||
5. **Test connection:** `.\backend\test_mongodb_connection.ps1`
|
||||
6. **Run migration:** `.\backend\venv\Scripts\python.exe backend\migrate_to_mongodb.py`
|
||||
|
||||
**Detailed guide:** Open `MONGODB_ATLAS_SETUP.md`
|
||||
|
||||
### Option B: Local MongoDB
|
||||
|
||||
**For PC-only access**
|
||||
|
||||
1. **Download:** <https://www.mongodb.com/try/download/community>
|
||||
2. **Install** MongoDB Community Server
|
||||
3. **Verify service running:** `Get-Service MongoDB`
|
||||
4. **Default .env already configured** for localhost
|
||||
5. **Test connection:** `.\backend\test_mongodb_connection.ps1`
|
||||
6. **Run migration:** `.\backend\venv\Scripts\python.exe backend\migrate_to_mongodb.py`
|
||||
|
||||
## 📊 Migration Preview
|
||||
|
||||
**Your data to migrate:**
|
||||
|
||||
- 📀 39 Songs (with lyrics, chords, artist info)
|
||||
- 👤 5 Profiles (user accounts with settings)
|
||||
- 🔗 5 Profile-Song links (custom keys per profile)
|
||||
- 📅 0 Plans (worship setlists)
|
||||
|
||||
**Migration process:**
|
||||
|
||||
1. Connects to both SQLite and MongoDB
|
||||
2. Reads all records from SQLite (non-destructive)
|
||||
3. Creates MongoDB collections with indexes
|
||||
4. Inserts documents into MongoDB
|
||||
5. Verifies record counts match
|
||||
6. Shows detailed report
|
||||
|
||||
**Estimated time:** < 1 minute
|
||||
|
||||
## 🚀 After Migration
|
||||
|
||||
Once migration completes successfully, I'll:
|
||||
|
||||
1. **Update `app.py`** to use MongoDB
|
||||
- Replace all SQLAlchemy queries with PyMongo
|
||||
- Maintain identical API responses
|
||||
- Keep all endpoints functioning the same
|
||||
|
||||
2. **Test thoroughly**
|
||||
- Verify all 16 API endpoints work
|
||||
- Test profile selection and song queries
|
||||
- Ensure frontend displays all data correctly
|
||||
|
||||
3. **Cross-device testing**
|
||||
- Verify PC can access data
|
||||
- Verify mobile can access data
|
||||
- Verify tablet can access data
|
||||
- Test real-time sync across devices
|
||||
|
||||
4. **Clean up obsolete code**
|
||||
- Remove `models.py` (SQLAlchemy)
|
||||
- Backup and remove `app.db` (SQLite)
|
||||
- Remove unused session management code
|
||||
- Update requirements.txt
|
||||
- Clean documentation
|
||||
|
||||
5. **Performance optimization**
|
||||
- Verify query performance
|
||||
- Monitor connection pool usage
|
||||
- Test under load
|
||||
|
||||
## ⚡ Quick Start Commands
|
||||
|
||||
### Test MongoDB Connection
|
||||
|
||||
```powershell
|
||||
cd "E:\Documents\Website Projects\Church_SongLyric\backend"
|
||||
.\test_mongodb_connection.ps1
|
||||
```
|
||||
|
||||
### Run Migration
|
||||
|
||||
```powershell
|
||||
cd "E:\Documents\Website Projects\Church_SongLyric\backend"
|
||||
.\venv\Scripts\python.exe migrate_to_mongodb.py
|
||||
```
|
||||
|
||||
### Check Migration Results
|
||||
|
||||
After migration, verify data in:
|
||||
|
||||
- **MongoDB Atlas:** Dashboard → Clusters → Browse Collections
|
||||
- **Local MongoDB:** MongoDB Compass (download from mongodb.com)
|
||||
|
||||
## 📋 Checklist
|
||||
|
||||
- [ ] Choose MongoDB option (Atlas or Local)
|
||||
- [ ] Complete MongoDB setup
|
||||
- [ ] Update `backend/.env` with connection string
|
||||
- [ ] Test connection (`test_mongodb_connection.ps1`)
|
||||
- [ ] Run migration (`migrate_to_mongodb.py`)
|
||||
- [ ] Verify data in MongoDB
|
||||
- [ ] Notify me - I'll update app.py for MongoDB
|
||||
- [ ] Test all API endpoints
|
||||
- [ ] Test cross-device access
|
||||
- [ ] Clean up old SQLite code
|
||||
|
||||
## ❓ Need Help?
|
||||
|
||||
**Question:** "Which option should I choose?"
|
||||
**Answer:** MongoDB Atlas if you want mobile/tablet access. Local MongoDB if PC-only is acceptable.
|
||||
|
||||
**Question:** "Is my data safe?"
|
||||
**Answer:** Yes! Migration only reads from SQLite, never modifies it. Your original database is untouched.
|
||||
|
||||
**Question:** "What if something goes wrong?"
|
||||
**Answer:** Migration can be run multiple times. If it fails, your original data is still safe in SQLite.
|
||||
|
||||
**Question:** "How long will this take?"
|
||||
**Answer:**
|
||||
|
||||
- MongoDB Atlas setup: 5-10 minutes
|
||||
- Local MongoDB install: 15-20 minutes
|
||||
- Migration itself: < 1 minute
|
||||
- Testing and cleanup: 10-15 minutes
|
||||
|
||||
## 🎯 Current Status
|
||||
|
||||
**STATUS:** ⏸️ **WAITING FOR MONGODB SETUP**
|
||||
|
||||
Once you complete MongoDB setup (Atlas or Local), let me know and I'll:
|
||||
|
||||
1. Help test the connection
|
||||
2. Run the migration with you
|
||||
3. Update the app to use MongoDB
|
||||
4. Test everything works
|
||||
5. Clean up old code
|
||||
|
||||
**You're ready to proceed!** Choose your MongoDB option and follow the setup guide. 🚀
