## Test Your Changes
|
|
|
|
### 1. Quick Syntax Check
|
|
|
|
```bash
|
|
# Backend
|
|
cd backend
|
|
python -m py_compile server.py
|
|
python -c "import server"
|
|
|
|
# Frontend
|
|
cd frontend
|
|
node -c src/hooks/useAdminAPI.js
|
|
node -c src/hooks/useDialogState.js
|
|
```
|
|
|
|
### 2. Run Full Test Suite
|
|
|
|
```bash
|
|
# Make sure backend is running on port 8181
|
|
./test_refactoring.sh
|
|
```
|
|
|
|
### 3. Manual Testing
|
|
|
|
1. Login as admin (<admin@techzone.com> / admin123)
|
|
2. Navigate to Admin Dashboard
|
|
3. Test each tab (Products, Services, Orders, etc.)
|
|
4. Verify CRUD operations work
|
|
5. Check that errors show appropriate messages
|
|
|
|
## What Was NOT Changed
|
|
|
|
✅ API endpoints and routes
|
|
✅ Request/response formats
|
|
✅ Database schema
|
|
✅ Authentication logic
|
|
✅ Business rules
|
|
✅ Frontend UI appearance
|
|
✅ User experience
|
|
|
|
## Rollback Instructions
|
|
|
|
If you need to undo changes:
|
|
|
|
```bash
|
|
# Option 1: Git rollback (if committed)
|
|
git log --oneline # Find commit before refactoring
|
|
git revert <commit-hash>
|
|
|
|
# Option 2: Manual rollback
|
|
# Just restore the previous version of:
|
|
# - backend/server.py
|
|
# Remove the new hook files if desired
|
|
```
|
|
|
|
## Next Steps
|
|
|
|
### Immediate
|
|
|
|
1. ✅ Run test suite to verify everything works
|
|
2. ✅ Review documentation
|
|
3. ✅ Test in your development environment
|
|
|
|
### Optional (Future)
|
|
|
|
1. **Split AdminDashboard.js** - Break into smaller components
|
|
2. **Add React Query** - Better data management
|
|
3. **Implement caching** - Redis or similar
|
|
4. **Add unit tests** - For new helper functions
|
|
5. **Create OpenAPI docs** - Auto-generated API documentation
|
|
|
|
## Using the New Code
|
|
|
|
### Backend Example
|
|
|
|
```python
|
|
# OLD WAY
|
|
result = await db.execute(select(Product).where(Product.id == id))
|
|
product = result.scalar_one_or_none()
|
|
if not product:
|
|
raise HTTPException(status_code=404, detail="Not found")
|
|
|
|
# NEW WAY
|
|
product = await _get_or_404(db, Product, id)
|
|
```
|
|
|
|
### Frontend Example
|
|
|
|
```javascript
|
|
// OLD WAY
|
|
const response = await axios.get(API + '/admin/products', {
|
|
headers: { Authorization: `Bearer ${token}` }
|
|
});
|
|
|
|
// NEW WAY
|
|
const { apiGet } = useAdminAPI(token);
|
|
const products = await apiGet('/admin/products', 'Failed to load');
|
|
```
