## Installation

### Prerequisites
- Odoo 17+ or 18+
- Python 3.8+
- Access to both Odoo instances

### Installation Steps
1. Install the base module:
   ```bash
   pip install odoorpc  # For OdooRPC protocol support
   ```

2. Install module in Odoo:
   - Go to Apps → Search "odoo_to_odoo_sync"
   - Click Install

3. Configure sync instances:
   - Go to Settings → Technical → Odoo Sync → Sync Instances
   - Create new instance with connection details

## Configuration

### Setting Up Sync Instances
1. **Create Sync Instance**:
   - URL: Target Odoo instance URL
   - Database: Target database name
   - Username: API user username
   - API Key: Generate from Odoo user preferences
   - Protocol: Choose XML-RPC, JSON-RPC, or OdooRPC

2. **Test Connection**:
   - Use "Test Connection" button to validate settings
   - Check connection status and error messages

### Model Configuration
1. **Create Sync Model**:
   - Select source model (e.g., res.partner, project.task)
   - Configure target model mapping
   - Set sync priority and conflict resolution strategy

2. **Field Mapping**:
   - Add individual field mappings
   - Configure field transformations if needed
   - Set field priorities for conflict resolution

## Usage

### Basic Synchronization
1. **Manual Sync**:
   - Navigate to Sync Models
   - Select model and click "Sync Now"
   - Monitor progress in Sync Queue

2. **Automatic Sync**:
   - Configure cron jobs for automatic synchronization
   - Set sync frequency per model
   - Monitor via dashboard

### Bidirectional Sync Setup
For complete bidirectional sync between Bemade and customer instances:

#### Server Side (Bemade)
1. Install `odoo_to_odoo_bemade` module
2. Use "Assign Project to Client" wizard
3. Generate project keys and API tokens
4. Share credentials with client

#### Client Side (Customer)
1. Install `odoo_to_odoo_bemade_customer` module
2. Use "Receive Project from Bemade" wizard
3. Enter provided credentials and project key
4. Configure automatic synchronization

## API Usage

### Authentication Format (Odoo 18)
```python
# XML-RPC
{'scope': 'rpc', 'key': 'your_api_key'}

# JSON-RPC
headers = {'Content-Type': 'application/json'}
data = {
    "jsonrpc": "2.0",
    "method": "call",
    "params": {
        "service": "common",
        "method": "login",
        "args": [database, username, api_key]
    }
}

# OdooRPC
odoo.login(database, username, api_key)
```

### Programmatic Sync
```python
# Trigger sync via code
sync_instance = env['odoo.sync.instance'].search([('name', '=', 'target_instance')])
sync_instance.sync_model_ids.sync_now()
```

## Troubleshooting

### Common Issues
1. **Connection Failed**: Check URL, database, credentials
2. **Authentication Error**: Verify API key format (Odoo 18 requires `{'scope': 'rpc', 'key': ...}`)
3. **Model Not Found**: Ensure target model exists on remote instance
4. **Field Mapping Error**: Check field names and access rights

### Debug Mode
Enable debug logging:
```python
import logging
logging.getLogger('odoo.sync').setLevel(logging.DEBUG)
```

## Architecture

### Core Components
- **Sync Instance**: Connection configuration and management
- **Sync Model**: Model-level synchronization settings
- **Sync Queue**: Asynchronous processing and state management
- **Sync Log**: Comprehensive logging and error tracking
- **Conflict Resolution**: Multiple strategies for handling data conflicts

### Data Flow
1. **Initiation**: Manual trigger or cron job
2. **Validation**: Connection and permission checks
3. **Processing**: Queue-based asynchronous execution
4. **Resolution**: Conflict detection and resolution
5. **Logging**: Complete audit trail

## Development

### Extending Functionality
- Custom field transformers: Inherit `odoo.sync.model.field`
- Custom conflict resolvers: Inherit `odoo.sync.conflict.resolver`
- Custom protocols: Inherit `odoo.sync.protocol.handler`

### Testing
Run tests via Odoo UI or programmatically:
```bash
./odoo-bin -d your_database -u odoo_to_odoo_sync --test-enable
```

## Support
For issues and feature requests, please refer to the Odoo logs and check the sync logs in the Odoo interface.
