# ThrillWiki Version Control System
## Overview
The ThrillWiki Version Control System (VCS) provides comprehensive version tracking, branching, and merging capabilities for all content in the system. It builds upon django-simple-history while adding powerful versioning features.
## Features
- Full version history tracking
- Branch-based development
- Version tagging
- Merge operations with conflict resolution
- Real-time collaborative editing
- Automatic change tracking
## Model Integration
### Making Models Version-Controlled
To add version control to any model, inherit from `HistoricalModel`:
```python
from history_tracking.models import HistoricalModel
class YourModel(HistoricalModel):
# Your model fields here
name = models.CharField(max_length=255)
class Meta:
# Your meta options
```
This automatically provides:
- Full version history
- Change tracking
- Branch support
- Merge capabilities
### Example Integration (from parks/models.py)
```python
from history_tracking.models import HistoricalModel
class Park(HistoricalModel):
name = models.CharField(max_length=255)
description = models.TextField()
def save(self, *args, **kwargs):
# Changes will be automatically tracked
super().save(*args, **kwargs)
```
## Usage Guide
### Basic Version Control Operations
1. Creating a Branch
```python
from history_tracking.managers import BranchManager
# Create a new feature branch
branch_manager = BranchManager()
feature_branch = branch_manager.create_branch(
name="feature/new-park-details",
user=request.user
)
```
2. Recording Changes
```python
from history_tracking.signals import ChangesetContextManager
# Making changes in a specific branch
with ChangesetContextManager(branch=feature_branch, user=request.user):
park = Park.objects.get(id=1)
park.description = "Updated description"
park.save() # Change is automatically tracked in the branch
```
3. Merging Changes
```python
# Merge feature branch back to main
success, conflicts = branch_manager.merge_branches(
source=feature_branch,
target=main_branch,
user=request.user
)
if not success:
# Handle merge conflicts
for conflict in conflicts:
# Resolve conflicts through UI or programmatically
pass
```
4. Working with Tags
```python
from history_tracking.models import VersionTag
# Tag a specific version
VersionTag.objects.create(
name="v1.0.0",
branch=main_branch,
content_type=ContentType.objects.get_for_model(park),
object_id=park.id,
created_by=user
)
```
## UI Integration
### HTMX Components
The system provides HTMX-powered components for real-time version control:
1. Version Control Panel
```html
{% include "history_tracking/version_control_panel.html" %}
```
2. Branch Selection
```html
<div hx-get="{% url 'history:branch-list' %}"
hx-trigger="load, branch-updated from:body">
</div>
```
3. Change History
```html
<div hx-get="{% url 'history:history-view' %}?branch={{ branch.name }}"
hx-trigger="load, branch-selected from:body">
</div>
```
## Best Practices
1. Branch Management
- Create feature branches for significant changes
- Use descriptive branch names (e.g., "feature/new-park-system")
- Clean up merged branches
- Regularly sync with main branch
2. Change Tracking
- Make atomic, related changes
- Provide clear change descriptions
- Group related changes in a single changeset
- Review changes before merging
3. Conflict Resolution
- Resolve conflicts promptly
- Communicate with team members about overlapping changes
- Test after resolving conflicts
- Document resolution decisions
4. Performance
- Use changesets for bulk operations
- Index frequently queried fields
- Clean up old branches and tags
- Monitor system performance
## Error Handling
1. Common Issues
```python
try:
branch_manager.merge_branches(source, target)
except ValidationError as e:
# Handle validation errors
except MergeConflict as e:
# Handle merge conflicts
```
2. Conflict Resolution
```python
from history_tracking.utils import resolve_conflicts
resolved = resolve_conflicts(
source_branch=source,
target_branch=target,
resolutions={
'conflict_id': 'resolution_type', # 'source', 'target', or 'manual'
},
manual_resolutions={
'conflict_id': 'manual resolution content'
},
user=request.user
)
```
## System Maintenance
1. Regular Tasks
- Clean up old branches
- Archive old versions
- Verify data integrity
- Monitor system health
2. Monitoring
```python
from history_tracking.utils import get_system_metrics
metrics = get_system_metrics()
# Check branch counts, merge success rates, etc.
```
## Security Considerations
1. Access Control
- All VCS operations require authentication
- Branch operations are logged
- Merge operations require proper permissions
- Changes are tracked with user attribution
2. Data Protection
- Historical data is preserved
- Audit logs are maintained
- Sensitive data is handled securely
- Backups include version history
## Support and Troubleshooting
For issues or questions:
1. Check the logs for detailed error messages
2. Review the conflict resolution documentation
3. Verify branch and change permissions
4. Contact the development team for assistance
## Contributing
When contributing to the VCS:
1. Follow the established branching pattern
2. Document significant changes
3. Add tests for new features
4. Update technical documentation

# Version Control System UI Improvements
## Recent Improvements
### 1. Template Structure Enhancement
- Moved map initialization to dedicated JavaScript file
- Implemented data attribute pattern for passing data to JavaScript
- Improved template organization and maintainability
### 2. JavaScript Organization
- Created separate `map-init.js` for map functionality
- Established pattern for external JavaScript files
- Improved error handling and script loading
### 3. Asset Management
```javascript
// Static Asset Organization
/static/
/js/
version-control.js // Core VCS functionality
map-init.js // Map initialization logic
/css/
version-control.css // VCS styles
```
## Best Practices Established
### 1. Data Passing Pattern
```html
<!-- Using data attributes for JavaScript configuration -->
<div id="map"
data-lat="{{ coordinates.lat }}"
data-lng="{{ coordinates.lng }}"
data-name="{{ name }}">
</div>
```
### 2. JavaScript Separation
```javascript
// Modular JavaScript organization
document.addEventListener('DOMContentLoaded', function() {
// Initialize components
const mapContainer = document.getElementById('map');
if (mapContainer) {
// Component-specific logic
}
});
```
### 3. Template Structure
```html
{% block content %}
<!-- Main content -->
{% endblock %}
{% block extra_js %}
{{ block.super }}
<!-- Component-specific scripts -->
<script src="{% static 'js/component-script.js' %}"></script>
{% endblock %}
```
## Integration Guidelines
### 1. Adding New Components
1. Create dedicated JavaScript file in `/static/js/`
2. Use data attributes for configuration
3. Follow established loading pattern
4. Update base template if needed
### 2. Version Control UI
1. Include version control UI component
2. Add necessary data attributes
3. Ensure proper script loading
4. Follow established patterns
### 3. Static Asset Management
1. Keep JavaScript files modular
2. Use proper static file organization
3. Follow naming conventions
4. Maintain clear dependencies
## Next Steps
1. Apply this pattern to other templates:
- Ride detail template
- Review detail template
- Company detail template
2. Implement consistent error handling:
```javascript
function handleError(error) {
console.error('Component error:', error);
// Handle error appropriately
}
```
3. Add performance monitoring:
```javascript
// Add timing measurements
const startTime = performance.now();
// Component initialization
const endTime = performance.now();
console.debug(`Component initialized in ${endTime - startTime}ms`);
```
4. Documentation updates:
- Add JavaScript patterns to technical guide
- Update template integration guide
- Document asset organization
