# Original Positions Tracking Feature
|
||||
|
||||
This feature allows users to see the original positions of swimlanes, lists, and cards before the list naming feature was added in commit [719ef87efceacfe91461a8eeca7cf74d11f4cc0a](https://github.com/wekan/wekan/commit/719ef87efceacfe91461a8eeca7cf74d11f4cc0a).
|
||||
|
||||
## Overview
|
||||
|
||||
The original positions tracking system automatically captures and stores the initial positions of all board entities (swimlanes, lists, and cards) when they are created. This allows users to:
|
||||
|
||||
- View the original position of any entity
|
||||
- See if an entity has moved from its original position
|
||||
- Track the original title before any changes
|
||||
- View a complete history of original positions for a board
|
||||
|
||||
## Features
|
||||
|
||||
### 1. Automatic Position Tracking
|
||||
- **Swimlanes**: Tracks original sort position and title
|
||||
- **Lists**: Tracks original sort position, title, and swimlane assignment
|
||||
- **Cards**: Tracks original sort position, title, swimlane, and list assignment
|
||||
|
||||
### 2. Database Schema
|
||||
The system uses a new `PositionHistory` collection with the following structure:
|
||||
```javascript
|
||||
{
|
||||
boardId: String, // Board ID
|
||||
entityType: String, // 'swimlane', 'list', or 'card'
|
||||
entityId: String, // Entity ID
|
||||
originalPosition: Object, // Original position data
|
||||
originalSwimlaneId: String, // Original swimlane (for lists/cards)
|
||||
originalListId: String, // Original list (for cards)
|
||||
originalTitle: String, // Original title
|
||||
createdAt: Date, // When tracked
|
||||
updatedAt: Date // Last updated
|
||||
}
|
||||
```
|
||||
|
||||
### 3. UI Components
|
||||
|
||||
#### Individual Entity Display
|
||||
- Shows original position information for individual swimlanes, lists, or cards
|
||||
- Indicates if the entity has moved from its original position
|
||||
- Displays original title if different from current title
|
||||
|
||||
#### Board-Level View
|
||||
- Complete overview of all original positions on a board
|
||||
- Filter by entity type (swimlanes, lists, cards)
|
||||
- Search and sort functionality
|
||||
- Export capabilities
|
||||
|
||||
## Usage
|
||||
|
||||
### 1. Automatic Tracking
|
||||
Position tracking happens automatically when entities are created. No manual intervention required.
|
||||
|
||||
### 2. Viewing Original Positions
|
||||
|
||||
#### In Templates
|
||||
```html
|
||||
<!-- Show original position for a swimlane -->
|
||||
{{> originalPosition entityId=swimlane._id entityType="swimlane"}}
|
||||
|
||||
<!-- Show original position for a list -->
|
||||
{{> originalPosition entityId=list._id entityType="list"}}
|
||||
|
||||
<!-- Show original position for a card -->
|
||||
{{> originalPosition entityId=card._id entityType="card"}}
|
||||
```
|
||||
|
||||
#### In JavaScript
|
||||
```javascript
|
||||
import { addOriginalPositionToSwimlane, addOriginalPositionToList, addOriginalPositionToCard } from '/client/lib/originalPositionHelpers';
|
||||
|
||||
// Track original position for a swimlane
|
||||
addOriginalPositionToSwimlane(swimlaneId);
|
||||
|
||||
// Track original position for a list
|
||||
addOriginalPositionToList(listId);
|
||||
|
||||
// Track original position for a card
|
||||
addOriginalPositionToCard(cardId);
|
||||
```
|
||||
|
||||
### 3. Server Methods
|
||||
|
||||
#### Track Original Positions
|
||||
```javascript
|
||||
// Track swimlane
|
||||
Meteor.call('positionHistory.trackSwimlane', swimlaneId);
|
||||
|
||||
// Track list
|
||||
Meteor.call('positionHistory.trackList', listId);
|
||||
|
||||
// Track card
|
||||
Meteor.call('positionHistory.trackCard', cardId);
|
||||
```
|
||||
|
||||
#### Get Original Position Data
|
||||
```javascript
|
||||
// Get swimlane original position
|
||||
Meteor.call('positionHistory.getSwimlaneOriginalPosition', swimlaneId);
|
||||
|
||||
// Get list original position
|
||||
Meteor.call('positionHistory.getListOriginalPosition', listId);
|
||||
|
||||
// Get card original position
|
||||
Meteor.call('positionHistory.getCardOriginalPosition', cardId);
|
||||
```
|
||||
|
||||
#### Check if Entity Has Moved
|
||||
```javascript
|
||||
// Check if swimlane has moved
|
||||
Meteor.call('positionHistory.hasSwimlaneMoved', swimlaneId);
|
||||
|
||||
// Check if list has moved
|
||||
Meteor.call('positionHistory.hasListMoved', listId);
|
||||
|
||||
// Check if card has moved
|
||||
Meteor.call('positionHistory.hasCardMoved', cardId);
|
||||
```
|
||||
|
||||
#### Get Board History
|
||||
```javascript
|
||||
// Get all position history for a board
|
||||
Meteor.call('positionHistory.getBoardHistory', boardId);
|
||||
|
||||
// Get position history by entity type
|
||||
Meteor.call('positionHistory.getBoardHistoryByType', boardId, 'swimlane');
|
||||
Meteor.call('positionHistory.getBoardHistoryByType', boardId, 'list');
|
||||
Meteor.call('positionHistory.getBoardHistoryByType', boardId, 'card');
|
||||
```
|
||||
|
||||
## Integration Examples
|
||||
|
||||
### 1. Add to Swimlane Template
|
||||
```html
|
||||
<template name="swimlane">
|
||||
<div class="swimlane">
|
||||
<!-- Existing swimlane content -->
|
||||
|
||||
<!-- Add original position info -->
|
||||
{{> originalPosition entityId=_id entityType="swimlane"}}
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### 2. Add to List Template
|
||||
```html
|
||||
<template name="list">
|
||||
<div class="list">
|
||||
<!-- Existing list content -->
|
||||
|
||||
<!-- Add original position info -->
|
||||
{{> originalPosition entityId=_id entityType="list"}}
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### 3. Add to Card Template
|
||||
```html
|
||||
<template name="card">
|
||||
<div class="card">
|
||||
<!-- Existing card content -->
|
||||
|
||||
<!-- Add original position info -->
|
||||
{{> originalPosition entityId=_id entityType="card"}}
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
### 4. Add Board-Level View
|
||||
```html
|
||||
<template name="board">
|
||||
<div class="board">
|
||||
<!-- Existing board content -->
|
||||
|
||||
<!-- Add original positions view -->
|
||||
{{> originalPositionsView}}
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### 1. Enable/Disable Tracking
|
||||
Position tracking is enabled by default. To disable it, comment out the tracking hooks in the model files:
|
||||
|
||||
```javascript
|
||||
// In models/swimlanes.js, models/lists.js, models/cards.js
|
||||
// Comment out the tracking hooks:
|
||||
/*
|
||||
Meteor.setTimeout(() => {
|
||||
const entity = Collection.findOne(doc._id);
|
||||
if (entity) {
|
||||
entity.trackOriginalPosition();
|
||||
}
|
||||
}, 100);
|
||||
*/
|
||||
```
|
||||
|
||||
### 2. Customize Display
|
||||
Modify the CSS files to customize the appearance:
|
||||
- `client/components/common/originalPosition.css`
|
||||
- `client/components/boards/originalPositionsView.css`
|
||||
|
||||
## Database Migration
|
||||
|
||||
No database migration is required. The system automatically creates the `PositionHistory` collection when first used.
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- Position tracking adds minimal overhead to entity creation
|
||||
- Original position data is only stored once per entity
|
||||
- Database indexes are created for efficient querying
|
||||
- UI components use reactive data for real-time updates
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### 1. Original Position Not Showing
|
||||
- Check if the entity has been created after the feature was implemented
|
||||
- Verify that the position tracking hooks are enabled
|
||||
- Check browser console for any JavaScript errors
|
||||
|
||||
### 2. Performance Issues
|
||||
- Ensure database indexes are created (happens automatically on startup)
|
||||
- Consider limiting the number of entities displayed in the board view
|
||||
- Use the filter functionality to reduce the number of displayed items
|
||||
|
||||
### 3. Data Inconsistencies
|
||||
- Original position data is only captured when entities are created
|
||||
- Existing entities will not have original position data
|
||||
- Use the refresh functionality to re-scan the board
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- Export original position data to CSV/JSON
|
||||
- Bulk operations for managing original positions
|
||||
- Integration with board templates
|
||||
- Advanced filtering and search capabilities
|
||||
- Position change notifications
|
||||
- Historical position timeline view
|
||||
|
||||
## Support
|
||||
|
||||
For issues or questions about the original positions tracking feature, please:
|
||||
1. Check the browser console for errors
|
||||
2. Verify that all required files are present
|
||||
3. Test with a new board to ensure the feature works correctly
