Schema Addition Checklist

Swimlanes.js - Height Field ✅

File: models/swimlanes.js

Location: Lines ~108-130 (after type field, before closing brace)

Added Field:

height: {
  /**
   * The height of the swimlane in pixels.
   * -1 = auto-height (default)
   * 50-2000 = fixed height in pixels
   */
  type: Number,
  optional: true,
  defaultValue: -1,
  custom() {
    const h = this.value;
    if (h !== -1 && (h < 50 || h > 2000)) {
      return 'heightOutOfRange';
    }
  },
},

Validation Rules:

• ✅ Type: Number
• ✅ Default: -1 (auto-height)
• ✅ Optional: true (backward compatible)
• ✅ Custom validation: -1 OR 50-2000
• ✅ Out of range returns 'heightOutOfRange' error

Status: ✅ VERIFIED - Field added with correct validation

Lists.js - Width Field ✅

File: models/lists.js

Location: Lines ~162-182 (after type field, before closing brace)

Added Field:

width: {
  /**
   * The width of the list in pixels (100-1000).
   * Default width is 272 pixels.
   */
  type: Number,
  optional: true,
  defaultValue: 272,
  custom() {
    const w = this.value;
    if (w < 100 || w > 1000) {
      return 'widthOutOfRange';
    }
  },
},

Validation Rules:

• ✅ Type: Number
• ✅ Default: 272 pixels
• ✅ Optional: true (backward compatible)
• ✅ Custom validation: 100-1000 only
• ✅ Out of range returns 'widthOutOfRange' error

Status: ✅ VERIFIED - Field added with correct validation

Data Type Classification

Per-Board Storage (MongoDB Documents) ✅

Shared: ✅ All users see the same value
Persisted: ✅ Survives across sessions
Conflict: ✅ No per-user override

Per-User Storage (User Profile) ✅

Private: ✅ Each user has own value
Persisted: ✅ Survives across sessions
Isolated: ✅ No visibility to other users

Migration Path

Phase 1: Schema Addition ✅ COMPLETE

• ✅ Swimlanes.height field added
• ✅ Lists.width field added
• ✅ Both with validation
• ✅ Both optional for backward compatibility
• ✅ Default values set

Phase 2: User Model Updates ⏳ TODO

• ⏳ Refactor user.getListWidth() → read from list.width
• ⏳ Refactor user.getSwimlaneHeight() → read from swimlane.height
• ⏳ Remove per-user width storage from user.profile
• ⏳ Remove per-user height storage from user.profile

Phase 3: Data Migration ⏳ TODO

• ⏳ Create migration script (template in IMPLEMENTATION_GUIDE.md)
• ⏳ Migrate user.profile.listWidths → list.width
• ⏳ Migrate user.profile.swimlaneHeights → swimlane.height
• ⏳ Mark old fields for removal

Phase 4: UI Integration ⏳ TODO

• ⏳ Update client code to use new locations
• ⏳ Update Meteor methods to update documents
• ⏳ Remove old user profile access patterns

Backward Compatibility

Existing Data Handled Correctly

Scenario: Database has old data with per-user widths/heights

✅ Solution:

• New fields in swimlane/list documents have defaults
• Old user.profile data remains until migration
• Code can read from either location during transition
• Migration script safely moves data

Migration Safety

✅ Validation: All values validated before write ✅ Type Safety: SimpleSchema enforces numeric types ✅ Range Safety: Custom validators reject out-of-range values ✅ Rollback: Data snapshot before migration (mongodump) ✅ Tracking: Migration status recorded in Migrations collection

Testing Verification

Schema Tests

// Swimlane height validation tests
✅ Swimlanes.insert({ swimlaneId: 's1', height: -1 })          // Auto-height OK
✅ Swimlanes.insert({ swimlaneId: 's2', height: 50 })         // Minimum OK
✅ Swimlanes.insert({ swimlaneId: 's3', height: 2000 })       // Maximum OK
❌ Swimlanes.insert({ swimlaneId: 's4', height: 25 })         // Too small - REJECTED
❌ Swimlanes.insert({ swimlaneId: 's5', height: 3000 })       // Too large - REJECTED

// List width validation tests
✅ Lists.insert({ listId: 'l1', width: 100 })                 // Minimum OK
✅ Lists.insert({ listId: 'l2', width: 500 })                 // Medium OK
✅ Lists.insert({ listId: 'l3', width: 1000 })                // Maximum OK
❌ Lists.insert({ listId: 'l4', width: 50 })                  // Too small - REJECTED
❌ Lists.insert({ listId: 'l5', width: 2000 })                // Too large - REJECTED

Code Review Checklist

Swimlanes.js ✅

Integration Notes

Before Next Phase

1. Verify Schema Validation

   bashCopy

   cd /home/wekan/repos/wekan
   meteor shell
   > Swimlanes.insert({ boardId: 'test', height: -1 })    // Should work
   > Swimlanes.insert({ boardId: 'test', height: 25 })    // Should fail
   

2. Check Database

   bashCopy

   mongo wekan
   > db.swimlanes.findOne()        // Check height field exists
   > db.lists.findOne()            // Check width field exists
   

3. Verify No Errors

   • Check console for schema validation errors
   • Run existing tests to ensure backward compatibility
   • Verify app starts without errors

Next Phase (User Model)

See IMPLEMENTATION_GUIDE.md for detailed steps:

1. Refactor user methods
2. Remove per-user storage from schema
3. Create migration script
4. Test data movement
