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) ✅

Entity	Field	Storage	Type	Default	Range
Swimlane	height	swimlanes.height	Number	-1	-1 or 50-2000
List	width	lists.width	Number	272	100-1000
Card	sort	cards.sort	Number	varies	unlimited
Card	swimlaneId	cards.swimlaneId	String	required	any valid ID
Card	listId	cards.listId	String	required	any valid ID
Checklist	sort	checklists.sort	Number	varies	unlimited
ChecklistItem	sort	checklistItems.sort	Number	varies	unlimited

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

---

Per-User Storage (User Profile) ✅

Entity	Field	Storage	Scope
User	Collapse Swimlane	profile.collapsedSwimlanes[boardId][swimlaneId]	Per-user
User	Collapse List	profile.collapsedLists[boardId][listId]	Per-user
User	Hide Labels	profile.hideMiniCardLabelText[boardId]	Per-user

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

Integration Notes

Before Next Phase

1. Verify Schema Validation

   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

   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
