# CC Soccer D11 - Session Handoff
**Date:** February 1, 2026
**Session:** Roster Builder Group Management Enhancement
**Branch:** `fix/accept_group_inviation_to_move_to_manager_team`

---

## Summary

Implemented comprehensive group management enhancement for the Roster Builder feature. When Admin loads Roster Builder, existing player-created groups are now displayed correctly with all group members consolidated to the manager's team. Added status tracking (green for complete groups, yellow for pending invitations), admin invitation management, and player-facing registration status display.

---

## What Was Completed

### 1. Group Consolidation in Roster Builder

**File:** `web/modules/custom/ccsoccer/src/Service/TeamBalancerService.php`

Added logic to consolidate group members:
- `consolidateGroups()` method - Moves all group members to the manager's team location
- `syncGroupToRoster()` method - Syncs group members to manager's team after invitation acceptance
- Pending invitation tracking per group for status calculation
- Group status: `complete` (green) if no pending invitations, `pending` (yellow) otherwise

---

### 2. Admin Group Invitations Form Enhancements

**File:** `web/modules/custom/ccsoccer/src/Form/GroupInvitationsForm.php`

Major enhancements to handle pending invitations:
- Injected `TeamBalancerService` for roster syncing
- `loadPendingInvitations()` - Loads from `ccsoccer_invitation` table
- Pending invitation rows displayed in members table with registration status
- `acceptInvitation()` - Returns bool for success/failure handling
- `declineOtherInvitations()` - Auto-declines other pending invitations when one is accepted
- Calls `syncGroupToRoster()` after accepting invitations

---

### 3. Block Invitations to Players in Other Groups

**File:** `web/modules/custom/ccsoccer/src/Controller/GroupController.php`

Fixed invite validation to check for ANY existing group membership:

**Before (broken):** Only checked if player was in THIS specific group
```php
$existing_member = loadByProperties([
  'player' => $invitee_uid,
  'season' => $season->id(),
  'group_id' => $group_id,  // Only this group!
]);
```

**After (fixed):** Checks if player is in ANY group for the season
```php
$invitee_reg = loadByProperties([
  'player' => $invitee_uid,
  'season' => $season->id(),
]);
if ($invitee_registration->get('group_id')->value) {
  // Block with appropriate message
}
```

Now shows: "This player is already in another group for this season."

---

### 4. Registration Status Display for Pending Invitations

**Files Modified:**
- `GroupController.php` - Added `$invitee_has_registration` array tracking
- `ccsoccer.module` - Added `invitee_has_registration` to theme variables (ROOT CAUSE FIX)
- `ccsoccer-group-manage.html.twig` - Displays "Pending" vs "Pending (Not Registered)"
- `group-management.css` - Styling for not-registered status indicator

**Root Cause:** The `invitee_has_registration` variable was being passed from the controller but was NOT declared in the theme hook's variables array, so Drupal wasn't passing it to the template.

---

### 5. CSS Styling Updates

**File:** `web/modules/custom/ccsoccer/css/group-management.css`

Added styling for "Not Registered" status:
```css
.status-pending.status-not-registered {
  color: #dc3545;
}
.status-pending.status-not-registered em {
  font-size: 0.9em;
  color: #856404;
  background: #fff3cd;
  padding: 2px 6px;
  border-radius: 3px;
  margin-left: 4px;
}
```

## Bug Fixes

### Bug 1: Registration Status Not Displaying
**Symptom:** Registered players showed as "Pending (Not Registered)" in player-facing group page
**Root Cause:** `invitee_has_registration` not declared in theme hook variables
**Fix:** Added variable declaration in `ccsoccer.module`

### Bug 2: Could Invite Players Already in Other Groups
**Symptom:** Players already in testuser41's group could be invited by testuser16
**Root Cause:** Validation only checked if player was in THIS group, not ANY group
**Fix:** Changed validation to check for any `group_id` on player's registration

---

## Testing Checklist

- [ ] Clear Drupal cache after deployment
- [ ] Test inviting a registered player - should show "Pending" (not "Not Registered")
- [ ] Test inviting an unregistered email - should show "Pending (Not Registered)"
- [ ] Test inviting a player already in another group - should show error message
- [ ] Test admin accepting invitation - should sync player to manager's team
- [ ] Test admin accepting invitation - should auto-decline other pending invitations
- [ ] Verify Roster Builder shows groups consolidated to manager's team

## Architecture Notes

### Group Management Flow

1. **Player creates group:** Registration gets `group_id`, no `invited_by` (they are manager)
2. **Player invites others:** Creates `ccsoccer_invitation` with `status=pending`
3. **Invitee accepts:** Their registration gets `group_id` + `invited_by` set
4. **Admin loads Roster Builder:** Groups consolidated to manager's team location
5. **Admin accepts invitation:** Calls `syncGroupToRoster()` to place on manager's team

### Key Entities

- **Registration:** `group_id`, `invited_by`, `invitation_status`, `team`
- **Invitation:** `inviter`, `invitee_email`, `group_id`, `status`, `season/team`

---

## Known Issues / Future Work

1. **Group status badges in Roster Builder UI** - May need JavaScript updates for visual display
2. **Tournament group handling** - Similar logic exists but less tested
