#+TITLE: Session Notes - Page Flow Feature Implementation
#+DATE: 2025-10-12
#+AUTHOR: Glenn
* Session Objective
Implement role-based page flow for Asteroid Radio application where:
- Admin users are redirected to ~/asteroid/admin~ upon login
- Regular users (listener, dj) are redirected to ~/asteroid/profile~ upon login
- User registration redirects to ~/asteroid/profile~ page
- Navigation links display conditionally based on authentication status and user role
* What Was Accomplished
** Core Feature: Role-Based Page Flow ✅
- Implemented login redirect logic based on user role
- Admin users → ~/asteroid/admin~ dashboard
- Regular users → ~/asteroid/profile~ page
- Registration flow → ~/asteroid/profile~ for new users
- Session persistence across page navigation
** User Management API Endpoints ✅
Converted user management endpoints to use Radiance's ~define-api~ standard:
- ~/api/asteroid/users~ - Get all users (admin only)
- ~/api/asteroid/user-stats~ - Get user statistics (admin only)
- ~/api/asteroid/users/create~ - Create new user (admin only)
** Profile Page API Endpoints ✅
Added new API endpoints for user profile functionality:
- ~/api/asteroid/user/profile~ - Get current user profile information
- ~/api/asteroid/user/listening-stats~ - Get user listening statistics (placeholder)
- ~/api/asteroid/user/recent-tracks~ - Get recently played tracks (placeholder)
- ~/api/asteroid/user/top-artists~ - Get top artists (placeholder)
** Authentication & Authorization Improvements ✅
- Fixed ~require-role~ function to properly handle API requests
- Added proper JSON error responses for authorization failures
- Improved password verification with debug logging
- Added ~reset-user-password~ function for admin use
** JavaScript API Response Handling ✅
Fixed all JavaScript files to properly handle Radiance's ~api-output~ wrapper format:
- Response structure: ~{status: 200, message: "Ok.", data: {...}}~
- Updated all fetch calls to extract ~result.data~ before processing
- Added fallback handling: ~const data = result.data || result~
* Files Modified
** Backend (Common Lisp)
*** ~asteroid.lisp~
- Added profile page API endpoints (~user/profile~, ~user/listening-stats~, ~user/recent-tracks~, ~user/top-artists~)
- All endpoints use ~define-api~ and ~api-output~ for proper JSON responses
- Added ~require-authentication~ checks for protected endpoints
*** ~auth-routes.lisp~
- Fixed user management API endpoints to properly use ~api-output~
- Updated ~/api/asteroid/users~ endpoint for proper JSON responses
- Updated ~/api/asteroid/user-stats~ endpoint for proper JSON responses
- Updated ~/api/asteroid/users/create~ endpoint for proper JSON responses
- Added proper error handling with HTTP status codes (400, 404, 500)
*** ~user-management.lisp~
- Modified ~require-role~ function to return ~nil~ for failed API authorization
- Removed problematic ~radiance:api-output~ calls
- Responsibility for JSON error responses moved to calling endpoints
- Added debug logging for authentication flow
** Frontend (JavaScript)
*** ~static/js/users.js~
- Fixed ~loadUserStats()~ to handle ~api-output~ wrapper
- Fixed ~loadUsers()~ to handle ~api-output~ wrapper
- Fixed ~createNewUser()~ to handle ~api-output~ wrapper
- Updated to properly extract ~result.data~ before processing
*** ~static/js/auth-ui.js~
- Fixed ~checkAuthStatus()~ to handle ~api-output~ wrapper
- Session persistence now working correctly across navigation
- Conditional nav links display properly based on auth status
*** ~static/js/profile.js~
- Fixed ~loadProfileData()~ to handle ~api-output~ wrapper
- Fixed ~loadListeningStats()~ to handle ~api-output~ wrapper
- Fixed ~loadRecentTracks()~ to handle ~api-output~ wrapper
- Fixed ~loadTopArtists()~ to handle ~api-output~ wrapper
- Added safe handling for empty arrays (no errors when no data)
- Used optional chaining (~?.~) for safer DOM queries
** Documentation
*** ~TODO.org~
- Marked "Page Flow" section as complete [2/2] ✅
- Updated notes to reflect working implementation
* Technical Details
** API Response Format
All API endpoints now return responses in this format:
#+BEGIN_SRC json
{
"status": 200,
"message": "Ok.",
"data": {
"status": "success",
"users": [...]
}
}
#+END_SRC
JavaScript must extract the ~data~ property before processing.
** Authentication Flow
1. User submits login form
2. ~authenticate-user~ validates credentials
3. Session field "user-id" is set
4. User role is checked
5. Redirect based on role:
- ~:admin~~/asteroid/admin~
- ~:listener~ or ~:dj~~/asteroid/profile~
** Authorization Pattern
#+BEGIN_SRC lisp
(define-api asteroid/endpoint () ()
"API endpoint description"
(require-role :admin) ; or (require-authentication)
(handler-case
(let ((data (get-some-data)))
(api-output `(("status" . "success")
("data" . ,data))))
(error (e)
(api-output `(("status" . "error")
("message" . ,(format nil "Error: ~a" e)))
:status 500))))
#+END_SRC
* Testing Results
** Successful Tests
- ✅ Admin login redirects to ~/asteroid/admin~
- ✅ Regular user login redirects to ~/asteroid/profile~
- ✅ User registration redirects to ~/asteroid/profile~
- ✅ Session persists across page navigation
- ✅ Nav links display correctly based on role (Profile/Admin/Logout vs Login/Register)
- ✅ User statistics display correctly (3 users, 1 admin, 0 DJs)
- ✅ "View All Users" table displays all users
- ✅ "Create New User" functionality working
- ✅ Profile page loads without errors
- ✅ All API endpoints return proper JSON responses
** Test User Created
- Username: ~testuser~
- Email: ~test@asteroid123~
- Role: ~listener~
- Status: Active
* Git Commits
Three clean commits on ~feature/user-page-flow~ branch:
1. ~c6ac876~ - feat: Implement role-based page flow and user management APIs
2. ~0b5bde8~ - fix: Complete UI fixes for page flow feature
3. ~10bd8b4~ - docs: Mark Page Flow feature as complete in TODO
* Known Limitations
** Profile Page Data
- Listening statistics return placeholder data (all zeros)
- Recent tracks return empty array
- Top artists return empty array
- These are ready for future implementation when listening history tracking is added
** Future Enhancements
- Implement actual listening history tracking
- Add user profile editing functionality
- Add user avatar/photo support
- Implement password reset via email
* Notes for Integration
** For Fade (PostgreSQL Migration)
- User management API endpoints are now standardized with ~define-api~
- All endpoints use ~api-output~ for consistent JSON responses
- Session handling is working correctly
- Ready for database migration - just need to update ~find-user-by-id~, ~get-all-users~, etc.
** For easilokkx (UI Work)
- All JavaScript files now properly handle ~api-output~ wrapper format
- Pattern: ~const data = result.data || result;~
- Profile page has placeholder API endpoints ready for real data
- Auth UI system working correctly for conditional display
* Branch Status
- Branch: ~feature/user-page-flow~
- Status: Complete and tested
- Ready for: Pull Request to upstream/main
- Conflicts: None expected (isolated feature work)
