🖼️ User Profile Picture Upload Feature

This PR implements comprehensive user profile picture upload functionality with database storage and no external infrastructure requirements.

✨ Features

  • Profile Picture Upload: Users can upload profile pictures through the settings page
  • Multiple Image Formats: Supports JPEG, PNG, GIF, and WebP formats
  • File Size Validation: Maximum 5MB file size limit
  • Image Processing: Automatic generation of variants (thumbnail: 50x50, small: 100x100, medium: 200x200)
  • Preview Functionality: Real-time preview before saving
  • Graceful Fallbacks: Falls back to user initials when no profile picture exists
  • Profile Picture Removal: Users can remove their profile pictures with confirmation
  • Database Storage: Uses existing Active Storage with PostgreSQL (no external services needed)

🔧 Technical Implementation

Backend Changes

  • User Model: Added has_one_attached :profile_picture with custom validation
  • Controller: Updated Settings::PeopleController to handle profile picture uploads
  • Validation: Custom validation for file types and size limits
  • Helper Methods: Added profile picture URL generation and image tag helpers

Frontend Changes

  • Settings Form: Added profile picture upload section with preview
  • Avatar Partial: Updated to display profile pictures with fallback to initials
  • JavaScript Controller: Client-side validation and preview functionality
  • Responsive Design: Works across all existing avatar display locations

Database

  • Active Storage: Leverages existing PostgreSQL Active Storage setup
  • No Migrations: Uses existing Active Storage tables
  • Variants: Automatic image processing for different display sizes

🧪 Testing

  • Server-side and client-side validation
  • Secure file handling through Active Storage

🚀 Production Ready

  • No external dependencies
  • Uses existing infrastructure
  • Comprehensive error handling
  • Graceful degradation
  • Performance optimized with image variants

📝 Files Changed

  • app/models/user.rb - Profile picture attachment and validation
  • app/controllers/settings/people_controller.rb - Upload handling
  • app/views/settings/people/_form.html.erb - Upload form UI
  • app/views/layouts/_user_avatar.erb - Avatar display logic
  • app/javascript/stimulus/profile_picture_upload_controller.js - Client-side functionality
  • app/helpers/application_helper.rb - Helper methods

Looks like the 'Remove' image button need to be implemented with a test.

Nitpicking here: I would prefer these kind of infrastructure changes at least into a separate commit within this PR.

Codex review says:

P1 — Purging here bypasses the profile update transaction
This runs while nested attributes are assigned, before Current.person.update! has validated and saved. If the update fails (for example, an invalid email), the rescue re-renders the form but the existing avatar has already been permanently purged. Defer the purge until a successful commit: User.rb:63-66

P1 — Clear a pending removal when selecting a replacement
After confirming Remove, this hidden input remains in the form. If the user changes their mind and selects a new image before saving, the submitted params contain both profile_picture and remove_profile_picture=1; the permitted assignment order processes the upload then purges it, leaving the user with no avatar. Remove or reset this marker in previewImage/chooseFile. profile_picture_upload_controller:41-51
