# Phase 4: Visits + Photos (Revised)

**Timeline**: Week 4
**Goal**: Add visits detection and photo integration
**Dependencies**: Phases 1-3 complete
**Status**: ✅ **COMPLETE** (2025-11-20)

> [!SUCCESS]
> **Implementation Complete and Production Ready**
> - All code files created and integrated
> - E2E tests: 10/10 passing ✅
> - All regression tests passing ✅
> - Core functionality verified and working
> - Ready for production deployment

## 🎯 Phase Objectives

Build on Phases 1-3 by adding:
- ✅ Visits layer (suggested + confirmed)
- ✅ Photos layer with thumbnail markers
- ✅ Visits search/filter in settings panel
- ✅ Photo popups with image preview
- ✅ E2E tests passing

**Deploy Decision**: Users can see detected visits and photos on the map.

**Key Changes from Original Plan:**
- **Reusing existing settings panel** instead of separate visits drawer
- **Using photo thumbnails as markers** instead of camera icons
- **Simplified focus** on core visualization features
- **No visit statistics** on map (available in dedicated visits page)

## 4.1 Visits Layer

Display suggested and confirmed visits with different colors.

**File**: `app/javascript/maps_v2/layers/visits_layer.js`

```javascript
import { BaseLayer } from './base_layer'

/**
 * Visits layer showing suggested and confirmed visits
 * Yellow = suggested, Green = confirmed
 */
export class VisitsLayer extends BaseLayer {
  constructor(map, options = {}) {
    super(map, { id: 'visits', ...options })
  }

  getSourceConfig() {
    return {
      type: 'geojson',
      data: this.data || {
        type: 'FeatureCollection',
        features: []
      }
    }
  }

  getLayerConfigs() {
    return [
      // Visit circles
      {
        id: this.id,
        type: 'circle',
        source: this.sourceId,
        paint: {
          'circle-radius': 12,
          'circle-color': [
            'case',
            ['==', ['get', 'status'], 'confirmed'], '#22c55e', // Green for confirmed
            '#eab308' // Yellow for suggested
          ],
          'circle-stroke-width': 2,
          'circle-stroke-color': '#ffffff',
          'circle-opacity': 0.9
        }
      },

      // Visit labels
      {
        id: `${this.id}-labels`,
        type: 'symbol',
        source: this.sourceId,
        layout: {
          'text-field': ['get', 'name'],
          'text-font': ['Open Sans Bold', 'Arial Unicode MS Bold'],
          'text-size': 11,
          'text-offset': [0, 1.5],
          'text-anchor': 'top'
        },
        paint: {
          'text-color': '#111827',
          'text-halo-color': '#ffffff',
          'text-halo-width': 2
        }

    ]
  }

  getLayerIds() {
    return [this.id, `${this.id}-labels`]
  }
}
```

## 4.2 Photos Layer (with Thumbnails)

Display photos using circular thumbnail markers instead of generic camera icons.

**File**: `app/javascript/maps_v2/layers/photos_layer.js`

```javascript

        return
      }

      try {
        await this.loadImageToMap(imageId, thumbnailUrl)
        this.loadedImages.add(imageId)
      } catch (error) {

        if (!this.map.hasImage(imageId)) {
          this.map.addImage(imageId, image)
        }
        resolve()
      })
    })
  }

  getSourceConfig() {
    return {
      type: 'geojson',
      data: this.data || {
        type: 'FeatureCollection',
        features: []
      }
    }
  }

  getLayerConfigs() {
    return [
      // Photo thumbnail background circle
      {
        id: `${this.id}-background`,
        type: 'circle',
        source: this.sourceId,
        paint: {
          'circle-radius': 22,
          'circle-color': '#ffffff',
          'circle-stroke-width': 2,
          'circle-stroke-color': '#3b82f6'
        }

          'icon-ignore-placement': true
        }
      }
    ]
  }

  getLayerIds() {
    return [`${this.id}-background`, this.id]
  }

  /**
   * Clean up loaded images when layer is removed
   */
  remove() {
    super.remove()
    // Note: We don't remove images from map as they might be reused
  }
}
```

## 4.5 Update Settings Panel

Add visits search and layer toggles to existing settings panel.

**File**: `app/views/maps_v2/_settings_panel.html.erb` (add after heatmap toggle)

```erb
<!-- Visits Layer Toggle -->
<div class="setting-group">
  <label class="setting-checkbox">
    <input type="checkbox"
           data-action="change->maps-v2#toggleVisits">
    <span>Show Visits</span>
  </label>
</div>

<!-- Photos Layer Toggle -->
<div class="setting-group">
  <label class="setting-checkbox">
    <input type="checkbox"
           data-action="change->maps-v2#togglePhotos">
    <span>Show Photos</span>
  </label>
</div>

<!-- Visits Search (shown when visits enabled) -->
<div class="setting-group" data-maps-v2-target="visitsSearch" style="display: none;">
  <label for="visits-search">Search Visits</label>
  <input type="text"

    <option value="confirmed">Confirmed Only</option>
    <option value="suggested">Suggested Only</option>
  </select>
</div>
```

## 4.6 Update Map Controller

Add visits and photos layers to the main controller.

**File**: `app/javascript/controllers/maps_v2_controller.js`

```javascript
// Add imports at top

    this.photosLayer = new PhotosLayer(this.map, {
      visible: this.settings.photosEnabled || false
    })
    await this.photosLayer.add(photosGeoJSON)
  } else {
    await this.photosLayer.update(photosGeoJSON)
  }
}

// Add layers when style is ready (in addAllLayers function)
addVisitsLayer()
await addPhotosLayer()

// Add click handlers
this.map.on('click', 'visits', this.handleVisitClick.bind(this))
this.map.on('click', 'photos', this.handlePhotoClick.bind(this))

// Change cursor on hover
this.map.on('mouseenter', 'visits', () => {
  this.map.getCanvas().style.cursor = 'pointer'

  this.map.getCanvas().style.cursor = 'pointer'
})
this.map.on('mouseleave', 'photos', () => {
  this.map.getCanvas().style.cursor = ''
})

  const params = new URLSearchParams({ start_at, end_at })

  const response = await fetch(`${this.baseURL}/visits?${params}`, {
    headers: this.getHeaders()
  })

  if (!response.ok) {
    throw new Error(`Failed to fetch visits: ${response.statusText}`)
  }

  return response.json()
}

/**
 * Fetch photos for date range
 */
async fetchPhotos({ start_at, end_at }) {
  const params = new URLSearchParams({ start_at, end_at })

  const response = await fetch(`${this.baseURL}/photos?${params}`, {

## ✅ Phase 4 Completion Checklist

### Implementation
- [x] Created visits_layer.js
- [x] Created photos_layer.js (with thumbnails)
- [x] Created visit_popup.js
- [x] Created photo_popup.js
- [x] Updated maps_v2_controller.js
- [x] Updated api_client.js
- [x] Updated settings_manager.js
- [x] Updated settings panel view

### Functionality
- [x] Visits render with correct colors (yellow/green)
- [x] Photos display with thumbnail markers
- [x] Visit popups show details
- [x] Photo popups show preview
- [x] Settings panel toggles work
- [x] Visits search works
- [x] Visit status filter works
- [x] Layers persist visibility settings

### Testing
- [x] All Phase 4 E2E tests pass (10/10 passing)
- [x] Phase 1-3 tests still pass (all regression tests passing)
- [x] Manual testing complete
- [x] Map load event fixed (using `load` instead of `style.load`)
- [x] Photos layer error handling prevents blocking points layer

### Implementation Notes
- ✅ Fixed map initialization to use `map.loaded()` and `load` event
- ✅ Added error handling for async photos layer to prevent blocking
- ✅ Removed debug console logs for production
- ✅ All functionality verified working in production

---

## 🚀 Deployment

```bash
git checkout -b maps-v2-phase-4
git add app/javascript/maps_v2/ app/views/maps_v2/ app/javascript/controllers/ e2e/v2/
git commit -m "feat: Maps V2 Phase 4 - Visits and photos with thumbnails"

# Run all tests (regression)
npx playwright test e2e/v2/

# Deploy to staging
git push origin maps-v2-phase-4
```

---

## 🎉 What's Next?

**Phase 5**: Add areas layer and drawing tools for creating/managing geographic areas.

**Future Enhancements**:
- Photo gallery view when clicking photo clusters
- Visit duration heatmap
- Visit frequency indicators
- Photo timeline scrubber

---

## 📊 Final Implementation Summary

### What Was Built
✅ **Complete Visits & Photos Integration**
- Visits layer with color-coded markers (yellow=suggested, green=confirmed)
- Photos layer with dynamic thumbnail loading
- Interactive popups for both visits and photos
- Settings panel integration with search and filtering
- Full persistence of layer visibility preferences

### Test Results
- **Phase 4 Tests**: 10/10 passing (100%)
