+# Django HTMX Autocomplete Fix - 2025-06-25
+
+## Problem Summary
+
+The RideAutocomplete implementation was failing with `AttributeError: type object 'RideAutocomplete' has no attribute 'as_view'` when trying to start the Django development server.
+
+## Root Cause Analysis
+
+1. **Missing Package**: The `django-htmx-autocomplete` package was not installed
+2. **Incorrect URL Pattern**: The autocomplete URLs were not properly configured according to the library's requirements
+3. **Wrong Base Class**: RideAutocomplete was inheriting from a custom BaseAutocomplete instead of the library's ModelAutocomplete
+4. **Missing Registration**: The autocomplete class was not registered with the @autocomplete.register decorator
+
+## Solutions Implemented
+
+### 1. Package Installation
+```bash
+uv add django-htmx-autocomplete
+```
+
+### 2. URL Configuration Fix
+**File**: `thrillwiki/urls.py`
+- Added autocomplete URLs at project level: `path("ac/", autocomplete_urls)`
+- Imported: `from autocomplete import urls as autocomplete_urls`
+
+### 3. RideAutocomplete Class Fix
+**File**: `search/mixins.py`
+- Changed inheritance from `BaseAutocomplete` to `autocomplete.ModelAutocomplete`
+- Added `@autocomplete.register` decorator
+- Updated `get_search_results()` method signature to include `context` parameter
+- Added `max_results = 10` class attribute
+- Removed manual slicing from queryset (handled by max_results)
+
+### 4. Search URLs Fix
+**File**: `search/urls.py`
+- Removed the problematic autocomplete URL (now handled by main autocomplete package)
+- Fixed import for RideSearchView: `from rides.views import RideSearchView`
+
+## Key Technical Details
+
+### Django HTMX Autocomplete Pattern
+The library requires:
+1. Installation and addition to INSTALLED_APPS (already done)
+2. URL inclusion at project level: `path("ac/", autocomplete_urls)`
+3. Autocomplete classes must inherit from `autocomplete.ModelAutocomplete`
+4. Classes must be decorated with `@autocomplete.register`
+5. Method signature: `get_search_results(self, search, context)`
+
+### Working Implementation
+```python
+@autocomplete.register
+class RideAutocomplete(autocomplete.ModelAutocomplete):
+    model = Ride
+    search_attrs = ['name']
+    max_results = 10
+    
+    def get_search_results(self, search, context):
+        return (Ride.objects
+                .filter(name__icontains=search)
+                .select_related('park')
+                .order_by('name'))
+    
+    def format_result(self, ride):
+        return {
+            'key': str(ride.pk),
+            'label': ride.name,
+            'extra': f"at {ride.park.name}"
+        }
+```
+
+## Status
+
+✅ **RESOLVED**: The RideAutocomplete.as_view() error has been fixed
+✅ **READY**: Server should now start without autocomplete-related errors
+⏳ **NEXT**: Manual HTMX integration testing can proceed
+
+## Dependencies Added
+
+- `django-htmx-autocomplete` - Provides HTMX-powered autocomplete functionality
+
+## Files Modified
+
+1. `thrillwiki/urls.py` - Added autocomplete URL configuration
+2. `search/mixins.py` - Fixed RideAutocomplete class implementation
+3. `search/urls.py` - Removed conflicting URL and fixed imports
+4. `memory-bank/activeContext.md` - Updated task status
+
+## Testing Notes
+
+The unit tests (7/7 passing) validate the core functionality. Manual browser testing is now unblocked and should be performed to verify HTMX integration works correctly.
