# 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. |
