Park Search Implementation

Architecture

The park search functionality uses a combination of:

• BaseAutocomplete for search suggestions
• django-htmx for async updates
• Django filters for advanced filtering

Components

1. Forms

   • ParkAutocomplete: Handles search suggestions
   • ParkSearchForm: Integrates autocomplete with search form

2. Views

   • ParkSearchView: Class-based view handling search and filters
   • suggest_parks: Legacy endpoint maintained for backward compatibility

3. Templates

   • Simplified search UI using autocomplete widget
   • Integrated loading indicators
   • Filter form for additional search criteria

Implementation Details

Search Form

class ParkSearchForm(forms.Form):
    park = forms.ModelChoiceField(
        queryset=Park.objects.all(),
        required=False,
        widget=AutocompleteWidget(
            ac_class=ParkAutocomplete,
            attrs={
                'class': 'w-full border-gray-300 rounded-lg form-input dark:border-gray-600 dark:bg-gray-700 dark:text-white',
                'placeholder': 'Search parks...'
            }
        )
    )

Autocomplete

class ParkAutocomplete(BaseAutocomplete):
    model = Park
    search_attrs = ['name']
    
    def get_search_results(self, search):
        return (get_base_park_queryset()
                .filter(name__icontains=search)
                .select_related('owner')
                .order_by('name'))

View Integration

class ParkSearchView(TemplateView):
    template_name = "parks/park_list.html"
    
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['search_form'] = ParkSearchForm(self.request.GET)
        # ... filter handling ...
        return context

Features

1. Security

   • Tiered access control:
     • Public basic search
     • Authenticated users get autocomplete
     • Protected endpoints via settings
   • CSRF protection
   • Input validation

2. Real-time Search

   • Debounced input handling
   • Instant results display
   • Loading indicators

3. Accessibility

   • ARIA labels and roles
   • Keyboard navigation support
   • Screen reader compatibility

4. Integration

   • Works with existing filter system
   • Maintains view mode selection
   • Preserves URL state

Performance Considerations

• Prefetch related owner data
• Uses base queryset optimizations
• Debounced search requests
• Proper index usage on name field

Future Improvements

• Consider adding full-text search
• Implement result caching
• Add geographic search capabilities
• Enhance filter integration
