Feature Details

1. Filter Drawer - 动态筛选UI (Dynamic Filter UI) ✅

实现位置 (Implementation):

components/renderers/FilterDrawer.tsx (183 lines)
hooks/useQueryBuilder.ts

核心功能 (Core Features):

✅ Modal overlay with QueryBuilder
✅ Dynamic field definitions support
✅ AND/OR logic toggle
✅ Apply/Clear actions
✅ Active filter count badge
✅ Serialized filter output for API

使用示例 (Usage Example):

<FilterDrawer
  fields={fields}              // Field definitions from metadata
  visible={filterVisible}
  onClose={() => setFilterVisible(false)}
  onApply={(filter) => setFilter(filter)}
/>

集成 (Integration): Used in all list views via ListViewRenderer

2. Swipe Actions - 滑动编辑/删除 (Edit/Delete per Row) ✅

实现位置 (Implementation):

components/renderers/SwipeableRow.tsx (120 lines)

核心功能 (Core Features):

✅ Left-to-right swipe gesture
✅ Edit button (blue background, 80px width)
✅ Delete button (red background, 80px width)
✅ Smooth animation with interpolation
✅ Auto-close after action
✅ Uses react-native-gesture-handler

使用示例 (Usage Example):

<SwipeableRow
  onEdit={() => router.push(`/edit/${record.id}`)}
  onDelete={() => handleDelete(record)}
>
  <MyListItem record={record} />
</SwipeableRow>

集成 (Integration): Wraps each row in ListViewRenderer when handlers provided

3. Record Navigation - 上一个/下一个导航 (Previous/Next Navigation) ✅

实现位置 (Implementation):

components/renderers/DetailViewRenderer.tsx
  - RecordNavigator component (lines 153-210)

核心功能 (Core Features):

✅ Previous/Next buttons with ChevronLeft/ChevronRight icons
✅ Disabled states when no previous/next record
✅ Position label (e.g., "3 of 50")
✅ Integrated with sibling record tracking
✅ Smooth router navigation

使用示例 (Usage Example):

<DetailViewRenderer
  record={record}
  fields={fields}
  onPrevious={handlePrevious}
  onNext={handleNext}
  hasPrevious={currentIndex > 0}
  hasNext={currentIndex < totalRecords - 1}
  positionLabel={`${currentIndex + 1} of ${totalRecords}`}
/>

集成 (Integration): Built into detail view, fetches sibling records with useQuery

4. Widget Layout Grid - 响应式仪表板网格 (Responsive Dashboard Grid) ✅

实现位置 (Implementation):

components/renderers/DashboardViewRenderer.tsx (395 lines)

核心功能 (Core Features):

✅ Responsive breakpoint at 600dp
✅ 2-column layout on tablets (≥600dp)
✅ 1-column layout on phones (<600dp)
✅ Widget span support (span: 1 or 2)
✅ 12px gap between cells
✅ Automatic row wrapping
✅ Dynamic width calculation

网格算法 (Grid Algorithm):

const numColumns = screenWidth >= 600 ? 2 : 1;

for (const widget of widgets) {
  const span = Math.min(widget.span ?? 1, numColumns);
  
  if (currentSpan + span > numColumns && currentRow.length > 0) {
    rows.push(currentRow);
    currentRow = [];
    currentSpan = 0;
  }
  currentRow.push(widget);
  currentSpan += span;
}

支持的组件类型 (Widget Types):

metric / kpi - Numeric metrics with trend indicators
card - Simple card display
list / table - Record lists (max 5 items)
chart - Bar charts with inline visualization

集成 (Integration): Used in dashboard screen with responsive layout

5. Live Dashboard Data - 实时仪表板数据 (Live Query Integration) ✅

实现位置 (Implementation):

hooks/useDashboardData.ts (120 lines)
  - useWidgetQuery(widget) hook

核心功能 (Core Features):

✅ Live useQuery() from SDK per widget
✅ Automatic data refresh via TanStack Query
✅ Per-widget loading states
✅ Aggregate functions support
✅ Multiple widget type support

聚合函数 (Aggregations Supported):

count - Total record count
sum - Sum of field values
avg - Average of field values
min - Minimum field value
max - Maximum field value

数据流 (Data Flow):

Widget Config → useWidgetQuery → useQuery (SDK) → TanStack Query → Live Updates
                    ↓
            Aggregate Calculation
                    ↓
            WidgetDataPayload
                    ↓
            DashboardViewRenderer

使用示例 (Usage Example):

function WidgetDataFetcher({ widget, onData }) {
  const data = useWidgetQuery(widget);
  
  useEffect(() => {
    onData(widget.name, data);
  }, [data, widget.name, onData]);
  
  return null;
}

// In dashboard screen:
{dashboard?.widgets.map((w) => (
  <WidgetDataFetcher
    key={w.name}
    widget={w}
    onData={handleWidgetData}
  />
))}

集成 (Integration): Invisible data fetchers collect live data for all widgets
