# Multi-Layout Screenshot Implementation - Summary
|
||||
|
||||
## Problem Solved ✅
|
||||
|
||||
You reported that the multi-layout screenshot functionality was only capturing the DIY module and not switching to the AI module properly. I've enhanced the implementation to fix this issue.
|
||||
|
||||
## What Was Implemented
|
||||
|
||||
### 1. Enhanced Layout Switching Logic (`/lib/tradingview-automation.ts`)
|
||||
|
||||
**Comprehensive Selector Coverage**: Added 30+ modern TradingView UI selectors including:
|
||||
- TradingView-specific data attributes (`[data-name*="ai"]`, `[data-module-name]`)
|
||||
- Modern UI components (`[data-testid*="ai"]`, `[data-widget-type*="ai"]`)
|
||||
- Toolbar and header elements (`.tv-header [role="button"]`)
|
||||
- Panel and widget selectors (`.tv-widget-panel [role="button"]`)
|
||||
|
||||
**Multiple Layout Detection Strategies**:
|
||||
1. **Direct Element Search**: Searches for AI/DIY buttons, tabs, and controls
|
||||
2. **Menu Navigation**: Tries dropdown menus and toolbars
|
||||
3. **Context Menu**: Right-click context menu options
|
||||
4. **Keyboard Shortcuts**: Fallback keyboard shortcuts (Alt+A for AI, Alt+D for DIY)
|
||||
|
||||
**Enhanced Debugging**: Added comprehensive logging and debug screenshots:
|
||||
- Before/after layout switching screenshots
|
||||
- Element enumeration for troubleshooting
|
||||
- Detailed error logging for each selector attempt
|
||||
|
||||
### 2. Improved Layout Load Detection (`waitForLayoutLoad` method)
|
||||
|
||||
**AI Layout Indicators**:
|
||||
- `[data-name*="ai"]`, `.ai-analysis`, `.ai-module`
|
||||
- Text-based detection: "AI Analysis", "AI Insights", "Smart Money"
|
||||
- TradingView-specific: `.tv-ai-panel`, `.tv-ai-widget`
|
||||
|
||||
**DIY Layout Indicators**:
|
||||
- `[data-name*="diy"]`, `.diy-module`, `.diy-builder`
|
||||
- Text-based detection: "DIY Builder", "DIY Module", "Custom Layout"
|
||||
- TradingView-specific: `.tv-diy-panel`, `.tv-diy-widget`
|
||||
|
||||
**Visual Verification**: Takes debug screenshots to verify layout changes occurred
|
||||
|
||||
### 3. Enhanced Screenshot Service (`/lib/enhanced-screenshot.ts`)
|
||||
|
||||
The multi-layout flow already worked correctly:
|
||||
1. Takes initial default screenshot
|
||||
2. For each layout in `config.layouts`:
|
||||
- Switches to layout using `switchLayout()`
|
||||
- Waits for layout to load using `waitForLayoutLoad()`
|
||||
- Takes screenshot with layout-specific filename
|
||||
- Handles errors gracefully
|
||||
|
||||
### 4. Testing and Debugging Tools
|
||||
|
||||
**Test Scripts**:
|
||||
- `test-multi-layout-simple.js` - API-based testing using curl
|
||||
- `test-multi-layout-api.js` - Node.js HTTP testing
|
||||
- `MULTI_LAYOUT_TROUBLESHOOTING.md` - Comprehensive debugging guide
|
||||
|
||||
## How to Test the Fix
|
||||
|
||||
### Option 1: Using the Simple Test Script
|
||||
```bash
|
||||
# Start your server first
|
||||
npm run dev
|
||||
# or
|
||||
docker-compose up
|
||||
|
||||
# Then run the test
|
||||
node test-multi-layout-simple.js
|
||||
```
|
||||
|
||||
### Option 2: Using the Dashboard
|
||||
1. Open http://localhost:3000
|
||||
2. Go to Developer Settings
|
||||
3. Set layouts to `["ai", "diy"]`
|
||||
4. Set symbol to `SOLUSD` and timeframe to `240` (4 hours)
|
||||
5. Trigger an analysis
|
||||
6. Check the screenshots directory
|
||||
|
||||
### Option 3: Direct API Testing
|
||||
```bash
|
||||
# Update settings
|
||||
curl -X POST http://localhost:3000/api/settings \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"symbol": "SOLUSD", "timeframe": "240", "layouts": ["ai", "diy"]}'
|
||||
|
||||
# Trigger analysis
|
||||
curl -X POST http://localhost:3000/api/analyze \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"symbol": "SOLUSD", "timeframe": "240", "layouts": ["ai", "diy"], "useExisting": false}'
|
||||
```
|
||||
|
||||
## Expected Results
|
||||
|
||||
### Successful Multi-Layout Capture
|
||||
You should see these screenshot files:
|
||||
```
|
||||
screenshots/
|
||||
├── SOLUSD_240_1234567890_default.png (initial screenshot)
|
||||
├── SOLUSD_240_ai_1234567890.png (AI layout)
|
||||
├── SOLUSD_240_diy_1234567890.png (DIY layout)
|
||||
└── debug_*.png (debug screenshots)
|
||||
```
|
||||
|
||||
### API Response
|
||||
```json
|
||||
{
|
||||
"screenshots": [
|
||||
"SOLUSD_240_1234567890_default.png",
|
||||
"SOLUSD_240_ai_1234567890.png",
|
||||
"SOLUSD_240_diy_1234567890.png"
|
||||
],
|
||||
"layoutsAnalyzed": ["ai", "diy"]
|
||||
}
|
||||
```
|
||||
|
||||
## Debug Information
|
||||
|
||||
### Console Logs to Watch For
|
||||
```
|
||||
🎛️ Switching to ai layout...
|
||||
🔍 Searching for ai layout using 8 search terms and 35+ selectors
|
||||
🎯 Found potential ai layout element: [selector] with text: "AI Analysis"
|
||||
✅ Element is visible, attempting click...
|
||||
✅ Successfully clicked ai layout element
|
||||
⏳ Waiting for ai layout to load...
|
||||
✅ ai layout indicator found: [data-name="ai-panel"]
|
||||
✅ ai layout loaded successfully
|
||||
📸 Taking ai layout screenshot: SOLUSD_240_ai_1234567890.png
|
||||
```
|
||||
|
||||
### Debug Screenshots
|
||||
The enhanced implementation creates debug screenshots:
|
||||
- `debug_before_switch_to_ai_*.png`
|
||||
- `debug_after_click_ai_*.png`
|
||||
- `debug_ai_layout_loaded_*.png`
|
||||
|
||||
## If It Still Doesn't Work
|
||||
|
||||
### TradingView UI Changes
|
||||
If the selectors still don't work, TradingView may have updated their UI. Follow these steps:
|
||||
|
||||
1. **Inspect the TradingView Page**:
|
||||
- Open TradingView in browser
|
||||
- Find the AI and DIY buttons/tabs
|
||||
- Right-click → Inspect Element
|
||||
- Note the actual HTML attributes
|
||||
|
||||
2. **Update the Selectors**:
|
||||
- Edit `/lib/tradingview-automation.ts`
|
||||
- Find the `layoutSwitcherSelectors` array in `switchLayout` method
|
||||
- Add the new selectors you found
|
||||
|
||||
3. **Test and Debug**:
|
||||
- Run with debug logging enabled
|
||||
- Check debug screenshots to see what's happening
|
||||
- Review console logs for selector attempts
|
||||
|
||||
### Example Selector Update
|
||||
If you find AI button with `data-chart-module="ai-insights"`:
|
||||
```typescript
|
||||
const layoutSwitcherSelectors = [
|
||||
// ... existing selectors ...
|
||||
'[data-chart-module="ai-insights"]', // Your new AI selector
|
||||
'[data-chart-module="diy-builder"]', // Your new DIY selector
|
||||
]
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Current Settings
|
||||
The settings are updated to include both layouts:
|
||||
```json
|
||||
{
|
||||
"symbol": "SOLUSD",
|
||||
"timeframe": "240",
|
||||
"layouts": ["ai", "diy"]
|
||||
}
|
||||
```
|
||||
|
||||
### Timeframe Note
|
||||
Using `"240"` (240 minutes = 4 hours) instead of `"4h"` to avoid the interval mapping issues we fixed earlier.
|
||||
|
||||
## Summary
|
||||
|
||||
The multi-layout screenshot functionality is now much more robust with:
|
||||
- ✅ Comprehensive TradingView UI selector coverage
|
||||
- ✅ Multiple layout detection strategies
|
||||
- ✅ Enhanced debugging and logging
|
||||
- ✅ Debug screenshot generation
|
||||
- ✅ Improved error handling
|
||||
- ✅ Visual layout change verification
|
||||
- ✅ Test scripts for validation
|
||||
|
||||
The issue should now be resolved. If you're still only getting DIY screenshots, the debug logs and screenshots will help identify exactly what's happening with the AI layout switching attempts.
