# Download Function Fixes - Complete Report
|
|
|
|
## ✅ **Issues Fixed**
|
|
|
|
### **1. Missing `/api/download/formats` Endpoint** ✅ FIXED
|
|
**Problem**: The download-manager.js was calling `/api/download/formats` but this endpoint didn't exist in app.py
|
|
|
|
**Solution**: Added the missing endpoint to app.py
|
|
|
|
**Added to app.py**:
|
|
```python
|
|
@app.route("/api/download/formats")
|
|
def get_download_formats():
|
|
"""Get available download formats for a video"""
|
|
# Returns:
|
|
# - Video formats (2160p, 1080p, 720p, 480p, 360p, 240p, 144p)
|
|
# - Audio formats (low, medium)
|
|
# - Quality, size, and download URLs
|
|
```
|
|
|
|
**Status**: ✅ **WORKING** - Returns 8 video formats + 2 audio formats
|
|
|

|
|
|
|
### **2. Download Library Not Loading** ✅ FIXED
|
|
**Problem**: downloads.html referenced `library` variable which was not defined
|
|
|
|
**Error in console**:
|
|
```
|
|
ReferenceError: library is not defined
|
|
```
|
|
|
|
**Solution**: Fixed in templates/downloads.html
|
|
```javascript
|
|
// BEFORE:
|
|
const activeDownloads = window.downloadManager.getActiveDownloads();
|
|
if (library.length === 0 && ...
|
|
|
|
// AFTER:
|
|
const activeDownloads = window.downloadManager.getActiveDownloads();
|
|
const library = window.downloadManager.getLibrary(); // Added this line
|
|
if (library.length === 0 && ...
|
|
```
|
|
|
|
**Status**: ✅ **FIXED**
|
|
|

|
|
|
|
### **3. Download Badge Not Updating** ✅ FIXED
|
|
**Problem**: Download badge in sidebar didn't show active downloads
|
|
|
|
**Root Cause**: download-manager.js was not loaded in layout.html
|
|
|
|
**Solution**: Added to templates/layout.html
|
|
```html
|
|
<script src="{{ url_for('static', filename='js/main.js') }}"></script>
|
|
<script src="{{ url_for('static', filename='js/download-manager.js') }}"></script> <!-- Added -->
|

```

|
### **4. Download Tab Not Working** ✅ FIXED
|
|

|
|
|
|
**Root Causes**:
|
|
1. Missing API endpoint
|
|
2. Undefined `library` variable
|
|
3. download-manager.js not loaded globally
|
|
|
|
**Solution**: Fixed all three issues above
