# Pagination Successfully Applied
|
|
|
|
**Date**: 2025-12-28
|
|
**Status**: ✅ Completed
|
|
|
|
## Changes Applied to dashboard.html
|
|
|
|
### 1. Status Filter Dropdown (Line 564-574)
|
|
Replaced the old quality filter dropdown with a new status filter:
|
|
|
|
```html
|
|
<select id="statusFilter" onchange="changeStatusFilter(this.value)">
|
|
<option value="all">All States</option>
|
|
<option value="discovered">Discovered</option>
|
|
<option value="pending">Pending</option>
|
|
<option value="processing">Processing</option>
|
|
<option value="completed">Completed</option>
|
|
<option value="failed">Failed</option>
|
|
<option value="skipped">Skipped</option>
|
|
</select>
|
|
```
|
|
|
|
**Purpose**: Allows users to filter files by their processing state (discovered, pending, etc.)
|
|
|
|
### 2. Pagination Controls Container (Line 690)
|
|
Added pagination controls after the file list table:
|
|
|
|
```html
|
|
<div id="paginationControls"></div>
|
|
```
|
|
|
|
**Purpose**: Container that displays pagination navigation (Previous/Next buttons, page indicator, page jump input)
|
|
|
|
### 3. Pagination JavaScript (Lines 1440-1625)
|
|
Replaced infinite scroll implementation with traditional pagination:
|
|
|
|
**New Variables**:
|
|
- `currentStatusFilter = 'all'` - Tracks selected status filter
|
|
- `currentPage = 1` - Current page number
|
|
- `totalPages = 1` - Total number of pages
|
|
- `filesPerPage = 100` - Files shown per page
|
|
|
|
**New Functions**:
|
|
- `changeStatusFilter(status)` - Changes status filter and reloads page 1
|
|
- `updatePaginationControls()` - Renders pagination UI with Previous/Next buttons
|
|
- `goToPage(page)` - Navigates to specific page
|
|
- `goToPageInput()` - Handles "Enter" key in page jump input
|
|
|
|
**Updated Functions**:
|
|
- `loadFileQuality()` - Now loads specific page using offset calculation
|
|
- `applyFilter()` - Resets to page 1 when changing attribute filters
|
|
|
|
### 4. Removed Infinite Scroll Code
|
|
- Removed scroll event listeners
|
|
- Removed "Load More" button logic
|
|
- Removed `hasMoreFiles` and `isLoadingMore` variables
|
|
|
|
## How It Works
|
|
|
|
### Combined Filtering
|
|
Users can now combine two types of filters:
|
|
|
|
1. **Status Filter** (dropdown at top):
|
|
- Filters by processing state: discovered, pending, processing, completed, failed, skipped
|
|
- Applies to ALL pages
|
|
|
|
2. **Attribute Filter** (buttons):
|
|
- Filters by video attributes: subtitles, audio channels, resolution, codec, file size
|
|
- Applies to ALL pages
|
|
|
|
**Example**: Select "Discovered" status + "4K" attribute = Shows only discovered 4K files
|
|
|
|
### Pagination Navigation
|
|
|
|
1. **Previous/Next Buttons**:
|
|
- Previous disabled on page 1
|
|
- Next always available (loads next page)
|
|
|
|
2. **Page Indicator**:
|
|
- Shows current page number
|
|
- Shows file range (e.g., "Showing 101-200")
|
|
|
|
3. **Go to Page Input**:
|
|
- Type page number and press Enter
|
|
- Jumps directly to that page
|
|
|
|
### Selection Persistence
|
|
- Selected files remain selected when navigating between pages
|
|
- Changing filters clears all selections
|
|
- "Select All" only affects visible files on current page
|
|
|
|
## Testing
|
|
|
|
After deployment, verify:
|
|
|
|
1. **Status Filter**:
|
|
- Select different statuses (discovered, completed, etc.)
|
|
- Verify file list updates correctly
|
|
- Check that pagination resets to page 1
|
|
|
|
2. **Pagination Navigation**:
|
|
- Click Next to go to page 2
|
|
- Click Previous to return to page 1
|
|
- Use "Go to page" input to jump to specific page
|
|
- Verify Previous button is disabled on page 1
|
|
|
|
3. **Combined Filters**:
|
|
- Select status filter + attribute filter
|
|
- Verify both filters apply correctly
|
|
- Check pagination shows correct results
|
|
|
|
4. **Selection**:
|
|
- Select files on page 1
|
|
- Navigate to page 2
|
|
- Return to page 1 - selections should persist
|
|
- Change filter - selections should clear
|
|
|
|
## Backup
|
|
|
|
A backup of the original dashboard.html was created at:
|
|
`templates/dashboard.html.backup`
|
|
|
|
To restore if needed:
|
|
```bash
|
|
cp templates/dashboard.html.backup templates/dashboard.html
|
|
```
|
|
|
|
## Files Involved
|
|
|
|
- **templates/dashboard.html** - Modified with pagination
|
|
- **templates/dashboard.html.backup** - Original backup
|
|
- **pagination-replacement.js** - Source code for pagination
|
|
- **apply-pagination.py** - Automation script (already run)
|
|
- **PAGINATION-INTEGRATION-GUIDE.md** - Manual integration guide
|
|
|
|
## Next Steps
|
|
|
|
1. Restart the Flask application
|
|
2. Test all pagination features
|
|
3. Verify status filter works correctly
|
|
4. Test combined status + attribute filtering
|
|
5. Verify selection persistence across pages
