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:

<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:

<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:

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
