New Feature - [FEATURE] Batch Operations for TV Series Management

Description

This pull request introduces comprehensive batch operations for TV series disc management in the Automatic Ripping Machine (ARM). The features enable deterministic folder naming, organized media library structures, batch renaming capabilities, and custom identification lookup for misidentified discs.

This feature set addresses multiple issues with TV series disc management:

• Unpredictable folder names due to timestamp-based naming
• Difficulty organizing multi-disc series
• No way to correct misidentified discs in bulk
• Inconsistent naming across seasons/discs of the same series
• Loss of disc label information after identification (season/disc numbers)

Related Issues

This pull request resolves the following issues:

• #1429: 🔧 Keep original disk label somewhere

  • Problem: Original disc labels (e.g., "FUTURAMA_S3_D2") are lost after OMDb identification, making it impossible to identify which disc/season was ripped
  • Solution: Disc label parsing preserves season/disc information in folder names, and label is stored in job database

• #1294: Incorrectly labels Disc when ripping TV series

  • Problem: TV series discs with labels like "STARGATE_ATLANTIS_S1_D2" get renamed to just "Stargate Atlantis (2004-2009)" losing season/disc info
  • Solution: USE_DISC_LABEL_FOR_TV option parses disc labels and creates folders like "Stargate_Atlantis_S1D2"

This pull request potentially resolves the following issues:

• #1194: 🔧 Edit Settings: Allow selection of type

  • Problem: When a title cannot be found, custom titles default to "unknown" type with no way to correct
  • Partial Solution: Custom identification lookup allows bulk updating of video_type (series/movie) for misidentified discs

• #805: 🔧 TV Show jobs tailoring of names and tracks to rip

  • Problem: TV series management requires manual command-line renaming, lacks season/disc fields in job names
  • Partial Solution: Disc label parsing and batch rename operations automate naming with season/disc info; custom lookup fixes misidentified series

Features Implemented

1. Disc Label-Based TV Series Folder Naming

Description

Parse disc labels to create deterministic, human-readable folder names for TV series discs instead of timestamp-based names.

Configuration

USE_DISC_LABEL_FOR_TV: true  # Enable disc label parsing (opt-in, default: false)

Supported Label Formats

The parser recognizes 15+ common disc label formats:

• S1D1, S01D02 - Compact season/disc format
• S1_D1, S01_D02 - Underscore separator
• S1-D1, S01-D02 - Hyphen separator
• S1 D1, S01 D2 - Space separator
• S1E1D1, S01E01D1 - With episode numbers
• Season1Disc1, Season01Disc02 - Word format
• Season 1 Disc 1 - Word format with spaces
• Mixed formats with series names: BB_S1D1, Breaking_Bad_S01_D01

Example Output

Before: /media/Breaking Bad (2008)_1234567890/
After:  /media/Breaking_Bad_S1D1/

Fallback Behavior

• If disc label parsing fails, falls back to standard naming: {Series Title (Year)}
• Fully backward compatible with existing workflows
• No breaking changes to existing rips

2. TV Series Folder Grouping

Description

Organize multi-disc series under a parent series folder for cleaner media library organization.

Configuration

GROUP_TV_DISCS_UNDER_SERIES: true  # Enable parent folder grouping (opt-in, default: false)

Folder Structure

/media/
  ├── Breaking Bad (2008)/           # Parent series folder
  │   ├── Breaking_Bad_S1D1/         # Season 1 Disc 1
  │   ├── Breaking_Bad_S1D2/         # Season 1 Disc 2
  │   ├── Breaking_Bad_S2D1/         # Season 2 Disc 1
  │   └── Breaking_Bad_S2D2/         # Season 2 Disc 2
  └── Game of Thrones (2011)/        # Another series
      ├── Game_of_Thrones_S1D1/
      └── Game_of_Thrones_S1D2/

Benefits

• Organized media server libraries (Plex, Jellyfin, Emby)
• Easy backup/transfer of complete series
• Clear separation between different shows
• Predictable folder hierarchy

3. Batch Rename Operations (New Tab)

Description

A dedicated "Batch" tab with table view for selecting and batch renaming multiple completed TV series discs.

Key Features

Table View Interface

• Responsive table layout with sortable columns:
  • Checkbox (select/deselect)
  • Poster thumbnail (60x90px)
  • Title
  • Year
  • Type (TV Series/Movie badge)
  • Label (disc label)
  • Started (timestamp)

• Sticky toolbar shows selection count and action buttons
• Row selection - Click anywhere on row to select
• Select all checkbox in table header with indeterminate state support
• Filter button - Toggle between "TV Series Only" and "Show All"
• Dark mode compatible

Multi-Step Workflow

Step 1: Selection & Confirmation

• Select multiple completed discs from table
• Non-TV series items trigger warning with explicit Accept/Cancel buttons
• Shows list of non-series items with job IDs and types

Step 2: Rename Options

Naming Style:
  - Underscore: Breaking_Bad_S1D1

  - Space: Breaking Bad S1D1

Options:
  - Zero-pad numbers (S01D01 vs S1D1)
  - Consolidate into series parent folder
  - Include year in parent folder name

Step 3: Series Detection & Confirmation (Conditional)

• Detects multiple series or outliers
• Radio buttons to select primary series
• Disc assignment table with outlier resolution:
  • Skip this disc
  • Force include in selected series
  • Auto (treat as different series)

Step 4: Preview

• Table showing old path → new path for each job
• Status badges:
  • 🟢 Green: Ready to rename
  • 🟡 Yellow: Conflict (will add timestamp)
  • ⚫ Gray: Skipped/Fallback
• Warnings and conflict notifications
• Back to Options or Execute buttons

Step 5: Results

• Success/failure notification
• Count of renamed folders
• List of skipped jobs (if any)
• Rollback button (undo this operation)
• Auto-reload page after 3 seconds

Database Audit Trail

All batch operations are logged to BatchRenameHistory table:

• Batch ID (UUID)
• User email
• Timestamp
• Old/new paths for each job
• Success/failure status
• Rollback support

4. Custom Identification Lookup

Description

Search TMDB/OMDb to find and apply correct metadata to misidentified discs in bulk.

Use Case

Problem: 5 Breaking Bad discs were misidentified as different shows

Solution:

1. Select all 5 misidentified discs
2. Click "Lookup by Custom Name (5)"
3. Search for "Breaking Bad"
4. Select "Breaking Bad (2008) TV Series" from results
5. Review confirmation table
6. Apply → All 5 discs now have correct metadata

4-Step Workflow

Step 1: Search

• Enter search query (e.g., "Breaking Bad", "The Wire")
• Select content type: TV Series or Movie
• Searches configured provider (TMDB or OMDb)
• Shows list of selected discs

Step 2: Select Result

• Grid view of search results with:
  • Poster images
  • Title
  • Year
  • Type badge (TV Series/Movie)
  • IMDb ID
• Click card or "Select This" button

Step 3: Confirm Application

• Shows selected match with poster and details
• Warning about fields that will be updated:
  • Title
  • Year
  • Video Type
  • IMDb ID
  • Poster URL
• Comparison table: Current → New for all selected discs

Step 4: Results

• Success count
• List of updated jobs
• Error list (if any)
• Auto-reload page after 3 seconds

Updated Job Fields

job.title = selected_title
job.title_manual = selected_title
job.year = selected_year
job.video_type = selected_type  # 'series' or 'movie'
job.imdb_id = selected_imdb_id
job.poster_url = selected_poster_url
job.hasnicetitle = True

Benefits

• Fix misidentified discs in bulk (no manual DB editing)
• Ensures all discs of same series have matching IMDb IDs
• Improves batch rename accuracy (series detection relies on IMDb ID)
• Visual confirmation before applying changes

5. Database Migration Fix

Description

Resolved Alembic "Multiple Heads" error that prevented application startup.

Problem

alembic.util.exc.CommandError: Multiple heads are present;
please specify the head revision on which the new revision should be based,
or perform a merge of the multiple heads using the `alembic merge` command.

Solution

Created merge migration to join conflicting branches:

# arm/migrations/versions/merge_a79af75f4b31_c3d4e5f6g7h8.py
revision = 'm_merge_a79af75f_c3d4e5f'
down_revision = ('a79af75f4b31', 'c3d4e5f6g7h8')

def upgrade():
    pass  # No-op merge

def downgrade():
    pass  # No-op merge

Code Documentation

• Comprehensive docstrings in all new Python modules
• Function-level documentation with parameter descriptions
• Return type documentation
• Example usage in docstrings
• Inline comments for complex logic
• JSDoc-style comments in JavaScript

Security Considerations

CSRF Protection

• Added CSRF meta tag to batch rename view template
• Configured jQuery AJAX to automatically include CSRF token in headers
• All POST requests include X-CSRFToken header
• Flask-WTF validates CSRF tokens on all state-changing operations

Input Validation

• Job IDs validated against database before operations
• File paths sanitized to prevent directory traversal
• Metadata from external APIs (TMDB/OMDb) sanitized before database insert
• User input (search queries, folder names) validated and escaped

Authorization

• All routes protected with @login_required decorator
• User email captured in audit trail for accountability
• Rollback operations restricted to authenticated users

Audit Trail

• All batch operations logged to BatchRenameHistory table
• Captures: user, timestamp, old/new paths, success/failure
• Enables forensic analysis and compliance
• Rollback capability with full history

Performance Considerations

Database Operations

• Batch operations use transactions for atomicity
• Rollback supported via saved old_path values
• Indexed foreign keys for efficient joins
• Per-job config snapshots avoid repeated config file reads

Frontend Optimization

• Table view more efficient than card grid (simpler DOM)
• Lazy loading not needed (completed discs are finite)
• AJAX calls cached during preview/execute cycle
• Toast notifications auto-dismiss (prevent DOM bloat)

File System Operations

• Folder renames use atomic shutil.move()
• Conflict resolution adds timestamps (no data loss)
• Parent directory creation uses os.makedirs(exist_ok=True)
• Proper error handling for file system errors

Breaking Changes

None. All features are opt-in with backward-compatible defaults.

Opt-In Configuration

USE_DISC_LABEL_FOR_TV: false          # Default: disabled
GROUP_TV_DISCS_UNDER_SERIES: false    # Default: disabled

Backward Compatibility

• Existing rips unaffected (standard naming continues to work)
• Database schema migrations are additive (no columns dropped)
• API endpoints are new (no existing endpoints modified)
• Configuration keys are optional (missing keys use defaults)
• Fallback logic ensures robustness (parsing failure → standard naming)

Future Enhancements

Potential Improvements

1. Column Sorting - Click table headers to sort by title, date, type
2. Pagination - For libraries with 100+ completed discs
3. Bulk Actions Dropdown - Delete, reidentify, export, etc.
4. Custom Naming Templates - User-defined folder name patterns
5. Batch Delete - Remove multiple jobs at once
6. Export Selection - Export selected jobs to CSV/JSON
7. Keyboard Navigation - Arrow keys, space to select
8. Saved Filters - Remember TV Series filter preference
9. Batch Identification - Re-identify multiple discs against TMDB/OMDb
10. Series Merge - Merge discs from different rips into single series

Migration Guide for Users

Enabling Disc Label Feature

1. Edit /etc/arm/config/arm.yaml:

USE_DISC_LABEL_FOR_TV: true

2. Ensure your disc labels contain season/disc identifiers:

   • Good: BB_S1D1, Breaking_Bad_S01D01, Season1Disc1
   • Bad: Breaking_Bad_2008, Disc_1 (no season)

3. Rip new discs → folders automatically named Breaking_Bad_S1D1

Enabling Folder Grouping

1. Edit /etc/arm/config/arm.yaml:

USE_DISC_LABEL_FOR_TV: true
GROUP_TV_DISCS_UNDER_SERIES: true

2. Rip new discs → organized under parent folder:

/media/Breaking Bad (2008)/
  ├── Breaking_Bad_S1D1/
  ├── Breaking_Bad_S1D2/
  └── Breaking_Bad_S2D1/

Using Batch Rename

1. Navigate to Batch tab
2. Select completed discs (checkboxes or row clicks)
3. Click Batch Rename Selected (X)
4. Choose options → Preview → Execute
5. (Optional) Rollback if needed

Using Custom Lookup

1. Navigate to Batch tab
2. Select misidentified discs
3. Click Lookup by Custom Name (X)
4. Search for correct title → Select match → Confirm → Apply
5. All selected discs updated with correct metadata
