Entity Revision Diff
Extends the Diff module to provide visual revision comparison for non-node content entities.
The Problem
Drupal 10.2+ and 11 core includes version history UI for revisionable entities (list revisions, revert, delete). However, core provides only a simple list - it does NOT include:
- Visual diff comparison between any two revisions
- Radio button selection for choosing which revisions to compare
- Side-by-side or unified view of what changed
The Diff module adds this functionality, but only for nodes out of the box.
What This Module Does
Entity Revision Diff bridges this gap by integrating Diff module's comparison functionality with other entity types:
| Entity Type | Requires |
|---|---|
| Group | Group module (optional) |
| Block Content | Drupal core |
| Media | Drupal core |
| Taxonomy Term | Drupal core |
Note: Node entities are handled by the Diff module directly.
Requirements
- Drupal 10.2+ or 11
- Diff module (2.0.0-beta4+)
Optional
- Group - enables revision diff for Group entities
Paths
| Entity Type | Version History | Diff Comparison |
|---|---|---|
| Group | /group/{id}/revisions | /group/{id}/revisions/view/{left}/{right} |
| Block Content | /admin/content/block/{id}/revisions | /admin/content/block/{id}/revisions/view/{left}/{right} |
| Media | /media/{id}/revisions | /media/{id}/revisions/view/{left}/{right} |
| Taxonomy Term | /taxonomy/term/{id}/revisions | /taxonomy/term/{id}/revisions/view/{left}/{right} |
Features
- Radio button selection for comparing two revisions
- Integration with Diff module's comparison layouts (Unified, Split, Visual Inline)
- Translation-aware revision revert forms
- Bundle-specific revision permissions
- Views field for current revision ID
Permissions
Global permissions
- view all {entity_type} revisions
- revert all {entity_type} revisions
- delete all {entity_type} revisions
Bundle-specific permissions
Generated dynamically for each bundle:
- view {bundle} revisions
- revert {bundle} revisions
- delete {bundle} revisions
Migration from entity_diff_ui
This module replaces entity_diff_ui (deprecated for Drupal 11). Key differences:
| Feature | entity_diff_ui | entity_revision_diff |
|---|---|---|
| Drupal 11 support | No | Yes |
| Diff 2.0 API | No | Yes |
| Group support | No | Yes |
| Architecture | Base + submodules | Single unified module |
All URLs and permissions remain backward compatible.
