Rails Action Text Expert
Implement rich text editing in Rails applications using Action Text with the Lexxy editor (Rails 8.1+) or Trix (Rails 6-8.0).
Key Concepts
Action Text stores rich text in a separate action_text_rich_texts table via polymorphic associations — not in your model's table. It handles sanitization, rendering, attachments (via Active Storage), and embedded objects (via Signed GlobalIDs).
Editor History:
- Trix — Original Action Text editor (Rails 6+). Still works, still supported.
- Lexxy — Modern replacement from Basecamp (Rails 8.1+). Better dark mode, CSS custom properties, improved UX. Use Lexxy for new projects.
When To Use This Skill
- Adding rich text fields to a model
- Setting up Action Text in a new or existing Rails app
- Configuring Lexxy or Trix editor appearance
- Rendering rich text content safely
- Handling image/file attachments in rich text
