Overview

rails g domternal:migrate_from_action_text

Copies every action_text_rich_texts row into domternal_rich_texts, rewriting the nodes that Domternal has no equivalent for. Writes a normal timestamped migration so it runs through the usual deploy path and stays reversible.

def show_notes
  say <<~NOTES, :green

    Review the generated migration before running it. It:

      * copies bodies verbatim (both use sanitized HTML, so no conversion is needed)
      * turns image attachments into <img> tags on Active Storage redirect URLs, which
        is the same markup the editor's upload handler writes
      * re-attaches the referenced blobs as Domternal::RichText embeds
      * leaves action_text_rich_texts untouched, so you can roll back

    Non-image attachables (ActionText::Attachable models of your own) are dropped unless
    you tell it what to render — see ATTACHABLE_REPLACEMENTS in the migration.
