@mshibuya , How do you use actiontext with rails_admin?

[nezirz]

@mshibuya old question but let me add comment its about rails 7.0.4 and you need just to do:
1 - bin/rails action_text:install

2 - # app/models/message.rb

class Message < ApplicationRecord
  has_rich_text :content
end 

3 - in case that you see broken images you will need this setting
Use mini_magick , just include in config/application.rb

config.active_storage.variant_processor = :mini_magick

Good, could you update the Wiki entry as well?
