class_methods do
# Provides access to a dependent RichText model that holds the body and attachments for a single named rich text attribute.
# This dependent attribute is lazily instantiated and will be auto-saved when it's been changed. Example:
#
# class Message < ActiveRecord::Base
# has_rich_text :content
# end
#
# message = Message.create!(content: "<h1>Funny times!</h1>")
# message.content.to_s # => "<h1>Funny times!</h1>"
# message.content.body.to_plain_text # => "Funny times!"
#
# The dependent RichText model will also automatically process attachments links as sent via the Trix-powered editor.
# These attachments are associated with the RichText model using Active Storage.
#
# If you wish to preload the dependent RichText model, you can use the named scope:
#
# Message.all.with_rich_text_content # Avoids N+1 queries when you just want the body, not the attachments.
# Message.all.with_rich_text_content_and_emebds # Avoids N+1 queries when you just want the body and attachments.
