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.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_embeds # Avoids N+1 queries when you just want the body and attachments.
