Rails 6 comes with ActionText which allows you to edit and display rich text in your applications.
A quick introduction to using ActionText in your Rails apps for editing and displaying rich text plus uploading files
Mentioning Users with an @mention is a super common feature. Trix and ActionText are now part of Rails 6 which means we can very easily add support for tagging users with @mentions and other custom attachments in your applications.
When you at-mention a user, you typically want to send email or other types of notifications to alert that user they were mentioned. In this episode, we'll look into ActionText Content to see how we can extract the user mention attachments and do that.
Rails 7 changed the way ActionText attachments work, so we'll be writing a Rake task to walk through each of the embeds and update them with the correct Signed GlobalID.
Ever needed to modify the HTML that ActionText renders? We can override the ActionText::Content class to modify the way HTML formatting works to customize the output. For example, we can add rel="noopener nofollow" to any anchor tags in the content.
ActionText is secure by default, but sometimes you need more control over the sanitization. That's where custom sanitizers and scrubbers come in and we'll learn how to use these.
In this episode, we will extend Trix by adding a text highlighting feature.
