Using ActionText for Rich Text Editing in Rails 6
Rich text editing is an essential feature in many web applications, allowing users to create and edit content with formatting options similar to a word processor. In Rails 6, ActionText is introduced as a built-in rich text editor solution, making it easier than ever to implement this functionality in your application.
Getting Started
ActionText is designed to work seamlessly with the Trix editor, a lightweight and customizable WYSIWYG editor. To start using ActionText, you need to have Rails 6 or later installed in your development environment.
To add ActionText to your Rails application, simply run the following command in your project’s root directory:
$ bundle add actiontext
This command will add the ActionText gem to your application and install the necessary dependencies. After that, run the database migrations to create the required tables for ActionText:
$ bin/rails action_text:install
$ bin/rails db:migrate
Usage
Once ActionText is installed and migrated, you can start using it within your models. Simply associate the rich text content with a model using the has_rich_text
method.
# app/models/article.rb
class Article < ApplicationRecord
has_rich_text :content
end
This will provide you with all the necessary methods to handle rich text content for the associated model. For example, to render the rich text content in a view, you can use the content.to_html
method:
<%= @article.content.to_html %>
ActionText also provides a range of methods to customize the Trix editor’s behavior and appearance. You can find more details in the official Rails documentation.
Advanced Features
One of the powerful features of ActionText is the ability to attach files to rich text content. This can be done using the has_many_attached
method, which allows you to associate multiple files with a specific rich text attribute.
# app/models/article.rb
class Article < ApplicationRecord
has_rich_text :content
has_many_attached :images
end
In your view, you can then easily render the attached images using the image_tag
helper:
<% @article.images.each do |image| %>
<%= image_tag image %>
<% end %>
This way, you can let users easily enhance their content by adding images alongside the rich text they provide.
Conclusion
ActionText introduces a streamlined approach to rich text editing in Rails 6. With its seamless integration with the Trix editor, it makes implementing and managing rich text content a breeze. Whether you need to enable rich text editing for blog articles, forum posts, or any other content in your application, ActionText provides a reliable and user-friendly solution that will enhance the user experience.
So, give ActionText a try in your next Rails 6 project and take your application’s content editing capabilities to the next level!
