Trix

field :body, as: :trix

The Trix field renders a WYSIWYG Editor and can be associated with a string or text column in the database. The value stored in the database will be the editor's resulting HTML content.

Trix field is hidden from the Index view.

Options

-> always_show

By default, the content of the `Trix` field is not visible on the `Show` view; instead, it's hidden under a `Show Content` link that, when clicked, displays the content. You can set Markdown to display the content by setting `always_show` to `true`.

File attachments

WARNING

You must manually require activestorage and image_processing gems in your Gemfile.

# Active Storage makes it simple to upload and reference files
gem "activestorage"

# High-level image processing wrapper for libvips and ImageMagick/GraphicsMagick
gem "image_processing"

Trix supports drag-and-drop file attachments. To enable Active Storage integration, you must add the attachment_key option to your Trix field.

field :body, as: :trix, attachment_key: :trix_attachments

That attachment_key has to have the same name as the model.

class Post < ApplicationRecord
  has_many_attached :trix_attachments
end

Now, when you upload a file in the Trix field, Avo will create an Active Record attachment.

Disable attachments

You may want to use Trix only as a text editor and disable the attachments feature. Adding the attachments_disabled option will hide the attachments button (paperclip icon).

field :body, as: :trix, attachments_disabled: true

Remove attachment attributes

By default, Trix will add some meta-data in the editor (filename, filesize, and URL) when adding an attachment. You might not need those to be present in the document. You can hide them using hide_attachment_filename, hide_attachment_filesize, and hide_attachment_url.
