Trix

ruby
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

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.

Default

false

Possible values

true, false

attchments_disabled

Hides the attachments button from the Trix toolbar.

Default

false

Possible values

true, false

hide_attachment_filename

Hides the attachment's name from the upload output in the field value.

Default

false

Possible values

true, false

hide_attachment_filesize

Hides the attachment size from the upload output in the field value.

Default

false

Possible values

true, false

hide_attachment_url

Hides the attachment URL from the upload output in the field value.

Default

false

Possible values

true, false

attachment_key

Enables file attachments.

Default

nil

Possible values

nil, or a symbol representing the has_many_attachments key on the model.

File attachments

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

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

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

ruby
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).

ruby
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.
