Instance Method Details

#rich_textarea_tag(name, value = nil, options = {}, &block) ⇒ Object Also known as: rich_text_area_tag

Returns a trix-editor tag that instantiates the Trix JavaScript editor as well as a hidden field that Trix will write to on changes, so the content will be sent on form submissions.

#### Options

  • :class - Defaults to “trix-content” so that default styles will be applied. Setting this to a different value will prevent default styles from being applied.

  • [:data][:direct_upload_url] - Defaults to rails_direct_uploads_url.

  • [:data][:blob_url_template] - Defaults to ‘rails_service_blob_url(“:signed_id”, “:filename”)`.

#### Example

rich_textarea_tag "content", message.content
# <input type="hidden" name="content" id="trix_input_post_1">
# <trix-editor id="content" input="trix_input_post_1" class="trix-content" ...></trix-editor>

rich_textarea_tag "content", nil do
  "<h1>Default content</h1>"
end
# <input type="hidden" name="content" id="trix_input_post_1" value="&lt;h1&gt;Default content&lt;/h1&gt;">
# <trix-editor id="content" input="trix_input_post_1" class="trix-content" ...></trix-editor>
