Action Text Content
ActionText::Content
類別包裝 HTML 片段,以新增對解析、渲染和序列化之支援。它可以用於提取連結和附件,將片段轉換為純文字,或將片段序列化到資料庫。
ActionText::RichText
記錄將 body
屬性序列化為 ActionText::Content
。
class Message < ActiveRecord::Base
has_rich_text :content
end
message = Message.create!(content: "<h1>Funny times!</h1>")
body = message.content.body # => #<ActionText::Content "<div class=\"trix-conte...">
body.to_s # => "<h1>Funny times!</h1>"
body.to_plain_text # => "Funny times!"

傳回內容中標記的純文字版本,移除標籤但編碼 HTML 實體。

content.to_plain_text # => "safeunsafe"
注意:傳回的字串不是 HTML 安全的,不應在瀏覽器中呈現。
content = ActionText::Content.new("<script>alert()</script>")
content.to_plain_text # => "<script>alert()</script>"
