清理不适用于'p'和'br'标签

Question

我有一个文字：

<p>This is some text <br/> with two<br /> lines</p>

这是我期望的输出：

This is some text <br/> with two<br /> lines

我在我的模型中使用帮助器（我知道，但这只是我想要的方式）：

result = ActionView::Base.full_sanitizer.sanitize(text, :tags => ['br'])

但它不起作用。我得到的结果没有任何标签：

This is some text with two lines

我也尝试过：

result = ActionView::Base.full_sanitizer.sanitize(text, :tags => %w(br))

但它不起作用。

出了什么问题，如何检索包含<br/>标签的文字？

Answer 1

我想你试试这个

text = "<p>This is some text <br/> with two<br /> lines</p>"
#=> "<p>This is some text <br/> with two<br /> lines</p>" 
result = ActionController::Base.helpers.sanitize(text, :tags => ['br'])
#=> "This is some text <br /> with two<br /> lines"
