Rails 3.0使用来自application_helper的sanitize和simple_format

Question

在我看来，我想渲染(和截断)一些段落与安全的html标签，如p i br等，我使用这个代码:

- @last_testimony.each do |last_testimony|
  = sanitize(simple_format(truncate(last_testimony.description, :length => 25)), :tags => %w(p i br b))

用html标签呈现段落。

但是当我将代码传递给application_helper

时

def paragraph(text, length)
  "#{sanitize(simple_format(truncate(text, :length => length)), :tags => %w(p i br b))}"
end

With this view

- @last_testimony.each do |last_testimony|
  = paragraph(last_testimony.description, 10)

它呈现

< p>My paragraph < /p> 

如何修复?是否有更好的方法来呈现带有安全标签的段落?

Answer 1

一些方法:

1。

- @last_testimony.each do |last_testimony|
  = raw paragraph(last_testimony.description, 10)

2。

def paragraph(text, length)
  "#{sanitize(simple_format(truncate(text, :length => length)), :tags => %w(p i br b))}".html_safe
end
