在Rails控制器中使用sanitize [英] Using sanitize within a Rails controller

问题描述

我试图在控制器中调用 sanitize 。这里是我尝试：

I'm trying to call sanitize within a controller. Here's what I tried:

class FooController < ApplicationController
  include ActionView::Helpers::SanitizeHelper
  # ...
end

但是，我收到此错误：

undefined method `white_list_sanitizer' for FooController:Class

我搜索过，人们建议切换include行以包含 ActionView :: Helpers ，但会导致此错误：

I searched around and people recommended switching the include line to include ActionView::Helpers, but that results in this error:

undefined method `url_for' for nil:NilClass

调用 sanitize 的正确方法是什么？我使用Rails 2.3.5。

What's the correct way to call sanitize? I'm using Rails 2.3.5.

推荐答案

你可以使用 ActionController :: Base.helpers 内部操作方法：

you can use this ActionController::Base.helpers inside action method:

class SiteController < ApplicationController
  def index
    render :text => ActionController::Base.helpers.sanitize('<b>bold</b>')
  end
end

希望这有助于
