# module ActionView::Helpers::OutputSafetyHelper

### Public Instance Methods

raw(stringish) click to toggle source

This method outputs without escaping a string. Since escaping tags is now default, this can be used when you don't want Rails to automatically escape tags. This is not recommended if the data is coming from the user's input.

For example:

    raw @user.name
    # => 'Jimmy <alert>Tables</alert>'

    # File lib/action_view/helpers/output_safety_helper.rb, line 16
    def raw(stringish)
      stringish.to_s.html_safe
    end

safe_join(array, sep=$,) click to toggle source

This method returns an HTML safe string similar to what `Array#join` would return. The array is flattened, and all items, including the supplied separator, are HTML escaped unless they are HTML safe, and the returned string is marked as HTML safe.

    safe_join(["<p>foo</p>".html_safe, "<p>bar</p>"], "<br />")
    # => "<p>foo</p>&lt;br /&gt;&lt;p&gt;bar&lt;/p&gt;"

    safe_join(["<p>foo</p>".html_safe, "<p>bar</p>".html_safe], "<br />".html_safe)
    # => "<p>foo</p><br /><p>bar</p>"

    # File lib/action_view/helpers/output_safety_helper.rb, line 31
    def safe_join(array, sep=$,)
      sep = ERB::Util.unwrapped_html_escape(sep)

      array.flatten.map! { |i| ERB::Util.unwrapped_html_escape(i) }.join(sep).html_safe
    end
