Instance Public methods

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>'

def raw(stringish) stringish.to_s.html_safe end

safe_join(array, sep = $,)Link

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

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

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

to_sentence(array, options = {})Link

Converts the array to a comma-separated sentence where the last element is joined by the connector word. This is the html_safe-aware version of ActiveSupport’s Array#to_sentence.
