Instance Method Details

#raw(stringish) ⇒ Object

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 = $,) ⇒ Object

This method returns a html safe string similar to what Array#join would return. All items in the array, 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>"
