Instance Public methods
raw(stringish) Link
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>'
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><br><p>bar</p>"
safe_join([tag.p("foo"), tag.p("bar")], tag.br)
# => "<p>foo</p><br><p>bar</p>"
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.
