Instance Method Details

#to_html_options(double_quotes = true) ⇒ Object

Makes this hash fit to be put into a tag. 1, b: “two”, c: true, d: false.to_html_options # => ‘a=“one” b=“two” c’ Note that true and false are special-cased, true to allow for attributes that do not have a value and false for convenience, to allow for, e.g., inline conditionals.
