Configure Rails to output HTML output instead of XHTML

Question

How do I configure Ruby on Rails to output standard HTML code instead of XHTML when using helpers (form, javascript, css, etc.)?

I don't want to have the slash at the end:

<input name="email" type="text" />

Answer 1

This answer is contained in the link provided by MarkusQ, but I figured I could spell it out exactly.

You have to modify the code than renders all tags, you can do that by including the following code into something like lib/dont_use_xhtml.rb

module ActionView::Helpers::TagHelper
  alias :tag_without_backslash :tag
     def tag(name, options = nil, open = true, escape = true)
        tag_without_backslash(name, options, open, escape)
     end 
  end 

Answer 2

The solution does not work with the latest version of Rails. Some helpers will override the open method argument of 'open' to 'false'.

The following works for me in Rails 2.3.5:

module ActionView::Helpers::TagHelper
  def tag_with_html_patch(name, options = nil, open = true, escape = true)
    tag_without_html_patch(name, options, true, escape)
  end
  alias_method_chain :tag, :html_patch
end

Put that into an initializer.
