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: 
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.
