Cameron Pope asked Yehuda Katz

How do I set up rails 3 to use jquery instead of prototype, ideally so the default javascript tag references jquery?

You need to do two things. First, remove the default JavaScript files from public/javascripts and replace them with jquery.js from http://code.jquery.com/jquery-1.4.2.min.js (as jquery.js) and rails.js from http://github.com/rails/jquery-ujs/raw/59dd91d945570391f905b1e40444e5921dbc2b8f/src/rails.js.

Next, do the following in an initializer

module ActionView::Helpers
  remove_const :JAVASCRIPT_DEFAULT_SOURCES
  JAVASCRIPT_DEFAULT_SOURCES = %w(jquery.js rails.js)

  reset_javascript_include_default
end
