config/environment.rb (or for Redmine, this can go in config/additional_environment.rb):

config.middleware.insert_before("ActionController::Session::CookieStore", "FlashSessionCookieMiddleware")

app/middleware/flash_session_cookie_middleware.rb:

JavaScript:

In the section of your layout:

<% csrf_meta_tag %>
