How do I update middleware for Rails 3?

Rails
1

Hello,

I’m updating an application to Rails 3 that has Uploadify implemented as
described by John Nunemaker here:
http://railstips.org/blog/archives/2009/07/21/uploadify-and-rails23/

My questions are:

  1. Where should middleware live in a Rails 3 application?
    app/middleware?

  2. Is the middleware path loaded in config/application.rb? Or is there a
    way to do it in config/environment.rb?

  3. What should I update the following code to to make it work in Rails
    3?

config/initializers/session_store.rb

ActionController::Dispatcher.middleware.insert_before(
ActionController::Session::CookieStore,
FlashSessionCookieMiddleware,
ActionController::Base.session_options[:key]
)

Specifically, how do I call each of the following:

  • ActionController::Dispatcher.middleware.insert_before
  • ActionController::Session::CookieStore
  • ActionController::Base.session_options[:key]

I’ve looked through the Rails 3 source, and tried various combinations
e.g., ActionDispatch::Cookies, ActionDispatch::Middleware::Cookies,
ActionController.cookies, etc., but to no avail.

Thanks, Patrick

hi, Patrick.
Try the following code, it works for me.

replace

config/initializers/session_store.rb

ActionController::Dispatcher.middleware.insert_before(
ActionController::Session::CookieStore,
FlashSessionCookieMiddleware,
ActionController::Base.session_options[:key]
)

with

Rails.application.config.middleware.insert_before(Rails.application.config.session_store,
FlashSessionCookieMiddleware,
Rails.application.config.session_options[:key])
