I have a gem, and part of the gem is a piece of rack middleware. In
Rails 2.3, I could make the gem set up the middleware without adding
anything to config/*.rb in the app. I did this with the following
line:
ActionController::Dispatcher.middleware.use ''MyMiddleware''
But in Rails 3, this doesn''t work.
I''ve tried putting the following into the gem''s
lib/gem_name.rb:
Rails.application.config.middleware.use ''MyMiddleware''
But now when I run `rake middleware` I get "undefined method
`config''
for nil:NilClass" which means that Rails.application is nil.
I successfully used the middleware by with an initializer or something
in the app''s config directory, but I''d like to do this in the
gem. Is
this possible?
