Quoting Bharat Ruparel <firstname.lastname@example.org>:
Upgrading to Rails 2.3.8 from 2.3.2 has broken views in my application.
Rails 2.3.8 is a stepping stone to Rails 3 with lots of deprecation warnings
and some actual changes. And not all Gems and plugins are compatible with
it. I suggest migrating from 2.3.2 to 2.3.5 first. Then try going to 2.3.8.
And expect problems in both your code and others' code. I.e., allocate time
to do the conversion and accept that you may have to wait for compatible
gems/plugins to be available. (Or figure the necessary patches and submit
them to the author.)
