A few Rails 3.2 fixes

[mperham]

Here's a set of small commits which fix a number of bugs and deprecation warnings which show up in the new Rails 3.2 release.

I verified the test suite passes on Rails 3.2 and 3.1.

Forgot to mention, there is one bug in thoughtbot/shoulda#173 that breaks two tests with an error about "primary_key_name". Once I patched that bug, the tests pass.

+1 linking to your fork in my gem file worked to get my server and console started

+1 also using @mperham 's fork to make it work

At config/environments/development.rb I have to write config.reload_classes_only_on_change = false, if I set it to true then code in app/admin/* is not reloaded and I have to restart the server. Is that normal? Using b5b97e1

I am seeing the exact same thing with Grape that I am using for our API on
WODstack so I think it has to do with rails not picking up the reload
requests for other stuff than the rails internals. I've tried every single
combination of reloading libs/folders and files so if anyone find a good
workaround for this please tell me :)

Change the Gemfile to:
gem 'activeadmin', :git => 'git://github.com/gregbell/active_admin.git'

then $bundle install

It worked for me.

@folano
Thank you for your help. Didn't work though. That is what I have in my Gemfile. I guess it is something else. The classes should not be cached cause my config is correct
config.cache_classes = false
config.action_controller.perform_caching = false

I don't know what else to do.

Thank you anyway.

A temporal workaround that works for me till we figure out the real problem:

# config/environments/development.rb`
config.reload_classes_only_on_change = true
config.watchable_dirs[File.join(config.root, "app/admin")] = ["rb"]
