DEPRECATION WARNING when using mongomapper and Rails 3.2.3 / patch

[nachbar]

I am getting a deprecation warning whenever I start rails server or console. The exact message is:

DEPRECATION WARNING: The InstanceMethods module inside ActiveSupport::Concern will be no longer included automatically. Please define instance methods directly in MongoMapper::Plugins::AutoIncrement instead. (called from require at /Users/nachbar/.rvm/gems/ruby-1.9.2-p320@global/gems/bundler-1.1.3/lib/bundler/runtime.rb:68)

Following those instructions (just moving the instance methods outside of InstanceMethods, but also removing the InstanceMethods module definition), the deprecation message no longer appears. The patch is:

From: James Nachbar <nachbar@plastic.org>

Subject: [PATCH] Removed definition of InstanceMethods module, defining
 instance methods directly in ::AutoIncrement, to prevent
 deprecation warning

@nachbar thank you for reporting that! Could you update your Gemfile gem "mongomapper_id2", "~> 0.0.5".

Cheers

That fixed it!

However, interestingly, when I put that in the Gemfile, it also updated the mongo and bson drivers to 1.6.3 (that release of mongo was released today!) and that seriously broke my setup. Any attempt to delete an object with mongo_mapper caused the server to hang. However, fixing the mongo driver to 1.6.2 fixed that problem, and all of my tests still pass using the 0.0.5 version of mongomapper_id2.

Thanks again!
