mysql2 adapter not loaded when railtie runs

[ak47]

I have a new Rails 4.2.1 app, followed usual Readme setup with Gemfile and placed "include ActiveUUID::UUID" line in my model. However, every time I run specs or rails console, the activeuuid patches have not been applied.

I added a break to the .apply method in ActiveUUID::Patches, and the mysql2 adapter,
ActiveRecord::ConnectionAdapters::Mysql2Adapter
is not defined at that point.

The result, if I start a console, is that I need to do a manual "ActiveUUID::Patches.apply!" to get things working.

Anybody else see this? Am I doing something wrong?

Odd part is, I have a Rails 4.2.0 app using activeuuid and all is good.

sort of solved the problem with a bit of hackery,

adding an initializer with:

ActiveRecord::Base.connection

Forces AR to load and the railtie works as designed.
Maybe this is just a dev/test env thing - not sure yet.

I am seeing the exact same problem with a Rails 4.2.1 application in development environment.
I have added a migration to add a uuid column, and the migration fails because the previous run of ActiveUUID::Patches.apply! did not patch the respective classes, due to ActiveRecord::ConnectionAdapters::Mysql2Adapter not being defined.

For what it's worth:
Adding a simple ActiveRecord::Base, to initiate ActiveRecord class loading, before this line solves the issue for me in Rails 4.2.1.
