# Thoughts on using active model validations for service objects...
#
# NOTE: I edited this code in the GIST - there are probably errors. I even converted
# to old hash syntax for Pat and Warren.
#
# So this is a service or command object, something straight out of a method object refactoring.
# You create it, then execute it (call `call`). I've used `ActiveModel::Validations` to define validations
# that need to be met before the command is run.
#
# It would be perfectly reasonable to define call so it calls valid first, and returns true or false

Some notes:

• This is very much a skeleton that goes JUST as far as we needed it to.
• It's using the redirect method for the return url, rather than the proxying style. I need to think a little more about whether the POST and proxy our redirect to the client is better/worse.
• This may not be a super correct AM integration, like I said, JUST as far as we needed to go :)
