Monkey patching away default_scope

I was recently working on a Spree store that needed to remove a default scope that was created by an extension. Lots of Google searching did not yield an answer, so I dove into the ActiveRecord source to figure out how default_scope was implemented. It turns out that the default scope is stored as an array in a class variable default_scopes. So removing the default scope was as simple as

Spree::User.class_eval do
  self.default_scopes = []
end

I’m sure this depends on ensuring that this code executes after any default scopes have been created, so that’s something to check if you try this out and find that it does not work.
