with_role returns readonly models in Rails 4

[D1plo1d]

Rails 4 now marks any model retrieved by a query including a join as readonly. This in turn causes a ActiveRecord::ReadOnlyRecord to be raised whenever a resource is returned from with_role.

The problem seems to be here: https://github.com/EppO/rolify/blob/master/lib/rolify/adapters/active_record/resource_adapter.rb#L7

This can be fixed by adding a .readonly(false) to the query. I'm not sure if this should be patched in rolify.

Nice catch, I'll write a failing spec scenario and investigate for a workaround. A cleaner way seems to chain a select method to the query on the resource fields.
