I've added a commit that does this: https://github.com/jeremyevans/sequel/commit/f06491f95a6f7d2bf97479336e18b42dbe5c8593 As the commit message states, you can now support the mock adapter in external adapters using the following API in the shared adapter (code in file sequel/adapters/shared/mydb.rb module Sequel::MyDB Sequel::Database.set_shared_adapter_scheme :mydb, :self def self.mock_adapter_setup(db) # ... end module DatabaseMethods # ... end module DatasetMethods # ... end end Thanks, Jeremy -- You received this message because you are subscribed to the Google Groups "sequel-talk" group.
