A bug surfaced in RC1 that makes `rake test:prepare` fail when used in conjunction with ActiveRecord''s table_name_prefix option. It fails to add entries to the schema_migrations table, and test:prepare now checks for pending migrations. Since no entries are added, it fails each time. I''ve created a pull request, with test and a sample app that demonstrates the problem. Any feedback or help is appreciated as anyone using table_name_prefix will be unable to run their tests in RC1. Here is a link to the issue and PR: https://github.com/rails/rails/issues/10411 Here is the sample project: https://github.com/kstevens715/testapp Thank you for any help! -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
