rails--rails/railties/CHANGELOG.md

• Set Rails console to use log formatter and log level as specified for the given environment.

  Fixes #15470.

  Jacob Evelyn

• Add config/initializers/active_record_belongs_to_required_by_default.rb

  Newly generated Rails apps have a new initializer called active_record_belongs_to_required_by_default.rb which sets the value of the configuration option config.active_record.belongs_to_requred_by_default to true when ActiveRecord is not skipped.

  As a result, new Rails apps require belongs_to association on model to be valid.

  This initializer is not added when running rake rails:update, so old apps ported to Rails 5 will work without any change.

• delete operations in configurations are run last in order to eliminate 'No such middleware' errors when insert_before or insert_after are added after the delete operation for the middleware being deleted.

  Fixes: #16433.

• Use local variables in _form.html.erb partial generated by scaffold.

  Andrew Kozlov

• Add config/initializers/callback_terminator.rb

  Newly generated Rails apps have a new initializer called callback_terminator.rb which sets the value of the configuration option config.active_support.halt_callback_chains_on_return_false to false.

  As a result, new Rails apps do not halt callback chains when a callback returns false; only when they are explicitly halted with throw(:abort).

  The terminator is not added when running rake rails:update, so returning false will still work on old apps ported to Rails 5, displaying a deprecation warning to prompt users to update their code to the new syntax.
