Class Method Details

.load_tables ⇒ void

apply db/schema.sql through the adapter's official client; a tree with no schema dump loads nothing.

Raises:

  • (RuntimeError) —

    the client exits non-zero — its output is the message

def self.load_tables
  return unless File.exist?("db/schema.sql")

  apply_file("db/schema.sql")
end

.reject_legacy_layout ⇒ void

refuse to load while the legacy config/ schema layout is still on disk. A silent skip would boot on stub tables and pass every non-DB case, so the leftover files raise.

Raises:

  • (RuntimeError) —

    config/schema.sql or config/views exists
