Constants

Point	=	Struct.new(:x, :y)

UnknownAttributeError	=	ActiveModel::UnknownAttributeError
	Raised when unknown attributes are supplied via mass assignment. `class Person include ActiveModel::AttributeAssignment include ActiveModel::Validations end person = Person.new person.assign_attributes(name: 'Gorby') # => ActiveModel::UnknownAttributeError: unknown attribute 'name' for Person.`
MigrationProxy	=	Struct.new(:name, :version, :filename, :scope) do def initialize(name, version, filename, scope) super @migration = nil end def basename File.basename(filename) end def mtime File.mtime filename end delegate :migrate, :announce, :write, :disable_ddl_transaction, to: :migration private def migration @migration \|\|= load_migration end def load_migration require(File.expand_path(filename)) name.constantize.new(name, version) end end
	MigrationProxy is used to defer loading of the actual migration classes until they are needed
