end

#guard(name, error_extra: {}) { ... } ⇒ void

This method returns an undefined value.

Register a group-level guard. Semantics match the per-command ‘guard` DSL — `:no_change` is recognized as the magic name that raises NoChangeTransition on failure.

Parameters:

  • name (Symbol) —

    the guard name

  • error_extra (Hash, Proc) (defaults to: {}) —

    extra error context

Yields:

  • Block returning true if the guard passes
