#aggregate_validations(*lambdas) ⇒ Object

This method will combine all parameter validation errors into a single error hash Warning: If the same key exists in two validations the last one wins You pass it a lambda that validates parameters. EXAMPLE: errors = validate_workflows(-> = validate_params(params_),

-> {@update_location_wf = update_location_wf.new(params_)})
