Set_flash_message: Notice ,: if_navigational_format is signed? Sign_in (resource_name, processing) response_with resource ,: location = & gt; After_sign_up_path_for (resource) and set_flash_message: notice, "sign_up_but _ # {resource.inactive_message}" if is_navigational_format? Expire_session_data_after_sign_in! Reply with Resource: Location = & gt; (Resource) for after_inactive_sign_up_path_ end other clean_up_passwords resource end-end processing with resource response
