*   Change `form_with` to generates ids by default.

    When `form_with` was introduced we disabled the automatic generation of ids
    that was enabled in `form_for`. This usually is not an good idea since labels don't work
    when the input doesn't have an id and it made harder to test with Capybara.

    You can still disable the automatic generation of ids setting `config.action_view.form_with_generates_ids`
    to `false.`
