How to change validation messages on forms

You have to specify the translation after the attribute

es:
  activerecord:
    models:
      announcement: "Anuncio"
    attributes:
      announcement:
        title: "Título"   # <= here
    errors:
      models:
        announcement:
          attributes:
            title:
              blank: "no puede estar vacío."
