[lobo]

my question is possible pass the $ref validate a component and the component validate the $ref sometime like this https://stackoverflow.com/questions/45187857/passing-refs-content-from-a-child-to-another-vuejs-child-component/45188166

<q-input v-model=“datos.correo” ref=“refCorreo” :rules="[ val => val !== null || ‘Debe escribir un correo o un número de celular’]" />
<ComponentExample :parentRefs="$refs.refCorreo" /> or call in the componente sometime like this this.$parent.$refs.refCorreo.validate()
