I have a child component
<v-form ref="form" v-model="valid" lazy-validation>
<v-select v-model="test" :items="data" :rules="[v => !!v || 'Required']"></v-select>
</v-form>
If i try this.$refs.form.validate() in child component it is validating.
And in parent component, i have a simple button
<v-btn color="primary" @click="save()">save</v-btn>
On clicking on the button i can call the child component method to get the validation status of the child form. It works great.
Now i would like to disable the button, if the child form is not valid. What is the best way to do this?

The validity of your form is updated live by vuetify, via the v-model property of the v-form. You just need to bind this property such that it's accessible from wherever you need it. When a property like this is used in more than one component, it's shared state. I much prefer getting shared state out of Vue components, and putting it in a global object that I like to call vueStore. There are other ways to share state, but I like this way !
var vueStore =
valid:false
Vue.component('my-child', 'Required']"></v-select>
</v-form>`,
data()
return items:['','red','green','blue'],
vueStore:vueStore,
test:null
)
var vm = new Vue(
el:'#app',
data:vueStore:vueStore,
methods:
save()
alert("saving...")
)<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.18/vue.js"></script>
