title: Vuetify Datepicker format
body: <p>I have a Vuetify Datepicker:</p>
  
  <pre><code>&lt;v-menu
      v-model="menu1"
      :close-on-content-click="false"
      max-width="290"
  &gt;
      &lt;template v-slot:activator="{ on }"&gt;
      &lt;v-text-field
          v-model="editedItem.Eintrittsdatum"
          clearable
          color="primary"
          label="Eintrittsdatum"
          v-on="on"
      &gt;&lt;/v-text-field&gt;
      &lt;/template&gt;
      &lt;v-date-picker
          v-model="editedItem.Eintrittsdatum"
          @change="menu1 = false"
          locale="de"
      &gt;&lt;/v-date-picker&gt;
  &lt;/v-menu&gt;
  </code></pre>
  
  <p>The return value is the normally formatted date (yyyy-mm-dd). This is also the data I would like to save in the v-model (and eventually inside the data object). However, just for the eye-candy I would like to display the value of the text-field with a different format.</p>
  
  <p>I have created a little function:</p>
  
  <pre><code>formatDate(date) {
      return date ? moment(date).format("L") : "";
  }
  </code></pre>
  
  <p>Is there a way to call this function to overwrite the displayed value?</p>
