Vue模型:绑定嵌套数据

如何将以下嵌套数据与 v-model ?

<div v-for="(frame, i) in frames" :key="frame.id" class='well'>
  <div v-for="(value, key) in frame" :key="key">
    {{ key }}:
    <input type="text" :v-model="frame[i].key" :id="key.id">
  </div>
</div>

把这些数据存储在 this.frames :

[{"x": 0, "y" : 0, "width": 10, "height": 10, "direction": "down", "div": "header", "page_number": 1}]
