Vue路由器将对象作为道具传递

我有以下小提琴https://jsfiddle.net/91vLms06/1/

const CreateComponent = Vue.component('create', {
    props: ['user', 'otherProp'],
  template: '<div>User data: {{user}}; other prop: {{otherProp}}</div>'
});

const ListComponent = Vue.component('List', {
  template: '<div>Listing</div>'
});

const app = new Vue({
    el: '#app',
  router: new VueRouter(),
  created: function () {
    const self = this;
        // ajax request returning the user
    const userData = {'name': 'username'}
    self.$router.addRoutes([
        { path: '/create', name: 'create', component: CreateComponent, props: { user: userData }},
      { path: '/list', name: 'list', component: ListComponent },
      { path: '*', redirect: '/list'}
    ]);
    self.$router.push({name: 'create'}); // ok result: User data: { "name": "username" }; other prop:
    self.$router.push({name: 'list'}); // ok result: Listing
    // first attempt
    self.$router.push({name: 'create', props: {otherProp: {"a":"b"}}}) // not ok result: User data: { "name": "username" }; other prop:
    self.$router.push({name: 'list'}); // ok result: Listing
    // second second
    self.$router.push({name: 'create', params: {otherProp: {"a":"b"}}}) //not ok result: User data: { "name": "username" }; other prop:
  }
});

如您所见CreateComponent，user当我初始化路由时，我正转到。

稍后，我需要传递另一个属性，otherProp并仍然保留user参数。当我尝试执行此操作时，我发送的对象不会传递给组件。

如何通过otherProp和仍然保留user？

的真正目的otherProp是用表单中的数据填充表单。在清单部分中，有一个对象，当我单击“编辑”按钮时，我想用清单中的数据填充表单。
