如何在meteor中保存从mongodb生成的可满足编辑的表单？

Forms = new Mongo.Collection('forms');

<template name="formTemplate">
  {{#each forms}}
    {{#if editing}}
      <input type="text" value="{{name}}" />
      <button class="save">保存</button>
    {{else}}
      <span>{{name}}</span>
      <button class="edit">编辑</button>
    {{/if}}
  {{/each}}
</template>

Template.formTemplate.events({
  'click .edit'(event, template) {
    const formId = this._id;
    Forms.update(formId, { $set: { editing: true } });
  },
  'click .save'(event, template) {
    const formId = this._id;
    const newName = template.find('input').value;
    Forms.update(formId, { $set: { name: newName, editing: false } });
  }
});

Template.formTemplate.onCreated(function() {
  this.subscribe('forms');
});

Meteor.publish('forms', function() {
  return Forms.find();
});

Meteor.startup(function() {
  if (Forms.find().count() === 0) {
    Forms.insert({ name: '表单1', editing: false });
    Forms.insert({ name: '表单2', editing: false });
    Forms.insert({ name: '表单3', editing: false });
  }
});
