从“在中重复dom”对话框编辑firebase对象

我正在尝试编辑图纸对话框中集合中的firebase对象

我正在访问e.model对话框按钮的点击功能中的对象。但是我如何从对话框中回写它呢

<firebase-collection id="fbAccounts"
                location="https://xxx.firebaseio.com/accounts"
                data="{{accounts}}">
</firebase-collection>

请提供一些代码片段，以便更容易地帮助您：感谢您提供代码，但您如何“选择”要编辑的帐户？我在代码中看不到您在openEditDialog中“选择”实际帐户的位置。我有一个存储在数据中的e.model对象。@JoergHerbarth您使它工作了吗？我使用dom重复显示项目，然后使用对话框进行编辑。在阵列中实时编辑，但在firebase中不更新

<paper-icon-button icon="editor:mode-edit" on-click="openEditDialog"></paper-icon-button>

<paper-dialog id="editContact">
  <h2>Edit Account</h2>
  <paper-input id="companyname" label="Company Name" value="{{data.accounts.name}}"></paper-input>
  <paper-input id="street" label="Street" value="{{data.accounts.street}}"></paper-input>
  <div class="horizontal layout">
    <paper-input id="postalcode" label="Postal Code" size="8" value="{{data.accounts.postalcode}}"></paper-input>
    <paper-input id="city" style="padding-left: 12px" label="City" value="{{data.accounts.city}}"></paper-input>
  </div>
  <paper-input id="country" label="Country" value="{{data.accounts.country}}"></paper-input>
  <div class="buttons">
    <paper-button dialog-dismiss>Cancel</paper-button>
    <paper-button dialog-confirm on-click="saveEditAccount">Save</paper-button>
  </div>
</paper-dialog>

Polymer({

  is: 'accounts-view',
  properties: {
    data: {
      type: Object,
      notify: true
    }
  },

  openEditDialog: function(e) {
    this.data = e.model;
    this.$.editContact.open();
  },
  deleteAccount: function(e) {
    this.$.fbAccounts.remove(this.data.accounts);
  },
  saveEditAccount: function() {
    var account = this.$.fbAccounts.getByKey(this.data.accounts.__firebaseKey__);
    console.log(account);
  });
  }

});
