PolymerJS：如何输出模型数据？

Question

Is there a way to output all model data of polymer elements?

I would like to output each property and their value to the view.

I know vue accomplishes this, by using

{{ $data | json }}

But Vue also has a data attribute that is dumpable . Not sure if it is even possible in polymer to dump every property and their value into the view.

I'd like to use something similar with polymer. But how?

I know doing something like this doesn't work:

{{ $properties }}

As far as I know, there is no filters in data bindings in PolymerJS like vue has.

But you can use so called Computed binding :

<dom-module id="view">

  {{dump(model)}}

  <script>
    Polymer({
      is: 'view',
      properties: {
        model: Object       
      },
      dump: function(model) {
        return JSON.stringify(model, null, ' ');
      }
    });
  </script>

</dom-module>
