[magic] Repeated keys error

[davidstackio]

When using magic to create forms, I have a repeated key property stock_keys.

On the form I have multiple checkboxes that look like this:

<input type="checkbox" name="stock_keys" value="ag1kZXZ-cG9ldC1wb2VtchILEgVTdG9jaxiAgICAgIi2Cww">

When submitting the form, this is the error I get:

BadValueError: Expected list or tuple, got Key('Stock', 4626195173867520)

Using version 3.2.3

I have resolved the error by using model_form from my own fork of wtforms-appengine and my own custom multiple_key_checkbox_field html macro in macro/forms.html script:

# macro key_checkbox_field(field)
  <div class="form-group {{'has-error' if field.errors}}">
    {{field.label(class='control-label')}}
    {{field_optional(field)}}
    {{field_description(field)}}
    # for key, value in field.choices
      <div class="checkbox">
        <label>
          <input type="checkbox" name="{{field.name}}" value="{{key.id() if key else ''}}"
            # if field.data and (key == field.data or key in field.data)
              checked
            # endif
          > {{value}}
        </label>
      </div>
    # endfor
    {{field_errors(field)}}
  </div>
# endmacro

# macro multiple_key_checkbox_field(field)
  {{key_checkbox_field(field)}}
# endmacro

Using the above, the checkboxes on the forms look like this:

<input type="checkbox" name="stock_keys" value="6430218877140992">

I am more than happy to create a PR to add this functionality to the core of gae-init, but I'm not sure how to update the magic.

Still an issue...
Would love to use 'repeating' KeyProperty fields so I can have multiple children of the same type (select using a dropdown or create on the fly) but at the moment getting
BadValueError: Expected list or tuple, got Key('Dimension', 4889528208719872)
