nestedAttribute.coffee

    # Example usage
    #  @model.setNestedAttribute parent: 'foo', property: 'bar', value: 'catz', silent: true
    setNestedAttribute: (options) ->
      parent = options.parent
      value = options.value
      property = options.property
      silent = options.silent

      date_data = @get(parent) || {}
      date_data[property] = value
      @set(parent, date_data, {silent: silent})
      console.log date_data
