Question

我有Extent的aredux-orm模型，如下所示：

const { string, number, arrayOf, oneOfType, instanceOf } = PropTypes

export default class Extent extends ValidatingModel {}

Extent.fields = {
  xmin: attr(),
  ymin: attr(),
  xmax: attr(),
  ymax: attr(),
  zoomlevel: attr(),
  tooltip: attr(),
  tooltipDelay: attr(),
  layers: many('Layer', 'extents'),
  users: fk('User', 'extents')
}

Extent.propTypes = {
  xmin: number,
  ymin: number,
  xmax: number,
  ymax: number,
  zoomlevel: number,
  tooltip: string,
  tooltipdelay: number,
  layers: oneOfType([
    arrayOf(number),
    arrayOf(
      instanceOf(Layer)
    )
  ])
}

Extent.modelName = 'Extent'

我有相似的Layer模型，其定义如下：

const {
  string,
  number,
  bool,
  any,
  oneOfType,
  instanceOf
} = PropTypes

export default class Layer extends ValidatingModel {}

Layer.fields = {
  objtype: fk('Bo', 'layers'),
  layertype: attr(),
  label: attr(),
  layertypevalue: attr(),
  geometrytype: attr(),
  opacity: attr(),
  token: attr(),
  url: attr(),
  readonly: attr(),
  isFetching: attr(),
  'default': fk('LayerConfiguration'),
  status: attr(),
  enabled: fk('LayerConfiguration', 'enabledLayers'),
  highlighted: fk('LayerConfiguration', 'highlightedLayers'),
  disabled: fk('LayerConfiguration', 'disabledLayers'),
  filtered: fk('LayerConfiguration', 'filteredLayers'),
  editing: fk('LayerConfiguration', 'editingLayers')
}

Layer.options = {
  idAttribute: 'layerId'
}

我像这样为他们引导数据：

const victoriaExtent = Extent.create({
  xmin: 144.776008,
  ymin: -37.8458979,
  xmax: 145.101998,
  ymax: -37.6845001,
  zoom: 15,
  tooltip: 'Victoria',
  tooltipDelay: 0
})

const transformer = Layer.create({
  layerId: 1,
  label: 'Transformer',
  objtype: 'EQUI',
  layertype: 'PLANPLANT',
  layertypevalue: '0001',
  geometrytype: 'Point',
  opacity: 1,
  token: null,
  url: null,
  readonly: false,
  extents: [ victoriaExtent ],
  status: 'default',
  isFetching: false,
  'default': null,
  enabled: transformerEnabledConfig,
  highlighted: highlightPointConfig,
  disabled: transformerEnabledConfig,
  filtered: transformerEnabledConfig,
  editing: editingPointConfig
})

在州内，我发现虽然SessionBoundModel状态extents显示Layer ExtentsLayer，但该关系并未填充。 extent.layers关系模型未填充数据。

此外，当我访问范围时，我发现undefined属性为/ # telnet MY_IP_ADDRESS 80 HTTP/1.0 408 Request Time-out Cache-Control: no-cache Connection: close Content-Type: text/html <html><body><h1>408 Request Time-out</h1> Your browser didn't send a complete request in time. </body></html> Connection closed by foreign host。

我不明白为什么（还）但我发现从另一方接近这种关系（这是如何定义的）会产生结果。我将bootstrapping改为：

// Apply pagination

当我在.FirstOrDefault()选择器中使用以下语句时，使用这种定义方式：

const victoriaExtent = Extent.create({
  xmin: 144.776008,
  ymin: -37.8458979,
  xmax: 145.101998,
  ymax: -37.6845001,
  zoom: 15,
  tooltip: 'Victoria',
  tooltipDelay: 0,
  user: spilli,
  layers: [
    transformer
  ]
})

使用redux-orm引导多对多的关系
