如何在 ember 中生成哈希数组

Question

我是 EmberJs 的新手。

我有这个功能，

producerTypes: ( ->
  types = @get('model.registrations').mapBy('type').compact().uniq()
  //Here array of hashes to types and another model call requirements
).property('model.registrations')

如何在 ember 中制作哈希数组？

谢谢' :)

  producerRequirements: ( ->
    documentation = []
    types = @get('model.registrationsDocumentations').
              mapBy('producerType').compact().uniq()  //first map by type
    for producerType in types
      requirements = @get('model.registrationsDocumentations').
                          filterBy('producerType', producerType)   //second filter by producerType
      documentation.addObject(               //add to the array
        producerType: producerType,
        requirements: requirements
      )
    documentation
  ).property('model.registrationsDocumentations.@each')
