Question

我有以下$ resource factory：

app.factory "FeatureKey", ($resource) ->

  $resource "/api/v1/feature_keys/:id", { id: "@id" }

在指令中，我这样使用它：

@search = (term) ->
  FeatureKey.query(name: term).$promise.then (keys) =>
    if keys.length > 0
      @keys = keys
    else
      @keys = [{id: 0, name: term}]
    @current.key = @keys[0]

我想将大部分逻辑移到$ resource工厂，以便我的指令方法如下：

@search = (term) ->
  FeatureKey.search(term).$promise.then (keys) =>
    @keys = keys
    @current.key = @keys[0]

您只需让工厂使用search方法返回对象，而不是返回资源：

app.factory "FeatureKey", ($resource) ->
  r = $resource "/api/v1/feature_keys/:id", { id: "@id" }

  search: (term) ->
    r.query(name: term).$promise.then (keys) ->
      if keys.length then keys else [{id: 0, name: term}]

然后你可以像这样使用它：

FeatureKey.search(term).then (keys) =>
  @keys = keys
  @current.key = @keys[0]

如何使用自定义$ resource工厂方法重构此angular指令？
