One-time bindingと$resourceで気をつけること

More than 5 years have passed since last update.

前提

AngularJS1.3からOne-time bindingという最初の一回だけバインディングする仕組みが入った。
$resourceはpromiseではなく、先に空配列を返す。

問題

なので、下記のようにngRepeatをOne-time bindingにすると、空配列評価されて、何も表示されなくなったりする。
あ、下のindex()はquery()と読み替えて問題なし。

sample.coffee

angular.module("myApp")
.controller "SampleCtrl", ($scope, Group) ->
  $scope.groups = Group.index()

index.html
<div  ng-repeat="group in ::groups">
{{::group.name}}
</div>

解決

プロミスで処理しよう。
個人的には$resourceは出来るだけpromiseにしたほうがいいと思う。

sample.coffee

angular.module("myApp")
.controller "SampleCtrl", ($scope, Group) ->
  Group.index().$promise.then((groups)->
    $scope.groups = groups
  )
