javascript - 来自嵌套对象的 Angularjs $scope.object

Question

我有一个 $scope.currentUser 对象和一个嵌套的 OwnedCompany 对象，如下所示:

app.controller 'dashboardsCtrl', ($scope, Api, Auth) ->
  $scope.currentUser = Api.User.get(id: Auth.user())
  $scope.ownedCompany = $scope.currentUser.owned_company

{{currentUser}} 返回:

user: { 
  "name": "Ryan",
  "owned_company":{"name":"XYZ"}
}

{{currentUser.owned_company}} 返回:

{"name":"XYZ"}

但是 {{ownedCompany}} 返回 nil。

如何让 $scope.ownedCompany = $scope.currentUser.owned_company 工作？

解决方案

根据@mohamedrias 的回答，

app.controller 'dashboardsCtrl', ($scope, Api, Auth) ->
  Api.User.get(id: Auth.user()).$promise.then (currentUser) ->
    $scope.currentUser = currentUser
    $scope.ownedCompany = currentUser.owned_company

{{ownedCompany}} 返回:

{name:"XYZ"}

Answer 1

  $scope.currentUser = Api.User.get(id: Auth.user())

这是您获取当前用户详细信息的异步​​调用。所以它会在稍后重新处理。

要么必须使用promise ad put

  $scope.ownedCompany = $scope.currentUser.owned_company

在 then block 中。

否则在该对象上注册一个 watch 并执行分配。
