如何从mongodb查询中获取对象并在同一个控制器中使用它？目前我无法从中获取对象属性。例如，我的对象有一个月，下面是一个代码示例：

budgetsApp.controller('BudgetsCostbreakdownController', function($scope, $stateParams, $http, $location,$modal,$log, Authentication, Budgets) {

    // Get current budget
    $scope.budget = Budgets.get({ 
                budgetId: $stateParams.budgetId
            });

    $scope.chartObject.options = {
        'title': 'My Budget and Expenses for month of'+$scope.budget.budgetMonth //wont appear in my view .
    };
        //end chart
    }
);

Answer 1

假设您的代码中某处定义了Budgets对象等于$resource，您需要“等待”，直到数据从RESTful后端到达。

// Get current budget
Budgets.get({ 
  budgetId: $stateParams.budgetId
}).$promise.then(function(result){
  $scope.chartObject.options = {
    'title': 'My Budget and Expenses for month of' + result.budgetMonth
  };
});

Answer 2

为此目的使用回调Resource.action([parameters], [success], [error])

// Get current budget
Budgets.get({budgetId: $stateParams.budgetId}, function(response) {
    $scope.chartObject.options = {
        'title': 'My Budget and Expenses for month of'+ response.budgetMonth //wont appear in my view .
    };
});

从同一控制器中的mongo查询中获取对象值
