角全栈获取当前用户ID

Question

I'm using https://github.com/DaftMonk/generator-angular-fullstack .

I have 2 schemas:

• charts
  • title: String
  • datasets: Array
  • _creator: logged in user ID
• users
  • name
  • email
  • _id

When I console.log the current user returns

$scope.getCurrentUser = Auth.getCurrentUser();        
console.log($scope.getCurrentUser);

But when I try to console log the _id:

$scope.getCurrentUser = Auth.getCurrentUser();        
console.log($scope.getCurrentUser._id);

Returns

undefined

Can someone explain what I'm doing wrong?

Answer 1

Objects in chrome console get evaluated only when they are first opened.

This means that when you console.log an object like the return value of Auth.getCurrentUser() , the console displays a reference to it - this at the time of the log call contains a promise object, but it's most likely resolved by the time you open it on the console, so you see the property you're looking for.

On the other hand, when you're logging $scope.getCurrentUser._id , that's the result of a property lookup on the promise object - and it prints the current value of the property, which is undefined .

A note about clean code: your scope variable is called getCurrentUser, which makes one think it's a getter function, but it is infact the return value of a getter function. This is confusing.
