Auth.currentUser() always posts when called?

[JeffreyCheng92]

I have the onEnter passed into my router but Auth.currentUser() makes a post to users/sign_on.json even when I dont want it to. I just made a get request for the register page and it already tries to log in.. I checked Auth.currentUser() in the console and it returns a promise with a status of 0 and nothing else.

.state('register', {
            url: '/register',
            templateUrl: 'auth/register.html',
            controller: 'AuthCtrl',
            onEnter: ['$state', 'Auth', function($state, Auth) {
              Auth.currentUser().then(function (){
                // $state.go('home');
              }, function(error) {
                console.log(error)
              })
            }]

This is the post request made automatically after I make a get request for the user registration page.

Started POST "/users/sign_in.json" for ::1 at 2015-11-07 18:01:46 -0800
Processing by Devise::SessionsController#create as JSON
Parameters: {"user"=>{}, "session"=>{"user"=>{}}}

I think a solution would be for me to user Auth._currentUser which returns null but the docs say just to rely on the Auth.currentUser() promise instead..
