Checking if a promise in AngularJS is empty or not

Hey there! I'm currently working on a piece of code that is designed to check if there are any users in the database. If it detects any users, it will display a list of them on a specific view. However, if there are no users found, it should redirect to a view where new user creation form is available. Unfortunately, the current logic for checking seems to be failing and I can't figure out what's going wrong.

users = Users.query();

users.$promise.then(
    function (data) {
        if (!data) {
            $location.url('/NewUser')
        } else {
            $location.url('/UsersList')
        }

    });

Answer №1

If no results are found, it likely returns an empty array. Make sure to verify the length of the data.

if (data.length == 0) {
   $location.url('/NewUser')
} else {
   $location.url('/UsersList')
}
