ngResource default parameters from promise

I have several rest services that looks like this

/user/:userId/resource/:resourceId

Most of the time the user wants to get his own resources (although sometimes he wants to get anther user's resource) so I want the default parameter to be the current user Id but I cannot save the UserId on a rootscope/service because if the user refreshes the browser this will be gone, so I want to do something like this:

$resource('/user/:userId/resource/:resourceId', { userId: getUserId, resourceId: '@id' })

the problem is that the getUserId() returns a promise:

function getUserId() {
    if (!$rootScope['user']) {
        $rootScope['user'] = UserService.get({ userId: 'current' })
    }
    return $rootScope['user'].$promise.then(function (user) {
        return user.id;
    }
}

how can I make it work for all services (as for now I'm just always chaining every resource service after the userId getter... is there a better way?

Use the browser session to store this non-sensitive data.

// Set the user object into the session as a JSON object
function setUser(user) {
    sessionStorage.setItem("user", JSON.stringify(user));
}

// Retrieve user object and parse the userID
function getUserId() {
    var tmpUser = JSON.parse(sessionStorage.getItem('user'));
    return tmpUser.userID;
}

Then your $resource will not have any promises being returned to it and you can access/modify the userID from anywhere in the code without polluting your $rootScope.
