Emberjs: Conditional redirect in router

Question

Is there a way to have a conditional redirect in the Ember.js Router, without breaking internal consistency of the router?

Can you explain a little more why you're transitioning to a different route from connectOutlets? (I'm kind of a noob in ember, so maybe I just don't understand what you're trying to do) – Carob

By the way, routes now have a redirect: element you can override, it is in the current guide. – Allround

Answer 1

What you could do (as of today), is something like that:

root: Ember.Route.extend({
    index: Ember.Route.extend({
        enter: function(router) {
            var logged = /* get from appropriated source... */;
            Ember.run.next(function() {
                if (logged) {
                    router.transitionTo('loggedIn');
                } else {
                    router.transitionTo('loggedOut');
                }
            });
        }
    }),

    loggedIn: Ember.Route.extend({
        // ...
    }),

    loggedOut: Ember.Route.extend({
        // ...
    })
})

Do not miss the Ember.run.next as while you are in enter, the state transition is always pending, so you have to transition after that.

We use it as shown for authent, but you could imagine using it for whatever condition you have to...

If you do it on connectOutlets instead of enter you shouldn't need the Ember.run.next. – Civilly

do you have an example how to do it with connectOutlets? – Whiting

Well, the code is exactly the same, except the wrapping inside Ember.run.next(function () { ... }); – Valentin

Answer 2

The new router now includes a

beforeModel 

hook which you could over-ride to include conditional logic while transitioning to a route. The beforeModel hook will be called before the

model 

hook is called and it gets passed a

transition

object. You can decide if you want to redirect to another route using

transitionToRoute()

or you could abort the transition if you don't want to redirect by calling

transition.abort()

Depending on what you're trying to do, you may be looking for conditional transitions. This is covered in another stackoverflow question, the TLDR of which is to check this fiddle.
