Ember adding check for transition call context (route/controller)

Question

In my Ember app, I have a common mixin/code which has a transition call

myCommonFn: function() {
//this.transition('someRoute') // Works if context is route
//this.transitionTo('someRoute') // Works if context is controller
}

Now because this function is common across multiple routes, it can either be triggered from a controller or route

My question is how do I ensure this works in both the cases? Meaning should I add a check using

this.constuctor() //Check if it is controller or route

OR should I do a null/undefined check for

this.transition() OR this.transitionToRoute()

What is the best way to make it work in all cases ?

Answer 1

If your mixin is applied everywhere, the simplest is just to check and fire. Additionally, if you have plans to upgrade, eventually controllers are going away, so this may just be a temporary fix.

var transition = this.transitionTo || this.transitionToRoute;

transition.apply(this, [arg1, arg2,.....]);;

You also could also extend your common mixin two more times and have a base version, a controller version, and a route version where you could specify route/controller specific functionality.
