Access the new ember router in the console

问题

Is there an equivalent function to grab the currentPath in the console with the new router in ember?

Before, I was able to do this:

App.router.get("currentPath")

However, it seems with the new router, you can't access the router in the same fashion. In fact App.router simply returns undefined.

Any help here would be greatly appreciated.

edit:

On a related note, because I can no longer access App.router and its properties, I can't figure out how to manually trigger state changes. For example,

App.router.transitionTo("some.state")

is no longer viable. What is everyone doing instead of this now?

回答1:

I found the answer buried in github issues. Re-posting here for posterity.

App.container.lookup('router:main').router

..returns the router. You can access transitionTo and handleURL to manually trigger state changes. Not exactly sure how to get the current state like before, but it seems like you can access the currentHandlerInfos property on the router to get an array of the current handlers (duh).

Hope this prevents someone else from ripping out their hair.

As of the latest build, you can find the router and change state like so:

App.Router.router.transitionTo('posts.comments');

App.Router.router.handleURL('/posts/comments');

I don't know if this is the recommended way (the router is very much a moving target at this point), but it works for now.

As of Ember 3.9, here is the new Router Service API docs.

https://api.emberjs.com/ember/3.9/classes/RouterService

import Component from '@ember/component';
import { inject } from '@ember/service';

export default Component.extend({
  router: inject(),

  actions: {
    next() {
      this.router.transitionTo('other.route');
    }
  }
});

Also here is an answer I posted about how to get the currentPath on the router service.

I think this should do

function getCurrentPath(){
  str = "currentState.parentState"
  arr = []
  arr.push(App.router.get("currentState.name"))
  while(true){
    name = App.router.get(str+".name");
    arr.push(name)
    str += ".parentState";
    if(name == "root"){
      break;
    }
  }
  return arr.reverse().join(".")
}

currentPath = getCurrentPath();
