Angular 2 new (RC1) router. Nested routes

Question

In beta version from the child component (let's say 'child1') you could tell your parent to load (navigate to) a different child component instead of current by something like that:

 _router.parent.navigate(['child2']);

('_router' is injected in constructor)

In RC1 there's no 'parent' property anymore so it seems like the you have to use _router.navigate() and provide the full url starting from the app root. Something like

/root/grandparent/parent/child2

Now, the question is if the child component is only aware about parent's routes but not about grandparent - how do you do this? Would be nice to use _router.navigate(['../child2']) but that gives me a weird errors like "invalid number of '../'.

The only way to get parent's url I found so far is that:

_router.routeTree._root.children[0].value.stringifiedUrlSegments

(you can also get there from OnActivate event)

but this looks just wrong to me. It also might differ depending on the number of parents/grandparents - I haven't tried yet.

So, is there a better way to do that or relative path should work and I'm doing something wrong?

Thank you.

Answer 1

I had the same problem. Just today I have found solution (it was in router.ts file here line:89)

/**
   * Navigate based on the provided array of commands and a starting point.
   * If no segment is provided, the navigation is absolute.
   *
   * ### Usage
   *
   * ```
   * router.navigate(['team', 33, 'team', '11], segment);
   * ```
   */
  navigate(commands: any[], segment?: RouteSegment): Promise<void> {
    return this._navigate(this.createUrlTree(commands, segment));
  }

You need to import RouteSegment and add it you your constructor

import { Router, RouteSegment } from '@angular/router';
...
contructor(private $_router:Router, private $_segment:RouteSegment){}
...

//If you are in for example child1 and child 1 is sibling of child2
this.$_router.navigate(['../child2'],this.$_segment);
