I’m confused as to how nested routes and dynamic segments work with Ember. Below is how I’ve defined a series of nested routes for a House. I’ve been following the pattern for defining routes using Dynamic Models guide found here: [Specifying a Route's Model - Routing - Ember Guides](https://guides.emberjs.com/v2.15.0/routing/specifying-a-routes-model/#toc_dynamic-models) ``` this.route('houses'); this.route('house', {path: 'houses/:house_id'}, function() { this.route('show', {path: 'houses/:house_id/show'},); this.route('level-1', function() { this.route('master-bedroom', {path: 'houses/:house_id/level-1/master-bedroom'}); this.route('bathroom', {path: 'houses/:house_id/level-1/bathroom'}); this.route('patio', {path: 'houses/:house_id/level-1/patio'}); }); }); ``` I don’t understand why I have to keep specifying the entire path in order to get access to the `:house_id` dynamic segment. If I don’t specify the entire path with the dynamic segment `:house_id`, then trying to access the `:house_id` in the `params` object in the `model()` hook returns `undefined`. Is there a better way to do this? ---

Hi @johnnyicon, it seems like there are various concepts being mixed up here. According to the `router` you posted here, the path for `house.level-1.bathroom` is `/houses/:house_id/level-1/houses/:house_id/level-1/bathroom`. The `house.show` route also jumps out. Do you really want a `/show` route, or would you be better served by the `house.index` route? ---

To get the the `:house_id` param from the parent routes, you can use `paramsFor`, in your case `paramsFor(‘house’). The guides mention this in a section further down on the page you linked to: [Specifying a Route's Model - Routing - Ember Guides](https://guides.emberjs.com/v2.15.0/routing/specifying-a-routes-model/#toc_reusing-route-context). That will fix your issue with have to duplicate the paths. As @locks mentions, when you’re duplicating them like you have, you will also end up with a path that might not be what you expect it to be. ---

Also this is a great resource for figuring out routes: [ember-diagonal](http://alexspeller.com/ember-diagonal) You can paste your route config and see the resulting urls for each route. ---

Thanks for your response, locks. The example above was only to illustrate that I was having to use the `{path: ''}` on every router entry. ---

Thank you! This is exactly what I was looking for! I opted to use `modelFor` in my case as it saved me a step. Cheers! ---

Cheers! This is definitely useful! (One wonders why this isn’t part of the Ember Inspector… 🤔) ---
