EmberJS, WordPress REST API and categories and tags

I’ve started playing with ember and trying to combine the WordPress REST API and EmberJS. I‘m stucking with this problem: I want ember to show me all WordPress posts from a certain category or tag.

I have a route that shows me all categories routes/categories.js that are in the category model models/category.js. Now I need a route for each category routes/categories/category.js, that shows me all posts within a certain category.

post and category are two models, that I need to get combined I guess, but I do not know how ...

In routes/categories.js I have something like this

export default Ember.Route.extend({
  model() {
    return Ember.RSVP.hash({
      categories: this.store.findAll('category'),
      posts: this.store.findAll('post')
    });
  },
  setupController(controller, model) {
    this._super(...arguments);
    Ember.set(controller, 'categories', model.categories);
    Ember.set(controller, 'posts', model.posts);
  }
});

And in templates/categories.hbs this

<p>List of all categories in the model</p>
<ul>
    
        <li></li>
    
</ul>

Now I want to see all posts that are in this category routes/categories/category.js

export default Ember.Route.extend({
    model(params) {

        ...???...

    }
});

and in templates/categories/category.hbs ?

<h3>List all posts from the selected category</h3>
<ul>
    
        <li></li>
    
</ul>

Someone able to help with this?
