it should still fix some issue I came up with a solution myself. I'm using Ember.computed.equal instead of a computed property. Here a part of the code
code :
isRoot: Ember.computed.equal('directory.content', null),

I wish did fix the issue. You can do this with the magic of Function#apply. apply calls a function by translating the passed array into an arguments list. (Function#call, on the other hand, takes a normal comma separated list of arguments). Try this:
code :
var func = function () { return this.get('properties'); };
var args = this.get('properties').concat([func]);

Ember.defineProperty(this, 'magic', Ember.computed.apply(this, args));
Ember.defineProperty(this, 'magic', Ember.computed('red', 'blue', func));

Hope that helps I'm quite new to ember and trying to write a computed property that checks whether or not a user is online based on their 'state' property, defined in the user model, and then returns a count of the number of users online. This is what I have been attempting, which is not working- , You need to use model.@each.state
code :
onlineUsers: function() {
  return this.get("model").filterBy("state", "online").get("length");
}.property("model.@each.state"),

With these it helps After some clarification from my previous answer, I realized you want to filter by console instead of filtering the assignedConsole values. My suggestion is to add a selectedConsole property on the controller, and display the array of assignedConsoles for the selected console.

will be helpful for those in need Imagine I have a component with 2 properties: How would I be able to create a computed property based on the localID property and the Ember.computed.filterBy macro ? , Rewrite your property as
code :
filteredData: function() {
  return this.get('data').filterBy('id', this.get('localID'));
}.property('data.@each.id')

it should still fix some issue You need to introduce search:'', in controller, and pass it down to posts component {{my-posts posts=posts category=category search=search}} and your clickCategory should reset search property when category clicked
code :
clickCategory(categoryId) {
   this.set('category', categoryId);
   this.set('search','');
}
    categoryPosts: Ember.computed('posts.[]','category', function(){ 
      return this.get('posts').filter(post => post.categoryId === this.get('category'));
    }),
