Query Firebase with AngularFire2 query getting only one object
<p>I have a Object Observable</p>

<pre><code>private Room = AngularFire.database.object(`/Rooms/`);
</code></pre>

<p>This observable has many values inside of it, but I have a child called <code>Empty</code>. That is set for <code>true</code> when empty and <code>false</code> when not.</p>

<p>I only want to query and get one room back from the observable. How do I go about doing this? Here is my first attempt without a query using <code>forEach</code> which is not something that I want to use.</p>

<pre><code>this.Room.subscribe(list =&gt; {
      list.forEach(snapshot =&gt;{
        if(snapshot.Empty == "true")
          console.log(snapshot);
      })
</code></pre>
