title: AngularFire2 how to use your own custom key instead of the auto generated one
body: <p>Currently I am using: </p>
  
  <pre><code>this.af.database.list('users').push(user);
  </code></pre>
  
  <p>How can I make the key of the object that is submitted be custom.
  So I want to be able to set the node of this object to the same uid of the registered user. I have access to this Id I just need to be able to know how to make the custom user objects node not be the auto generated id when pushing.</p>
  
  <p>Thanks</p>
