title: StrongLoop Explorer Persisted Model Error
body: <p>I am trying to set up a sample strong loop application and I'm getting the following error when I try to tryout the post api using /explorer.</p>
  
  <pre><code>"Cannot call AccessToken.findById(). The findById method has not been setup.. The PersistedModel has not been correctly attached to a DataSource."
  </code></pre>
  
  <p>I ran through and installed slc loopback:acl with the following settings:</p>
  
  <pre><code>"acls": [
      {
        "accessType": "*",
        "principalType": "ROLE",
        "principalId": "admin",
        "permission": "ALLOW"
      }
    ],
  </code></pre>
  
  <p>However, these settings do not seem to apply to my model.</p>
