body: <p>I have an Offer object that I send to the server, when this offer is about to be created I need to send a push notification to the user. Offer has a pointer to User an the field is called "to".</p>
  
  <p><strong>How can I fetch an object from a pointer?</strong></p>
  
  <pre><code>Parse.Cloud.beforeSave("Request", function(request, response) {
  
      var userQuery = new Parse.Query("User")
  
      userQuery.get(request.object.get("to").id, {
          success: function (user) {
              console.log("user: ", user);
              var installationQuery = new Parse.Query("Installation");
              installationQuery.equalTo("user", user);
  
              Parse.Push.send({
                  where : installationQuery,
                  data : {
                      alert : "HEllo"
                  },
                  success : function() {
  
                  },
                  error : function() {
                      console.log("error finding installation: " + error);
