Hello Azeem,
If you want to get familiar with task queues, you are encouraged to follow
a complete example. The one provided in documentation is: "Enqueue.java" on
github
<https://github.com/GoogleCloudPlatform/java-docs-samples/blob/master/appengine-java8/taskqueues-push/src/main/java/com/example/appengine/taskqueue/push/Enqueue.java>.
Related clarification is provided in the "Creating Tasks" on-line document
<https://cloud.google.com/appengine/docs/standard/java/taskqueue/push/creating-tasks>
.
In particular, the code portion dealing with task creation is a little more
complex:
import com.google.appengine.api.taskqueue.Queue;
import com.google.appengine.api.taskqueue.QueueFactory;
import com.google.appengine.api.taskqueue.TaskOptions;
Queue queue = QueueFactory.getDefaultQueue();
queue.add(TaskOptions.Builder.withUrl("/worker").param("key", key));
It seems that writing to the datastore fails. It might be advisable to
modify the line:
ofy().save().entity(post).now();
and modify it in similar to:
@Entity
class Car {
@Id String vin; // Can be Long, long, or String
String color;
}
that is by creating a class for the entity and instantiating it with a
"new" statement:
ofy().save().entity(new Car("123123", "red")).now();
More information is to be found in the github page
<https://github.com/objectify/objectify> for Objectify, under "Features".
