How to delete entity from google App engine Datastore?

Question

I created an entity in the Google App Engine datastore.

How can I remove this entity?

Answer 1

You haven't specified which API you're using.

In Python it's like so:

db.delete(modelId)

In Java it should be like (I haven't tested this):

PersistenceManager pm = PMF.get().getPersistenceManager();

MyModel entity = pm.getObjectById(MyModel.class, modelId);
pm.deletePersistent(entity);

pm.close();

Answer 2

In python if you know the key it really simple:

db.delete(key)
