Question

I have an error in my datastore that stops me from viewing it via the console. I want to delete the whole datastore and start again.

The following works on the development server:

db.delete(db.Query(keys_only=True))

When I run the same on the remote sever I get the following error (and the datastore is not cleared)

    illegal key.path.element.type: __Stat_PropertyType_PropertyName_Kind__

If you want to delete all the entities of a certain kind (or all kinds), the easiest way is to use datastore_admin, which is enabled in your live application’s admin console.
