How do I delete all entities from my local Google App-engine datastore?

Question

How can I remove all entities or reset the local datastore on my dev_appserver? I accidentally recursively called a function to create an entity when testing.

I am using the Google App-engine SDK on Vista with Python.

Answer 1

dev_appserver.py --clear_datastore myapp

See here for more info.

Shorthand version:

dev_appserver.py -c

Answer 2

A useful thing to do is to always specify --datastore_path, e.g. --datastore_path=test.datastore.

To delete it you can then just delete the file. You can also keep copies and swap them in and out. And the store will persist over reboots (when /tmp/ the default location for it on Linux anyway, gets cleared)
