Django extensions has reset_db command which is handy.

Monkey patching...

You have requested a database reset.
This will IRREVERSIBLY DESTROY
ALL data in the database "/Users/kracekumar/code/junction/db.sqlite3".
Are you sure you want to do this?

Type 'yes' to continue, or 'no' to cancel: yes
Reset successful.

You can use sqlflush for printing out database flushing command or directly use flush for removing all data from database.
