Are you sure you want to do this?

    Type 'yes' to continue, or 'no' to cancel: t   NAMEt   yest   usingsD  Database %s couldn't be flushed. Possible reasons:
  * The database isn't running or isn't configured correctly.
  * At least one of the expected database tables doesn't exist.
  * The SQL was invalid.
Hint: Look at the output of 'django-admin.py sqlflush'. That's the SQL this command wasn't able to run.
