During development, you might find yourself needing to delete everything from a specific database table to refresh your data. You could drop the whole database and bring it back up again with
rake:db:drop, rake:db:setup, but that’s slow and indiscriminate.
Instead, boot up a console and call
delete_all on your model:
% rails c > Advisory.count # => 510 > Advisory.delete_all # => 510 > Advisory.count # => 0
I’ve been using this quite a bit while working on an idea related to security.dxw.com – more on that soon.
