Hi,

in the shop tutorial from the erlang-web wiki when adding the field
description are we changing the schema on the mnesia db?

When I run in interactive move db_init:init(). I get

db_init module, mnesia's schema already exists, if you want to delete it,
run mnesia:delete_schema/1

do I also lose the data while deleting the schema?

How to just add modifications to an existing mnesia db?

Thanks in advance.
