restore them from source control :slight_smile:

if you just need the structure of the database then rake
db:schema:dump will dump that.

Fred, thanks a lot. it has create the schema dump. if I do db:migrate,
will it create all the tables using my current connection parameters?

Um… no? If you need to create a db according to the dumped schema
(on another machine, I presume), you’d use “rake db:schema:dump”.

And you are using source control, right? I hope?

Matt, I assume you wanted to type:

$ rake db:schema:load

For the OP, more options:

$ rake -T db:schema
$ rake -T db
$ rake -T

You were given an awesome advice, use source control. It can improve
your life quality immensely. BTW, if I would be asked which one, I’d say
git. YMMV.

Thanks for all the answers. I am yet to use source control. Although I
am sure source control is useful, i haven’t found ( or i didn’t try hard
enough :-)) any simple tutorial for learning to use git.

Source control isn’t just useful. It saves lives. And RAILS_ROOT/db/*
files. :wink:
