rake stopped working - no error message

Hi all...

Background:

I've been ramping up on RoR recently and started to resume the photos demo in the O'Reilly Book Ruby on Rails Up and Running. I had last worked on this just before creating a migration script and I was fairly comfortable at that point with understanding and creating migrations and using rake. I took a divergence from this practice project and even installed some other packages (macports, and some other graphics stuff).

Now I've returned to this project and I've completed the latest .sql changes and need to run rake migrate to go back to VERSION=0.

Problem:

I am running rake db:migrate just as I did in the past and I now just get this:

mbp-osx:~/Sites/Rails/photos patakijv$ rake db:migrate (in /Users/patakijv/Sites/Rails/photos) mbp-osx:~/Sites/Rails/photos patakijv$

I get no error messages... but it doesn't appear anything is happening.

What have I forgotten already about rake or what am I doing wrong?

How can figure out what the problem is if I don't have any error messages?

Thanks,

John

To go back to version 0, you need to specify it at the command line:

$ rake db:migrate VERSION=0

then

$ rake db:migrate

WARNING: That will destroy any data you have at your database currently.

When you execute just "rake db:migrate", and your database is already
at the latest schema version, no migrations are executed. You can look
at the current schema info at the corresponding table in the database.
For example, in MySQL:

Ah... ok - thanks!

I feel a little silly now... I could have sworn that I did that once but obviously I mistyped something... and I didn't realize I would get no messages if there was nothing to migrate.

Thanks again!
