For Google, Rails on Tiger not reading database.yml

It’s late but I thought I should post this for folks Googling…

If you’re trying to develop a Rails app locally on your Tiger Mac, and it seems like your app isn’t reading your username and password for your MySQL database server, here’s the issue.

Rails ships with a built-in all-Ruby MySQL adapter that doesn’t seem to pick up that username/pass. I’m not smart enough to tell you why, but it doesn’t.

So you’ll need to install MySQL, which you can get [here](

Then do:

sudo gem install mysql — –with-mysql-dir=/usr/local/mysql

That installs a native-built MySQL adapter. Your Rails app will pick up the DB config and all will be well with the world.

Update: I should have included the error message you’ll see. You’ll get something along the lines of this:

Permission denied for use ”@’’ (Using Password: NO)

And you’ll get this despite the fact that you have a username and password in the database.yml file.

    Where can I download the dictionary to translate all of that? Better yet, give me directions to the library with a hard copy….
