Migration Errors?

Rails
1

Hi there,

I just bought the Rails Recipes and PDF preview of the book. So far
it’s excellent. I decided to try Chapter 8 of the book regarding
tagging.

I’ve done migrations before, and I feel comfortable with them, however
this error stumps me.

antrover:~/RubyProjects/rlog dhoefler$ ruby script/generate migration

As you can see I’m running Locomotive on OS X 10.4.5. I have Rails
1.0. Right before I tried the migration I ran the following:

ruby script/plugin install acts_as_taggable

This is odd because I’ve done migrations before without any problem on
my Mac. All of a sudden they just stopped working.

Any ideas?

Thank you,
Dave H.

I know you need to get Edge Rails for it too work.

rake freeze_edge… is one way of doing it

I don’t know for sure if that is what is causing you the problem but
it will be a problem nevertheless :-). Try it.

Ok… I’ll have to try that.

For now I just deleted the whole acts_as_taggable directory under
vendor/plugins. I can now do migrations again. :slight_smile: I’ll come back to
that chapter at a later time.

Thanks for the info!

Hi Dave. Sorry I missed this when you originally posted it. You do
indeed need Edge Rails for acts_as taggable. The new version of the
book walks you through how to get onto Edge Rails.
