I have a metric table that I expect to be very large. It has a polymorphic association so that it can belongs_to other models that want to record some metric. I typically index association columns like this to speed up association loading. I've heard people talking about joint-indexing this association. This looks like: add_index :c...

Is there a rake command in Rails 3 to clone my development database data? I noticed rake db:test:prepare and rake db:test:clone are mentioned throughout various blogs, but running them seems to do nothing. Furthermore, rake -T shows no db:test cases.

I migrated our SVN repository to Git and pushed it to a central repository. We had a fair amount of tags and branches, but somehow we were not able to list and fetch those from a Git client. This was weird, because the tags and branches seemed to be available on the server. With help from a Jon Maddox blog post, a blog post from Marc...

I've pushed the app to Heroku, but when I'm migrating the db ($ heroku rake db:migrate), I keep getting the following error: rake...
I added a table that I thought I was going to need, but now no longer plan on using it. How should I remove that table? I've already ran migrations, so the table is in my database.
