Edit: Below is my original question. After solving my problem, I thought I'd re-edit this so others may benefit. The root question is "A certain subset of textmate snippets aren't working."
Original Question: In Textmate, I can't use ruby on rails migration snippets like mtab⇥, mcol⇥, or t.⇥ in my db/migrate/ files. I've tried setting the file type as "Ruby on Rails" as well as "Ruby" and even "Sinatra" but have had no luck. These commands do work when I go through the bundle menu however. What am I doing wrong?
I had ActiveRecord::Migration misspelled so the snippets that rely on matching that string were failing! Always check the snippets source! :)
