I am trying to duplicate a Rails 3 / MySql (working!) Application on another computer. I created schema.rb and data.yml, then used db: schema: load and db: data: load, and all this worked fine except for one thing. I had several indexes on my tables and the rake did not try to create them - I had to comment them out from schema.rb to force it to be generated, so I tried to translate them (as they were created in the original application!), and the rake is still dead. Here is the error message:
O:\Development\myapp>rake db:migrate
rake aborted!
An error has occurred, all later migrations canceled:
