Re: rake db:migrate "undefined method `default''" error
Could you post the migration code? Common problems include using a reserved word (mysql or ruby. Not sure, but default sounds like a common one. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

That was it, I forgot the colon before the "default":
class AddPrice < ActiveRecord::Migration
def self.up
add_column :products, :price, :decimal, :precision => 8, :scale =>
2, default => 0
end
def self.down
remove_column :products, :price
end
end
I''m all good now, thanks David, much appreciated.

Alexander,
When I tried that uninstall, I got:
While executing gem ... (Gem::InstallError)
cannot uninstall, check `gem list -d rake`
