Rather sticky migrate problem
Here''s the problem... Typo has ~35 migrate scripts. Script 3 makes a
minor schema change, then migrates data to the new schema. For
instance:
add_column :articles, :user_id, :integer
Article.find(:all).each do |a|
a.user=User.find_by_name(a.author)
a.save
end
This makes sense... except that a revision 35 model has been
instantiated on a revision 3 schema!
