Rails 迁移版本问题:任何新迁移都不起作用
从今天早上开始,我遇到了 Rails 设备的奇怪问题。以下是我的 ls 和 rake db version 命令的输出。
hrishikesh@hrishikesh-ubuntu:~/git-public/personaldiary/db/migrate$ ls -1
20120110083934_devise_create_users.rb
20120110090514_create_posts.rb

hrishikesh@hrishikesh-ubuntu:~/git-public/personaldiary/db/migrate$ rake db:version
(in /home/hrishikesh/git-public/personaldiary)
DEPRECATION WARNING: require "activerecord" is deprecated and will be removed in Rails 3. Use require "active_record" instead. (called from /usr/lib/ruby/vendor_ruby/activerecord.rb:2)
Current version: 20120203034555
hrishikesh@hrishikesh-ubuntu:~/git-public/personaldiary/db/migrate$
如果我尝试添加任何新的迁移,rake db:migrate 会抛出错误,告诉我某些列已经存在,然后失败。
我失败的迁移代码在这里:
class AddConfirmableToDevise < ActiveRecord::Migration
def change
change_table(:users) do |t|
t.confirmable
end
add_index :users, :confirmation_token, :unique => true
end
end
我特别不想使用向上和向下方法,因为 这个
请帮忙。
From this morning, I am facing weird issues with Rails devise. Following is output of my ls and rake db version command.

hrishikesh@hrishikesh-ubuntu:~/git-public/personaldiary/db/migrate$
If I try to add any new migrations, rake db:migrate throws error that tells me that some column already exists, and fails.
My failing migration code is here:
class AddConfirmableToDevise < ActiveRecord::Migration
def change
change_table(:users) do |t|
t.confirmable
end
add_index :users, :confirmation_token, :unique => true
end
end
I specifically do not want to use up and down methods because of this
Please help.
