我使用Devise创建了一个User模型,每当我使用rake db:migrate时,我都会遇到以下问题:
- == DeviseCreateUsers: migrating ==============================================
- -- create_table(:users)
- rake aborted!
- An error has occurred,this and all later migrations canceled:
- undefined method `database_authenticatable' for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x00000103fa1ff0>
- Tasks: TOP => db:migrate
- (See full trace by running task with --trace)@H_403_3@
我使用–trace函数运行完整的跟踪,但似乎无法弄清楚问题是什么.
这是迁移文件:class DeviseCreateUsers < ActiveRecord::Migration
def self.up
create_table(:users) do |t|
t.database_authenticatable :null => false
t.recoverable
t.rememberable
t.trackable
t.confirmable
# t.encryptable
# t.lockable :lock_strategy => :Failed_attempts,:unlock_strategy => :both# t.token_authenticatable
t.timestamps
end
add_index :users,:email,:unique => true
add_index :users,:reset_password_token,:confirmation_token,:unique => true
# add_index :users,:unlock_token,:authentication_token,:unique => true
end
def self.down
drop_table :users
end
end@H_403_3@
