您好我有一个创建表的迁移(并向现有表添加一列)。

class CreateAdminModule < ActiveRecord::Migration
  def change
    create_table :admin_module do |t|
      t.decimal :no_of_devices_multiplier
      t.decimal :option_1_multiplier
      t.decimal :option_2_multiplier
      t.deciaml :option_3_multiplier
      t.decimal :option_4_multiplier
      t.decimal :option_5_multiplier

      t.timestamps
    end
  end

  add_column :admin_user_roles, :module_admin, :boolean
end

我正在使用mysql2 gem。当我运行迁移时,我得到了这个:

c:\Sites\site>rake db:migrate
-- add_column(:admin_user_roles, :module_admin, :boolean)
   -> 0.4726s
==  CreateAdminCirrus: migrating ==============================================
-- create_table(:admin_module)
rake aborted!
An error has occurred, all later migrations canceled:

undefined method 'deciaml' for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x3c00a80>c:/Sites/site/db/migrate/
20130911082405_create_admin_module.rb:7:in 'block in change'

C:in 'migrate'
Tasks: TOP => db:migrate
(See full trace by running task with --trace)

我很困惑,为什么我收到这个错误。我很确定decimal是一个有效的数据类型?我正在使用小数,因为我正在处理货币。

答案 0 :(得分:2)

拼写错误:

t.deciaml :option_3_multiplier

将其更改为:

t.decimal :option_3_multiplier
