Question

我正在尝试为rails应用程序创建一个插件（fedena）rails版本是2.3.8。

在我的插件目录的db / migrate文件夹中创建了一个文件20140709100104_ultimo_theme.rb。

但是在安装插件时没有创建表。我已经检查了它进入课堂但它没有进入函数self.up，这是文件内容。

class UltimoTheme < ActiveRecord::Migration
  def self.up
    puts "creating table"
    create_table :ultimo_theme do |t|
      t.string   :theme_name
      t.boolean  :is_current
      t.timestamps
    end
  end
  def self.down
    drop_table :ultimo_theme
  end
end

作为rails中的新手，不知道它。

---------- EDIT --------

运行时出错

rake db：migrate：up VERSION = 20140709100104 --trace
