我对重新命名代码库中的变量感兴趣。它也是Rails中的表名。你是怎么做到的？
我知道在使用alias_attribute的地方有一些列重命名的东西。是否有类似的方法来重命名一个变量，而这个变量也是rails中的表名？

• 谢谢-谢谢
  schema.rb

ActiveRecord::Schema.define(version: 2015_05_19_181601) do

  create_table "todos", force: :cascade do |t|
    t.string "title"
    t.boolean "is_completed", default: false
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.string "session_user_id"
  end

end

个字符
我试过了

class Content < ActiveRecord::Base
  self.table_name = 'todos'
end

但是得到这个错误：

An error occurred while loading ./spec/decorators/todos_decorator_spec.rb.
Failure/Error: module Content
