是否可以使用Ohm和Redis DB Is Ruby来更新模型属性？

Question

我先来看看Monk和Ohm/Redis API，我有一个简单的问题。是否可以使用Ohm/Redis更新模型对象上的属性？

class Event < Ohm::Model
  attribute :name
  index :name
end

Event.create(:name => "A mistake made here...")

@event = Event.find(:id, 25)
@event.name = "I want to edit my mistake... but do not know how"
@event.save

使用Ohm，我可以执行以下操作

require 'ohm'
Ohm.connect
Ohm.redis.set :foo, "bar"
Ohm.redis.set :foo, "bat"

在文档中似乎找不到任何有关如何完成此操作的信息。提前感谢！

我不确定我是否完全理解您所询问的内容，但是使用以下代码可以更新该属性。

require 'rubygems'
require 'ohm'

Ohm.connect

class Event < Ohm::Model
  attribute :name
  index :name
end

Event.create(:name => "A mistake made here...")

@event = Event.find(:name => "A mistake made here...").first
puts @event.inspect
@event.name = "I want to edit my mistake... but do not know how"
@event.save
puts @event.inspect

@event2 = Event.find(:name => "I want to edit my mistake... but do not know how").first
puts @event2.inspect

然后我得到：

#<Event:1 name="A mistake made here...">
#<Event:1 name="I want to edit my mistake... but do not know how">
#<Event:1 name="I want to edit my mistake... but do not know how">

这样就更新了name属性。
