Ruby on rails Rails控制台应用程序初始化

今晚我创建了一个新的rails应用程序（4.2.5版），在

ActiveRecord

和

ActiveModel

中进行了一些实验。在修改一些gems代码后，我注意到在启动/重新启动rails控制台时出现了一些意外行为

例子

运行

bundle open activemodel

使用

p

语句修改方法，保存文件。（截断的代码段）

打开rails c调用将调用此方法的内容

Loading development environment (Rails 4.2.5)
2.2.2 :001 >
2.2.2 :001 > Product.new
"+++++++++++++++++++++++++++++++++++++++++++++++++++"
"+++++++++++++++++++++++++++++++++++++++++++++++++++"
"+++++++++++++++++++++++++++++++++++++++++++++++++++"

"+++++++++++++++++++++++++++++++++++++++++++++++++++"
"+++++++++++++++++++++++++++++++++++++++++++++++++++"
"+++++++++++++++++++++++++++++++++++++++++++++++++++"
"+++++++++++++++++++++++++++++++++++++++++++++++++++"
 => #<Product id: nil, in_stock: nil, name: nil>
2.2.2 :002 >

正在运行

重新加载并重新调用
产品。new
提供与步骤2相同的输出。退出rails控制台并使用
rails c
重新启动也会得到与步骤2相同的输出

期望问题 我希望退出rails控制台并重新启动将“重新初始化”rails加载过程（因此重新加载

ActiveModel

），但情况似乎并非如此。我发现看到所反映的更改的唯一方法是完全退出shell

如果有人能解释为什么我必须完全退出外壳才能看到我在gem中所做的更改？我不应该简单地退出/重新启动rails控制台吗

我从浏览中得到的印象是，调用

rails c

将启动启动序列，就像

rails s

谢谢

我看到这种设置影响了这种行为：

在config/environments/development.rb上

打开

config.eager_load = true

我见过这种环境会影响这种行为：

在config/environments/development.rb上

打开

config.eager_load = true

你残疾了吗？您可以尝试使用

spring stop

停止spring服务器。退出shell时，spring进程将被终止，因此这可以解释您看到的行为。@taglia，是的，它是spring。实际上，我刚刚从

Gemfile

中删除了它，并运行了

bin/spring-binstub--remove--all

。这只是我的一些实验。在那之后，我的行为和我预期的一样。谢谢看起来答案是，看起来答案是。你应该可以结束你的问题。你禁用了吗？您可以尝试使用
