为什么我的示波器被缓存了？ [英] Why is my scope getting cached?

问题描述

我的范围如下：

scope :top, order('score DESC')

在我的控制器中使用如下：

It's used as follows in my controller:

def top
  @users = User.top
  render "list"
end

现在，似乎毫无缘由地缓存了该范围。如果我加载首页，添加一个用户并重新加载，则该用户不会出现在列表中。

Now, it seems that this scope is getting cached for no reason at all. If I load the top page, add a user and reload it, the user does not appear in the list.

但是，如果我这样做：

def top
  @users = User.order('score DESC')
  render "list"
end

结果不会被缓存。这是怎么回事我正在使用Ruby 2.0.0和Rails 4.0.0

The results don't get cached. What is happening here? I'm using Ruby 2.0.0 and Rails 4.0.0

推荐答案

发现了问题所在！范围应该定义如下：

Found what the problem is! The scope should have been defined as follows:

scope :top, order: 'score DESC'
