如何将数组中的随机字符串传递给视图？

Question

在我的控制，我的定义位置的阵列，我用sample赶随机字符串之一：

class IndexController < ApplicationController 
    def index 
    @location = ["England", "Scotland", "Wales", "Ireland"] 
    random_location = @location.sample 
    end 
end 

不过，我不知道在我的浏览器中显示一个国家所需的代码。

Answer 1

使用Array#sample

class IndexController < ApplicationController 
    def index 
    # @location i_var will be available automatically inside the corresponding 
    # view of this action to the Index controller. 
    @location = ["England", "Scotland", "Wales", "Ireland"] 
    end 
end 

现在视图内 - index.html.erb

Country is <%= @location.sample %>
