如何將數組中的隨機字符串傳遞給視圖？

Question

在我的控制，我的定義位置的陣列，我用sample趕隨機字符串之一：

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

不過，我不知道在我的瀏覽器中顯示一個國家所需的代碼。

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 

現在視圖內 - index.html.erb

Country is <%= @location.sample %>
