Question

任何想法我怎么能重构这段代码？

case @fruit.actable_type
            when "Apple"
                redirect_to apple_path(@fruit.specific, :anchor => "comment_id_#{@comment.id}")
            when "Orange"
                redirect_to orange_path(@fruit.specific, :anchor => "comment_id_#{@comment.id}")
            when "Banana"
                redirect_to banana_path(@fruit.specific, :anchor => "comment_id_#{@comment.id}")
            end

主要问题是要指定我需要包含路径的锚点，我不能这样做：

redirect_to @fruit.specific, anchor: "whatever"

我尝试了很多东西，但我仍然无法重构：/

Answer 1

path_method = "#{@fruit.actable_type.downcase}_path"
anchor = "comment_id_{@comment.id}"
redirect_to send(path_method, @fruit.specific, anchor: anchor)

Answer 2

这样的事情对你有用：

anchor = "comment_id_#{@comment.id}"
prefix = @fruit.actable_type.downcase
redirect_to send("#{prefix}_path", @fruit.specific, anchor: anchor)

Rails：使用变量重构动态路径？
