How to remove unwanted GET parameters from URL in Ruby on Rails app?

Question

I have this index action in my Rails app:

class ProjectsController < ApplicationController

  def index    
    if %w[year quarter month].include?(params[:sort_by])   
      order = params[:sort_by]
    else
      order = "year"
    end
    ......
  end

end

Now if a user enters /projects?sort_by=foo it would be nice to have that GET parameter removed from the URL string immediately and redirect to /projects .

What's the best way to achieve that?

If there's anything else I can do to make my code safer, please let me know.

Thanks for any help.

您可以尝试通过在视图文件中添加JavaScript replaceState（）函数从浏览器的URL中删除不需要的GET参数。

history.replaceState({}, '', '/projects');
