Redirect With Params

Preserve query parameters through Rails routing redirects

Installation

Add this line to your application's Gemfile:

gem 'redirect_with_params'

And then execute:

$ bundle

Or install it yourself as:

$ gem install redirect_with_params

Add this line to your config/routes.rb:

Usage

Use redirect_with_params in place of redirect in your Routes file. This will preserve the query parameters in the redirect.

My::Application.routes.draw do
  get "some/route/:id" => redirect_with_params { |path_params, request| "/some/new/route/#{path_params[:id]}" }
end

Navigating your browser to /some/route/123?my_param=zebra&source=web will redirect you to /some/new/route/123?my_param=zebra&source=web

Optionally, you can specify a param whitelist:

My::Application.routes.draw do
  get "some/route/:id" => redirect_with_params(:source) { |path_params, request| "/some/new/route/#{path_params[:id]}" }
end

Navigating your browser to /some/route/123?my_param=zebra&source=web will redirect you to /some/new/route/123?source=web
