Ruby on Rails - passing parameters to 301 redirect in routes.rb

Question

I want to modify my existing routing “game” inside routes.rb, but due to SEO I also need to configure 301 redirects for old links.

My old routing:

match 'games/:permalink/:id/(:page)' => 'games#show' 

New routing:

 match 'gierki/:permalink/(:page)' => 'games#show' 

Here is the redirect I tried to do:

 match 'games/:permalink/:id/(:page)' => redirect {|params| "/gierki/#{params[:permalink]}" + params[:page].nil? ? "" : "/#{params[:page]}" } 

Above redirect does not work, here is the error:

 wrong number of arguments (1 for 2) 

Answer 1

Try this as follows:

 match 'games/:permalink/:id/(:page)' => redirect {|params,request| "/gierki/#{params[:permalink]}" + params[:page].nil? ? "" : "/#{params[:page]}" } 

And look if it works.
